I need to know if there's a way to reset this printer. I removed a jammed paper, but now it keeps saying the rear cover is open. From what I've read in the manual, this is "A recording paper jam occurred near the manual input tray". I already removed the paper, but it seems like the record is still there, so I need to erase the printer's memory somehow. If anyone has this printer or a similar model, please help, thanks.
