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.
THANK YOU SO MUCH!!!!! I too found a small piece of paper behind the printerhead where i never would have looked. my husband and i had looked in what we thought every possible space, and then i found you. and checked behind the printer head and Wha La!! LIFESAVER xxx

thank u very much i will find to fix erroe C000
Canon Pixma mp648, u are great i can fix it and can use my print again....
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:)
Errors on printing can really result in serious inconveniences and it is great to know that there are fixes that can offer solutions. Thanks for sharing a valuable tip. I'll be looking forward for more interesting posts from your blog.
