Keep the following three points in mind when replacing the PCBs:
• Be sure to transfer the six EEP-ROMs from the old to new PCBs; at
that time, be sure to refer to the color of each round label attached to the
EEP-ROM for correct transfer.
• Be sure to enter the values indicated on the label [3] on the new PCB in
service mode by making the following selections:
COPIER>ADJUST>HV-TR>D-PRE-TR
COPIER>ADJUST>HV-TR>D-HV-TR
COPIER>ADJUST>HV-SP>D-HV-SP
COPIER>ADJUST>DEVELOP>D-HV-DE
• Be sure to transfer the shorting connector [4] of J303 on the PCB from
the old to new PCB. (Keep in mind that failure to do so will disable the
control panel indication.)
