Comment [オブライエン1]: Duplex is
single pass, so why the difference – CIS width
limitation?
Comment [オブライエン2]: I’m sorry but I
don’t understand this
RE:
This item means “How degree of
magnification this ADF ‘(CIS) can apply to
image-data”.
And this description means “ADF (CIS)
actually can make image-date in 66.7% or of
cource 100% magnification ratio.”
Thanks – but I will ask for more about this

1.2.2 ORIGINAL PICK-UP

Original Detection
When an original is placed on the original tray correctly, the edge of the original pushes up
the feeler of the original sensor.
 Pickup Roller Shift up / down
When no original is placed, the pickup roller [C] is in the upper position (released). When the
original set sensor detects an original, the pickup roller lift motor [A] turns ON. When the lift
cam [E] releases the pickup lever [D], the pickup roller [C] moves down. To lift the pickup roller
[C] away from the paper, the pickup lift motor [A] turns on until the pick-up roller HP sensor [B]
turns off. Then the pickup roller lift motor [A] turns off.
Pickup Roller Down Timing
 When the machine detects that an original has just been placed
 When the trailing edge of an orginal passes the skew correction sensor (except for the
final sheet of an original). For A4 LEF / LT LEF, when the rear edge of the original passes
the registration sensor.
Pickup Roller Lift Timing
 When the leading edge of an original passes the skew correction sensor
 Just after the main machine power turns on
 When the ADF top cover is opened
 When there is an original jam

1.2.3 BOTTOM PLATE LIFT
When the machine detects that an original has just been placed, the pickup roller drops (the
pick-up roller HP sensor turns off), then the bottom plate lift motor [A] turns, and the lift lever [B]
lifts the bottom plate. The bottom plate lift sensor [C] (on the pickup roller holder) detects when the
bottom plate is at the correct position for original feed, and the motor [A] stops. When the sensor
[C] turns off during original feed, the bottom plate lift motor [A] turns on until the sensor turns on
again. This mechanism ensures that the top of the original is always at the correct height for feed,
even when the maximum number of sheets is stacked in the feeder [220 sheets (81.4 g/m2)]. At
the end of a job, the bottom plate lift motor moves the bottom plate down until the bottom plate HP
sensor detects it.

1.2.4 ORIGINAL FEED

Feed / Separation
The separation mechanism uses the FRR method, with a feed belt [A] and separation roller
[C]. When the pickup roller [B] feeds two or more sheets into the machine, the separation
roller [C] rotates backward to push all sheets back to the original tray except the top one.
Then one sheet of original remains and the separation roller rotates forward due to the torque
from the torque limiter included in the separation roller. Then the feed belt transfers the
original to the entrance roller.

1.2.5 SKEW CORRECTION
The skew correction sensor detects the leading edge of the original after it passes through the
separation area. When the leading edge reaches the entrance roller, the paper is fed a bit more so
that it bumps into the entrance roller [C], to make slack for skew adjustment.
For small paper (B6, A5, B5, HLT) or duplex printing, after detection by the interval sensor [E], the
original bumps into the pre-scanning roller [D] (this is a second skew correction, in addition to the
entrance roller).

1.2.7 ORIGINAL FEED PROCEDURE
When the machine signals the ADF to start feeding, the feed motor drives the pick-up roller, the
paper feed belt, and the separation roller, and these rollers feed the original.

After skew correction at the entrance roller, the entrance motor [G] and the relay motor [H] (relay
roller [I]) feed the original towards the exposure glass.
When the interval sensor [M] detects the original, the transport motor [K] drives the pre-scanning
roller and the white roller [J] in order to pass the original through the scanning area. (L:
Registration Sensor)
After the entrance roller starts to rotate, the feed motor drives faster to make the space smaller

between the former sheet (on the scanner) and the next sheet. However, if the sheet reaches
the pre-scanning roller at this speed, original buckle may occur due to the disparity of roller
rotation speeds. So when the skew correction sensor detects the leading edge, original
transport speed slows down so that the roller speeds match when the leading edge of the
original reaches the pre-scanning roller.
The exit motor [P] drives the exit roller [O] to send paper out to the exit tray when the exit sensor
[Q] detects the original.

Toner filling means sending toner from the toner cartridge to the sub hopper.
Here are explanations of the toner filling mechanisms.

When a toner cartridge [A] is placed, the shutter [C] on the cartridge opens and then the toner
transport port [B] also opens. When a toner cartridge [A] is removed, the shutter [C] on the
cartridge closes and the toner transport port [B] also closes. Each color cartridge has a
cartridge drive motor that drives an agitator and toner transport screws.

2. Sub Hopper
The sub hopper includes 4 transport coils [A] (larger 2 / smaller 2)
The larger coils agitate toner and the smaller coils transport toner to the downstream part of
the sub hopper.
The downstream part of the sub hopper is a toner transport path for supplying the
development unit with toner.
If the toner end sensor (in the sub hopper) detects a toner shortage in the hopper, the toner
cartridge supplies toner to the sub hopper.

3.2.2 TONER SUPPLY
Toner supply means sending toner from the sub hopper to the development unit.
Here are explanations about toner supply mechanisms.
1. Sub Hopper Drive
For each color, a stepping motor [A] controls toner supply to the development unit. When the
toner density sensor in the development unit detects that toner is needed, the sub hopper
drive turns on.
The two upstream transport screws [B] drive and agitate toner that arrives from the toner
cartridge.
2. Toner Transport / Supply
There are four transport coils in the sub hopper.
Toner from the cartridge is sent to the upstream transport coils [A] that agitate toner. Between
the upstream coils [A] and downstream coils [B], there is an open port [C] from which toner
moves to the downstream coils.
The downstream transport coils [B] don’t agitate toner but send it to the development unit
through the supply port [D] for the development unit.
The upstream transport coils and the downstream transport coils differ in their blade pitch. The

collected.
12/10
Mechanism Details
upstream coils [A] have a larger pitch to agitate toner easily. The downstream coils [B] have a
smaller pitch so as not to supply too much toner at one time; this also means that even when
the toner end sensor detects toner end, there is more toner held in the bottom of the sub
hopper than if the coils were larger. This means that even when the toner bottle becomes
empty, toner auto-supply from the sub hopper continues, and you can replace toner bottles
even during operation, which leads to reduced downtime.

4.2.1 SCANNER
An LED lamp [A] is used as a light source in this scanner. An LED lamp saves energy and is
superior in the charactaristic of light start-up so this machine employs not a xenon lamp but a LED
lamp. Light from the lamp passes to the CCD through the folloing route:
1st Mirror > 2nd Mirror > 3rd Mirror > Lens Block > CCD


LED Lamp
LED saves energy and provides better light at start-up so this machine employs not a xenon
lamp but a LED lamp.

CCD
The CCD collects the light that was reflected from the original and converts it to three color
analog signals (R, G, B).
The resolution of this CCD is 600dpi.

Shading Adjustment
A white plate for shading adjustment is attached to the back of the scale. Just after the power
switch is turned on, the machine performs shading adjustment, during which the scanner unit
moves to the white plate to emit LED light onto it in order to perform lamp modulation.
For normal (book mode) scanning, the machine performs shading every page regardless of
BW or color.
For ADF scanning, the machine performs shading before the 1st sheet of the original is
scanned regardless of BW or color, and then after that the machine performs shading for
following sheets at regular intervals (one minute or more).

4.2.3 ORIGINAL SIZE DETECTION
Two reflective sensors [B] are used as length detectors. Width direction is detected by a 3-point
pre-scan using the CCD.
The platen open/close sensor [A] is used to detect when original size determination is done.
Whenthe sensor state state canges from “not interrupted” to “interrupted”, the length is
determined and pre-scan starts at the same time. When the sensor state stays “not interrupted“,
the machine uses detection data that is read just after the [Start] key is pressed.

There is a difference between MPC8002SP / 6502SP and C5110S / C5100S in the method of
original transport from the ADF.

C5110S / C5100S
Transport Method
Non-contact Transport
Contact Transport
Descriptions
Merit
With the film attached on the
glass, an original doesn’t
contact the glass.
It hardly causes stripe tainted
image due to an original that
has foreign substances on its
face and taints the surface of
the glass.
Demerit
Comparing to the contact
method, due to dust that exists
in the path, stripe tainted image
occurs more often.
Aim
To improve prevention against
the occurrence of stripe tainted
image due to sticky foreign
substances.
Note
4. Be sure to replace the
sheet-through glass with
the film attached on the
glass.
5. When you attach the film
on the glass, you need to
keep the left scale attached
on the glass in order to
decide the location of the
film.*1
6. You can change the
method (contact method to
non-contact, or vice versa)
by replacing the parts.*1
While passing, an original
contacts the glass.
It hardly causes stripe tainted
image due to dust on the
glass, because the glass is
cleaned by contacting a
transported original.
More often than in the
non-contact method, stripe
tainted image occurs due to
foreign substances that
attaches on the surface of an
original and taints the glass.
Comparing to user of
machines for office, less user
of this machine tends to use
an original that has sticky
substances on its surface. And
considering to main user of
this machine, it’s important to
improve a prevention against
stripe tainted image due to
dust in the path

4.2.7 SCAN POINT SHIFT
When dust detection determines that dust exists, the scan point shifts in order to avoid the dust.
There are three scanning points; one is HP (Default), the others are 0.52 mm to the right (=b) from
the HP and 0.52 mm to the left (=c) from the HP. The shift is “a > b > c > a > b” at any time.

