4. PREVENTIVE MAINTENANCE (PM)
4. 1. PM Support Mode
4. 1. 1. General description
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).
