2.4Paper 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).

Error		Cause of error
Paper input jam	•	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.
Paper feed jam	•	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.
Paper exit jam	•	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.
Paper size error	•	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.
Duplex input jam re-	•	Informs that a jam occurs in feeding papers to the Duplex Unit.
move the paper
Duplex feed jam1 re-	•	Informs that a jam occurs in retracting papers into the reverse roller within the Duplex
move the paper		Unit.
Duplex feed jam2 re-	•	Informs that a jam occurs in reversing papers in the reverse roller within the Duplex Unit.
move the paper
Duplex feed jam3 re-	•	Informs that a jam occurs in impinge-feeding papers within the Duplex Unit.
move the paper
Duplex open jam re-	•	Informs that the 1st tray is pulled out in paper-remaining state when feeding papers
move the paper		within the Duplex.
Error 83	•	Informs that an I/F time-out occurs between the printer and Duplex.