6.2.1 LD UNIT COMPONENTS
The VCSEL method is adopted in this machine, as in the ProC751 series, but the components are
different.
In the ProC751 series, there are VCSELs for each color and hexagonal polygon scanner mirrors.
But this machine has two VCSELs (one for K/C and one for M/Y) [B] and two four-sided
double-layered polygon scanner mirrors [A].
This machine uses VCSEL technology as ProC751 does, and realizes a high image quality
(approx. 4800dpi x 4800dpi). But the components and the control method are different from
those of the ProC751.
The polygon mirross [A] of this machine are smaller than those of the ProC751 series. But
this machine realizes not only the same image quality as the ProC751 series, but also a cost
reduction because only two VCSELs are enough.
Comment [n12]: Not Complete
[Writing Control Method Difference]
In the ProC751EX series, each VCSEL emits a beam for one color. While in this machine, with a
prism, one VCSEL can emit a beam for two colors.
In this machine, VCSEL emits beams alternately (K > C > K > C). A beam from VCSEL is divided
into two beams with a prism. One of the beams is used for K and heads to the upper polygon
scanner; the other of the beams is used for C and heads to the lower polygon scanner. When the
K-use beam heads to the drum, the C-use beam doesn’t head to the drum because there are
differences in reflective-surface directions between the upper polygon scanner and the lower
polygon scanner. While the K-use beam doesn’t head to the drum when the C-use beam heads to
the drum.
ProC751EX Series
Comment [n13]: I also cannot sure whether
20 LDs of 40 LDs make one color, or 40 LDs
make two colors. It seems difficult to find with
the original Japanese text. But I think maybe
the former (20LDs - one color) is correct.
Anyway, as you say, we need to ask someone
else to make sure.

Comment [オブライエン14]: I am not sure,
but I do not know how one beam can be split
to make two different data streams – they are
split just after leaving the LD unit – this
description seems strange
Comment [オブライエン15]: It seems to
me that out of 40 LDs in each unit, 20 are used
for each color – the prism will send 20 of these
beams to one color, and 20 to the other,
depending on the position of the beam in the
VCSEL array, it will be sent by the prism to
one of two locations (e.g, K or C) – this is just
a guess – I need to talk to project leaders


Charge, Discharge
The charge roller [A] equally charges the drum for each color (the potential sensor [D]
measures the charge). Before cleaning, LED emission [B] from the quenching lamp
discharges the surface of the drum [C].

Charge Roller / Cleaning Roller
The charge roller [B] applies charge to the drum. The charge roller [B] is separated slightly
from the drum surface and rotates in the opposite direction to the drum. The power pack
supplies the charge roller shaft with the charge that is applied to the drum.
Uneven charge can occur if the charge roller [B] is dirty. The charge roller cleaning roller [A]
cleans the charge roller to prevent this.

7.2.2 DRUM DRIVE
Each color drum has a drive motor [A]. The development unit and the cleaning unit have different
motors to remove fluctuations in load in order to improve the precision of color registration. Two
encoder sensors [C] monitor drum motor rotation and the signals are fed back to the drum motor
to control the motor speed.
Only the Pro has the drum HP sensor [D] for anti-banding improvement.
7.2.3 DRUM CLEANING
The lubricant brush [A], and the toner collection coils [B] and [C] are driven by the drum cleaning
motor through the gears.
A counter blade method is adopted for the lubricant blade [D] and the cleaning blade [E]. The
lubricant roller [A] rotates in the same direction as the drum in order to lubricate the drum surface.
The lubricant blade [D] keeps lubrication on the surface flat.
Used toner that is collected with the cleaning blade [E] and lubricant are sent to the used toner
transport area by the toner collection coil [C].
Lubricant and used toner are sent to the rear side and exited. There is a vibration plate in order to
prevent lubricant condensation. This vibration plate shifts up and down in accordance with the
rotation of the collection coil [B] and prevents the exit from clogging.

7.2.4 PG-FLUCTUATION REDUCTION TECHNOLOGY
To reduce PG-fluctuation that causes banding (50 mm pitch strips), the technology is employed in
this machine, which reduces the change degree of the relative-position between the drum and the
development R.
Pro C751EX/Pro C651EX has 16mm gap between the bearings of the development R and the
drum, while this machine has approximately 1mm gap on the same part in order to reduce the
change degree of a relative position when the development R receives sideways press or the PG
plate distorts because of inaccuracies in the manufacturing process.
Owing to the reduction, this machine holds steadier PG than Pro C751EX/Pro C651EX when
development R rotates, therefore banding is reduced.

Comment [オブライエン25]: Replace at

Comment [オブライエン26]: Here we
replace the entire drum cleaning unit
Does this mean?
10 km: Replace lubricant and roller
17 km: Replace entire unit (even though we
don’t have near end yet for the new lubricant)?
RE:
If you replace lubricant and the roller, the
feeler is lowered and reset. And then after
10km drum running, the near-end comes again.
But when even the toner near-end occurs but
no replacing lubricant and the roller is done,
and the end detection occurs, you need to
replace the entire unit.
So in other words, if you replace lubricant and
the roller every time at near-end, you don’t
need to replace the whole unit (maybe not
forever though).

Comment [オブライエン27]: So, we have
three things:
Feeler
10 km limit
17 km limit
Which determines near-end?
Which determines end?
The above description says near end is
determined by the feeler, but earlier it says 10
km limit – is the 10 km an approximation?
What about the 17 km – is that a counter?
Actually, if 17 km is end, 10 km seems a bit
early for near-end – or maybe 17 km is to
replace the entire unit even if the lubricant bar
is not near-end, as I said in an earlier comment.
RE:
Both 10km seem a suggestion from this
machine developer but the rest 7km seems not.
The feeler works up to about 10km. After
near-end, I think something like a counter
counts about 7km running.
So the feeler determines about 10km and the
rest 7km is counted by a counter in the
machine.
But I cannot be sure that there is a counter for
the rest 7km. So we need to ask someone else
to make sure.

In PP market, there is relatively large number of demands for banding correction and
color-variability correction because user sells output from the copy machine. As a counter
measure against these demands, only ProC5100S/5110S has the technology, DEMS
(Development Electric-field Modulation System).
In DEMS, an ID sensor that monitors an ITB detects periodical variation that causes
density-variability. And then with referring to the detection result, development bias and charge
bias is adjusted in order to determine the amount of toner attachment and to reduce

8.1.2 DEVELOPMENT DETAILS
Toner Supply System (Pre-mix Development System)
To keep image density steady, this machine adopts the development system where toner is mixed
with a certain amount of developer before writing and then used developer is replaced by new one
while operating.
When the existing 2-element developer is used, image quality varies gradually as a carrier
ages, and regular developer replacement is essential to recover image quality. So replacement
intervals are shorter and image quality possibly varies in every replacement.
The new toner supply method prevents carrier degradation in the developer unit by mixing a
small amount of carrier with supplied toner and replacing developer gradually. This also helps
to sustain developer longer and to stabilize image quality for a high speed copier. Toner
contains approximately 30% of mixed developer (the same rate in all colors).
a) Agitation Method
A 3-axis agitation method is adopted in this machine.
With three coils [C] [E] [F], toner that is transferred from the sub-hopper to the development unit is
mixed with developer, and then the mixed toner is transferred to the development sleeve [B]. The
amount of mixed toner and developer on the development sleeve is regulated by the doctor blade,
and the mixed toner and developer attaches to the surface of the drum.
If too much developer is supplied, the excess amount of developer is exhausted with the
developer collection coil [A].
The TD sensor [D] near the development auger [E] detects toner density.
b) Development Unit Drive
The development motor [F] drives the development sleeve, the three augers [B] [E] [D], and the
developer collection coil [A] through the couplings.
Each color development unit has a development motor [F] that drives each of the units.

Mechanism Details
BW printing.
In BW printing, YMC drum (color drums) doesn’t contact on the ITB.
The ITB contacts on only K drum (black) in the default position. In color printing, the transfer
belt [C] is pushed up with the image transfer lift motor [A] through the eccentric cam [B] in
order to contact on the color drums. In BW printing, only the K drum contacts on the ITB. The
Contact detection is performed by the contact sensors.
In color printing after BW printing, BW printed paper passes through out the ITB unit, and
then the image transfer roller lift motor [A] turns on and pushes up the transfer belt in order to
contact the transfer belt on the color drums (Feed timing is controlled to make a space
between the former passing paper and latter).

