5055-xxx Viewing and resetting the drum counters The drum counters increment when a page is printed. The drum counter for a particular plane increments (if that color is printed), by 1 for Letter, A4, A5, B5 and envelopes, and by 1.2 for Legal and B4. It increments by 2 for 11 x 17, 12 x 18 (C912 only), and A3. The counters are used to track printer usage. The current value of the drum counter may be viewed in the Diagnostic menus by selecting the Drum Count menu, but this value is not viewable from the Ready menu. The following screen illustrates the operator panel when the cyan drum counter displays. The leftmost digit ('1' in this example) blinks, indicating it is the first digit to be changed. To change the value, press Menu until the desired value display. Press Select to move to the next digit. The next digit ('2' in this example) blinks. Continue modifying each digit using this method. To skip a digit (and keep its current value), press Select. After the final digit (5 in this example), press Select and the new page count is stored in NVRAM. Cyan Drum Count =12345 The drum counts can be reset by scrolling to the appropriate drum color and pressing Select. 3-28 Service Manual
