Good to know
What is the part number for this cyan toner?
Canon lists it as 0261B001AA, with 0261B001 as the base part number.
Can I replace just the cyan cartridge?
Yes. Each GPR-21 colour is a separate cartridge, so you only replace the colour that has run out.
How to install the Canon GPR-21 Cyan Toner
- Open the front or top cover and let the printer cool for a few minutes if it has just been printing.
- Remove the used cartridge. On printers with a separate drum unit, take out the drum and toner together, then push the lock lever and lift the toner cartridge out of the drum.
- Unpack the new cartridge and gently rock it side to side five or six times to spread the toner evenly. Remove any protective strip or cover.
- Slide the cartridge into place (or into the drum unit until it clicks), refit the assembly and close the cover.
Storage and handling
Store spare toner sealed in its bag, lying flat, at normal room temperature and away from humidity and direct sunlight. Do not touch the drum surface or the roller, as skin oils and scratches can show up as marks on your prints.
Getting the most from each cartridge
When the printer shows a low toner warning, taking the cartridge out and gently rocking it can often give extra pages before it needs replacing. Toner save mode is handy for drafts and internal copies. Used cartridges can be dropped at a Cartridges 4 Planet Ark collection point for free recycling.