Image Transfer Speed / Belt HP
The Feedback control on the ITB speed is operated when the BW mode, the color mode, or
MUSIC operation in order to enhance the preciseness of color correspondences. In this
machine, the speed of encoder that is driven with the ITB is detected by the encoder sensor
[B] that is installed near the encoder. The encoder sensor [C] detects the speed of the
encoder attached on the ITB drive motor. These two detected speeds affect the ITB speed
control. For more details, see the “CVEC” explanation described below.
The belt HP sensor [A] detects the point on the belt as the belt home position.

Comment [オブライエン34]: What does
this thermal control do
RE:
This section is only introducing components
related to temperature or humidity. This is not
about mechanism so it might be better to move
to another section.
CVEC(Compensation function of belt speed Variation of Encoder roller Cycle)
CVEC (Compensation function of belt speed Variation of Encoder roller Cycle) means “a belt
absolute position stabilization technology” that controls the speed fluctuation of the ITB. This
technology is initially employed in this machine.
In the existing machines, a driven axis FB (feed back) method is employed where the speed
of an ITB is detected through the driven roller rotation and feed back controlled. In this
method, it is possible that the fluctuation in a speed detection occurs due to the shake of a
driven axis or the eccentricity of an encoder that is attached on a driven axis. Besides, the
existing machines curbs color deviation by relating station pitches with the circumference of a
driven roller, but it’ difficult to eradicate the occurrence of belt speed fluctuation and position
deviation completely.
In CVEC technology employed in this machine, there are two encoders on the drive roller and
the driven roller, in order to control the speed of the ITB. From the difference of the detections
from the encoders on the drive roller and on the driven roller, the speed fluctuation of the
driven roller comes out. From the data (the speed fluctuation), the phase amplitude of the
driven roller that affects the fluctuation rate is calculated. Then the FF (feed forward) control
where the drive control is done in anti-phase, is performed that realizes less than 50% of the
speed fluctuation rate comparing to the existing machines.

Overview
11. PROCESS CONTROL
11.1 OVERVIEW
In electro photographic process, writing process condition for keeping the image quality varies
due to the factors (humidity / temperature fluctuation, print mode (image dimension rate, P/J), and
toner / developer / drum aging-degradation). So it needs to determine the proper condition by
detecting the development ability of a machine at certain timing (development gamma).
Process control means controls that adjust image writing condition for keeping image density
steady. In this machine, there are two-type controls as follows;


Potential Control:
Controls development potential that is a gap between potentials for the drum and
development bias in order to keep targeted tone.
Toner Supply Control:
Controls the toner supply amount for the development unit in order to keep the amount of
toner that attaches on paper steady.
To perform process control correctly, a machine requires “initializing” at the initial installation
or at a replacement of the development unit / developer / the drum. “Initializing” performs the
parameter initialization for the process control in order to keep up targeted tone based on the
behavior (before aging-degradation) of a development unit, developer, and a drum.

11.3 INITIAL SETTINGS
”Initial setting” means a process to initialize the process control parameter in order to keep up
targeted tone based on the behavior (before aging-degradation) of a new development unit,
new developer, and a new drum.
It’s essential for a machine to perform “Initial settings” correctly at the initial installation or at a
replacement of the development unit / developer / the drum.
If not, process control cannot perform correctly and wrong image density (too much thin or
thick) / toner scatter in a machine possibly occur.

Comment [オブライエン38]: The order is
TS sensor initialization, process control,
MUSIC?
RE:
The first process is TD sensor initialization.
And then the image quality adjustment
(includes AC current adjustment, transfer
current adjustment, potential control, MUSIC)
Actually I cannot sure the order of the image
quality adjustments but maybe Taurus-c1’s
descriptions are helpful.
(The description form is somehow different but
the same meaning.)
Please refer to

Comment [オブライエン39]: Is there an SP
to check MUSIC results?
RE:
I think there’s no SP for MUSIC results.
I brought this SP list from the existing machine
TTP-ref (Taurus-c1). And in Taurus-c1 TTP-ref,
there seems to be no descriptions about
MUSIC results. Neither in the SP database.
Potential Control
11.4 POTENTIAL CONTROL
11.4.1 OUTLINE
Potential control is executed at prescribed times to perform adjustments in the copy process in
order to achieve the target image density and produce the best quality images. These
adjustments include changing drum charge bias, development roller bias, and LD power.
Gradation patterns are created at prescribed intervals and read by the four potential sensors (one
for each color) on the drum and the center ID sensor for the patterns on the ITB. The machine
uses these readings to calculate development gamma for each color.

Toner Supply Control
11.5 TONER SUPPLY CONTROL
11.5.1 OUTLINE
[0: Fixed supply]: The mode that fixes the amount of toner supply to the development unit. Do
not use this mode unless you need to use this mode as a troubleshooting.
[4: DANC Supply (with Vtref Correction)]: Choose this mode normally.
*DANC Supply = Divided image Active Noise Control (Image Divide Type Active Noise Control):
The mode in which the necessary amount of toner is supplied to the area where toner is
consumed in the development, in order to steady the toner density in the development.
If toner supply is calculated based on the amount of toner used in covered areas only, errors
can increase, especially when changes occur in ambient temperature and drum
characteristics. This makes it difficult to control toner supply only with pixel counts (pixel
proportion control) to maintain constant image density.
Rather than depend on pixel counts in covered areas, several ID sensor patterns (Default: 10
patterns) are created on the drum and ITB between sheets. The machine uses two readings
Vsg (reflectivity of the bare surface of the ITB in the patterns) and Vsp (reflectivity of the
pattern areas covered with toner) to calculate Vtref. The value of Vtref is then used to set the
toner reference voltage for the TD sensor. This reference voltage is frequently updated with
fresh readings of the patterns to stabilize the amount of toner in the development unit.
11.5.2 ID PATTERN DETECTION TONER SUPPLY
In this machine, several ID sensor patterns (Default: 10 patterns) are created on the drum and ITB
between sheets. The machine uses two readings Vsg (reflectivity of the bare surface of the ITB in
the patterns) and Vsp (reflectivity of the pattern areas covered with toner) to calculate Vtref. The
value of Vtref is then used to set the toner reference voltage for the TD sensor. This reference
voltage is frequently updated with fresh readings of the patterns to stabilize the amount of toner in
the development unit.
The target toner value is set in the following SP codes;
 K
: SP3-620-001
 YMC :
SP3-620-002~004
The default of the target toner values for each paper is as follows;


Plain (Bk):
Gloss (Bk):
0.378mg/cm2, Color:0.433mg/cm2
0.378mg/cm2, Color:0.389mg/cm2

12. PAPER TRANSFER ROLLER (PTR) UNIT
12.1 MACHINE DESCRIPTIONS
12.1.1 GENERAL
The ITB unit has transfer power packs for belt transfer and paper transfer. These power packs
take a role of biasing not only the image transfer rollers for each color but also the ITB bias roller
(upper roller) to transfer image on the belt to paper. The paper transfer roller (lower roller) drives
in accordance with the ITB bias roller.

12.1.3 PAPER SEPARATION
In this machine, the PTR [A] and the curvature factor of the ITB [B] are used, and AC / DC bias is
applied to the separation electrode plate [C], in order to keep separation ability steady.
12.1.4 PAPER TRANSFER ROLLER LIFT (PTR LIFT)
The ITB unit in this machine controls PTR lift in order to meet the following objects (the PTR roller
moves onto or away from the ITB slightly enough to always press itself):
36. Not to let the PTR contact to process control patterns on the ITB when a process control
applies to the ITB.
37. To prevent image transfer efficiency degradation, the PTR lowers before the leading edge of
thick paper comes into, in order to prevent shock jitter due to thick paper plunge. After the
leading edge comes into between the transfer rollers, a return control (lift) is done to nip paper
with the transfer rollers.
38. To reduce cleaning burden by toner input reduction that applies to the PTR.
39. To secure paper transfer efficiency by not letting the transfer rollers keep contacting where the
PTR may be concaved.
40. To keep an ITB run steady when its start-up. (enhancing a prevention of a belt slackness that
can cause a brush against other parts)
 Control Specifications
41. General
The PTR lift motor [A] drives the cam [B] of the ITB bias roller. The PTR lift sensor [C] detects
the actuator [D]. With this sensor [C], the machine judges whether the PTR contacts or not.
This detection affects the PTR lift control.
Detailed Descriptions - DRAFT

D135/D136/D137/D138
Machine Descriptions
As shown below, The PTR lift motor [A] rotates CW (clockwise) [1] or CCW (counter
clockwise) [2] in order to rotate the bias roller cam [B] that determines whether the PTR
contact on the ITB or not:
 Left: Contact State
 Right: Separated State
You can find whether the PTR is in the contact or the separated state with seeing the direction
of the flat face of the ITB bias roller shaft on which the bias roller cam [B] attaches.
[1]: Contact state
The flat face of the shaft directs to the left under.
[2]: Separated state
The flat face of the shaft directs to the right under.
In the “separated” state, the separation space [C] (indicates the space between the PTR and
the ITB) is 1.5 mm regardless of paper thickness.
42. The direction of the ITB bias roller cam
PTR Separation
The ITB bias roller cam [B] (bulge part) pushes the bearing of the PTR [C] down to separate
slightly the PTR [C] and the ITB [A].

