2.4 Paper Jam Detection
The paper jam detection function supervises the paper state at power-on time and during printing.
In the event that the following state occurs, this function interrupts the printing process. If any of
the following errors is presented, recovery printing will be performed by removing the jammed
paper (namely by opening the upper cover, removing the jammed paper and closing the upper
cover).

Cause of error
• At power-on time, the paper is placed at the inlet sensor.
• After hopping operation is attempted three times, the leading part of the paper does not
reach the inlet sensor.
• At power-on time, the paper is placed at the paper sensor.
• The leading part of the paper does not reach the paper sensor within a predetermined
distance after the paper has reached the inlet sensor.
• The traiding part of the paper does not pass over the paper sensor within a predeter-
mined distance after the leading edge of the paper has passed over the paper sensor.
• The leading part of paper does not reach the outlet sensor within a predetermined
distance after the paper has reached the paper sensor.
• At power-on time, the paper is placed on the outlet sensor.
• The paper does not pass over the outlet sensor within a predetermined after the leading
part of the paper has reached the outlet sensor.
• The paper size check with the manual feed specified considers the reference size as free
size.
• The size of the paper is supervised by the inlet sensors 1. It is detected that the paper
does not pass over the inlet sensor 1 within predetermined range of 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 with the manual feed specified considers the reference size as free
size.
• Informs that a jam occurs in feeding papers to the Duplex Unit.
• Informs that a jam occurs in retracting papers into the reverse roller within the Duplex
Unit.
• Informs that a jam occurs in reversing papers in the reverse roller within the Duplex Unit.
• Informs that a jam occurs in impinge-feeding papers within the Duplex Unit.
• Informs that the 1st tray is pulled out in paper-remaining state when feeding papers
within the Duplex.
• Informs that an I/F time-out occurs between the printer and Duplex.
