c. Fusing operation

Color toner of YMCK on paper is heated and pressed by the heat rollers to be fused on paper.

At that time, color toner of YMCK is mixed to reproduce nearly actual colors of document images.

Driver PWB

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-C260/C260M 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 multi-layer 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.

(4) Operational descriptions

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.

YMC

• Transfer belt position for black print Only the black OPC drum is 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.

(4) Operational descriptions

a. Drum cartridge and toner cartridge drive

The drive power for the drum cartridges are transmitted from the drive motor (DM) to the drum gears.

The toner cartridge is driven through the drum gear and the connection gear.

The motor (stepping motor) for black is driven by the drive signal sent directly from the PCU, and the motors color are driven by the drive signals sent from the PCU through the driver PWB.

AR-C260/C260M DESCRIPTIONS OF EACH SECTION 7 - 16

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.

Removed residual toner is transported to the waste toner section of the toner cartridge by the waste toner transport screw.

4) The whole surface of the OPC drum is discharged.

The screen grid is attached to the main charger unit. The OPC drum is charged at a voltage nearly same as the voltage applied to the screen grid.

2) LED light is radiated onto the OPC drum surface by the LED (writing) unit to form electrostatic latent images.

LED light

OPC drum

CTL CGL Aluminum

layer

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.

Lens

CTL CGL

Aluminum layer

By radiating discharge lamp light onto the discharge lens, light is radiated through the discharge lens to the OPC drum surface.

When discharge lamp 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, preparing the drum surface for the new copy cycle.

<1> Remaining toner quantity detection

Rotation of the detection lever connected to the mixing roller is sensed by the sensor (TES) to detect the remaining toner quantity.

Toner in the developing unit is agitated by the mixing roller.

By mixing operation, toner is negatively charged due to mechanical friction.

The developing bias voltage (negative) is applied to the developing 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.

<2> Waste toner collection

Waste toner collected by the drum cleaning blade is transported to the waste toner box of the toner cartridge by the toner transport spring in the drum unit.

ADJ 2 Image density sensor adjustment

The image density sensor sections are of uneven quality in parts and assembly. This causes variations in the absolute detection level between machines. This adjustment (calibration) is performed to correct the variations.

This adjustment is required in the following cases:

• When the image density sensor is replaced.

• When the transfer unit is replaced.

• When maintenance is performed.

• When U2 trouble occurs.

• When the PCU PWB is replaced.

• When the EEPROM on the PCU PWB is repalced.

AR-C260/C260M SETTING AND ADJUSTMENTS 8 - 4

The targets of the adjustment are the color image density sensor and the black image density sensor. There are following adjustment methods:

• Color image density sensor adjustment (adjustment by the adjustment jig) SIM44-13

• Black image sensity sensor adjustment SIM44-2

• Image density sensor adjustment (The color image density sensor and the black image density sensor are adjusted at the same time.) (Simple adjustment) SIM44-36

Normally the following adjustments are executed:

• ADJ 2A Color image density sensor adjustment (adjustment by the adjustment jig) (SIM44-13)

• ADJ 2B Black image density sensor adjustment (SIM44-2)

Note:

There are two methods to adjust the color image density sensor; one method uses the adjustment jig, and the other method does not use it.

If there is no adjustment jig available, the simple adjustment (SIM44-

36) can be made, which may, however, result in insufficient adjustment accuracy depending on the machine condition.

If toner, the OPC drum, and the transfer belt are not new ones or almost new ones, the simple adjustment is not recommended.

Even though the machine conditions are well, the adjustment by use of the adjustmment jig gives a higher adjustment accuracy than the adjustment without the adjustment jig (simple adjustment).

Also note that SIM44-36 must not executed unnecessarily after execution of the color image density sensor adjustment (adjustment by the adjustment jig) with SIM44-13.

If SIM 44-36 is executed, the contents of the color image density sensor adjustment (adjustment by the adjustment jig) with SIM44-13 are erased, and the adjustment result of SIM44-36 is saved.

When the color image density sensor is adjusted with SIM44-13 and the black image density sensor is adjsuted with SIM 44-2, the adjustment with SIM44-36 is not required.

To adjust the black image density sensor, the adjustment jig is not required.

Before executing this adjustment, check the following items:

• Check that the color imagte density sensor is clean.

• Check that the image density sensor calibration plate is clean.

• Check that the transfer belt is free from scratches.

When the image pattern on the front frame side is skewed to the right (arrow direction A) with the rear frame side as the reference, turn the adjustment screw clockwise. When the image pattern is skewed to the left (arrow direction B), turn the adjustment screw counterclockwise.

When the adjustment screw is turned 1/4 rotation, the image position is shifted by one dot.

Remark: The print engine image focus adjustment is performed by

changing the distance between the LED array unit and the OPC drum.

The print engine image skew adjustment is performed by changing the parallelism of the LED array unit for the OPC drum.

If either of the two adjustments is performed, it may affect the other adjustment due to the machine structure.

After completion of the above procedures, check that both of the above two adjustments are satisfied.

ADJ 4 Image registration adjustment

There are two methods of the image registration adjustment: the manual adjustment and the automatic adjustment. Either of them uses the simulation.

This adjustment is required in the following cases:

• When the scanner (writing) unit is replaced.

• When the scanner (writing) unit is removed from the machine.

• When color image mis-resist is generated in the main scanning

direction.

• When color image mis-resist is generated in the sub scanning direc-

tion.

• When installation or the installing place is changed.

• When maintenance is performed. (When the OPC drum, the photo-

conductor cartridge, the transfer unit, or the transfer belt is replaced.)

• When U2 trouble occurs.

• When ICU PWB is replaced.

• When EEPROM on ICU PWB is replaced.

Remark: Though SIM 50-22 is not performed under the following con-

ditions, the image registration adjustment is performed automatically.

∗ When the toner cartridge is replaced. ∗ At every 8,000 copies (total of print quantity and copy quantity)

(When 8,000 copies is reached during a job, the machine stops after completion of the job.)

If the set item AR of SIM 44-1 is set to OFF (Disable), the above operation is not performed.

After setting the image registration to the best by SIM 50-20, when the image registration adjustment is automatically performed, the bestadjusted condition may be varied. To avoid this, set the item AR of SIM 44-1 to OFF (Disable).

Note:

Before executing this adjustment, check that the following adjustments have been properly completed.

∗ Print engine image focus adjustment (Scanner (writing) unit) ∗ Print engine image skew adjustment (Scanner (writing) unit) ∗ Image registration sensor adjustment

(1) How to read the fine adjustment pattern

The highest-density area of the color is regarded as the center and as the reading value of the shift amount. (The reading value in the figure below is 4.)

(2) How to read the rough adjustment pattern

Judge the polarity by checking that the color line is shifted to the positive or the negative side.

The scales are made with the black line at the center as 0, the first mark as 20, the second mark as 40, and the third mark as 60.

The interval between rough adjustment marks is 20. (For an example shown in the figure below, it is between 20 and 40 on the positive side. Therefore, the reading value is 20.)
