Third-party status
UnknownChipped compatibles sold; no dated lockout reports found
We found no dated report of a Canon firmware update locking out compatible 075 toner on the MF663Cdw, and chipped compatibles are widely sold. But Canon's own manual lists a non-Canon cartridge message that stops printing, and we found no owner report confirming long-term success, so treat this as Unknown.
What to do now
- Before any firmware update, note your current firmware version (Menu > Management Settings > License/Other > Update Firmware > Version Information) and whether all four compatible cartridges are recognized, so you can tell if an update changed anything.[1][3]This only helps you spot a change; no source shows a way to roll firmware back.
- If a 'Cartridge communication error' appears, Canon's first step is to reinstall the toner cartridge. A seller suggests checking which single color fails before replacing a whole set.[1][3]Canon says problems caused by non-Canon cartridges are not covered under warranty.
What to buy instead
- Genuine Canon 075 / 075 H. Always recognized, with toner levels. Expensive per set.
- Compatible 075H with pre-installed chip. Sold for this printer. Pick a seller with a clear return policy.
- Account required
- No
- Cartridges
- Canon Cartridge 075 / 075 H
- Blocking firmware

Also applies to: Color imageCLASS MF665Cdw and MF662Cdw (same user guide and 075 toner); sellers also list LBP646Cdw and LBP647Cdw for 075
Third-party and remanufactured cartridges
- The MF663Cdw takes Canon Cartridge 075 (standard) and 075 H (high capacity). Canon rates 075 H at 3,500 black and 2,500 color pages.[1]
- Canon's user guide lists two kinds of non-Canon messages. One says the remaining toner amount 'cannot be displayed correctly' and recommends genuine toner. Another says 'Cannot print. A non-Canon or counterfeit cartridge may be inserted,' meaning printing stops until the cartridge is replaced.[1]
- Compatible 075 / 075H cartridges with pre-installed chips are sold for this printer. One seller says its batches are checked against current Canon firmware but that this is not a guarantee against future firmware.[2][3]
- On a Canon Community thread about non-Canon toner in an older Color imageCLASS (MF743Cdw), a community member says Canon 'do not block or force you to use OEM toner.' That thread is about a different model and toner.[4]
Canon account and subscriptions
- We found no Canon requirement for an account or subscription to print. The user guide's firmware and toner steps are done on the printer itself.[1]
Firmware that blocked cartridges
- Per Canon's user guide, firmware updates over the internet start when you press [Update Firmware] on the printer and accept the license. We found no automatic-update setting described in the guide.[1]
- We found no dated report naming an MF663Cdw firmware version that blocked compatible 075 toner.[2][5]
To see your version, print a printer status report or open the printer's web page. Compare it with the firmware list.
Workarounds that sources back up
- Before any firmware update, note your current firmware version (Menu > Management Settings > License/Other > Update Firmware > Version Information) and whether all four compatible cartridges are recognized, so you can tell if an update changed anything.[1][3] This only helps you spot a change; no source shows a way to roll firmware back.
- If a 'Cartridge communication error' appears, Canon's first step is to reinstall the toner cartridge. A seller suggests checking which single color fails before replacing a whole set.[1][3] Canon says problems caused by non-Canon cartridges are not covered under warranty.
What does not reliably work
- When the 'Cannot print. A non-Canon or counterfeit cartridge may be inserted' message appears, Canon's only listed fix is replacing the toner cartridge.[1]
What to buy instead

What we could not verify
- Whether compatible 075 toner keeps working after current or future MF663Cdw firmware updates (no dated owner reports found either way).
- Which exact non-Canon message compatible 075 cartridges trigger on this printer: the warning that toner level can't be shown, or the one that stops printing.
- Long-term print quality of compatible 075 toner. An r/printers owner bought a 075H compatible set in January 2026 but we found no follow-up.
