Recovery from double media feed

摘要

Control (P) of imaging device ( 1 ) senses the period of time sensor ( 17 ) senses media ( 5 ) at input feed roller ( 16 a). When a too-long-over-sensor condition is sensed, drive of input feed roller ( 16 a) is terminated by operation of clutch (C). A feed roller ( 19 a) farther in the media path continue to operate. One sheet of media ( 5 ) is fed while a dual fed sheet is held in the nip of feed roller ( 16 a) and idle roller ( 16 b). Subsequently, feed roller ( 16 a) is again driven to feed the dual fed sheet for normal imaging.
