MX-M264U ADJUSTMENTS AND SETTINGS 5 – 5
2)
Select an output mode and an item to be adjusted.
3)
Enter the developing bias values of items A/B under TS_OFF/
ON.
When [EXECUTE] key is pressed, the voltage entered in the
procedure 3) is outputted for 30sec and the set value is saved.
When [EXECUTE] key is pressed again, the output is stopped.
CAUTION: Note that the adjustment value may differ depending on
the MC/DV high voltage power PWB.
Since the adjustment value label is attached on the MC/
DV high voltage PWB, the PWB must be removed in
order to check the adjustment value.
This is a troublesome procedure. Therefore, it is advis-
able to put down the adjustment value in advance.
When the adjustment value (specified value) of the mid-
dle speed mode is set, the adjustment values of the
other modes are automatically set according to the mid-
dle speed mode setting in a certain relationship.
CAUTION: Since the high voltage output cannot be checked with a
digital multi meter in this model, a judgment of the out-
put must be made by checking the print image quality.
2-C
Transfer current and voltage adjustment
This adjustment must be performed in the following cases:
* When the TC high voltage PWB is replaced.
* U2 trouble has occurred.
* The PCU PWB has been replaced.
* The EEPROM of the PCU PWB has been replaced.
