Replacing a Toner Cartridge
Replacing a toner cartridge
Follow the instructions below to replace the toner cartridge.
To ensure high print quality, follow these simple precautions:
■
We recommend that you use Canon toner cartridges for optimum printing results.
■
Before you install the cartridge, ensure it has adjusted to room temperature
especially if the toner cartridge has been moved from a cold to a warm location. If
a cold cartridge is installed in the printer, condensation may form inside the cartridge
and cause degradation of print quality.
■
Before you install the cartridge, check the expiration date printed on the box. Old
toner cartridges can cause poor print quality. Always use a cartridge before its
expiration date.
■
We recommend that you clean the fixing assembly (see page 155) and clean the
transfer guide area (see pages 118 to 119) with a soft clean cloth, each time you
replace the toner cartridge.
1
Turn off the printer, using the power switch.
2
Open the top cover by grasping it at both sides and lifting it up completely.
• You won’t be able to replace the cartridge if the cover is only partially open.
• Make sure the transfer guide is closed before inserting the toner cartridge.
