CAUTION
This product is a class 1 laser product that complies with 21CFR 1040 of the CDRH standard and
IEC825. This means that this machine does not produce hazardous laser radiation. The use of controls,
adjustments or performance of procedures other than those specified herein may result in hazardous
radiation exposure.
This laser radiation is not a danger to the skin, but when an exact focusing of the laser beam is achieved
on the eye’s retina, there is the danger of spot damage to the retina.
The following cautions must be observed to avoid exposure of the laser beam to your eyes at the time of
servicing.
1) When a problem in the laser optical unit has occurred, the whole optical unit must be exchanged as a
unit, not as individual parts.
2) Do not look into the machine with the main switch turned on after removing the developer unit, toner
cartridge, and drum cartridge.
3) Do not look into the laser beam exposure slit of the laser optical unit with the connector connected
when removing and installing the optical system.
4) The middle frame contains the safety interlock switch.
Do not defeat the safety interlock by inserting wedges or other items into the switch slot.

At the production line, the output power
of the scanner unit is adjusted to 0.57
MILLI-WATT PLUS 20 PCTS and is
maintained constant by the operation of
the Automatic Power Control (APC).
Even if the APC circuit fails in operation
for some reason, the maximum output
power will only be 15 MILLI-WATT 0.1
MICRO-SEC. Giving and accessible
emission level of 42 MICRO-WATT
which is still-less than the limit of
CLASS-1 laser product.
Caution
This product contains a low power laser
device. To ensure continued safety do not
remove any cover or attempt to gain access
to the inside of the product. Refer all
servicing to qualified personnel.

[5] UNPACKING AND INSTALLATION
1. Copier installation
2. Cautions on handling
Improper installation may damage the copier. Please note the following during initial installation and whenever the copier is moved.
Be careful in handling the copier as follows to maintain the performance of this copier.
Caution: If the copier is moved from a cool place to a warm place,
condensation may form inside the copier. Operation in
this condition will cause poor copy quality and malfunctions.
Leave the copier at room temperature for at least 2 hours
before use.
Do not drop the copier, subject it to shock or strike it against any
object.
Do not install your copier in areas that are:
• damp, humid, or very dusty
Do not expose the drum cartridge to direct sunlight.
Doing so will damage the surface (green portion) of the drum cartridge, causing poor print quality.
• exposed to direct sunlight
• poorly ventilated
Store spare supplies such as drum cartridges and TD cartridges in
a dark place without removing from the package before use.
If they are exposed to direct sunlight, poor print quality may result.
Do not touch the surface (green portion) of the drum cartridge.
Doing so will damage the surface of the cartridge, causing poor
print quality.
• subject to extreme temperature or humidity changes, e.g., near
an air conditioner or heater.

2. Outline of print process
Step-2: Exposure (laser beam, lens)
This printer is a non-impact printer that uses a semiconductor
laser and electrostatic print process. This printer uses an OPC
(Organic Photo Conductor) for its photoconductive material.
First, voltage from the main corona unit charges the drum surface
and a latent image is formed on the drum surface using a laser
beam. This latent image forms a visible image on the drum surface
when toner is applied. The toner image is then transferred onto the
print paper by the transfer corona and fused on the print paper in
the fusing section with a combination of heat and pressure.
A Laser beam is generated from the semiconductor laser and controlled by the print pattern signal. The laser writes onto the OPC
drum surface through the polygon mirrors and lens. The resistance of the OPC layer decreases for an area exposed by the
laser beam (corresponding to the print pattern signal). The beam
neutralizes the negative charge. An electrostatic latent image is
formed on the drum surface.

Step-3: Developing (DC bias)
Step-4: Transfer
A bias potential is applied to the MG roller in the two component
magnetic brush developing method, and the toner is charged negative through friction with the carrier.
The visible image on the drum surface is transferred onto the print
paper by applying a positive charge from the transfer corona to the
backside of the print paper.
Non-image area of the drum surface charged with negative
potential repel the toner, whereas the laser exposed portions
where no negative charges exist, attract the toner. As a result, a
visible image appears on the drum surface.

