Hi.

The feed roller may well have polished itself to the point it no longer has enough friction to work. I have found a good method of resurrecting printers with this fault is to lightly sand the surface with 320 to 600 grit wet and dry sand paper moistened with isopropanol, until it is slightly rough to the touch. Wipe it down with more alcohol, and try it. It often makes the thing work for another few thousand pages.
