Replacing the Toner Cartridge
When the message for replacing the toner cartridge is displayed on the touch panel display, press [] on the bottom right and replace the toner cartridge for the displayed color.
When the Black toner or all of the toners run out completely and prints can no longer be made, a screen with instructions on how to replace the toner cartridge appears on the touch panel display. Follow the procedure described below to replace the toner cartridge.
If you press [Close], you can continue operations, such as setting modes and scanning originals, even if you do not replace the toner cartridge immediately.
The location of the toner cartridge is indicated in the following illustration.
WARNING
Do not burn or throw used toner cartridges into open flames, as this may cause the toner to ignite, resulting in burns or a fire.
If you accidentally spill or scatter toner, carefully wipe up the loose toner with a damp, soft cloth and avoid inhaling any toner dust. Do not use a vacuum cleaner that is not equipped with safety measures to prevent dust explosions to clean up loose toner. Doing so may cause damage to the vacuum cleaner or result in a dust explosion due to static discharge. 
CAUTION
Keep toner out of the reach of small children.
If toner is ingested, consult a physician immediately.
If toner gets onto your hands or clothing, wash it off immediately with cold water. Washing it off with warm water will set the toner, and make it impossible to remove the toner stains.
IMPORTANT
Use only toner cartridges intended for use with this machine.
For information on the supported Canon genuine toner, see "Consumables."
Do not replace toner cartridges until the message prompting you to do so appears.
You can replace a toner cartridge while the machine is printing.
The color of the toner to be replaced is displayed on the touch panel display. If multiple toner cartridges must be replaced, replace the toner cartridges in the following order:Black, Yellow, Magenta, Cyan.
If you continue copying or printing in black-and-white after cyan, magenta, or yellow toner runs out, do not remove the depleted toner cartridges from the machine.
You can display an error message informing the user that the remaining toner is low. For instructions on displaying the remaining toner error message, see "Displaying the Remaining Toner Error Message." For instructions on deleting the remaining toner error message, see "Deleting the Remaining Toner Error Message."
NOTE
Complete instructions on how to replace the toner cartridge can be accessed by pressing [Previous] or [Next] on the touch panel display.
If toner runs out during a print job, the remaining prints are made after you replace the toner cartridge.
If black toner is left, you can continue copying and printing in black-and-white. However, if a job is interrupted because cyan, magenta, or yellow toner runs out, copying and printing in black-and-white is only possible for functions other than the function being used for the interrupted job.
After replacing toner cartridges, if printed colors are different from the colors printed before you replaced the toner cartridges, perform [Auto Adjust Gradation] in [Adjustment/Maintenance] (Settings/Registration). (See "Automatic Gradation Adjustment.")
