1. Parts Replacement

If replaced, some parts of the machine calls for adjustment or counter initialization using service mode.

Be sure to perform the tasks indicated below whenever you have replaced these parts.

　

■DC Controller PCB

When replacing the DC controller PCB, remove the DIMM ROM [1] from the detached DC controller PCB, and mount it on the new DC controller PCB.

■Heat discharge fan filter

If you have replaced the fan filter, you will have to reset the fan filter life counter so that the count will start anew.

Make the following selections in service mode to reset the counter:

　COPIER > COUNTER > DRBL-1 > OZ-FIL-1

Each life count is kept in memory on the DC controller PCB. If you have to replace the DC controller PCB, be sure to enter the count that has been read of the previous PCB.

2. Maintenance Servicing

The following must be replaced, cleaned, or checked on a periodical basis by the service person.

Be sure to perform the appropriate work at the indicated intervals.

　

Item	Parts name	Work	Interval	Description
