Abstract
A document feeder employs a lifting lever to lift stacked documents away from a feed roller each time a document is being fed away from the stack. In this way the separation of documents is enhanced, providing a mechanism that more readily accommodates documents of varying shapes, thicknesses, and materials. The feeder uses a motor linked by one-way clutches to feed mechanisms for documents and for labels, stacked separately. The motor is driven in one direction to feed documents and in the other direction to feed labels. A moistener is provided below the paper path, and the moistener is mounted so that it can be slidably removed. When it is removed, feed rollers are permitted to relax and move apart which helps in the clearing of jams.
