How to Fix Canon Printer Error 5C20

The printer suddenly stops with a loud noise (clicking or grinding) and shows a 5C20 error message on the screen. This error means the printer’s control board can’t manage the part that moves the ink cartridges. Usually, this happens because the control board is broken.

Other possible causes include the ink cartridge holder being stuck, a loose strip inside, or a broken cleaning part.

1. Reset the Printer

Resetting your printer will clear its flash memory and reset the device, which often resolves issues like Error 5C20. Please note, however, that unplugging a Canon printer from the power outlet will delete any stored faxes.

  1. Press the power button on the printer and wait until it turns off completely.error 5c20-1
  2. Unplug the printer from the power outlet.error 5c20-2
  3. Wait for at least 30 seconds, then plug the printer back into the power outlet and turn it on. This will successfully reset your printer.

2. Check the Printer’s Print Head

If you hear a crackling or rattling noise when trying to print and see Error 5C20, the print head may be the source of the problem. To check this:

  1. Unplug the printer from the power outlet.
  2. Remove the printer’s cover panel to access the inside.
  3. Lift the orange or grey lever to the left of the ink cartridges, remove the cartridges, and inspect the print head for any obvious problems.
  4. If you notice any ink buildup or debris, try cleaning the print head gently. If it looks damaged, you may need to replace it.

3. Make Sure the Belt That Moves the Cartridge Carriage Is in Place

If the print head seems fine, the next possible cause of Error 5C20 is an issue with the belt that moves the cartridge carriage back and forth inside the printer to release ink onto the paper. This belt is located directly behind the cartridge carriage.

Remove the cartridge carriage and use a flashlight to closely examine the belt.
Check that the belt is properly in place and has not slipped off its track or wheels at either end of the printer. Also, make sure the belt does not need any lubricant.
If the belt feels dry, apply a very small amount of white grease to it using a Q-tip.
If none of the above methods resolve Error 5C20, the cause is likely a hardware issue that needs professional attention. In that case, contact your nearest Canon service center or a qualified printer technician and arrange to have your printer looked at and repaired.
