Maintenance Items
Routine maintenance items are parts or assemblies that require periodic replacement. These items are
typically customer replaceable (CRU).
The listed items have limited life and require periodic replacement.
Print life is based on “typical” office printing and 5% coverage per color on 24 lb. paper. Print life
figures are not guaranteed and varies depending on usage habits. Imaging Unit print life is based on 3-
page jobs using letter-size paper. Less than 3 page average run length has an adverse effect on yield.
Consumables
Consumables consist of a Toner Cartridge and a Drum Cartridge. The machine ships with a starter
toner and drum cartridge.
The system has a CRUM (Customer Replaceable Unit Monitor) to record regional and toner usage
information. The CRUM maintains a count of the amount of toner consumed. When the count reaches
set values, warning and error messages appear to notify the user when near and end of life status is
reached.
Note: Life ratings are based on A4 or A-size sheets at 5% coverage.
Note: Starter capacity cartridges are packaged with the printer when shipped from the factory.
These starter cartridges are not available for order.
Standard, high-capacity, and extra high-capacity Toner Cartridges are available for ordering.
Additional Drum Cartridges are also avaiable for ordering. See Consumables and Maintenance Items
for a Toner Cartridge and Drum Cartridge life and ordering information.
