1. SERVICE REMARKS

1.12 RDH
1. Take care not to damage the harnesses of the original table by pulling
roughly when you remove the original table.
2. Take care not to injure yourself by dropping the RDH unit when removing
it.
3. After replacing the RDH main PCB or RDH RAM board, perform the RDH
motor adjustment, RDH registration adjustment, and CFF registration
adjustment. (This allows the RDH to communicate with the copier main
PCB.)
1.13 FINISHER
1. Do not turn on the main switch while the shift tray is not installed. Both
the stack height sensor and the shift tray upper limit switch do not work
without the shift tray, and causes the tray lift mechanism broken.
2. Before removing the timing belts, mark the position of the tension
brackets.
