• Code: E061
• Description: Incorrect paper size setting for the 1st drawer jam
• Causes:
• Remedy: If any paper remains in the equipment or drawer, remove it. Match the paper size of the drawer setting and the one in the drawer. * Paper size detection is performed at the first sheet of paper when the drawer is opened or closed, or when the power of the equipment is turned ON.
