MX-3114N ADJUSTMENTS AND SETTINGS 5 – 7
2-B
Adjust the developing bias voltage
This adjustment must be performed in the following cases:
* When the MC/DV high voltage power PWB is replaced.
* U2 trouble has occurred.
* The PCU PWB has been replaced.
* The EEPROM of the PCU PWB has been replaced.
1)
Enter the SIM 8-1 mode.
2)
Select an output mode and an item to be adjusted.
3)
Enter the adjustment value (specified value) in the middle
speed mode, and press [OK] key.
Enter the adjustment value of each mode which is specified on
the label attached on the MC/DV high voltage power PWB.
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.
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 advisable to put
down the adjustment value in advance.
When the adjustment value (specified value) of the middle speed
mode is set, the adjustment values of the other modes are auto-
matically set according to the middle speed mode setting in a cer-
tain relationship.
Since the high voltage output cannot be checked with a digital multi
meter in this model, a judgment of the output must be made by
checking the print image quality.
