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 output pages ever printed 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 equipment is placed. Therefore, it is necessary to consider not
only the number of output pages but also the drive counts when deciding the timing for the parts
replacement in order to utilize the parts and materials effectively.
This equipment has the PM support mode, which makes it possible to see the general use of each part
(the number of output pages, drive counts) and replacement record and to do a counter clearing opera-
tion more efficiently when replacing.
The replacement record can be printed out in the list printing mode (9S-103).