Step-5: Separation
Since the print paper is charged positively by the transfer corona, it
is discharged by the separation corona. The separation corona is
connected to ground.
Step-6: Cleaning
Toner remaining on the drum is removed and collected by the
cleaning blade. It is transported to the waste toner collecting section in the cleaning unit by the waste toner transport roller.
Toner is attracted over the shadowed area because of the developing bias.
AL-2041 COPY PROCESS 6 - 3
Step-7: Optical discharge (Semiconductor laser)
Start
Before the drum rotation is stopped, the semiconductor laser is
radiated onto the drum to reduce the electrical resistance in the
OPC layer and eliminate residual charge, providing a uniform state
to the drum surface for the next page to be printed.
1) Because the grid potential is at a low level, the drum potential
is at about -400V. (Carrier may not be attracted though the carrier is pulled towards the drum by the electrostatic force of 400V.
When the electrical resistance is reduced, positive charges on the
aluminum layer are moved and neutralized with negative charges
on the OPC layer.
2) Developing bias (-400V) is applied when the photoconductor
potential is switched from LOW to HIGH.
Semiconductor laser
3) Once developing bias (-400V) is applied and the photo conductor potential rises to HIGH, toner will not be attracted to the
drum.
Stop
The reverse sequence takes place.
Retaining developing bias at an abnormal occurrence
Function
The developing bias will be lost if the power supply was removed
during print process. In this event, the drum potential slightly
abates and the carrier makes deposits on the drum because of
strong static power. To prevent this, the machine incorporates a
function to retain the developing bias for a certain period and
decrease the voltage gradually against possible power loss.
Charge by the Scorotron charger
Function
The Scorotron charger functions to maintain uniform surface
potential on the drum at all times, It control the surface potential
regardless of the charge characteristics of the photoconductor.
Basic function
A screen grid is placed between the saw tooth and the photoconductor. A stable voltage is added to the screen grid to maintain the
corona current on the photoconductor.
Basic function
Normally, the developing bias voltage is retained for a certain time
before the drum comes to a complete stop if the machine should
stop before completing the normal print cycle. The developing bias
can be added before resuming the operation after an abnormal
interruption. Therefore, carrier will not make a deposit on the drum
surface.
As the photoconductor is charged by the saw tooth from the main
corona unit, the surface potential increases. This increases the
current flowing through the screen grid. When the photoconductor
potential nears the grid potential, the current turns to flow to the
grid so that the photoconductor potential can be maintained at a
stable level.
Process controlling
Function
The print pattern signal is converted into an invisible image by the
semiconductor laser using negative to positive (reversible) developing method. Therefore, if the developing bias is added before
the drum is charged, toner is attracted onto the drum. If the developing bias is not added when the drum is charged, the carrier is
attracted to the drum because of the strong electrostatic force of
the drum.
To avoid this, the process is controlled by adjusting the drum
potential and the grid potential of the Scorotron charger.
Basic function
Voltage added to the screen grid can be selected, high and low. To
make it easily understood, the figure below shows voltage transition at the developer unit.

the document table. The reflected light from the document is
reflected 4 times by No. 1 - No. 3 mirrors and passed through the
reduction lens to form images on the light-receiving surface of 3-line
CCD.
The light-receiving surface of the color CCD is provided with 3 line
scanning sections for RGB. Separate images scanned in each color
section are overlapped to complete color scanning. (When PC
scanning)

The image data sent from the MCU (image process circuit) is sent
to the LSU (laser unit), where it is converted into laser beams.
A. Basic structure
The LSU unit is the writing section of the digital optical system.
The semiconductor laser is used as the light source, and images
are formed on the OPC drum by the polygon mirror and fθ lens, etc.
The laser beams are passed through the collimator lens, the cylindrical lens, the polygon mirror, the fθ lens, and the mirror to form
images on the OPC drum in the main scanning direction. The laser
emitting PWB is provided with the APC (auto power control) in order
to eliminate fluctuations in the laser power. The BD PWB works for
measurement of the laser writing start point.

