Canon imageclass D1120 printer says: feeder paper jam,

Canon Imageclass D1120 ADF does not feed.

Canon 1180 error code E005 200

try to disconnect the feeder form the main unit and if still there is check document error then brother it is related to firmware(software)as i have encountered such in 3 machine before also but they were without feeder. so first disconnect the feeder connector from main unit .

first of all try to clean trays picked up rollers and also look for a piece op paper or something else in internal paper path

This is caused by dirt/debris stuck to your ADF scanner glass. When you use the feeder on these type of machines what happens is that your documents are fed over a strip of glass when they are scanned. So anything stuck to the glass is scanned as a solid "line". You just need to locate and clean the strip glass. It will be located 1 of 2 places on your machine. The first location would be just to the left of the larger main glass. Just look for a strip of glass about an inch wide running from the front towards the back. The other location is harder to find as it would be located inside of the feeder assembly. Sometimes you have to open the feeder unit and look for the glass strip inside. But most machines it is located just to the left or right of the large main glass. Since your copies are fine when you use the main glass then be assured that the strip glass is what is causing this problem.
Good Luck and Thank You for using Fixya.

remove paper as manual

chances are theirs either something that got lefted in the assembly afterward like a sticker,I would have the paper tires replaced, to prevent future problems .

you have support of a roller feeder broken open the right door and see if the roller that you see is oin good position.try to glue the plastic support.
