Quick answer
A printer error has occurred (no further detail given); while active the printer cannot print or scan. Contact your nearest Canon service center to request a repair. Unplugging erases stored faxes.
Hazard: This step carries a risk of injury or permanent damage. Power the printer off, let it cool, and check your model's manual before opening any panel.

Other Canon error codes
- 5B00Canon states only "Printer error has occurred" and gives no user step — it directs the owner straight to a Canon service centre. Canon does not describe 5B00 as a waste ink absorber message, despite that being the common third-party interpretation. The absorber wording belongs to codes 1700, 1701 and 1712.
- 5100Canon states "Printer error has occurred". The documented remedy is a carriage-jam procedure: press Stop, turn the printer off, then check that the print head holder is not obstructed by transportation tape or jammed paper and remove any obstruction. Canon warns specifically not to touch the white belt inside the printer.
- 5107A printer error has occurred (no further detail given). Power the printer off, unplug it, then reconnect and restart. If unresolved, contact an authorized Canon service center. Avoid tilting the printer during relocation to prevent ink leakage.
- 5200Canon states only "Printer error has occurred". The documented remedy is to turn the printer off, unplug it, plug it back in and turn it on, then contact a Canon service centre if that does not clear it. Canon names no component, so this is not specifically a printhead overheating message.
- 5400A printer error has occurred (no further detail given). Power the printer off, unplug it, then reconnect and restart. If unresolved, contact a Canon service center for repair.
- #001The original document is jammed in the ADF feeder during a fax/scan job. Remove the jammed original per the paper-jam troubleshooting section.
