There is no power to the MBM.
NOTE The MBM is powered by
the printer through the
communication cable connecting
the two devices.
1. Check the communication cable
between the MBM and the printer for a
loose connection or damage. Make
sure that the connector is securely
screwed in. If the cable is damaged,
go to step 4.
2. Check wiring connection J1501 on the
MBM driver board.
3. Replace the MBM driver board.
4. If none of the above corrects the
problem, replace the MBM unit.
13.12.09 Jam In Left Accessory Stay jam. Inlet-paper sensor PS1501
remained activated longer than expected.
This signal is generated by sensor PS1501
(paper-inlet sensor). PS1501 is located
under the lower entrance guide plate with
the sensor arm extending up through the
guide plate and into the paper path.
1. Check sensor PS1501 and flag for
smooth operation and damage,
making sure its movement down
through the lower plate is free and is
not touching the sides of the cutout on
the lower guide plate. If there is
damage, go to step 7.
2. Check for any damage or obstructions
to the entrance to the upper and lower
guide plates. If there is damage, go to
step 7.
3. Inspect the upper entrance guide plate
to make sure its alignment allows the
sensor arm to move freely through the
hole cut in it for the sensor arm. If
there is damage, go to step 7.
4. Check for excessive paper curl as
paper leaves the fuser. Damp paper
could be the cause.
5. Clean PS1501 by gently blowing air
into the sensor.
6. Check connection J1503 on the MBM
driver board.
7. If none of the above corrects the
problem, replace the MBM unit.

inlet sensor PS1501 within the expected
time.
This signal is generated from sensor
PS1501 (paper-inlet sensor). PS1501 is
located under the lower entrance guide
plate with the sensor arm extending up
through the guide plate and into the paper
path.
1. Check for excessive paper curl as
paper leaves the fuser. The cause
could be damp paper.
2. Check for any damage to the entrance
guide plates.
3. Check the PS1501 sensor, sensor
arm, and sensor flag for smooth
operation and damage.
