2-80 Service Manual
5060-4xx
271 Paper Jam - check bin 1
Output bin
POST complete, first sheet of paper feeds into output bin x.
Note: Before proceeding with this service check run the Output Bin x Sensor Test and check for the failing
sensor.
Sensor Tests:
XNF Near Full (Upper part of sensor assembly)
F Full (Lower part of sensor assembly)
P Pass Thru Sensor
Step Actions and questions Yes No
1 DC motor cable connection - Make sure the DC motor
connector is correctly installed at J4 on the output
expander option board.
Is the cable installed correctly?
Go to step 2 Install the cable
correctly
2
DC motor mechanical linkage assembly - Check the
resistance of the motor on the cable connector. Check
the resistance between J4-1 and J4-2. The resistance
measures between 115 ohms and 135 ohms.
Is the resistance correct?
Go to step 3 Replace the DC
motor
mechanical
linkage assembly
3
DC motor mechanical linkage assembly - Check for
continuity between J4-1 and J4-2 and the case of the
motor. It measures infinity.
Is there continuity between J4-1 or J4-2 and the case
of the motor?
Note: If the motor is shorted from either J4-1 or J4-2
and the case of the motor, it may be necessary to
replace the output expander control board.
Replace the DC
motor
mechanical
linkage assembly
Go to step 4
4
Output expander board - Disconnect the motor cable
from J4 and check the voltages at J4 on the board.
Note: All voltages are approximate values:
J4-1 (motor idle) +24 V dc
J4-2 (motor idle) +24 V dc
J4-5 (motor idle) +5 V dc
J4-6 (motor idle) +5 V dc
Warning: Be careful not to short to adjacent pins on
the connector.
Are the voltages correct?
Replace the DC
motor
