[QUOTE="gwizzit, post: 215671, member: 14049"] UPDATE: I am nothing if not persistent! A further inspection revealed the problem. There is a "gearbox" that controls the paper feed rollers. Inside this gearbox there is a cog with a pin that attaches to the crank arm that pushes the pick-up rollers onto the paper stack. This cog has some "cams" on its shaft that are regulated by a "spring". This "spring" is a plastic lever which is part of the chassis of the gearbox... and the base of the arm has a slight CRACK (!) such that it no longer exerts enough pressure onto the cams to stop the cog at the designated points, allowing the cog & cam to continually rotate. This causes the pick-up rollers to continually bang against the paper stack, but fail to collect a sheet. The idea of the gearbox is that the motor drives it first in one direction to collect a sheet, then, as the paper passes over the sensor (mentioned above), the motor is reversed, the roller drive disconnected, and the forward rollers take over and drag the paper through past the print heads. I have emailed Canon to see if I can buy a new gearbox/chassis and will post a further update when I hear back from them. Meanwhile if anyone knows where I can get one, or has a suggestion about repairing the broken "spring", please let me know! P.S. I don't know if I am just unlucky and this is an uncommon problem ... but I would hazard a guess that the gearbox is a common component in the MG series (maybe others?) so this may apply to more printers than just my MG2550s !
