AR-651/810  PREVENTIVE MAINTENANCE

The timing for the parts replacement usually depends on the number of printouts ever made after they were

replaced before. However, the life span of them changes depending on the general use of users and the

environment in which the machine is placed. Therefore, it is necessary to consider not only the number of

printouts but also the driving time when deciding the timing for the parts replacement in order to utilize the

parts and materials effectively.

This copier packs the PM support mode, which makes it possible to see the general use of each part (the

number of printouts, driving time) and replacement record and to do a counter clearing operation more

efficiently when replacing.

The replacement record can be printed out in the list printing mode (9S-103).

(1) Operational flow

* The screen goes back to the main screen when the counter clear is executed or the [CANCEL] key is pressed after
