EXPLANATION OF OPERATION
2.1
Electrophotographic processing mechanism
(1)
Electrophotographic process
The electrophotographic process is explained briefly below:
1. Charging
A voltage is applied to the CH roller to electrically charge the surface of the OPC drum.
2. Exposure
The LED head radiates light onto the charged OPC drum in accordance with the image
signal. The electric charge of the radiated part of the OPC drum surface attenuates
depending on the intensity of the light, thus forming an electrostatic latent image on the
OPC drum surface.
3. Development
Charged toner adheres to the electrostatic latent image of the OPC drum by electrostatic
power, and forms a visible image on the OPC drum surface.
4. Transfer
Paper is placed over the OPC drum surface and an electric charge is applied to it from
the back side by the transfer roller, so that the toner image is transferred to the paper.
5. Drum cleaning
The drum cleaning blade removes toner remaining on the OPC drum after the transfer.
6. Removal of Electricity
7. Belt cleaning
The belt cleaning blade removes toner remaining on the belt.
8. Fuser
Heat and pressure are applied to the toner image on the paper to promote its fusion.
1.
Charging
A voltage is applied to the charging roller, which is placed in contact with the OPC drum
surface, to charge the OPC drum surface.

Transfer
A sheet of paper is placed over the OPC drum surface, and an electric charge is given to the
paper from its back side by the transfer roller.
When a high voltage is applied to the transfer roller from the power source, the charge induced
on the transfer roller moves on to the surface of the paper through the contact part between
the transfer roller and the paper, the toner being attracted to the paper surface from the OPC
drum surface.

Fuser
The toner image which was transferred to the paper is applied heat and pressure as it passes
between the heat roller and the backup roller, and it is therefore fused onto the paper.
For the sake of safety, a thermostat is provided; it comes on to cut off the voltage supplied
to the heater if the heat roller temperature rises above a certain preset temperature.

Printing process
The paper fed from Tray 1 or Tray 2 is carried by the paper feed roller, register roller L and transport
roller. When the paper is fed from the MPT, it is carried by the MPT paper feed roller and register
roller U. Then, an unfixed toner image is created on the paper transported onto the belt sequentially
through the electrophotographic process of KYMC. Thereafter, the image is fixed under heat and
pressure as the paper goes through the fuser unit. After the image has been fixed, the paper is
unloaded to the stacker either face-up or face-down stacker, according to the outputting method
selected by opening or closing the face-up stacker.
While the above refers to the one-sided print operation of the printer, its operation in two-sided print
will be explained below.
When two-sided print is conducted, the paper that has passed through the fuser unit following first
one-sided print is sucked into the Duplex unit by the separator DUP. After entering the paper
reversal transport path, the paper is carried from there to the inside of the Duplex unit by the
inverting operation of the reversal roller. Then, after passed through the Duplex unit by the
transport roller that is located on the transport path inside the Duplex unit, the paper is fed along
the paper feed route of the Duplex unit to eventually merge the same route that comes from the
tray. From here on, the same operation as that of one-sided print of paper fed from the tray takes
place.

Outline of color drift correction
The color drift correction is implemented reading the correction pattern that is printed on the belt
with the sensor located inside the sensor shutter under the belt unit. This sensor is used to detect
and correct the pattern.
Automatic start timing of color drift correction:
• At power-on
•
When the cover is closed after it is opened briefly
•
When 400 pages or more have been printed since previous execution
A correction error may be issued due to an inadequate toner amount of the pattern generated,
a sensor stained with toner, deficient opening/closing of the shutter, or for other reasons.
However, even if an error is issued, it is not indicated on the operator panel. Therefore,
forcible color drift correction will have to be performed in the self-diagnostic mode (Subsection
5.3.2.6) to check the error indication.

