Publication number: 20160114602Abstract: Upon a misfeeding of any of second and subsequent sheets in paper feeding by a paper feeding unit during duplex printing, a controller drives the paper feeding unit to perform a paper feeding retry at one or more of paper feeding timings in a paper feeding schedule for duplex printing. The paper feeding schedule for duplex printing specifies the paper feeding timings by the paper feeding unit and paper refeeding timings by a paper refeeding unit for a case other than the misfeeding of any of the second and subsequent sheets in the paper feeding by the paper feeding unit such that the sheet refed from the paper refeeding unit and the sheet fed from the paper feeding unit are alternately conveyed to a printing unit.Type: ApplicationFiled: October 20, 2015Publication date: April 28, 2016Inventors: Akihiro YAMAGATA, Masashi HARA
