2. Operational explanation
2.1 Electrophotographic process mechanism
(1) Electrophotographic process
The following describes the overview of electrophotographic process.
1. Charging
Equally charge the surface of image drum by implying negative voltage to the
charged roller due to negative charge.
2. Exposure
The light from LED Head is exposed on the negative-charged surface of image drum.
The surface electrical potential of the exposed part of image drum surface becomes
lower. Then forms electrostatic latent image.
3. Development
Negative-charged toner is attracted to the electrostatic latent image due to
electrostatic while touching the image drum. Then forms viewable image.
4. Transfer
Overlap paper on the surface of OPC drum, from the backside of paper transfer
toner image to the paper by applying electrical charge by transfer roller.
5. Drum cleaning
The remaining toner on the image drum that is not transferred is made to be
equable by cleaning roller. And is temporarily attracted to the cleaning roller due to
electrostatic.
6. Fusing
The toner image that is transferred to paper is fused on paper by heat and pressure.

Fig 2.1.1
2. Exposure
The light emitting from the LED Head will be exposed to the negative charged image drum. When
the surface electric potential of exposed part of the image drum goes to decrease, the electrostatic
latent image complying with image signal is formed.
Image drum is coated by basic layer (UL), charge generating layer (CGL), charge transferring layer
(CTL) on the basic material aluminum. The thickness of the organic light sensor (OPC) that is
consisted by CTL and CGL is approximate 20µm.

3. Image development
Toner is attracted to the electrostatic latent image on the image drum surface, then the electrostatic
latent image changes to toner image.
1 As the roller on the supply spot of toner rotates while scrubbing the image-developing
roller, fiction electricity occurs between the image developing roller and toner; toner is
attracted to the image-developing roller.
2. The toner that has been attracted to the image-developing roller is dropped down to
the developing plate to make a thin toner film on the image developing roller side.

4. Transfer
The transfer roller, which is from conductive sponge material, is created to meet intimate
attachment of image drum roller surface and feeding paper. The feeding paper is set up on the
surface of image drum. Plus charge, which is the converse polarity with toner polarity, is applied
from the backside of the paper.
As high plus voltage is applied to transfer roller from the power supply, the plus charge on the
transfer roller surface is induced and transferred to the paper while the paper contact the transfer
roller. The negative charged toner, which has been attracted to the image drum surface, is
transferred to the surface of feeding paper by the plus charge of the backside of the paper.

In the following case, there is a need of cleaning the charged roller, transfer roller, and
cleaning roller.
• Warming up as switching on the power supply
• Warming up after open-close of the cover
• In case of termination of printing operation
• By periodically change the bias voltage that is implied to each roller during continuous
printing, transfer the attached toner from roller to image drum and then return it to
developing device.

6. Fusing
After the termination of transfer the unsettled toner image is settled to paper by heat and pressure
while passing between Heat roller and Back up roller. Heat roller is Teflon coated and is mounted
by heater that can generate heat (Halogen lamp).
The thermistor that contacts the Heat roller adjusts the Heat roller temperature to the temperature
specified by the menu complying with the paper width. For safety the thermostat shuts off the
voltage supply to the Heater by opening the thermostat in the case of abnormally temperature
increasing.
The back up roller is held by the pressure springs on each terminal due to the pressure applied.

2.2 Printing process
The paper fed from Tray 1 and Tray 2 is conveyed by feeding roller, conveying roller, and resist
roller. When feeding paper is from MPT, it is conveyed by MPT, feeding roller, and resist roller.
After that the feeding paper that is conveyed by image drum and the nip part of transfer roller
forms toner image on the paper through electrophotographic process. And then, the toner on the
paper is fused by the heat and pressure as the fuser unit passing through. The paper that fused
the toner image is ejected from the face down stacker of the ejecting roller. In the case of face
up ejecting, it needs to open the backside cover and install face up stacker. (It is unavailable for
duplex printing while it is face up ejecting.)
The above is about the operations at simplex printing, yet the below explains the operations at
duplex printing. While duplex printing, the paper, which firstly passed through the fuser unit after
the backside printing, is conveyed to the inward of Duplex Unit, by the reverse operation of the
second ejecting roller that is a certain time after removing the first ejecting roller of the paper rear
side. Paper, is conveyed by conveying roller of Duplex Unit, and then merges to the same route
with the feeding paper that is from the tray. Onwards, it is the same with the simplex printing
operation by the feeding paper from tray.

