Thanks for the tip. When I opened it to look for a piece of paper stuck inside, I noticed grease on the timing slit disk film. I cleaned it and all is OK.

Great advise! We had two elastics jammed down in there and when we surgically removed them the printer worked again! Thanks!

Worked, some pieces of paper jammed somehow and stuck half under the paperfeeder.

I got the 6000 error over and over but could find nothing.
What solved it ?
The door had not been opening automatically, I opened the front paper door manually and the error was gone and printing.

Papier uithalen. Het ding afzetten, opnieuw opzetten, een beetje stof vegen, opnieuw afzetten, opnieuw opzetten en dan werkte het.

I had the same problem and it was frustrating because nothing appeared jammed?
I tried power down and power back up again but the same fault appeared
However I noticed a previous post and you MUST leave it over 1 minute before powering back up!
Hey presto all is good!
We are trying to install it, brand new, and it is giving this error. It hasn't had paper in yet, obviously not dust etc.
What do we do now?

Hi Brenda,

Chek for any piece of packaging inside. If the error still persist, call the Canon support for exchange.

Bless your cotton socks! Simple advice can make the world of difference to a busy working mother! A bit of paper stuck down the side which I didn't notice until I peered around a bit more. Thank you Thank you Thank you!!!
Suddenly, my printer won't scan or copy. It'll print, but won't scan or copy, and I receive the Error 6000.

Hi there. I'm pretty much thinking my problem is actually a faulty part. When it turns on normally the roller thing rolls... now it starts to roll but then stalls and make a weird sound. Is it really viable to change a part yourself? Or is it time to move on. I've had this printer for a long time.

Hi AlleahF,

Try solution 3 here:

If problem persist, then a part maybe defective.

Thank you so much! Paper jam removed and now working removed!
Glad I checked before ordering a new one

FINALLY FIXED IT!!! No paper jam, no overhanging items, no other obstructions, power disconnected for 5 mins didn't help either.
I opened the section that you normally open to initiate printer cartridge replacement and noticed a build-up of black ink on the right hand side toward the back. Cleaned it off and bingo. Would be nice if Canon could supply some more helpful support information, i.e. check this, check that, check here, check there, etc. (MX926 Printer)

Really frustrating as haven't used it much ..and then all of a sudden it was grabbing three or more papers at a time. I pulled it apart to try fix but it is now in the rubbish bin. I wish things were built to last :(

Thanks for suggestions. Got 6000 error and power didn't help and print carriage was stuck to the right side. After reading all the suggestions about a piece of something stuck somewhere I unplugged everything and got it where I could see. Found a paper jam in the rear roller. It seems that the printer apparently fed two pages instead of one and the two pages got stuck back there when it tried to duplex to the second side or something (as one of the sides of one of the pages had print on it). Didn't even realize I could pull all that stuff out of the back to get to that roller but glad I poked around.

took out paper tray, lifted printer up and there were two jammed pieces of paper. Don't think that an error 6000 was very informative when it could have told me about a jam. Thank you for such a simple fix.