45. Shock Jitter Cancel Mode
To prevent a “go into” shock jitter (this tends to occur when thick paper goes into between the
ITB and the PTR), this mode allows the PTR to separate from the ITB before paper goes into
between the ITB and the PTR. After the leading edge of the paper reaches the nip area, the
PTR becomes contact state. And then to prevent “go out” shock jitter (this shock occurs
because the paper goes out between the PTR and the ITB), the PTR becomes separated
state before the trailing edge of the paper goes out of the nip area completely (Default> Thick
1 ~ 4: “OFF” / Thick 5 ~ 8 “ON”).
*With default setting (shock jitter cancel mode: OFF), when paper that is thin but hard goes
into between the ITB and the PTR, shock jitter may occur. In this case, switch the shock-jitter
cancel mode on / off in the following SP codes:
SP1-023-001~078
Standard Paper
0:OFF/1:ON
User Setting Paper
SP2-841-001~100

*The timing of contact / separation can be adjusted in the following SP codes:
There is difference between the same kind of thick paper in its thickness and hardness. To
receive this difference, in this machine, only “User Setting Paper” is adjustable.
Contact Timing: Larger SP values mean slower contact timing. “go into” shock jitter could
diminish if you make the operation slower.

48. The PTR release cam [D] moves and the PTR [B] is released (separated).
Comment [オブライエン43]: What is shock
jitter cancel mode?
RE: 12/18
Shock-jitter means when paper plunges into
the little space nip between the ITB and PTR,
shock will occur (especially thicker paper).
This shock is called “shock-jitter”.
To cancel this shock,
The rollers (PTR lower) separate to make a
space not to occur a shock. When the leading
edge of paper comes on the nip point, the
rollers contact (PTR lift) and then separate
(PTR lower) at the trailing edge of paper
passing by.
Comment [オブライエン44]: What is the
purpose of the pressure release mechanism –
we already have the lift motor
RE: 12/18
This motor moves the PTR unit to the position
where the PTR unit works.
While the lift motor lifts / lowers the PTR in
the work area.
So I mean:
The PTR Release motor: Lifts up the PTR Unit
to let it work. And lowers the unit not to allow
it to prevent withdrawing the front drawer unit.
The PTR Lift Motor: Shifts up / down the PTR
to help it work properly.
12/19/12 Thanks – when does this motor
operate?
RE: 12/19
The PTR pressure is released (lowers the PTR
unit) when you put your hand in the flapper on
the main drawer unit (the lift-up of the flapper
is detected by a sensor.).
And the PTR pressure roller lifts the PTR unit
when you close the drawer completely.

12.1.6 PTR CLEANING
Bias Cleaning Method
 Residual toner lingering on the PTR [A] is electro-statically transferred to the ITB [B] in order
to clean the PTR.
Basic Operation of Cleaning Control
With the state that the PTR and the ITB contact, switching the polar character of an output from
the PTR in turn in order to clean the PTR by transferring lingering toner on the PTR to the ITB.
Switching minus output to plus output is one cycle. According to the operation timing, a certain
cycles are performed. There are four patterns of the operation timing as follows;
49. FC Mode: All Machine Type: Four cycles
Cleaning is done while starting-up print job in FC mode, or PTR contact ~ PTR bias applying

50. Bk mode: MPC6502SP/8002SP: two cycles / ProC5100S/5110S: four cycles
Cleaning is done while starting-up print job in BW mode, or PTR contact ~ PTR bias applying
for printing. Cleaning is not performed solo but performed while other process is being done.

52. Non-frame trailing edge mode: x cycle (ProC5100S/5110S only) (SP Settable) ← The settable
value is TBA.
Only in this mode, cleaning is done between every sheet of paper. Before and after a basic
cycle, no-image area current is output. The output times of no-image area current are affected
by the PTR regulation cycle times that is settable in the SP.
12.1.7 PTR DRIVE
The encoder sensor [B] detects the speed of the rotation for the feedback control to adjust the
speed of the PTR roller.
The PTR drive motor [A] drives not only the PTR but also the belt cleaning and the PTB.

Comment [オブライエン45]: Sorry –
cannot understand well – according to this
explanation, toner is sent back towards the ITB
when paper still passes through – I think the
customer doesn’t like it
RE 12/18
I corrected the descriptions. Cleaning is done
not when paper-passing, but when between
every sheet of paper (the time when paper
doesn’t pass by the ITB and PTR). I mean, the
space between the former paper and the latter
paper.

13.2 DETAIL
13.2.1 FUSING MECHANISM
a) Belt fusing is adopted in this machine.
b) The surface of the fusing belt is made from polymide and is covered by silicone rubber that is
coated by teflon.
The fusing belt is driven by the fusing roller (Φ52).
Fusing roller material
 MP C6502SP/MP C8002SP: Sponge rubber

The elastic layer of the fusing belt is thickened in order to let the belt enter indentations in the
paper that existing belts cannot be inserted into. This improved fusing belt imposes pressure and
heat equally on all parts of the paper, and dramatically enhances fusing efficiency.

After fusing warming-up finishes, the fusing motor turns on for a certain
time to keep the fusing temperature at a specified level (adjusted with
“SP1107-001: Heating R”, “SP1107-002: Pressure R”).
The machine increases the temperature of the hot roller and of the
pressure roller to reach “Paper Passing-start Temperature”.
While paper is passing through the machine.
After the last sheet of a job passes the fusing exit sensor, the machine
controls the fusing motor, IH heater, and the pressure roller fusing lamp
to keep the target temperature (target temperature is adjusted with
“SP1108-001: Heating R”, “SP1108-002: Pressure R”).
When the “After Paper Passing” state finishes, the machine turns to
the “Ready” state.
The machine controls the fusing motor, the IH heater, and the pressure
roller fusing lamp in order to maintain the fusing temperature (can be
adjusted with “SP1107-001: Heating R”, “SP1107-002: Pressure R”)
A specified time passes after fusing reload, and then the IH heater and
fusing motor turn off. At the same time, the pressure roller fusing lamp
turns on in order to keep the target temperature (can be adjusted with
“SP1107-006”) of the pressure roller.
A specified time (normal: 1 minute) passes after the machine turns to
the “ready” state, and then the machine cuts power supply for the IH

13.2.6 PRESSURE MECHANISM
The pressure roller has a release control mechanism to release fusing pressure when a job is not
in progress. This contributes to reducing deformation of the pressure roller.
In addition, the nip pressure is adjustable in 3 steps by changing the angle of the cam, depending
on thickness of paper.

When a job starts, the fusing contact motor [A] drives, the pressure cam [B] turns, and the
pressure roller unit [C] shifts up.
When a job finishes, the fusing contact motor [A] drives in the opposite direction, and the pressure
roller unit [C] shifts down and pressure is released.
With the actuators [D], the front and rear sensors near the axial points of the cam detect the
following:


Pressure Roller Sensor (Front): Detects the angle of the cam in 3 steps to control the nip
pressure
Pressure Roller Sensor (Rear): Detects HP
The fusing contact motor [A] is driven by a DC brushless motor with an encoder.
After the motor has applied pressure, it stays on because otherwise the roller rotation while paper
is passing would tend to release the pressure.

It is OK to say feeler for a part that touches the

13.2.9 CLEANING MECHANISM (CH-C1 PRO ONLY)
The Pro type has the cleaning web as C901 or C751EX series have. Taint attached on the fusing
belt is cleaned indirectly by the cleaning web unit [B] through the pressure roller [A], in order to
prevent tainted print (black spot).
The cleaning unit [B] removes dirt from the fusing belt through the pressure roller [A].
The cleaning web method (heatproof non-woven fabric) is adopted in the cleaning unit [B].
The cleaning web contacts the pressure roller [A] and wipes off toner and paper dust on the
roller’s surface while being rolled up by the web take-up roller [C]. The cleaning web [D] contains
silicone oil in order to lubricate the pressure roller and the fusing belt. The cleaning web is driven
by the fusing cleaning web motor [E], which turns on every time a certain number of sheets are
printed in a job, and rolls up a certain length of the cleaning web.
The web take-up roller [C] rolls up the used web.


Web Near-End
When the cleaning web consumption reaches the setting in SP1902-004, the operation panel
shows “Web Near-End”. The default (81%) in the SP means the web lasts for approximately
450k prints.
Web End
The cleaning web unit has the actuator [A]. As the web take-up roller [B] rolls the used web up,
the actuator [A] shifts down. When the web is all used up, the web end sensor [C] detects the
actuator [A]. The machine stops printing after this is detected.

