Sub item
MEMO:
At times, the indicated value for the fogging items may differ before and after input (maximum of +/-3). The fact has to do with the way indicated values
are computed, and will not affect the operation of the machine.
TR-N1 Use it to enter the output adjustment value of the transfer charging current. (simplex mode, plain paper; or 1st side of double-sided
print)
range: -650 to 0 (uA) [Default: -590 uA]
- 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.
TR-N2 Use it to enter the output adjustment value of the transfer charging current. (plain paper, 2nd side of double-sided print)
range: -650 to 0 (uA) [Default: -590 uA]
- 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.
PRE-TR Use it to enter the output adjustment value of the pre-transfer charging current.
range: 0 to 300 (uA) [Default: 165 uA]
- 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. When lowering the value for
adjusting the degree of foggy, the degree of toner scattering image increases. Select COPIER > OPTION > BODY > ACFRQNY/
ACFRQ-R/ACFRQ-T to adjust the degree of foggy.
HVT-TR Use it to enter the offset value of the transfer high-voltage output for the high-voltage unit.
range: -100 to 100
- 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.
H-PRE-TR Use it to enter the offset voltage of the pre-transfer output for the high-voltage unit.
range: -100 to 100
- 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.
