[SOLUTION] Canon D1120 duplex jamming

A client of mine has a Canon imageCLASS D1120 copier that would jam each time they tried to copy or print any double sided. I looked and looked for a jam, but couldn’t find any. It would print the one side and suck it back in and jam. I took a flashlight in the back and finally figured out what was happening — there was paper inside that was causing the jam.

Remove the paper tray and look for this green lever (as is shown in the diagram #1 in the picture below). Pull it down and remove the jam!

    Brmorris, you are a genius! You just saved my bacon at the office. Thanks! Who would have ever thought to look inside the machine for the problem when the error code comes up as check the back? Thanks again!