Error checking methods and remedial methods
The color drift correction test function among the other self-diagnostic functions is employed to
check errors. (Subsection 5.3.2.6)
Remedial methods against different errors
• CALIBRATION (L or R), DYNAMICRANGE (L or R)
Check 1: If the above indication appears, check the connected state of the sensor cable
(FFC).
If the connected state is found abnormal, restore it to the normal state.
Check 2: Check to see whether the sensor surface is stained with toner, paper dust or any
other foreign matter.
If it is found stained, wipe it clean.
Check 3: Check to see whether the sensor shutter opens and closes normally, by the
MOTOR & CLUTCH TEST of the self-diagnostic function. If the shutter operates
imperfectly, replace the shutter unit.
• BELT REFLX ERR
Check 4: If this indication appears, check the cleaned state of the toner remaining on the
belt surface, in addition to making the above checks 1, 2 and 3. Take out the belt
unit, turn the drive gear located on the left rear side, and ensure that the belt
surface has been cleaned thoroughly.
If cleaning is not achieved perfectly and there still remains toner on the belt
surface after the drive gear has been turned, replace the belt unit.
• (Y or M or C) LEFT, (Y or M or C) RIGHT, (Y or M or C) HORIZONTAL
Check 5: If the above indication appears, check to see whether the toner is running short,
based on an NG-issuing color.
Replace the toner cartridge, as needed.

Outline of density correction method
The density correction is implemented reading the correction pattern that is printed on the belt with
the sensor located inside the sensor shutter under the belt unit.
Automatic start timing of density correction:
• If the environment at power-on is greatly different from the one in which previous print was
executed.
•
If at least one or more of the four ID count values are close to those of a new product at
power-on.
• When the ID count value exceeds 500 counts since previous execution.
A correction error may be issued due to an inadequate toner amount of the pattern generated, a
sensor stained with toner, deficient opening/closing of the shutter, or for other reasons. However,
even if an error is issued, it is not indicated on the operator panel. Therefore, forcible density
correction will have to be performed in the self-diagnostic mode (Subsection 5.3.2.7) to check the
error indication.

Principle of toner sensor detection
Toner LOW is detected by the toner sensor (Reflection sensor) installed inside the printer. The
shielding plate is mounted inside the ID and rotates in synchronization with toner agitation.
Moreover, the ID has a shutter fitted. The shutter is synchronized with the operation lever of the
toner cartridge, and the toner sensor can detect that the toner cartridge has been loaded properly.
Detection may not take place normally, and a toner sensor error may be issued, if the shield plate
or toner sensor is stained with toner, or if the ID unit and toner sensor do not remain exactly opposite
to each other in their positions.
Shutter
Shield plate
Toner Sensor
Principle of toner counter
After image data is developed to binary data which the printer can print, it is counted by an LSI as
a number of print dots. The amount of toner consumed is calculated from that count value, and the
remaining amount of toner is thus indicated. As opposed to this, the toner LOW detection by the
toner sensor is implemented when the toner amount remaining inside the ID unit physically
decreases to below a certain level.
Principles of ID, belt and Fuser counters
ID counter:
Belt counter:
Fuser counter:
43085101TH Rev.1
One count represents the value that results from dividing the amount of rotation
of the drum by three when three A4-size sheets are printed continuously.
One count represents the value that results from dividing the amount of rotation
of the belt by three when three A4-size sheets are printed continuously.
One count is registered when paper is shorter than the length of Legal 13-inch
paper. When paper is longer than that, the count number is determined by the
number of times the Legal 13-inch paper length is exceeded. (Decimal fractions

5.4.1 Precautions on the replacement of engine control PCB
1.
When EEPROM of the PCB to be removed is accessible
(When SERVICE CALL 105 [Engine EEPROM Error] is not displayed)
(1) Read the EEPROM information from the PCB to be removed by using the PU PCB
replacement function (Subsection 2.4.1.1.1 PU PCB replacement function in the Maintenance
Utility Operation Manual), and save it provisionally on the HDD of the PC.
(2) Copy the EEPROM information saved on the HDD to the EEPROM of the PCB to be newly
installed, by using the PU PCB replacement function (Subsection 2.4.1.1.1 PU PCB
replacement function in the Maintenance Utility Operation Manual).
Note!
2.
To download and write the EEPROM information by the maintenance utility, access the
EEPROM after placing the printer in the "Forced ONLINE mode" by the procedure
described below. Notice that, if the printer has an error currently issued, the error is also
displayed in the Forced ONLINE mode.
1. When turning on the printer, press and hold down the [BACK]+[MENU]+[ENTER]
keys, until "STATUS MODE" is displayed on the operator panel.
2. Thereafter, the "ONLINE" indication will appear if the printer is in normal condition. If
the printer has an error, it will be displayed. However, the printer is in ONLINE status
internally and, therefore, ready to hold communication.
When EEPROM of the PCB to be removed is inaccessible
If the PCB to be removed causes SERVICE CALL 105 (Engine EEPROM Error) to be displayed
on the operator panel, or the EEPROM data cannot be downloaded, first replace it with a new
PCB, and then, work by the following procedure using the maintenance utility:
(1) Setup of PU Serial Number
(Subsection 2.4.1.2 Setup of PU PCB of the Maintenance Utility Operation Manual)
The printer has a SAP Serial Number applied. The 12-digit SAP Serial Number is marked in
the top line of the serial number label, and is made up of two digits for production base, two
digits for manufacturing year and month, six digits for serial No. (Sequence No.), and two
digits for Revision.
• The PU Serial Number is a 10-digit number excluding the two digits for Revision from
the 12-digit SAP Serial Number.
• The number should be set on the "Subsection 2.4.1.1.2.1 PU Serial Number setup"
screen in "Subsection 2.4.1.1.2 PU PCB setup function" of the maintenance utility. •
Set in the “2.4.1.1.2 PU serial number setting” screen of “2.4.1.1.2.1 PU board setting”
of the maintenance utility.

