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