My Canon Pixma MX 360 will not work. I keep getting the message "Load paper and press ok" but it has paper but does not seem to take it in.

SOURCE: I keep getting paper jam messages when there is no paper jam.

Hi,
Remove the jammed paper. Unplug the printer from the mains and PC. Inspect the rollers, etc for tiny paper piece(s) that may be stuck, or other debris. Try to clean rollers and make sure they are dry.
Keep printer unplugged for about 2 minutes and replug and try a test print.
Also make sure that you have waited long enough for the printer to heat up before giving a print job.
Finally, it could be an issue with the paper sensor. If this is the case, you will probably have to take the printer in for servicing..

Hello! I have solved your problem! The first thing you need to do is extend the back paper holder all the way up. This should uncover a long rectangular hole. There is a plastic piece with 2 arrows pointing to the right on it (if you are looking at the back straight on). Simply push them to the Right and it will pop up on the Left side. You can now lift that piece out and VOILA there is your misfed paper! Just reinsert the rectangular piece back in after you have taken the misfed paper out! -Gary Maples

Look carefully because it is a cassette on the bottom of your canon mx850... so the solution is: or you fill that cassette or you switch your canon (it is a button for that) to take the paper from the top...

On the control panel for the printer, there's a Feed Switch button that's easily touched by accident. Ensure the Feed Switch is set to the paper source you're using (e.g. either the back or front). The graphic of the printer next to the Feed Switch button will light up to indicate the paper tray it's attempting to use.
