Fix Jammed Paper Feeder on Canon Pixma MP-780 All-in-one Printer Repair Video

http://thenerdshow.com repairs a Canon Pixma MP-780 All-in-one printer, scanner copier & fax when the top tray mechanism is jammed or stuck and won't feed paper. I guess this is a common problem that needs fixing with these multifunction printers. Repair tools needed: Long Phillips screwdriver and regular screwdriver for prying. After purchasing a screwdriver, uh, enlargement, we removed the screws and took off the side panels. Then we proceeded to disconnect the wiring and remove the scanner, control panel and upper housing, finally gaining better access and visibility to fix the jammed paper feed tray mechanism and stuck rollers. To perform the actual fix, we pry out the paper guide using a screwdriver and roll the rollers manually until they lock into position, putting the paper feed tray back in its original position atop the lifter cam. We don't usually repair printers because the time versus replacement cost is rather high, but this is something that can be fixed in a home shop without too much trouble.

I HAVE A CANON MP 830 PRINTER AND THE SAME PROBLEM AND DID YOU DO IN YOUR VIDEO BUT STILL THE SAME PAPER JAMMED

[yuvaw]

It worked! ...Kind of.

I fed it through a few times, was a little tough. It stopped jamming paper, but then gave me an Error 5100 (something stopping ink carts from moving to the left). So I looked inside, and behold! A bottle cap! I took that out and that seemed to solve it. But, I think running the cardboard through broke the little things that hold up all your loaded paper, so now I can only print if there's just one sheet in it at a time. Still, better than buying a new printer!

@GhostAholics did you use refill ink. take it to canon

[GhostAholics]

I have this same printer and have had no problems with it for five years, but today it says there is a problem with the printhead. I've taken the head out and cleaned it, but still not working. There was some ink covering the components, but now all cleaned. Any ideas?

Hey... first of all, thanks for the video. I have used it to disassemble the printer, and tried to play with this white round wheel with tracks, and set up the grey plastic piece that is being attached to it.

But got no success after all. I tried this three times. The "clear paper jam" error is still there. I believe there's a kind of a switch that is stuck in wrong position.

I got the printer from a used stuff store, it printed two pages for me and then turned on the "clear paper jam" light
