Consumables and maintenance – printer unit > 100

This section explains how to replace consumable and 
maintenance items when due. As a guide, the life expectancy of 
these items is:

Toner — estimated 15,000 Letter pages at 5% coverage.

The printer unit is shipped with sufficient toner for 7,500 
Letter pages in the print cartridges.

Image drum — estimated 30,000 Letter pages at 3 pages 
per job — will vary depending on the number of printed 
pages per job.

Transfer belt — Approximately 100,000 Letter pages

Fuser — Approximately 100,000 Letter pages

At any time, you can check how much of each consumable/
maintenance item is left by using the appropriate menus. For 
example, enter the menu system and follow the path:

Configuration>Supplies Life>Cyan Toner

The percentage of Cyan Toner remaining is displayed on the 
display panel and the printer unit then returns to the ready to 
print status.

The display panel provides messages to the effect that 
consumables/maintenance items are running low or nearing end 
of life followed some time later by a message that replacement is 
required. You should replace the item as soon as possible after 
this message is displayed to avoid the possibility of print quality 
being compromised.

The paper feed rollers and the multi-purpose (MP) tray feed 
rollers do not have any replacement warning messages. 
Recommended replacement: after approximately 120,000 Letter 
sheets.
