Frequently Asked Questions
How long can an unused CART312 toner cartridge be safely stored?
Unopened CART312 toner cartridges can be stored safely for up to 24 months provided they are kept in a cool, dry place away from direct sunlight and heat sources.
Why does black toner output fade slightly before the cartridge runs out completely?
As the internal toner hopper empties, powder distribution inside the CART312 shell can become uneven. Removing the cartridge and gently rocking it horizontally redistributes remaining toner to restore output quality until a replacement is needed.
Is the drum unit built into the CART312 cartridge?
Yes, the Canon CART312 features an all-in-one design where the photosensitive drum and toner storage are combined into a single consumable unit, refreshing critical imaging components with every cartridge change.
