Reference:
Timing of Cleaning
[1] the surface temperature of the fixing roller is 100 deg C or lower when the control panel power switch is turned on
[2] when wire cleaning is executed in user mode
[3] at the end of LSTR after making 2000 prints since previous wire cleaning

SERVICE MODE:
- COPIER> ADJUST> HV-TR> TR-N1 (output adjustment for plain paper simplexing or for 1st side of duplexing)
If the DC controller PCB has been replaced or the RAM on the DC controller PCB has been initialized, enter the value indicated on the service label.
-
COPIER> ADJUST> HV-TR> TR-N2 (output adjustment for 2nd side of plain paper duplexing)
If the DC controller PCB has been replaced or the RAM to the DC controller PCB has been initialized, enter the value indicated on the service label.
ERROR CODE:
- E069 (transfer charging output error)
The presence of over-current (TRERR=1) is detected, as caused by leakage.
