Paper Jam Detection
The paper jam detection function monitors the paper condition when the power is turned on and during
printing. When any of the following conditions arises, this function interrupts the printing process. If any
of the following errors is encountered, printing can be recovered by removing the jammed paper (by
opening the upper cover, removing the jammed paper and closing the upper cover).

Paper size error
• The paper is in contact with the inlet sensor when the power is turned on.
• After hopping operation is attempted three times, the leading edge of the paper does not reach
the inlet sensor.
• The paper is in contact with the paper sensor when the power is turned on.
• The leading edge of the paper does not reach the paper sensor within a predetermined feeding
distance since the paper has reached the inlet sensor.
• The trailing edge of the paper does not pass over the paper sensor within a predetermined
feeding distance after the same has passed over the inlet sensor.
• The leading edge of paper does not reach the outlet sensor within a predetermined feeding
distance after the paper has reached the paper sensor.
• The paper is in contact with the outlet sensor when the power is turned on.
• The paper does not pass over the outlet sensor within a predetermined feeding distance after
the leading edge of the paper has reached the outlet sensor.
• The paper size check for manual feeding finds that the paper size is free size.
• The size of the paper is monitored by the inlet sensor 1. The paper is not detected by the inlet
sensor 1 within predetermined feeding distance.
• The inlet sensor 2 detects that the size of the loaded paper is A4 or larger, or smaller than A4.
The detected paper size differs from the paper size set by command or menu.
• The paper size check for manual feeding finds that the paper size is free size.
