Abstract
A feeder for a electrophotographic printer to feed photo-sensitive paper onto the drum of the printer. Sheets of photo-sensitive paper are adhered to release paper. The sheets are separated from the release paper by rolling the sheets adhered to the release paper over a positioning roll, where separation occurs, and rolling the photo-sensitive sheets onto the drum and the release paper onto a take-up roll. The sheets are clamped at their front end to the drum the drum is rotated and the sheets are clamped at their rear end to the drum. The take-up roll is rotated by the driving force of a stepping motor and the frequency of the driving force is controlled to coincide with the rotational speed of the drum.
