Canon rr2200 2800 3300 Common Faults

Hi all,

Remember I said this is not just about me. We've got to share knowledge and help others. To this end, I've tried to list a few common technical problems that you may call out an engineer for but may not need to now. I'll add one per post to give others a chance to add their own experiences too.

Models Canon ir2200 ir2800 ir3300 (but can relate to other copiers too!)


1. When feeding A4 Documents through the automatic document feeder, the document stops and display asks for A3 paper to be installed.

This problem is normally to do with one of the document sensors just to the right of your a4 document when it is placed on the feeder - there are 3 in total. For A4 the machine uses only 1.

Causes and solutions

- either you've placed some other documents beside your original on the doc tray for convenience. These documents are covering the A3 document sensor so the machine thinks that you want to feed an A3 document - remove those documents (not being rude)

- The sensor flag that sits proud of the document tray waiting to be covered by a document (usually A3 or your incorrectly placed doc we mentioned above) is not raised high enough so the optical sensor beneath the covers is actuated as if there was an A3 document. This is usually caused by what's known as a 'lazy sensor'. The shaft that this sensor pivots on can become dry or dirty, or both. Just get a can of WD40, lubricating spray oil of some kind with a straw for precision - then aim the spray at the base of the sensor arm - you can see where it sits by looking under it from the left. Spray away for a second or two and move the sensor arm. This will lubricate the arm shaft enough to allow the sensor arm to return to it's home position after it has been actuated (pressed).

See you soon