Even after the magnet part of the agitating
Bar reaches the highest position, it still
rotates at the same speed by the pressure of
the agitating gear due to the toner resistance.
Sensor plate

Fig 2.3.2
Operation in toner low status
When the magnet part of the agitating bar
reaches the highest position, because
there is no resistance from toner, the
agitating bar drops earlier than the gear
by the gravity itself, and stops by that
status.
For this reason, the time that the magnet
of agitating Bar magnetic attracts the
magnet of sensor plate becomes longer.
The toner low status can be inspected by
monitoring this time.

REPLACEMENT OF PARTS
This section explains the field replacement procedures for parts, assemblies and component
units. While those replacement procedures refer to the disassembling of parts, follow the same
procedures inversely for reassembling them.
The part numbers (1, 2, etc.) employed in this manual are different from those assigned in the
corresponding configuration diagrams of Disassembly for Maintenance (44306601TL) and
RSPL (44306601TR/44306621TR/44306641TR).
4.1 Precautions on the replacement of parts
(1) Prior to replacing a part, be sure to disconnect the AC cord and interface cable.
(a) To disconnect the AC cord, always follow the procedure described below:
Switch the power switch of printer off “O”.
Disconnect the AC insertion plug of the AC power cord from the AC power source.
Disconnect the earth wire from the earth terminal of the AC power source outlet.
Disconnect the AC cord and the interface cable with the printer.
Warning
Risk of Electric Shock
There is a risk of electric shock during replacement of the low voltage power supply.
Use insulating gloves or avoid direct contact with any conducting part of the power supply,
and caution should be exercised during replacement.
The capacitor may take one minute to complete discharge after the AC cord is unplugged.
Also, there is a possibility that the capacitor doesn’t discharge because of a breakage of
the PCB, etc., so remember the possibility of electric shock to avoid electric shock.
(b) To reconnect the printer, always follow the procedure described below:
Connect the AC cord and the interface cable with the printer.
Connect the earth wire to the earth terminal of the AC power source outlet.
Connect the AC power cord insertion plug to the AC power source outlet.
Switch the power switch of printer on “I”.

(2) Do not disassemble the MFP as long as it is operating normally.
(3) Limit disassembly to a necessary minimum. Do not remove other parts than those specified in
the part replacement procedure.
(4) Use the designated maintenance tools.
(5) Conduct disassembly by following the specified sequential order. Failure to observe this order
could damage the parts.
(6) Screws, collars and other small parts should be attached provisionally to their original positions, since they are liable to be lost.
(7) When handling a microprocessor, ROM, RAM and other ICs and circuit boards, do not wear
gloves that tend to generate static electricity.
(8) Printed-circuit boards should not be placed directly on an equipment or floor.

