Chapter 3 Maintenance & Disassembly
Drum Counter
The drum counter is NOT an actual count of the pages printed by an image drum. The count is a
combination of the main motor revolution time and the number of printed sheets. Thus, the type
of
printing being performed becomes a factor in determining drum life. If the printer performs many
single page print jobs, the drum ages more quickly than if the printer performs many multiple page
print jobs.
The image drum has an estimated lifespan of 14,500 to 15,000 pages at 100 pages per job. The
lifespan is 11,500 to 12,000 pages at three pages per job. These figures will vary!
The drum counter should be reset when a new image drum is installed.
Refer to Sections 3.2 Disassembly and 3.4 Cleaning when installing the image drum ().
The drum counter may be accessed from both the Administration Mode and the Service Mode.
The drum counter in the Administration Mode allows the end user to reset the drum counter when
replacing an image drum.
The drum counter in the Service Mode allows the service technician to view the drum count and/or
reset the drum counter.