Cleaning Web Sensor
The cleaning web unit set sensor [A] detects whether the cleaning web unit exists or not.
The cleaning web contact motor [B] rotates the axis on which two disks [C] are attached. The
disks [C] push up the cleaning web roller unit to make the cleaning web roller [D] contact on
the pressure roller. At this time, the cleaning web contact / separation sensor [E] detects the
actuator [F] on the axis and judges that the web cleaning roller contacts the pressure roller..

Counter Measure for Cleaning Web Jam
In the pro C5100S series, when small size paper jams, the pressure roller [A] drives in reverse
so the machine can detect the remaining paper. Then the remaining paper moves to an area
where it can be removed easily.
But if the pressure roller [A] drives in reverse while the web [B] contacts it, the web can
become wrapped around the roller. So to prevent it, the web separates from the pressure
roller when jam occurs.

13.2.11 FUSING HEAT-SHUTOUT / COOLING MECHANISM


Fusing Heat-shutout
To prevent the heat of the fusing unit from affecting the laser unit, this machine has cooling
pipes. Five cooling pipes [G] are integrated in the aluminum panel. The cooling pipes reach
the heat sink [B] that locates in the left-upper of the machine.
The heat pipe panel intake fan [A] cools down the heat sink [B] whose temperature rises up
because of the circulation in the cooling pipes. The heat pipe panel exhaust fan [C] sucks the
heat air out of the rear of the machine.
IH Coil Cooling
The IH coil cooling fan [F] that locates in the front side of the machine sucks in air to cool the
IH coil (IH unit) [E]. The sucked air goes through the IH unit [E]. Then the transfer / fusing
exhaust fan [D] sucks air out of the rear of the machine.
The transfer/fusing exhaust fan [D] also sucks out the heat around the PTR.
13.2.12 PRESSURE ROLLER COOLING (CH-C1 PRO ONLY)
The fusing pressure roller intake fan [A] sucks air out of the machine to makes air current under
the pressure roller [C], in order to cool the pressure roller down. The fusing pressure roller
exhaust fan [B] sucks air out of the rear of the machine.
This mechanism prevents the pressure roller from increasing its temperature. This mechanism
allows the machine to reduce the frequency of downtime due to the temperature increment of the
pressure in consecutive print.

in order. And then the operation panel shows paper remaining level that depends on which of
the sensors is interrupted first. If none of them is detected as an interrupted sensor, the panel
shows paper remaining level is 100%. Besides the paper end sensor judges wheter paper is
remaining or not in the right tray.

in order to open the end fence [C] that is closed when the operation finishes. The end fence
closed sensor [B] detects the open/closed of the end fence. When the fence is not closed, the
operation panel shows the request of placing stacked paper correctly in the tray.
Comment [オブライエン65]: I don’t
understand this part well – replace what? User
must do?
RE: 12/20
I intended to mean “the request of closing the
end fence”.
12/21 – sorry – I still don’t get it – does the
user have to close this fence?
RE: 12/25
Actually, this request alerts an user to place
stacked paper in the tray correctly. Because the
fence cannot close due to stacked paper that
prevents the fence from closing completely.
Certainly, I think this description is hard to
understand. So I corrected.

e) Left Tandem Tray Back Fence Shift
When the paper end sensor in the right tray detects paper-runout while the paper detecting
sensor [A] in the left tray judges that paper exists, the rear fence drive motor (DC motor) [B]
turns ON at the same time of right end fence movement, and then the left tray back fence [C]
moves to push stacked paper in the left tray to the right tray. When the left tray back fence [C]
moves and the rear fence drive sensor [D] turns ON the rear fence drive motor starts to drive
reversely. This operation stops when the paper push the home position sensor [E] turns ON.

Left Tray Lock
The left tray cannot be withdrawn while paper is pushed from the left to the right tray. When
paper push starts, the lock solenoid [A] turns ON and the lock latch [B] hooks on the rear
convexed part [C] of the left tray. After paper push finishes and the tray back fence returns
back to the home position, the lock solenoid [A] turns OFF and the latch [B] is released. This
mechanism prevents withdrawing the tray while paper moves.

g) Right Tray Lock
When the bottom plate is in the lowest position, the lock lever of the left tray latches on the
joint lever [A] of the left tray and both of the trays are withdrawn at once. The joint lever [A] lifts
itself due to its own weight, and the latch with the lock-lever is released. At this state, only the
left tray can be withdrawn when the bottom plate is being lifted or is in the feed operation
position. The bottom plate [B] of the right tray lifts and the joint lever [A] lowers under its
weight, and then the right tray is locked.

The registration rollers [B] [E] stop paper to align it and then the registration motor [C] drives
the registaration roller (lower) [E].
In this machine, by adding a motor only for the registration, this machine doesn’t need to have

Skew Correction
The skew correction in this machine is the same method as in D081/D082.
Paper that passes up through the relay transport part bumps onto the registration rollers. At
this time, slackness is made on paper, which lets the leading edge of paper sit parallel to the
registration rollers. Without sufficient slackness, the correction cannot be applied to paper
effectively.
You can adjust the amount of slackness by SP mode. (See the Service Manual
“Troubleshooting > Adjustment005:Registration”)
Lead-to-Lead Registration
To match the leading edge of an image and of paper, the registration roller stops in a
specified time and then drives again to adjust the timing when to transport paper to the
downstream section (transport timing). This process is the same as D081/D082.
You can adjust the transport timing by SP mode. (See the Service Manual “Troubleshooting >
Adjustment005:Registration”)

Paper Dust Collection
The dust collection film [A] contacts the registration roller (upper) [B] in order to collect paper
dust. This prevents involving paper dust in the following process.
18.2.2 PAPER THICKNESS / DOUBLE FEED DETECTION
The proper condition on transfer and fusing varies depending on type and thickness of paper. So
it’s important to choose correct thickness in order to keep print quality. It’s also important because
a fusing detection and a jam may occur when the machine feeds paper whose thickness is
different from its setting. To prevent troubles, this machine does the paper thickness/ double feed
detection.

Basic Operation
By using the thickness sensor (lever-type encorder sensor) [A] to measure and compare the
thickness of transported paper, the machine detects "paper type difference" and "double feed"
to stop paper transport operation.
* Remaining paper in the machine is removed by the same way as the normal jam removal
way.
Thicker paper pushes the thickness sensor largely as shown below.

Mechanism Details
How degree the thickness lever moves is detected by the encoder [A] on the lever. With
referring to the degree, the machine judges "paper type difference" and "double feed" to stop
paper transport operation.
100.
Thickness Detection
When 1st-paper reaches the thickness measurement part, the measurement in which the
location of the driven roller decides the thickness is done. And then the measurement result
and the thickness set-value are compared.
If the thickness is out of the range of the value, the machine judges as wrong-thickness paper
and stops transfer operation. (“J098” displayed)

19.2 MECHANISM DETAILS
19.2.1 SIDE-TO-SIDE REGISTRATION
In this machine, rollers in duplex paper path shift to perform side-to-side registration.
After the leading edge of paper passes by the edge sensor unit [A], the edge sensor [B] that waits
in the home position drives to the main-scan direction as the sensor shift motor [C] drives. And
then the sensor detects the edge of paper.
In case of paper that is less than 220mm feed-length (less than A4 LEF / LT LEF), after passing
the leading edge of the paper by the duplex exit roller [G], the duplex transport roller 4 [F] and the
duplex exit roller [G] shift to the main-scan direction according to the rotation of the roller shift
motor 2 [H]. And then, based on the pre-detected data by the edge sensor [B], the machine
corrects the main-scan direction of the paper position.
In case of paper that is more than 220mm feed-length (more than B5 SEF), in addition to the roller
shift motor 2 [H], the roller shift motor 1 [I] also drives at the same time. So the duplex exit roller
[G] and the duplex transport roller 2 /3 / 4 [D] [E] [F] all shift at the same time in order to correct the
position.
The amount of the registration can be adjusted with SP mode (See the Service Manual
“Troubleshooting > Adjustment005:Registration”).

Side-to-side Registration Method Difference (Between each machine type)
113. MPC7501/MPC6501 (Jogger Fence Method)
By the jogger fence, the registration correction is done and paper goes to the duplex
path. Paper registration applies at switch-backing. So when paper passes in simplex
(before image-transferring), paper position and the difference of spaces between the
former passing paper and the latter passing paper are not adjusted. The transport path
distance from the switch-backing area to the face / back image-transferring part is long
*Green: Registration area (jogger fence area)
114.
MPC8002SP/MPC6502SP//ProC5100S/ProC5110S (Roller Shift Method)
By detecting the edge of paper while paper passes through the duplex path, the
registration correction is done. Paper position adjustment applies after switch-backing.
So when paper passes in simplex (before image-transferring), paper position and the
difference of spaces between the former passing paper and the latter passing paper are
not adjusted. Compared to MPC7501/MPC6501, after paper adjustment, the transport
path distance from the switch-backing area to the back image-transferring part is shorter,
that means this type is superior to MPC7501/MPC6501 in paper transport stability.

