This adjustment is needed in the following situations:
* When the LSU (writing) unit is replaced.
* U2 trouble has occurred.
* The PCU PWB has been replaced.
* The EEPROM of the PCU PWB has been replaced.
* When the color shift occurs.

* When the LSU (writing) unit is replaced.
* U2 trouble has occurred.
* The PCU PWB has been replaced.
* The EEPROM of the PCU PWB has been replaced.
* When the color shift occurs.
1)
Go through the modes specified in Simulation 50-10.
2)
Set A4 (11" x 8.5") paper in the paper feed tray.
3)
Select the paper feed tray set in procedure 2) with the scroll
key.
key.
4)
Press [EXECUTE] key.
The check pattern is printed out.
The check pattern is printed out.
5)
Check that the inside dimension of the printed half tone is 240

±0.5mm.
If the above requirement is not met, do the following steps.
6)
Change the set value of set item A.
When the set value is changed by 1, the dimension is changed
by 0.1mm.
When the set value is increased, the BK image magnification
ratio in the main scanning direction is increased. When the set
value is decreased, the BK image magnification ratio in the
main scanning direction is decreased.
When the set value is changed by 1, the dimension is changed
by 0.1mm.
When the set value is increased, the BK image magnification
ratio in the main scanning direction is increased. When the set
value is decreased, the BK image magnification ratio in the
main scanning direction is decreased.
Repeat procedures 2) - 6) until a satisfactory result is obtained.
