the Exit Section.
1
Is the paper curled, waved,
or damp? YES
Change the paper.
Instruct the user in how to
store the paper.
2
Does the voltage across
PJ6A-5 on PWB-A and
GND change from DC24V
to DC0V after the Start Key
has been pressed?
YES
Adjust the stroke of the
Solenoid or check the
Solenoid.
NO
Replace PWB-A.

(PF-201) (PF-1D), PWB-G,
and/or M31.
5
Does the voltage across
PJ8A-8 on PWB-A and
GND change from DC5V to
DC0V when Duplex Vertical
Transport Sensor PC12 is
blocked by a sheet of
paper?
NO
Check the Actuator for
operation.
Check PC12.
6
Does the voltage across
PJ3A-10 on PWB-A and
