a. Fusing unit drive
To drive the fusing unit, drive power is transmitted from the drive
motor (FUSM) through the connection gear to the upper heat roller
gear.
The drive motor (stepping motor) is driven by the motor drive IC in
the driver PWB according to the control signal sent from the PCU.

b. Heater lamp drive
The surface temperature detected by the thermistor is sent to the
PCU. When the temperature is lower than the specified level, the
PCU sends the heater lamp lighting signal to the heater lamp drive
circuit in the DC power PWB.
The triac in the heater lamp drive circuit is turned on to apply AC
power to the heater lamp, which turns on to heat the heat rollers.
The thermostats are provided as a safety measure to prevent
against an abnormally high temperature of the heat rollers.
When the thermostat is opened, the power supply (AC neutral) to
the heater lamp is cut off.

AR-C262M DESCRIPTIONS OF EACH SECTION 7 - 2
The upper and the lower heat rollers are provided to heat from
above and below. This is because it is necessary to heat four layers of toner from above and below and right and left to fuse it on
paper.
The upper and lower heat rollers are of silicon rubber. This is
because of the following reasons:
1) To provide a greater nip quantity and a higher heating capacity
for paper.
2) The soft, flexible rollers press multi-layer toner without deformation to fuse on paper.
3) An even pressure is applied to an uneven surface of multilayer toner.
d. Fusing temperature control
The temperature sensor is provided at the center of the upper and
the lower heat rollers.
The temperature sensor at the center detects the heat roller temperature and controls the heater lamp to keep the fusing temperature at the specified level.
The fusing temperature is switched according to the machine condition and paper type selected.

a. Transfer belt drive
The transfer belt drive power is transmitted from the drive motor
(BTM) to the transfer drive roller.
The motor (stepping motor) is driven by the drive signal sent from
the PCU.
b. Applying a transfer high voltage to the transfer roller
According to the high voltage control signal from the PCU, the signal is converted into a transfer high voltage control signal with the
HV (MC) PWB, and sent to the HV (TC) PWB.
According to each color transfer high voltage control signal, a high
voltage is applied to each transfer roller from the transfer high voltage
HV (TC) PWB through the connection spring to each transfer roller.
e. Transfer belt unit up and down
In color print, the transfer belt is in contact with four OPC drums. In
black and white print, the transfer belt unit moves down so that
only the black OPC drum is in contact with the transfer belt.
This up-and-down movement of the transfer belt is performed by
the lift-up motor (BLUM), the lift-up cam, and the unit position sensor (BLUD).
When the left cabinet is opened for jam process, the rotating
mechanism of the lift-up unit separates all four OPC drums from
the transfer belt.
• Transfer belt position for color print
The four OPC drums are in contact with the transfer belt by rotation of the cam in the transfer lift-up unit.

c. Process control sensor control
The process control shutter is provided on the process control
sensor of monochrome (PCSK) and color (PCSC). When the shutter is open (in image density correction and automatic registration), the toner patch formed on the transfer belt is read by the
process control sensor, and its information is sent to the PCU.
When the shutter is closed, the calibration sheet is read to perform
calibration of the sensor itself.
The shutter operation is controlled by the calibration solenoid
(CALS).
d. Belt waste toner full detection
Toner scraped by the belt cleaning blade is transported to the
waste toner box by the belt waste toner transport shaft.
When the waste toner box is full, the rotation load of the waste
toner transport shaft increases to turn on the waste toner full
detection switch with the lever by the torque limiter function.

b. LED (writing) unit
Four LED (writing) units are provided for each of Yellow, Magenta,
Cyan, and Black.
Each LED (writing) unit converts YMCK dot image data outputted
from the ICU PWB into LED light, and radiate the light onto the
OPC drum, forming electrostatic latent images on the OPC drum.
Since the position of each LED unit of CMYK is shifted in the
paper transport direction, the above operation depends on the relative position and differs in the operating timing.

When LED light is radiated onto the OPC drum CGL, positive
and negative charges are generated. Positive charges generated in the CGL are attracted and moved by negative charges
of the OPC drum, and negative charges by positive charges of
the aluminum layer of the OPC drum. Therefore, on the OPC
drum surface and in the aluminum layer, positive and negative
charges are neutralized, reducing the OPC drum surface
potential.
Electric charges remain in the areas where LED light is not
radiated onto the OPC drum.
As a result, electrostatic latent images are formed on the OPC
drum surface.
Charges are disposed in direct proportion to the amount of
light received.
Removed residual toner is transported to the waste toner section of the toner cartridge by the waste toner transport screw.

moved by negative charges of the OPC drum, and negative
charges by positive charges of the aluminum layer of the OPC
drum. Therefore, on the OPC drum surface and in the aluminum layer, positive and negative charges are neutralized,
reducing the OPC drum surface potential, preparing the drum
surface for the new copy cycle.

Toner in the developing unit is agitated by the mixing roller.
By mixing operation, toner is negatively charged due to mechani-
cal friction.
The developing bias voltage (negative) is applied to the develop-
ing roller.
The diflerence for the voltage potential between the toner and DV
roller surface attracts the toner to the DV roller.
In the areas of the OPC drum, when the charge was detected, the
voltage potential difference is greater than the DV roller. Therefore
the toner is attracted from the DV roller to the drum.
In the unexposed areas of the drum, the potential on the DV roller
created by the bias voltage and therefore the toner to not attracted
to those areas of the drum.
Negatively charged toner is attracted and attached to the exposed
area on the OPC drum surface where the negative potential was
reduced by LED exposure.
On the other hand, in the areas on the OPC drum where exposure
was not made, the positive potential is higher than the developing
bias voltage, repelling toner.

c. Image scan/color separation
The CCD element, appeared as one unit, but has three separate
rows of CCD elements drive each for (RGB).
Light is radiated to a document by the copy lamp (Xenon lamp),
and the brightness of the reflected light is received by the three
line (RGB) CCD element and converted into (analog) image signals.
Each color component of RGB is separately extracted from the
document image by the three lines (RGB) of the CCD elements.
The red CCD extracts the red components from the document
image, the green CCD the green components, and the blue CCD
the blue components. This operation is called Color Separation.
The CCD element, appeared as one unit, but has three separate
rows of CCD elements drive each for (RGB).
Scanning of a document in the main scanning direction is performed by the CCD elements. Scanning of a document in the sub
scanning direction is performed by shifting the scanner unit position with the scanner motor.
Document images are optically reduced by the lens and projected
to the CCD elements.
The scanning resolution is 600dpi

Reverse solenoid
When original is detected in the original tray, EMPS turns ON (no-output level).
Original size is determined by DWVR, DLS1 and DLS2.
Two operation modes, single-side and duplex, are available.
For single-side, after the print SW is turned ON, DFM rotates in the forward direction and the original is transported. (DTM and DEM forward
rotation begins.)
REGS detects the leading edge of the fed original (REGS output level HIGH); the original contacts the resist rollers and stops.
The DFM reverses its rotation direction , the resist rollers rotate, and the document is transported.
The TIMS detects the leading edge of the original, and the DFM turns OFF.
After the DTM and DEM stop, the DTM rotates forward, and the transport belt moves. Or, the DFM reverses its direction of rotation, and the
original is sent to the transport section.
When the TIMS detects the trailing edge of the original, the DFM stops, after which the DTM (transport belt) also stops. After scanning is
completed, the DTM and DEM turn ON, and the original is discharged. After the DES detects the trailing edge of the original, the DTM and
DEM turn OFF (stop).
