Canon error P22 (scanner error)

P22 means the scanner unit failed to initialise. The scanner bar did not reach its home position or the lamp did not respond when the printer started. It is the segment-display equivalent of support code 5011 on newer models. While P22 is active the printer usually blocks all functions, including printing.

What causes it

  • Scanner lock switch engaged after a move (on models that have one)
  • Object or packaging under the glass
  • Scanner cable loose where the scanner unit hinges
  • Scanner motor or belt failure
  • Lamp or sensor failure

How to fix it, in order

Work down the list and stop when the printer recovers. The steps are ordered from most likely and least invasive to last resort.

  1. Restart with the lid closed

    Turn off, unplug for a minute, close the lid and power on. Watch through the glass edge for the scanner bar moving and lighting.

  2. Check for a scanner lock

    Some MX models have a lock on the underside or left side of the scanner. Slide it to the unlocked position.

  3. Inspect under the glass

    Open the lid and look for tape or debris at either end of the scanner bar's travel.

  4. Check the scanner cable

    Lift the scanner unit (the whole top) as if changing cartridges and look at the flat cable at the hinge. If it has pulled out of its connector, push it back in with the printer unplugged.

  5. Try printing

    If the printer reaches a ready state after restart, print a nozzle check. On some firmware the printer will print even if the scanner is dead once the error is dismissed.

Stopping it happening again

When it is not worth fixing yourself

If you would rather not work through this alone, a printer specialist can take a look with you on a screen-share and tell you honestly whether the machine is worth saving.

Frequently asked questions

Can I print with P22 showing?

Sometimes, after a restart, but the printer often refuses all functions until the scanner initialises.

Is P22 the same as 5011?

Yes. P22 is the segment-display version of the scanner error 5011.

Does a factory reset fix P22?

Only if a firmware glitch was the cause. It does not repair a scanner that does not move.
