CHAPTER 2 EXPLANATION OF OPERATION

I. 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.

CHAPTER 2 EXPLANATION OF OPERATION

4. 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.

CHAPTER 2 EXPLANATION OF OPERATION

8. 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.

CHAPTER 2 EXPLANATION OF OPERATION

II. 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 directed 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.

CHAPTER 2 EXPLANATION OF OPERATION

(1) Paper fed from 1st Tray

1. As illustrated in Figure 2-1, when the solenoid is ON, the register motor rotates
(Counterclockwise turn), transporting the paper until the IN1 sensor comes ON. (When the
solenoid is ON, the paper feed roller is driven.)

2. After causing the IN1 sensor to come ON, the paper is further carried over a certain distance
to finally hit register roller L. (This corrects skew of the paper.)

3. As shown in Figure 2-2, the solenoid is turned OFF and the paper is transported by register
roller L. (When the solenoid is OFF, register roller L is driven.)

(4) Up/down-motions of ID units

1. The up/down-motions of the ID units take place driven by the lift-up motor.

2. Figure 2-6 shows the motions of the different ID units when the printer is operated for color
print. As the lift-up motor rotates (Clockwise turn), the lift-up link slides to the left, causing
the ID units to come down, as can be seen in Figure 2-6. Namely, the printer is readied for
color print.

3. Figure 2-7 shows the motions of the different ID units when the printer is operated for
monochrome print. As the lift-up motor rotates (Counterclockwise turn), the lift-up link slides
to the right, causing the ID units to go up, except for the K-ID unit, as can be seen in Figure

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 (page 4-21)
to check the error indication.

CHAPTER 2 EXPLANATION OF OPERATION

Error checking methods and remedial methods
The color drift correction test function among the other self-diagnostic functions is employed to

check errors. (page 4-21)

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.

2-12

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 (page 4-22) 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.

CHAPTER 2 EXPLANATION OF OPERATION

Shutter

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: 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.

Belt counter: 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.

Fuser counter: 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
rounded up)
