the mode for which to make adjustments.

2) Press the Start key

3) Enter the copy adjustment value using the numeric keypad.

Make adjustments by changing the adjustment value for high revo-
lution mode if the copy magnification is not correct for microcopies;
or the adjustment value for low revolution mode if the copy magnifi-
cation is not correct for blowbacks.

4) Press the Start key

This applies the adjustment value.

This adjustment is needed in the following situations:

• The paper feed section has been disassembled.

• The MFP control PWB has been replaced.

• The EEPROM on the MFP control PWB has been replaced.

• The scan control PWB has been replaced.

• The EEPROM on the scan control PWB has been replaced.

• The scanner (reading) section has been disassembled.

2) Enter the number that corresponds to the paper feed tray that

needs adjustments.  (Choose from numbers 10 to 16.)

3) Press the Start key

4) Press the Start key

A self-print pattern image is printed. 

Check the off-center of the printed self-print pattern image. 

If so, no adjustment is required.

If the above requirement is not met, do the following steps. 

5) Using the numeric keypad, change the adjustment value in steps

of 0.1 mm. A larger setting shifts the printed image toward the front
side.  

6) Press the P or Start key.  Pressing the Start key starts print opera-

tion as well as applying the adjustment value. 

Check the off-center of the printed self-print pattern image. 

Repeat steps 5 to 6 until an acceptable result is obtained. 

This adjustment is needed in the following situations: 

• The MFP control PWB has been replaced.

• The EEPROM on the MFP control PWB has been replaced.

• The scan control PWB has been replaced.

• The EEPROM on the scan control PWB has been replaced.

• The scanner (reading) section has been disassembled. 

• The scanner (reading) unit has been replaced. 

• U2 trouble has occurred.

1) Go through the modes specified in Simulation 50-12.

2) Using the numeric keypad, select the adjustment item PLATEN,

which is intended to adjust the off-center in original table mode. 

3) Press the Start key

Measure the void area dimensions in the front and rear frame
directions, and make sure that the difference between the two
dimensions is within ±1.5 mm.

Select 2, and 
press [START] key.
