Abstract
Preventing a paper jam as much as possible when actual paper size differs from designated paper size with increasing throughput by starting conveyance of a second sheet before detecting the length of a first sheet. Unless a register sensor has detected the rear edge (step S), start of feeding the next sheet is checked (step S). If started, a prescribed valueis applied (step S). If not started, a prescribed valueis applied (step S). Unless the rear edge is detected before a timer measures 'estimated time+prescribed value' (step S), a paper jam decision is made (step S). If the rear edge is detected before the timer measures the 'estimated time+prescribed value' (step S), the processing is completed without making a paper jam decision. Making the prescribed valueless than the prescribed valueenables reducing the paper jam caused by incorrect setting.
