Paper in 3310 HP

I have had exactly the same problem. Lost heaps of paper and very frustrated.

Last resort solution. Thought that the rollers that pick up paper have become smooth and not gripping paper. So waited until fault occured again (2 Pages later) did not press the ok button when asked to reload paper, and removed the back panel. Using a small artists brush dipped in metholated spirit I brushed the paper feed rollers that come in contact with the paper (not the rear visible rollers). Press the OK button and the paper feed rollers will rotate and try to pick up paper (two times) then will stop and ask for you to load paper and press OK again. Continue to press the OK button when asked, making the printer rotate the rollers while the brush is in contact with them until they have been thouroughly cleaned with the metholated spirit. I also slipper a sheet of 120 grit sandpaper dampened with metholated spirit under the rollers from the back and forced the printer to feed paper by pressing the OK button. Hold the sandpaper firm so that the rollers rotate on the sandpaper. This roughs up the roller surface.

Paper feed problem seem to be fixed.

Hope this works for you.

Cheers