• To specify a PU Serial Number, enter a 11-digit number prefixed with "0" (single-byte
zero). (Notice that, when the PU Serial Number is read, it is a 10-digit number.)
On the "PU Serial Number setup" screen, enter the 11-digit number resulting from
prefixing a single-byte zero to the 10-digit number which is obtained by excluding the
two digits for Revision, shown in the image diagram below, from the serial number on
the "PU Serial Number setup" screen.
[Other than for OEL]
Enter the 11-digit number resulting from prefixing "0" (single-byte zero) to the 10-digit number.
(Enter "0AE1234567.")

• The PU Serial Number is not output in the Printer Serial Number field of the Menu Map
header section. The CU Serial No. is output in this field. Therefore, after the PU Serial
Number has been rewritten, check it by reading the PU Serial Number again from the
maintenance utility.
• In the case of the OEL destination, the PU Serial Number is output, as a Lot Number, in
the Lot Number field in the bottom line of the Menu Map header section after the
configuration at the UK Plant. [See 1. (2) of Subsection 5.4.2.]
• When the PU Serial Number is read, a 10-digit number will be read and displayed.
(2) Switching to Shipping mode
When the engine control PCB has been replaced with a new one, the printer still is in the
Factory Work mode. Switch it to the Shipping mode.
• Make the switching on the "Subsection 2.4.1.1.2.2 Factory/Shipping mode" screen in
"Subsection 2.4.1.1.2 PU PCB setup function" of the maintenance utility.

Note!
When the EEPROM (engine control PCB) has been replaced, the service life information
of the belt, toner, IDs, etc., is necessarily cleared. Therefore, be aware that the service

5.4.2 Setup of EEPROM after replacement of SP1/TBH PCB
When the SPI/TBH PCB is replaced, it is necessary for the new replacement PCB to take over the
user-settings that the user has been using to that point, as well as the font install information. For
this, copy the EEPROM by the Maintenance Utility, and set up the CU Serial No. However, if
SERVICE CALL 40 is issued and the old EEPROM cannot be used, use the new PCB, and set the
CU Serial No.(See Subsection 5.4.2.2) and check the setup of destination (See Subsection 5.4.3).
Meanwhile, in the case of the TBH PCB, the EEPROM can be swapped directly between a new
PCB and an old one. In this case, the CU Serial No. setup and destination setup are not required.
5.4.2.1 Replacement of EEPROM after replacement of TBH PCB
The EEPROM of the TBH PCB is installed in the IC socket. Replace the EEPROM in the following
manner:
1. Remove the EEPROM and MAC address sticker label attached to the new PCB.
2. Insert a flat-tipped screwdriver in between the EEPROM of the old PCB and the IC
socket, and take out the EEPROM, seeing to it that the leads of the EEPROM are not
bent.
3. Install the EEPROM in the new PCB. In this operation, make sure that the silk print of
the EEPROM and that of the PCB match in the same direction.
4. Remove the MAC address sticker label of the old PCB, and paste it to the new PCB.

1) Change to a display that a changing situation of the toner sensor is confirmed from the
operation panel in the self-diagnosis mode.
Refer to Section 5.4.2.3 Switch Scan Test as for how to display the operation panel.
2) When taking out an ID unit and toner cartridge (TC) from the device, there is a window on
the observers’ right from the device, in a position across to the side of the TC.
In that window, a toner sensor is located.
3) Hold up a piece of white paper against a sensor in a place within 3mm from a sensor
window.
