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