Question about Canon PIXMA MP780 All-In-One InkJet Printer

Machine thinks there's a paper jam

I have a Canon Pixma 780. Last night, I had a paper jam. I got the entire sheet of paper out of the back section of the printer, but now I can't get the machine to do anything until I "clear paper jam." I've opened and checked everything, rebooted it five times (sometimes by unplugging and sometimes with the on/off switch) and tried to clean the nozzles and cartridges, but it won't let me. Help!

    So rjf388, if the sensor "falls out or breaks", what's the next step?? I didn't hear anything fall out; I didn't hear anything break; I do hear a lot of grinding, but no production. Any ideas???

Ok what you have done is when you have pulled the paper jam out you have either still have a small piece of paper over the sensor or you have broken the sensor itself it sounds like the later, most people tend to pull out the paper backwards against the feed rollers and sensors just below the feed rollers and it causes the sensor to fall out or break i have seen this so many times,

Canon Pixma MP160 shows errors E3 and won't print


Hi there,

Error E3 : Check if the paper has jammed in the machine, reload the paper in the machine correctly and then press [Black] or [Color].

Paper Jams :
Cause : Paper jams in the paper output slot/ Auto Sheet Feeder.
Landscape Credit Card sized paper jams inside the machine.

Action : Remove the paper according to the following procedure.
1) Slowly pull the paper out, either from the Auto Sheet Feeder or from the paper output slot, whichever is easier.
* If the paper tears and a piece remains inside the machine, open the Scanning Unit and remove it. Be careful not to touch the components inside the machine at this time. After removing the paper, close the Scanning Unit, turn the machine OFF and turn it back ON.
* If you cannot pull the paper out, turn the machine OFF and turn it back ON. The paper will eject automatically.

2) Reload the paper into the machine and press [Black] or [Color].
* If you have turned OFF the machine in step , you will need to retry printing, because this operation cancels any print jobs in progress.

If you cannot remove the paper or the paper tears inside the machine, or if the paper jam error continues after removing the paper, contact a Canon service representative.
Important : You cannot load Credit Card sized paper in the landscape orientation.

Hope this helps.
Have a good day.

Paper jam


Remove the paper following the procedure below.
(1) Load a single sheet of the same paper in the Auto Sheet Feeder in portrait orientation.
Do not load it in the landscape orientation.
(2) Turn off the machine.
(3) Turn on the machine.
The paper is fed and then pushes out the jammed paper as it ejects.
If you cannot remove the jammed paper or the paper jam error continues after removing the paper, contact your Canon Service representative.

LCD Error message: Paper output slot. Thye paper is jammed. clear the paper and press OK.


A jam sensor may be stuck or have something stuck on it, causing the machine to think it is jammed. These sensors are normally located where the paper feeds into the printer, and where the paper exits the printer. Try forcing a sheet of paper through the machine in the direction paper normally. feeds. This may free up the jam sensors.

'paper jam' error on canon pixma ip4300


Hi guys, I eventually found a solution to the problem for my printer. With the top cover open, I pushed a sheet of 120 micron thickness A4 clear plastic binding cover through the exit tray as far as it would go to rest against the bottom row of rollers. I switched the printer off then back on again and as the rollers lifted momentarily, I pushed the sheet of plastic as far up through the machine as I could before the rollers went down again - it went in a fair distance. The printer then ejected the plastic sheet. I then put the plastic sheet into the paper tray and tried to print a blank document page. The plastic fed through cleanly and my printer has been working since without any error messages. I hope this works for you.
