Paper transport timing errors
During a print cycle, paper should move through the printer at a specific speed. A paper jam
occurs if the paper moves too slow or too fast. The following tables show E2, E3, and E4 paper
jams and the time windows required to create those jams. There are only two sensors: the
registration sensor and the exit sensor, for determining the jam status. The off or unused state is
with the actuators blocking the LED sensor circuit.
At power up or recovery Control Panel Message:
if the exit sensor only is on Paper Jam>Exit
if the registration sensor only is on Paper Jam>Fuser
if the registration sensor remains off Paper Jam>Fuser
if both the exit and registration sensors
are on
Paper Jam>Fuser
if the exit sensor remains off while printing Paper Jam>Tray
E2 paper jam timing (Control Panel message=Paper Jam>Tray)
Paper transport time needed to create an E2-1 jam
(Early paper feed - registration sensor shouldn't be actuated)
Tray 1 1.45~1.54 sec
Tray 2 2.48~2.58 sec
MBF0 .41 sec
Paper transport time needed to create an E2-2 jam
(Paper misfeed - registration sensor should be actuated)
Tray 1 1.92
Tray 2 2.95 sec
MBF 0.73 sec
E3 paper jam timing (Control Panel message=Paper Jam>Fuser)
Paper transport time needed to create an E3 jam: 3.03 seconds
