I have a Pixma 4700 (Canon) and it says there's a paper jam when doing a double sided printing. I have opened it every way and there's nothing in there, the printing if all off, you can't read anything at all, how do I fix this?
Contact customer support, they are awesome and will try other things to fix it, if they can't fix it and you are under warranty they will send a new printer to you. I would try using the alcohol and q-tip under the black holding box, that might help.
Just an update, a very nice Young man helped me go through many steps and came to the decision it was broken. I got a new printer… thank you to the man who helped me and to Canon great service.
I did put it in the post, it's a Canon Pixma TR4700. It's not even a year old and isn't used often. It was working fine till I tried to do a double sided printing. Then the error came up, it does jam but only when I try to do a double sided printing;...
I had that happen as well, I took a Q-Tip with rubbing alcohol and gently wiped my clear stripe by the ink cartridge's, that worked for me, I hope it helps you.
