Paper Jam Detection

The Input/Registration Sensor (PS1) and the Paper Exit Sensor (PS3) detect paper moving through the printer. If a paper jam is detected, the DC Controller PCA immediately stops the printing process and 13 PAPER JAM or REMOVE PAPER JAM message is displayed. A paper jam can be detected under any of the following conditions:

•Input Paper Delay Jam: When paper does not reach the Input Paper Sensor (PS1) within the required time.

•Input Paper Stationary Jam: When paper does not clear the Input Paper Sensor (PS1) within a specified time.

•Paper Exit Delay Jam: When paper does not reach the Paper Exit Sensor (PS3) within the required time.

•Paper Exit Stationary Jam: When paper does not clear the Paper Exit Sensor (PS3) within a specified time.

•False Paper Jam: If the Rear Door is open, a paper jam message is displayed because PS3 senses a jam.

N o t e	A defective PS5 (Paper End Sensor) can also
	cause a paper jam when paper is fed from the MP
	Tray (Tray 1).
