MX-M700N ADJUSTMENTS 6 – 5
Transfer voltage adjustment (transfer roller cleaning/transfer
roller print modes)
This adjustment is needed in the following situations:
* The high voltage power PWB (TC cleaning) has been replaced.
* U2 trouble has occurred.
* The PCU PWB has been replaced.
* The EEPROM of the PCU PWB has been replaced.
1)
Connect the transfer section to the main body side using the
transfer extension harness (DHAi-3629FCZZ).
2)
Remove the front frame cover of the duplex section, and
remove the rear frame cover of the transfer section.
3)
Apply a digital multi-meter to the check pin of the high voltage
PWB (TC cleaning) and the chassis GND.
4)
Go through the modes specified in Simulation 8-18.
5)
Select the number that corresponds to the adjustment item
(CRHV PLUS / CRHV MINUS) using the numeric keypad.
6)
Press the Start key.
7)
Press the Start key to have the voltage output for 30 seconds.
The operation can be stopped with the SYSTEM SETTINGS
key.
If the output voltage is not within the requirement, do the fol-
lowing steps.
8)
Enter the adjustment value using the numeric keypad.
9)
Press the Start key.
(The adjustment value is put into memory, and the correspond-
ing voltage is output for 30 seconds.)
Repeat steps 8 to 9 until the output requirement is satisfied.
