Canon 5B00

Quick answer

Canon support code 5B00 means the ink absorber (waste ink pad) is full or nearly full. The printer stops to prevent ink leaks; contact Canon service to replace the absorber.

What does “Canon 5B00” mean?

The printer's internal pad that catches waste ink during cleaning has reached its limit.

What causes it?

  • Many head cleanings over the printer's life
  • Heavy printing volume

Steps to try

Stop when the issue is resolved.

  1. Turn the printer off and on to confirm the code.
  2. Note the model number and code.
  3. Contact Canon support or an authorised service centre for absorber replacement.
  4. Consider cost: on older printers, replacement may cost close to a new printer.
