I made a big mistake: I took apart my Samsung ML-2010 Laser Printer because the spongy roller had to be repaced and I didn’t know that the sponge material snaps out without tearing down the whole thing. Now that I’ve reassembled, some gears have flat ends on them, kind of like a letter D and I can’t figure out how to align the gears so that it will advance the paper sheets correctly.

If nothing else it’s a start. Samsung-ML-2010.pdf Here is a guide that will tell you how to post some images of what you are looking at Adding images to an existing question
