Check the error displayed on the control panel and follow the instructions to remove the jammed paper, including any torn pieces or jammed staples. The LCD screen displays animated instructions that show you how to remove jammed paper or staples. Next, select OK to clear the error.
Never touch the buttons on the control panel while your hand is inside the printer. If the printer starts operating, it could cause an injury. To avoid injury, be careful not to touch any protruding parts.
Never touch the areas inside the booklet finisher that are marked with caution labels. Those areas may be very hot and high temperature may cause burns.
Remove the jammed paper carefully. Removing the paper with too much force may damage the printer.
If paper jams occur repeatedly, you might be able to resolve the problem by selecting On as the Printout Alignment Improvement setting. Note that printing may take longer.
