MEMO:
At times, the value indicated for the following items may differ before and after input (maximum of +/-3). The fact has to do with how the indication values
are computed, and will not affect the operation of the machine.
Sub item
DE-NO-DC Use it to enter the developing DC bias output value for when no image is being formed.
range: 0 to 600 (V)
Do not use with the normal service.
MEMO:
The item is enabled only when PO-CNT is '0' (COPIER > OPTION > BODY > PO-CNT).
HVT-DE Use it to enter the offset value for the developing high-voltage output of the high-voltage unit.
range: -50 to 50
- Be sure to enter the value indicated on the label attached to the new unit if you have replace the high-voltage unit.
- Be sure to enter the value indicated on the service label if you have replaced the DC controller PCB or initialized the RAM.
- Use the item only when performing the foregoing operation. Do not use with the normal service.
D-HV-DE Use it to enter the offset value for the developing high-voltage of the DC controller PCB.
range: -100 to 100
- Be sure to enter the value indicated on the label attached to the new PCB if you have replaced the DC controller PCB.
- Be sure to enter the value indicated on the service label if you have initialized the RAM on the DC controller PCB.
- Use the item only when performing the foregoing operation. Do not use with the normal service.
OFFSETDA Use it to enter the high-voltage D/A output offset value for the developing AC bias.
range: -100 to 100
- Be sure to enter the value indicated on the label attached to the new PCB if you have replaced the DC controller PCB.
- Be sure to enter the value indicated on the service label if you have initialized the RAM on the DC controller PCB.
- Use the item only when performing the foregoing operation. Do not use with the normal service.
OFFSETAC Use it to adjust the offset value of the developing AC bias.
range: -120 to 120
- Be sure to enter the value indicated on the label attached to the new unit if you have replace the high-voltage unit.
- Be sure to enter the value indicated on the service label if you have replaced the DC controller PCB or initialized the RAM.
- Use the item only when performing the foregoing operation. Do not use with the normal service.
