6) Select the number that corresponds to the adjustment item SPF

(SUB) using the numeric keypad.

This adjustment items is intended to adjust the image magnifica-
tion in the sub-scanning direction in SPF mode.

7) Press the Start key

8) Adjust the image magnification factor by entering an appropriate

value through the numeric keypad.

9) Press the P or Start key

Pressing the Start key starts copy operation as well as applying the
adjustment value.

Repeat the above adjustments until an acceptable result is obtained.

Note: After adjusting the image magnification in the sub-scanning

direction through Simulation 48-1, do the following steps if mak-
ing a copy at a different magnification factor fails to produce a
correctly scaled copy.

1) Go through the modes specified in Simulation 48-5.

2) Using the numeric keypad, select the number that corresponds to

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. 

• The scanner (reading) unit has been replaced.

• The LSU has been replaced.

• U2 trouble has occurred.