ProC751EX/Proc651EX (Roller Unit Shift Method)
Regardless of feed / duplex, the registration correction is done when paper passes
through the shift unit. Both sides of paper pass thorough the mechanical registration part.
So this type has high stability for paper transport and high registration accuracy for both
sides of paper.


Paper Cooling
The paper cooling pipe roller [A] cools paper that is just output from the fusing unit.
The paper cooling pipe [A] has fins on the end of its shaft. The cooling fan [B] cools the pipe
fins in order to cool the entire pipe.
On the rear side of the paper cooling pipe, the heat pipe set sensor switch [C] is installed that
detects whether the paper cooling pipe unit is placed or not.

Straight Through Output (Face-up Output)
When straight through output, transferred paper from the fusing unit passes through under the
paper cooling pipe [A]. When the inverter entrance junction-gate motor [C] keeps driving the
CCW direction in a certain time, the inverter entrance junction-gate [B] is pushed down and
paper is sent to the exit roller [D] that transfers paper to the decurler unit.


Invert Output (Face-down Output)
In invert output (face-down output) operation, paper is transferred from the paper cooling pipe
to the inverter exit path with the inverter entrance junction gate [B]. The inverter entrance
junction gate motor drives to the CW direction in a certain time before it stops.
The rear edge of paper passes through the paper cooling pipe and the inverter entrance motor
[B] gathers its speed at the same time. And then, with the inverter entrance motor [B] and the
inverter exit motor [C], paper is output.
The inverter exit sensor [A] detects the rear edge of paper and the inverter entrance motor
stops. Then the inverter exit motor rotates in reverse to transport paper to the exit part (invert
transport).
In the exit part, the inverter exit motor [C] drives the exit roller [D] and the inverter exit roller [C]
in order to output paper.

exit sensor, please see D in the next section

Duplex Transfer
After the duplex inverter sensor [D] detects the leading edge of paper, the duplex inverter
solenoid [A] turns ON and paper goes to the duplex transfer part. The duplex inverter motor
[C] drives to send the paper to the inverting area. Paper passes through duplex transport
path via that of the inverter exit unit and the duplex unit.
Transferred paper, after the timer-time for duplex transfer control passes, is sent to the
duplex path with the duplex transport motor [E] drives inversely (switch-back operation).

Duplex Interleaving
The number of interleaving in duplex printing depends on the size of paper and there are two
following patterns;
 More than 139.7 mm to 220 mm size: 3-sheet interleaving
 More than 221 mm to 487.7 mm size: 2-sheet interleaving
Paper location and flow in 3-sheet interleaving pattern
The image transfer order in 3-sheet interleaving pattern is as follows;
1st sheet face-up → 2nd sheet face up → 3rd sheet face up → 1st sheet face down → 4th
sheet face up → 5th sheet face up → 3rd sheet face down → 6th sheet face up → 4th face
down → 7th face up

20.1 MECHANISM DESCRIPTIONS
With the switch installed on the inverter exit duplexing part, the left-under of the machine, you can
eject jam paper to a specified tray.
 With the left switch (red-arrowed), jam paper in the exit inverter path in the machine can
be transported to the paper exit tray.
 With the right switch (blue-arrowed), jam paper in the duplexing inverter path in the
machine can be transported to the purge tray.

Inverting (Purge)
When jam occurs, jammed paper that remains over the main machine to the drawer unit
(Paper feed part) is sent to the purge part to clear up.
When the duplex inverter sensor [A] or the inverter relay sensor [B] detects paper, the right
side of the main LED-SW is pushed to operate the following parts below (in order to send
paper to the purge part):
 Paper Exit Motor ON (CCW)
 Inverter Entrance Motor ON (CW)
 Paper Exit Inverter Motor ON (CW)
 Fusing Motor ON (CW)
*Except the case of jam caused by fusing wrong
 Exit Inverter SOL ON
 Duplex Inverter Motor ON (CW)
*At the time of Duplex Inverter Sensor ON
 Duplex Transfer Motor (CW) [In the opposite direction to normal operation]
*At the time of the duplex entrance sensor ON
In the inverter part, the purged paper sensor [C] exists that detects whether paper is there or
not.

DRIVE / TORQUE SENSOR PART
Used toner that is sent from the used toner under transfer falls into the used toner bottle [C] via
the toner collection transfer screw and the collection bottle transfer screw [A].
The operation panel shows “SC486” (Used toner bottle motor abnormal) where rotate torque of
the screw [A] in the toner collection part and the collection bottle transport screw [B] rises while
rotating speed downs. And then the used toner motor lock sensor [D] acts and the used toner
bottle collection motor [E] is stopped.
The used toner bottle motor lock is detected when some burden applies to the toner collection
bottle screw and feeler cannot rotate.

Used Toner Bottle Drive
The used toner bottle collection motor [E] drives the collection part transport screw [A] and the
collection bottle transport screw [B] through the gears.

Torque Detection Part
When any of the parts; the used toner collection screw [B], the lower inner transport screw [F]
(used toner transport pipe) gains the torque, the torque limiter slips and the photo interrupter
[D] detects the slip state.

22.2.3 EACH SENSOR DETECTION
The used toner bottle set sensor switch [A] judges whether the used toner bottle [B] is set properly
or not.
To detect the amount of toner in the used toner bottle, the used toner bottle near-end full sensor
[C] is installed. The used toner bottle near-end full sensor judges used toner bottle near-full when
the feeler [E] interrupts the used toner bottle near-end full sensor.
The full detection is occurred on a certain amount of sheets is copied (MP C6502SP/MP
C8002SP: about 30k, Pro C5100S/C5110S: about 12k) after the used toner bottle near full
detection.
Used toner falls in the bottle from front to rear, then rear to front in order not to accumulate used
toner disproportionately.
In a bottle placement, the magnet catch [D] attracts the plate that is attached on the used toner
collection bottle [B] in order to seat the used toner bottle correctly. At this time, the used toner
collection bottle pushes the used toner collection bottle set sensor switch [A] that detects whether
the used toner collection bottle is placed or not.
Besides, the feeler [E] that is attached on the used toner collection bottle interrupts the used toner
bottle near-full sensor

The buffer pass unit includes two sets of two exhaust fans and two sets of two cooling fans. After
copy job or a printer job has been received, these fans start at 0.1 second intervals in the following
order:
Upper Exhaust Fans > Lower Exhaust Fans > Upper Cooling Fans > Lower Cooling Fans
Air pulled in by the upper cooling fans passes through the inner side of the paper path, and goes
out of the machine through the lower exhaust fan. Air pulled in by the lower cooling fan passes
along the outer side of the paper path, and goes out of the machine through the upper exhaust fan.
These air flows cool down both faces of the paper, then the paper goes to the exit.
You can adjust the length of time that the fans operate after the end of a job with SP1932-001. (0

24.2.1 PAPER FEED
This machine has a feed belt and a reverse roller (FRR method).
The direction that the reverse roller turns depends on the frictional forces acting on it. When there
is a single sheet of paper between the feed belt and reverse roller, the friction between the feed
belt and the paper is greater than the reverse force from the reverse roller. So, the reverse roller
turns in the direction of paper feed.
If two or more sheets are fed between the belt and roller, the forward force on the second sheet
becomes less than reverse force from the reverse roller because of the low friction between the
two sheets. So, the reverse roller drives the second sheet back to the tray.
Finally, the feed belt and the reverse roller feed the paper into the machine.

26.2.1 BASIC OPERATION
This 9-pin mailbox connects electrically to the finisher with a 14-pin drawer connector. When a
print job starts, the main motor drives to rotate all rollers, and the specified bin receives the paper.

When the junction gate solenoid turns on, the gate switches and the tray receives the paper.
When the uppermost tray is selected, all solenoids stay off. When the last paper's trailing edge
passes the overflow sensor and the sensor turns off, the paper has gone to the tray, so the
selected tray's junction gate solenoid and the main motor turn off. Normally, the speed of paper
transport in this unit is nearly the same as in the finisher.

Tray Full Sensor
Paper Tray Full Detection Timing
When output from the paper overflow sensor is more than (T) seconds at the "High" level, full
detection will occur.
For example, at the lowest PPM (12 sheets / A3), when the sensor doesn't switch to "Low" by 40
sec after the detection, the print job will be stopped.
The machine determines the following depending on the result of the detection and the machine
state.

The leading edge of paper bumps on the stopper pawl [A] but goes further to make deflection
on its face. Then the deflected part is fed into the fold roller nip [B] and the fold is formed.

Double Sheet Fold Mode
One, two, or three sheet(s) of paper is (are) stacted on the pre-stack part. At this time, the
transport roller that makes a deflection on paper is evacuated so no deflection is made. The
fold plate [A] moves forward to press paper into the roller nip [B]. Paper goes into the roller nip
while being folded.


