Installing or changing a toner cartridge
Toner is the powdered ink that produces the image on the paper.
Follow these steps to install a toner cartridge into the printer.
1. Open the printer access door.
2. If you are replacing a used cartridge, remove the old
cartridge and set it aside.
3. Unpack the new toner cartridge and gently rock it to
distribute the toner inside.
Save the protective bag. If you move or transport your printer,
you will need to remove the cartridge and transport it
separately in the bag.
Do not expose the cartridge to direct sunlight. Don’t expose it
to room light for more than five minutes, or the life of the
cartridge may be reduced.
Gently rock the toner cartridge.
Press the release button
to open the access door.
