Cause and Solution
IMPORTANT
A warning message is not displayed on your computer even if the toner cartridge is nearing the end of its life. The time when longitudinal white streaks on the printed paper or when the printing appears faint or uneven can be used as the rough guide to replace the toner cartridge. When you are replacing the toner cartridge, be sure to use the toner cartridge designed for this printer. When you purchase a replacement toner cartridge, contact your local authorized Canon dealer.
Before Replacing the Toner Cartridge:
The toner cartridge are consumable products. When the amount of toner is insufficient, longitudinal white streaks may appear on paper, or the printing may appear faint or uneven. If this symptom occurs, take out the toner cartridge in use before replacing it, then install it again after distributing the toner inside the cartridge evenly.
