ABSTRACT:
A system for automatically eliminating a paper jam in an electrophotographic device may be initiated by removing and re-inserting a paper cassette subsequent to the occurrence of the paper jam. If the paper cassette is removed and inserted, a paper jam eliminating mode is implemented to eliminate the paper jam. In one implementation, a controller detects entry and exit of the paper as the paper is propelled by a plurality of rollers to travel between spaced-apart locations along a path normally taken by the paper as the paper travels through the device, makes a determination of the occurrence of a paper jam due to an interruption of the travel of the paper along the path on a basis of any delay in the entry and exit, monitors a first sensor to detect removal and reinsertion of said paper cassette subsequent to the occurrence, and upon detection of removal and reinsertion of said paper cassette subsequent to the occurrence, eliminates the interruption by driving the plurality of rollers to expel paper from said conveyance path.