7.5.5.3 Cannot create Certificate
When Certificate cannot be created, the following causes are probable.
Take an appropriate measure by referring to the following items.
* Required input items are not fully entered
Refer to section “7.5.5.3.1 Required input items are not fully entered.”
* The printer is printing.
Refer to section “7.5.5.3.2 The printer is printing.
7.5.5.3.1 Required input items are not fully entered.
Unless all of the required input items are fully entered, Certificate cannot be created.
When creating Certificate, entry into the items of Common Name, Organization, Locality, State/
Province, Country/Region is the must item. (Entry into Organizational Unit can be omitted.)
Solution: Enter the appropriate value into all of the required input items, and execute creation of Certificate.
For more details of the input items, refer to the User’s Manual (Advanced edition).
7.5.5.3.2 The printer is printing.
Certificate cannot be created while printing is in progress. (Print operation has priority).
Solution: Create Certificate when all other operations are complete.
During creation of self-sign certification, during creation of CSR for Certificate of certification authority, and
during installation of Certificate, the printer must not perform any other operations (such as printing) until
the operation is complete (creation of self-sign certification is complete, creation of CSR is complete, and
installation of Certificate is complete).
7.5.5.4 Installation of Certificate is not possible
When installation of Certificate fails, the following causes are probable.
Take an appropriate measure by referring to the following items.
* User has changed the IP address of a printer to other IP address than the “IP address during creation of
CSR”.
Refer to section “7.5.5.4.1 IP address of the printer has been changed”.
* “Network card is initialized” while user is applying issuance of Certification to certification authority (i.e., in
the state of Waiting for Installation of Certificate).
Refer to section “7.5.5.4.2 “Network card is initialized”.
* “Deletion of CSR” was executed while user is applying issuance of Certification to certification authority (i.e.,
in the state of Waiting for Installation of Certificate).
Refer to section “7.5.5.4.3 “Deletion of CSR” is executed”.
* Intermediate Certificate is installed.
Refer to section “7.5.5.4.4 “Installation of intermediate Certificate” is desired”.
7.5.5.4.1 User has changed the IP address of a printer
If IP address of a printer is changed to other IP address than the “IP address during creation of CSR”,
error is issued and installation of Certificate become impossible.
If the changed setup is only the “IP address of printer”, error will not be issued if the IP address is
returned to the original address.
Solution: Return the IP address of printer back to the “IP address during creation of CSR”, and then install
Certificate.
Note! Do not change any setup of printer while creation of Certificate of certification authority is in progress
(during the period starting from creation of CSR up until installation of Certificate). If changed, the already
issued Certificates become invalid necessitating re-setup starting from the very beginning. If printer setup
is changed after Certificate is obtained, the “Security warning” is displayed on the web browser.
If IP address of printer is changed, the Certificate becomes invalid. In the case of Certificate of certification
authority requiring some charge for issuance, another charge may be required for creating Certificate once
again. For details, contact certification authority.).

7.5.4.4.2 “Network card is initialized”
If network card is initialized (to default setup) while creation of Certificate of certification authority is
in progress (during the period starting from creation of CSR up until installation of Certificate), the
setup information of the Certificate is deleted. If information is deleted once, the information cannot be
recovered by any means. (Even when the same information as before is entered, the same Certificate
cannot be created.) .
Solution: Repeat all the steps from the very beginning. (Certificate under application is already invalid.)
7.5.5.4.3 “CSR is deleted”
If network card is initialized (to default setup) while creation of Certificate of certification authority is
in progress (during the period starting from creation of CSR up until installation of Certificate), the
setup information of the Certificate is deleted. If information is deleted once, the information cannot be
recovered by any means. (Even when the same information as before is entered, the same Certificate
cannot be created.) .If information is deleted once, the information cannot be recovered by any means.
(Even when the same information as before is entered, the same Certificate cannot be created.) .
Solution: Repeat all the steps from the very beginning. (Certificate under application is already invalid.).
7.5.5.4.4 “Installation of intermediate Certificate” is desired
Some certification authorities use the procedure of installing the SSL server Certificate (printer
Certificate) and the intermediate Certificate into printer as the same time.
However, printer of this model supports installation of only a single Certificate, intermediate Certificate
cannot be installed in printer. Be sure to install the SSL server Certificate in printer.
When installation of intermediate Certificate is required, install the intermediate Certificate not in
printer, but in client PC (browser).
For the method of installing the intermediate Certificate in client PC (browser), refer to the following.
Installing the intermediate Certificate (or CA certificate) in client PC (browser)
[Procedure]
1. Double-click the intermediate Certificate (or CA certificate) that is issued by certification authority, on a client
PC to display the intermediate Certificate (or CA certificate).
Example: For an example, the intermediate Certificate of Comodo has the text (PEM) format:
ComodoJapanCA.Crt, and the binary format: ComodoJapanCA.cer. Either one of these formats can be
opened. (Same result can be obtained.)
Open either ComodoJapanCA.crt or ComodoJapanCA.cer.

Description for Operation of Second Tray unit
Second Tray unit receives a signal from the printer main body and feeds paper to the printer main body.
Paper Feed from the Second Tray unit (Tray2)
1. When a signal is received from the printer main body, the pulse motor is rotated (in a clockwise
direction), and by setting the paper feed clutch to ON, the paper feed roller and pick-up roller are
rotated. Therefore, paper in a tray is fed.
2. After paper is carried by the transfer roller (Tray 2) and transfer roller (main body) to set the entrance
sensor lever to ON, the paper goes into the regist roller, and a certain volume of paper is carried. (the
skew is adjusted due to this operation.)
3. By setting the regist clutch to ON, the paper is carried by the regist roller.
