Abstract
An automatic recovery apparatus reduces the number of shut downs due to fuser misstrips in an electrophoto-graphic device. A fuser misstrip occurs if the lead edge of a copy sheet does not emerge from the fuser nip. The fuser roller and the photoreceptor drive roller are stopped. These rollers are driven in the reverse direction until the copy sheet is released from the fuser. The rollers are then driven in the forward direction so that the copy sheet is re-fused. This automatic recovery apparatus is used for a photoreceptor misstrip. If the copy sheet remains attached to the photoreceptor belt after passing the stripping zone, it will jam in the cleaner module. If a sensor detects the copy sheet is still attached to the belt after the stripping zone, then the photoreceptor belt is reversed and the stripping procedure is repeated.