Z-Fold
Paper passes through the 1st folding part [A] without any treatment and bumps onto the 2nd
stopper [B] to makes a deflection on itself. With this deflection, paper is fed into the 2nd-fold
part nip and 1st fold is made.Then paper bumps onto the 3rd stopper [C] where paper is fed
into to form 2nd fold. Finally Z-fold is formed.

Half-fold
Single Sheet Fold: paper bumps onto the 1st stopper [A] and makes a deflection on itself
near the 1st fold nip [B]. With this deflection, paper is fed into the 1st fold nip [B] to be
half-folded.
Double Sheet Fold: 1 to 3 sheet(s) of paper is (are) pre-stacked while bumping onto the 1st
stopper [A]. The fold plate [C] presses paper into the 1st fold nip [B] and paper is folded to be
double half-fold paper.

Letter Fold-in [1] / Letter Fold-out [2] / Double-parallel Fold [3]
Single Sheet Fold: Paper bumps onto the 1st stopper [A] to makes a deflection on itself near
the 1st fold nip [B]. With this deflection, paper is fed into the 1nd fold nip [B] and 1st fold is
formed. Then paper bumps onto the 2nd stopper [C] and 2nd fold is formed at the 2nd fold nip
[D]. At this time, the location of the 1st stopper [A] and the 2nd stopper [C] varies depending
on the mode: Letter Fold-in / Letter Fold-out / Double-parallel Fold.
Double Sheet Fold: 1 to 3 sheet(s) of paper is (are) pre-stacked while bumping onto the 1st
stopper [A]. The fold plate [E] presses paper into the 1st fold nip [B] and 1st-fold is formed.
The following steps are same as the steps in single sheet fold.

Gate Fold
Paper bumps onto the 1st stopper [A] to makes a deflection on itself near the 1st fold nip [B].
With this deflection, paper is fed into the 1nd fold nip [B] and 1st fold is formed. After that,
paper bumps onto the 2nd stopper [C] and 2nd fold is made at the 2nd fold nip [D]. After
passing through the 2nd fold nip, paper bumps onto the 3rd stopper [E] and 3rd fold is made
at the 3rd fold nip [F] and double gate-fold is formed.

28.2.3 DOUBLE FOLD
*Mixed-loading is available within the range 55K ~ 70K
282.
The 1st paper goes into the pre-stack area which includes the TE stopper pawl [A] and
the 1st stopper [B].
283.
Paper pushes the TE stopper pawl [A] aside and open it to pass by. The pawl [A] moves
up when paper passes through a certain amount.
284.
At the time when the trailing edge of paper goes off the TE stopper pawl [A], the pawl [A]
switch its pawl to close.
285.
The leading edge of the 1st paper reaches the 1st stopper [B] and the TE stopper pawl
[A] switches its pawl to close in order not for the leading edge of the 2nd paper to bump onto
the trailing edge of the 1st paper. The 2nd paper goes into the pre-stack area.
286.
As the “step 2”, the 2nd paper begins to go into the pre-stack area while pushing the TE
stopper pawl [A] out. Then the pawl [A] moves up at the timing when a certain amount of the
2nd paper goes into.
287.
As the “step 3”, when the trailing edge of the 2nd paper goes off the TE stopper pawl [A],
the pawl [A] switch its pawl to close.
288.
The 3rd paper comes and the same operation (step.4 ~ 6) is applied to it.
289.
After 1 to 3 sheet(s) of paper is (are) stacked on the pre-stack part, the fold plate [A]
moves forward to press paper into the direction of the roller nip [B] to fold the stack.

When fold operation finishes, it is difficult to determine which stopper to be adjusted even if you
measure a skew of a fold end (Exclueding half-fold case). So confirm the direction of a skew by
measuring the length of each fold while paper is spreaded out.
*Except the case of half-fold mode, you need to determine which stopper to be adjusted from the
length of the 1st fold part that affects following fold parts.

After adding paper, when the upper cover is closed, the pickup solenoid [A] turns ON for the
pickup roller [C] to drop down. In this state, if none of the paper height sensors are interrupted, the
tray [B] shifts down until a sensor is interrupted. Then the tray shifts up. To check the tray [B]
position, the following process is done and then the tray [B] stops: the tray motor drives in reverse
until the lift sensor [B] is not interrupted → the tray motor drives forward until the lift sensor [B] is
interrupted.
After some sheets are fed, when the top of the stack drops so that the actuator leaves the lift
sensor [B], the tray motor drives forward again in order to lift the top of the paper stack to the
correct position for feed.

When the tray down button [A] is pushed, the tray motor drives in reverse and the tray shifts down
until the top of the paper stack reaches the paper sensor [B]. Then the tray motor [C] stops
(approximately 500 sheets can be added).
The lower limit sensor [D] detects the lowest point that the tray can shift.

30.2.1 FEED / SEPARATION
The feed unit includes a pickup roller, a feed roller, and a reverse roller (FRR feed method). It also
includes a φ20 grip transport roller.
A magnetic torque limiter is attached to the reverse roller. Reverse pressure is applied in
accordance with opening and closing of the tray.
Comment [n88]: RE:
Sorry, I wrote in quite oblique manner.
Simply this part means;
“This magnetic torque limiter shifts the
separation roller up/down responding to the
tray open/closed.”
OK, thanks, but this still seems a bit strange
(not the English, but the machine) – I will ask

30.2.2 FEED / SEPARATION OPERATION
The grip motor turns on and then the pickup solenoid turns on.
The feed motor turns on and the feed roller rotates. At the same time, through a relay gear, the
pickup roller rotates to feed the top sheet of the paper stack.
The reverse roller contains a torque limiter. The friction between the reverse roller and the feed
roller exceeds the limit of the torque limiter, and the reverse roller rotates with the feed roller.
When two or more sheets of paper are fed, the torque limiter makes the reverse roller rotate to
push the lower sheet of paper back to the tray.
When the feed sensor (reflective photosensor) detects paper, the pickup solenoid turns off and
the pickup roller lifts away from the paper, to reduce the resistance to paper feed.

30.2.3 TRAY SHIFT UP / DOWN
As shown in the picture below, the tray lift motor on the back of the tray drives a belt and pulley in
order to lift the tray.
When the tray is pulled out, the tray’s coupling with the tray lift motor is released and the tray shifts
down under its own weight.
368.
369.
Coupling Gear
Tray Lift Motor
After paper is added to the tray, the pickup solenoid turns ON and the pickup roller contacts the
top sheet of the paper stack. At this time, if the lift sensor detects the actuator, the lift motor turns
on in order to lift the bottom plate of the tray. When the tray shifts up, the pickup roller is lifted off
the surface of paper. When the actuator exits the lift sensor (sensor turns ON), the lift motor turns
off. After that, to enhance the accuracy of the bottom tray lift, the lift motor drives in the reverse
direction for 1 s (when reversing, the mechanism acts as a brake), 10ms after the lift motor stops.
If the tray is already at the correct height when the pickup roller moves down, this brake operation
is done immediately without lift. The top of the paper stack drops during printing, and when the lift
sensor becomes “interrupted”, the lift motor drives forward again to lift the paper stack.

Booklet Staple Transport
When paper begins to go through the booklet staple path, the shift roller unit [A] moves up to
its operating position in order to be ready to transport paper. The shift roller lift motor moves
the shift roller unit [A].
The shift roller drive motor rotates the shift roller [B] to transport paper to the bottom.
After the transportation has finished, the shift roller unit [B] moves up away from the paper
face. While the shift roller unit moves up, the shift roller [A] rotates to feed paper out to the
bottom. Then the shift roller unit drops to bump the stack junction gate [C] onto the edge of a
paper stack. With this operation, a paper stack is aligned.

Jogger
The jogger fence motor [A] drives to apply jogger operation in every job.
When a job starts, the jogger fences [B] move to a ready position that is varied depending on
the paper type. After that, jogger operation is applied in every job.

Bottom Fence Operation / Staple
Paper that is pushed with the stack junction gate bumps onto the bottom fence [B] in order to
align a paper stack. Then the booklet staplers [C] staple at the middle points of a paper stack.
After that, the bottom fence motor [A] moves the bottom fence [B] up to the position where a
paper stack is folded with the fold plate.

Fold Operation
The fold plate [C] fold a paper stack that is lifted up to the fold position with the bottom fence.
The fold plate motor moves not only the fold plate [C] but also the side-to-side shift fold roller
unit [E] because it needs to engage the operation of the fold plate [C] and the side-to-side
shift fold roller unit [E].
When the operation starts the fold plate [B] pushes a paper stack into between the rollers, the
side-to-side shift fold roller unit [A] slides on the upper path [D]. Both operations are done by
the fold plate motor. When the fold plate [B] pushes a paper stack fully, the side-to-side shift
fold roller unit [A] comes down to the lower path (position [C]) and presses the center of a
paper stack that is pushed by the fold plate [B].

