Occurrence of a jam is judged by whether paper is in the sensor area at the timings stored in the DC Controller.
When the DC Controller judges that a jam has occurred, the printing operation is stopped and the jam is notified to the Main
Controller at the same time.
The following shows the jams that are detected.
Jam name
Details
Pickup delay jam 1
When the Registration Sensor (SR5) fails to detect the leading edge of paper after the start of image
formation and before the start of re-pickup
Pickup delay jam 2
When the Multi-purpose Tray Paper Sensor (SR6) fails to detect the leading edge of paper within a speci-
fied period of time after the start of pickup from the Multi-purpose Tray
Pickup Stationary Jam
When the Registration Sensor (SR5) fails to detect the trailing edge of paper within a specified period of
time after the start of re-pickup
Fixing delivery delay jam
When the Fixing Delivery Sensor (SR3) fails to detect the leading edge of paper within a specified period
of time after the start of re-pickup
Fixing delivery stationary
jam
When the Fixing Delivery Sensor (SR3) fails to detect the trailing edge of paper within a specified period
of time after the Registration Sensor (SR5) detects the trailing edge of paper
Internal stationary jam
When one of the following sensors detects presence of paper at power-on, door close, or before/after print
operation
• Registration Sensor (SR5)
• Fixing Delivery Sensor (SR3)
• Delivery Sensor (SR4)
Door Open Jam
When one of the sensors detects presence of paper when door open is detected during printing
Wrapping jam
When the Fixing Delivery Sensor (SR3) turns OFF after the Fixing Delivery Sensor (SR3) detects the
trailing edge of paper and before detection of a fixing delivery stationary jam is started
Duplex Re-pickup Assem-
bly Jam
At 2-sided print, the paper was reversed, but the Duplex Re-pickup Sensor (SR22) failed to detect the
leading edge of paper within a specified period of time.
Delivery Delay Jam
When the Delivery Sensor (SR4) fails to detect the leading edge of paper within a specified period of time
after the Fixing Delivery Sensor (SR3) detects the trailing edge of paper
Delivery Stationary Jam
When the Delivery Sensor (SR4) fails to detect the trailing edge of paper within a specified period of time
after the Delivery Sensor (SR4) detects the leading edge of paper