Since the upper heat roller is conductive, when using copy paper
that contains moisture and the distance between the transfer unit
and the fusing unit is short, the transfer current may find a path to
ground via the copy paper, the upper heat roller and the discharging brush.

Cassette paper feed operation
1) The figure below shows the positions of the pick-up roller, the
paper feed clutch sleeve, and the paper feed latch in the initial
state without pressing the Start key after lighting the ready
lamp.
The paper feed latch is in contact with the projection of the
clutch sleeve.
2) When the Start key is pressed, the main drive motor starts
rotating to drive each drive gear.
The pick-up drive gear also is driven at that time. Since, however, the paper feed latch is in contact with the projection of the
clutch sleeve, rotation of the drive gear is not transmitted to the
pick-up roller, which does not rotate therefore.
PFS
OFF
5) At this time, the paper is fed passed the paper entry detection
switch (PPD1), and detected by it. After about 0.15 sec from
detection of paper by PPD1, the tray paper feed solenoid (PFS)
turns on so that the clutch sleeve projection comes into contact
with the paper feed latch to stop the pick-up roller. Then the
pick-up roller rotates for about 0.15 sec so that the lead edge of
the paper is evenly pressed on the resist roller, preventing
against skew feeding.
PFS
ON
OFF
6) To release the resist roller, the tray paper feed solenoid and the
resist solenoid are turned on by the paper start signal to disengage the resist start latch from the clutch sleeve, transmitting
rotation of the resist drive gear to the resist roller shaft. Thus
the paper is transported by the resist roller.
7) After the resist roller starts rotating, the paper is passed through
the pre-transfer guide to the transfer section. Images are transferred on the paper, which is separated from the OPC drum by
the drum curve and the separation section.

3) After about 0.1 sec from when the main motor start rotating, the

the paper feed roller shaft, rotating the pick-up roller to feed the

latch is brought in contact with a notch on the clutch sleeve,
stopping rotation of the pick-up roller.

same time, the manual paper feed stopper opens and the manual take-up roller is pressed to the surface of the paper to start
paper feeding.
4) The lead edge of the transported paper is pressed on the resist
roller by the transport roller. Then the paper is stopped temporarily to allow synchronization with the lead edge of the image
on the OPC drum.
From this point, the operation is the same as the paper feed
operation from the tray. (Refer to 7-5 - 8.)

3) Set the print start position (AE lamp ON) (A), the lead edge void
amount (TEXT lamp ON) (B), and the scan start position
(PHOTO lamp ON) (C) to 0, and make a copy of a scale at
100%.
4) Measure the image loss amount (R mm) of the scale image.
Set C = 10 X R (mm). (Example: Set the value of C to 30.)
When the value of C is increased by 10, the image loss is
decreased by 1mm. (Default: 50)
5) Measure the distance (H mm) between the paper lead edge
and the image print start position.
Set A = 10 X H (mm). (Example: Set the value of A to 50.)
When the value of A is increased by 10, the image lead edge is
shifted to the paper lead edge by 1mm. (Default: 50)
6) Set the lead edge void amount to B = 50 (2.5mm).
When the value of B is increased by 10, the void amount is
increased by about 1mm. For 25 or less, however, the void
amount becomes zero. (Default: 50)
4) If the measurement value is out of the specified range, change
the set value and repeat the adjustment procedure.
The default value is 50.
Note: The rear edge void cannot be checked with the first sheet
after entering the simulation mode, the first sheet after turning off/on the power, or the first sheet after inserting the
cassette. Use the second or later sheet to check the rear
edge void.

3) Execute SIM 8-2. (The main charger output is supplied for 30
sec in the grid voltage HIGH output mode.)
This step adjusts the front surface printing (odd-number pages of a
document set) in the S-D mode copying and the leading edge position of an image on even-number pages in the D-S mode.
4) Adjust the control volume (VRG1) so that the output voltage is
580 ± 12V.
That is, it covers the adjustment of the second surface printing
mode (image loss at the front edge of an image) in which image
data is once stored in memory.
The image data is read, starting from its front end in the document
delivery direction (Reference direction of document setting in the
OC mode)and stored in memory.
This stored image data is printed starting at the printing start position, in the order of last-stored data to the first-stored data.
In other words, the front edge image loss of the image can be
adjusted by changing the document read end position.