Details
By the cam of the fold plate, the fold plate [C] keeps sticking a paper stack while the
side-to-side shift fold roller unit [A] presses the half of a paper stack (for details about the
press operation, see “Saddle Shaping Operation” described later). When the HP sensor [B]
turns on 2 times (the cam of the side-to-side shift fold roller unit rotates 2 times), the
operation of side-to-side fold is half done (the side-to-side shift fold roller unit is in the position
[D]) and then the fold plate motor begins to drive in reverse.
The side-to-side shift fold roller unit slides back on the upper path to the lower path. Then the
rest of side-to side fold is done while the fold plate returns to its HP where the fold plate HP
sensor [B] detects the fold plate.

In Japanese this is called “紙折りローラ”.
Maybe this is a new part. I think we need to
give a new name to it. (Here I named
provisionally.)
Saddle Shaping Operation
There are five steps in saddle shaping operation as shown below:
410. While sliding from the upper path toward the lower path, the side-to-side shift fold roller
unit [A] pushes the junction plate 1 [B] out and moves to the center of a paper stack.
411. As the side-to-side shift fold roller unit comes to the lower path ([C] position), the upper
roller of the side-to-side shift fold roller unit is pushed down. By the pressure of the spring,
the side-to-side shift fold roller unit [C]: can apply pressure to a paper stack and make
crease on it.
412. Appling pressure to a paper stack, the side-to-side shift fold roller unit [C] moves to the
front side of the machine (right side in the diagram below).
413. At the position [D], the upper roller of the side-to-side shift fold roller unit pops up from
the lower path to the upper path.

414. The fold plate motor drives in reverse in order to move the side-to-side shift fold roller
unit [C] to the rear side (left side in the diagram below) without the pressure to a paper
stack. Then the side-to-side shift fold roller unit [C] pushes the junction gate 2 [B] out and
comes down to the lower path again.
415. The side-to-side shift fold roller unit [C] returns to the HP [A] with applying the pressure
on the other side of a paper stack. In the HP [A], the upper roller of the side-to-side shift
fold roller unit pops up from the lower path to the upper path.

The inverter part has two of inverter plates that lead paper to one of three ways. When proof tray
output, the STM of the proof invert plate drives to send paper to the proof tray. In shift mode,
paper is sent to the shift tray without two of the STM driving. In staple mode, paper is sent to the
staple part with only the STM of the staple invert plate driving.



Shift Tray
In shift mode when the last printed paper output, the shift tray performs shift tray operation,
where the crank gear moves to the next HP position and the crank shaft moves left and right.
Then the shift tray plate shifts left and right. The shift amount is 15mm.
Up / Down
The shift tray performs up / down depending on the number (the stack height) of output paper.
The degree of up or down is adjusted to keep the paper face feeler on the place where both
the paper shift sensor and the staple paper face sensor are OFF state (Between the shift
sensor and face sensor in the picture below).

Shift Up
Paper is removed from the shift tray and the staple paper-face sensor turns ON. Then the shift
tray lifts up until the sensor turns “OFF”.
Shift Down <Shift Mode>
With stacked paper on the tray, the paper-face sensor is turned “OFF”. Then the tray up/down
motor turns “ON” to lift the tray until the sensor turns “ON”.
Shift Down <Staple Mode>
When paper output, the tray up/down motor keeps ON in a certain time to shift-down the tray.
Then until the staple paper face sensor turns “ON” to “OFF” (Home position), the tray is lifted
up to shift it to the home position. This operation is performed every time when paper output.
There are three of lower sensors but the tray lower sensor and the tray lower larger size
sensor are used for the machine display.

528. The rear edge of 2nd sheet of paper passes by the entrance sensor and the press tack
invert plate (Left) shifts to the right to open the 3rd path to send 3rd sheet to the path.
Then after the leading edge of the press tack sensor passes by the press tack sensor,
three sheets of paper (1st, 2nd, 3rd) are transferred to the staple tray. This method saves
the wait time for staple to enhance the copy production.

536.
Stack
Copy paper that is sent to the staple tray by the brush roller is conveyed to the staple tray. The
press tack size that holds the leading edge of the paper with using the leading stopper,
straighten stacked paper. It should be noted that, subsequent printed sheets later than 50
sheets are supported by the calling roller not to drop paper. After the staple output sensor was
OFF other sizes (A4: 55 ~ 65ms rear), the bumping motor drives a certain amount and
straighten the rear edge of paper with pressing it against the reference fence of the tray. At
that time, the brush roller performs paper guide to the stopper.
537.
Jogger
Jogger stack operation straightens the rear edge of paper. Then jogger operation affects the
side. ON signal of the main machine (copy start) orders the jogger fence to wait with a 7.2mm
off from each side width of paper. The rear edge of the paper that is conveyed passes by the
staple output sensor, and the jogger fence closes by 3.7mm inward to straighten the rear edge
of paper (Stack). Then the jogger fence closes by 3.5mm inward to straighten the side edge.
When the operation is completed, jogger fence state turns wait mode with a 7.2mm off from
each side width of paper until the next operation.
From the front and the rear edge, the plate spring extends to enhance the margin of
straightening.
538.
Paper Holding
To staple maximum 100 sheets of paper, the machine holds paper not to let it float. When the
jogger returns to the home position from the edge of paper, the paper holding motor operate
the paper holding plate to hold paper. The next following sheet turns the staple output sensor
OFF and the paper holding motor is turned ON to return the paper holding plate back to the
home position. The home position is detected with the paper holding HP sensor. This process
is done one by one per sheet, where both the paper holding moves both to the front and the
rear but the front and the rear paper holding holds the curl part of paper.
Because the front and the rear paper holding cannot operate at the area where a stapler is
there (Stapled area), the holding operates only in the case when a stapler isn’t there one by
one per sheet. The central paper holding operate constantly regardless the location of a
stapler.

32.2.5 STAPLE

Stapler
The drive motor in the stapler performs staple operation. If motor overload occurs such as
staple jam, operation panel shows jam detection. The stapler has a cartridge set sensor and a
staple end sensor which cause the panel to show staple supply requirement if staple end
(Staple shortage) occurs while coping. If staple jam occurs, copy operation stops. You can
remove a jammed staple with releasing the curved part in the picture below.
553. Staple Cartridge Set Sensor
554. Staple End Sensor

Staple Cut
This machine’s stapler uses longer staple needles to do a hundred sheets stapling. When a
few sheets, it cuts needles to eliminate remaining extra part. When staple operation, the extra
part of needles is cut. The cut extra part is send to the waste staple needle tray. After 1-job
end, the solenoid next to the stapler opens the lever to dump the cut extra part to the waste
staple needle popper. The popper downs and causes to show the waste staple needle full at
the time of tray full detection where the machine requires user to dispose of stored waste
needles.

Stapler Shifting
The stapler performs horizontal shift or rotation depending on the four of the staple mode.
 Staple Shifting
A rod supports the stapler which shifts to the horizontal direction with a timing belt. The
home position of the staple is the front side. When 2-area staple, the stapler staples the
front side first and then shifts to the rear side to staple there.

Output Exit Open/Close
This machine opens the output exit when output paper in order to output max one hundred
stapled sheets of paper to the tray.
When staple turns ON, the output exit open/close motor turns OFF to open the exit, where the
release motor turns ON after staple turns OFF. And the ejection belt drives and the ejection
paw attached on the belt sends the bulk of paper to the exit and the shift tray. After a certain
time from the staple OFF, the output exit open/close motor turns ON to close the exit, where
the bulk of paper is output to the shift tray by the exit roller.
Staple mode performs exit open/close operation when more than sixteen sheets of paper
need to output.
OFF timing for the output exit open/close motor depends on the disk on the output exit
open/close motor and sensor.

*MP1350 cannot punch
Punch applies one by one sheet. 2-hole punch applies to the rear edge of paper.
*By UP mode switch, 3-hole punch is enabled.
 Punch Drive
The punch motor drives the punch unit where the punch axis rotates in accordance with copy
paper transport to punch it. The punch axis waits at the home position. After the finisher
entrance sensor detects the rear edge of paper (OFF), the motor drives to punch at the
specified timing. The adjustment of the punch area is done by SP mode and the spacer.

Punch Waste Collection
Punch waste is collected with the popper installed under the punch unit. The popper unit has a
full detection sensor which detects full when punch waste is piled up to the sensor. In this time,
the operation panel shows full detection at the end of copy job.
And the punch waste popper has a set detection sensor to alert that “the popper is not set”
when the popper is not placed.

34.2.1 FOLDING
Receiving signal from the mainmachine turns the straight-pass motor and the folding motor ON
and then the upper stopper and the lower one shifts to the HP.
After that, the stopper shifts to the proper area depending on the size.
The flapper solenoid turns on and the flapper opens and then paper is sent into the folding unit.
On this way, the separation solenoid turns ON and the sending roller loses its sending power.
Paper bumps onto the lower stopper to correct its skew.
