How to solve error C000 on Canon Pixma MX870 and MX860

MX870, MX860, MG520...

Solution 1:
  1. Switch off the printer
  2. Disconnect the power cable
  3. Open door:



  4. Remove the orange protective tape (A) and remove the white polystyrene (protective equipment) (B).



  5. Verify in the printer there is no protective equipment:


  6. Close the door.
  7. Connect the cable and switch on.

Solution 2 :
- Check for any foreign body in the printer: piece of paper, paper clip...
- Check for any paper jams.


Solution 3:
- This error code C000 could be made by an empty cartridge: check for this.

i´m so happy to find your helpful solutions. And afterwards i find a small peace of paper inside the printer. i´ve never looked behind the "printerhead", nearly as your posted picture.

the german canon support service can´t get any sinful informations, but you did it.

thanks a lot

I just fixed this problem in my MX860 by taking the ink cartridges and printer head out, cleaning excess ink from around the printer head with a lint-free cloth (making sure not to touch the parts where ink come out) and then re-seating the head and ink cartridges.

I received error C000 and ound a recently replaced ink tank was not seated properly. Pushed it firmly into place and all was fixed.

I removed the print head (the carrier of the ink cartridges that is released by raising the bar around the cartridges) and cleaned it with a mixture of water and rubbing alcohol with a q-tip.
Dried it all with a dry tissue and replaced the print head and cartridges.
That did the trick.

Thank you so much. This saved me from buying a new printer. I looked inside and found a paperclip behind the ink cartridges. Once I removed it the printer worked again.

Thanks! saved me taking my printer to be repaired. I discovered a cartridge wasn't 'quite' pushed in all the way. So worth taking another look:)

Another happy person. It was a paper jam for me. Why could Canon's error message have been clearer?

Thank you.

this error code is happening on my MX895 as soon as I plugged it in (brand new). Tried checking for cartridges and foreign objects but nothing. Any suggestions?

Hi Noa,

Are you sure there is any protective equipement in the printer ?

Thank you, thank you, thank you! I didn't notice that I had dislodged the yellow print cartridge when I replaced the magenta one! Simple fix.

Thank you! From your post I checked the insides of my Pixma MX882 & discovered that the replacement cartridge wasn't snapped all the way in. Even though the posts are about other models, this was the fix on mine too. Much appreciated.

THANK YOU SO MUCH!!!! Opened the lid dug around in the hidden areas and there was a straggling piece of paper! I had all but unscrewed the whole machine before! Thank you again this saved my day and my pocket from buying another printer!

I think you're all people working for canon companies telling so much liars ! i would make a therapy myself for such paranoia...

What worked for me was switching the printer off, opening the cover to the position where you can change the ink cartridges, and turning it on. It then ejected a sheet of paper. Once it had stopped making all the "switch on noises" I closed the cover and it worked. Could be co-incidence of course, but it worked for me.
