PREVENTI VE 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 / develop counts 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. In addition, the drum rotates 4 times at color modes to transfer the images of 4 colors on the transfer belt, overlaying one after another. Therefore, the number of output pages is counted as “4” for 1 page for printing at color mode. This equipment has the PM support mode, which makes it possible to see the general use of each part (the number of output pages, develop counts and drive counts) 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). 4.1. 2 Operational f low a nd operational scr een [ 1 ] Oper at iona l flow Fig.4-1 PM support mode activated [6]+[START]+[POWER]ON Main screen Main unit list displayed Sub screen Sub unit list displayed Clear screen Counter clear confirmation displayed Counter clear performed [RETURN] pressed [CANCEL] pressed [RETURN] pressed [CANCEL] pressed [INITIALIZE] pressed Clear finished Clear finished [2] Main unit chosen [SUB UNIT] pressed Main unit chosen [RESET] [START] Sub unit chosen [RESET] pressed
