This chapter explains how to replace the toner and image drum cartridges,
and clean the LED array.
General Consumables Information
The Toner Cartridge: Type 7 (P/N 40468801)
Toner Cartridge Life
Toner cartridge life depends on the page density, the percentage of each
page that is printed black. An average business letter is printed at between
3% and 5% density, graphics density is usually higher. The higher the print
density, the more toner is used.
On the average, a toner cartridge will produce approximately 5000 sheets at
5% print density.
Important: The first toner cartridge you place in your printer will only
produce between 2500 and 3500 sheets. This is normal, as
the new image drum reservoir and developing roller system
must saturate with toner.
Chapter 8: Maintenance
The Image Drum: Type 7 (P/N 40468701)
Image Drum Life
The life of the image drum depends on a number of factors, including the
operating temperature, humidity, the type of paper you use, and the number
of pages per job. Each time you print or turn the printer on, the drum has to
rotate to start up and to wind down. As a result, frequent one-page print jobs
will wear down your drum more quickly than multiple-page print jobs.
The image drum cartridge should last up to 30,000 pages at 3 pages per job
(continuous printing) or 19,000 pages at 3 pages per minute.
