Maintenance Items and Consumables
Maintenance items include the Transfer Unit and Fuser. The Feed Rollers are also
routine maintenance items, but individual procedures for their removal and
replacement are provided on
page 8-34 and page 8-54. Consumables consist of the
Toner Cartridges, Imaging Units, the Waste Toner Reservoir, and if present, the Staple
Cartridge.
Imaging Unit Removal
In this section, Imaging Unit often refers to the combination of the Toner Cartridges
and Imaging Units. When asked to remove the Imaging Unit, use this procedure:
1. Power down the printer.
2. Lift the Top Cover.
3. Grasp the top of the Toner Cartridge, and then lift the Imaging Unit out of the
printer.
4. Place the Imaging Unit in a light proof bag or other light proof container.
Caution
Leaving an Imaging Unit exposed to light for periods in excess of a 10 minutes
can quickly degrade its performance and result in early failure.
