Abstract
Conveyance modes include a registration mode accompanied with skew correction and a registrationless mode unaccompanied with skew correction. When a jam occurs, the controller interrupts a job, and invokes blank-feed processing starting from a state with all sheets re-set. On invoking blank-feed processing, the controller checks the conveyance mode and recognizes the number of jams. If the conveyance mode is the registration mode and in addition the number of jams has not reached a threshold number of jams, the controller invokes blank-feed processing in the registrationless mode.