This adjustment is made when the cassette paper size is recognized. The trailing edge void quantity can be adjusted by
changing the trailing edge image laser OFF timing.
2) Print start position (Duplex back surface) (SPF) 50-19 (PHOTO)
The size (length) of a document read from the SPF is detected,
the image at the trailing edge of the first printing surface is cut
to make a void area. (The adjustment of void quantity at the
time when the cassette paper size is not recognized.)
The paper void quantity should be first adjusted before the image
cut trailing edge void quantity (SPF) is adjusted.
2) Execute SIM 50-19 to turn on the PHOTO lamp and make the
printing mode in the S-D mode.
3) Remove and reinsert the cassette.
Note: Make sure to carry out this step before making a copy
during this adjustment.
4) Make a copy and check the void area of the scale on the
image.
Adjust the setting so that the void area is 2 - 4 mm. An
increase of 1 in setting represents an increase of 0.1 mm in
void area.

magnification ratio adjustment
Place a A4 paper (white chart) so that it covers the SPF scan glass
and the OC glass together, and close the SPF.
Note: Before performing this adjustment, be sure to check that the
OC mode adjustment in copying has been completed.
When simulation 53-08 is executed, the current adjustment value is
displayed as the initial display.
1) Put a scale on the original table as shown below, and make a
normal copy (100%) on the front and the back surfaces to
make a test chart.
* Default is 1. Adjustment range is 1 – 99. Adjustment unit 1 =
about 0.127mm
* If the values are kept as the default values, SPF scan is not performed properly. The front area of the proper scan position may
be scanned.
In case of AUTO, press [START] key, and the mirror unit scans
from the home position to the SPF scan position with the adjustment value displayed. The SPF glass cover edge position is calculated from the difference between the SPF glass cover edge and
the OC side document glass CCD output level. If the adjustment is
normal, the adjusted value is displayed. If abnormal, the error LED
lights up with the current set value displayed.
During the error LED is lighted, when [START] key is pressed
again, execution is performed again.

[Adjustment procedure]
1) Set the print start position (AE lamp ON) (A), the lead edge void amount (TEXT lamp ON)
(B), and the scan start position (PHOTO lamp ON) (C) to 0, and make a copy of a scale at
100%.
2) Measure the image loss (Rmm) of the scale.
Set C = 10 x R (mm). (Example: Set to 40.)
When the value of C is increased by 10, the image loss is decreased by 1mm. (Default: 50)
3) Measure the distance (Hmm) from the paper lead edge to the image print start position.
Set A = 10 x H (mm). (Example: Set to 50.)
When the value of A is increased by 10, the image lead edge is moved to the paper lead
edge by 1mm. (Default: 50).
4) Set the lead edge void amount to
B = 50 (2.5mm). (Default: 50)
(Example)
Distance from the paper lead edge
to the image lead edge, H = 5mm
When the value of B is increased by
10, the void is extended by about
0.1mm. (For 25 or less, however, the
void amount is regarded as 0.)

[Function]
When this simulation is executed, the current set correction value is displayed.
Enter the correction value and press [START] key to save the entered correction value. (Correction value range; 1 – 99, Default: 50)
For S-D mode front surface print, reverse memory copy operation is performed from the rear
edge of documents.
When, therefore, the print position adjustment of output images is required, adjust as follows:
In the reverse memory coping, when the document scan is made in the arrow direction, the output image is printed from the rear edge of scan image.
When, therefore, the print lead edge is shifted, set the reference chart so that the reference
position is on the rear edge, and use this simulation to adjust the set value so that the print lead
edge is matched.
Since printing is made from the image data most lately stored in memory to the lead edge data
from the print start position, the image lead edge adjustment is made by changing the end data
position stored in memory by the set value of this simulation.
Since it is performed by changing the scan end position, the image position adjustment is made
by changing the scan end position and the end data stored in memory.
