pull out the tray, you will see the roller in front. next to the roller on the same axle, is a black small metal type wheel. i forget the proper name for it, but if you slide that off the axle and replace the roller, the paper should start picking up correctly. you can take the part apart and remove some of the metal shavings inside and put it back on. or just order a new one. but in any case, it should print ok without it. oh, i just thought of it, it is called a torque limiter.
