10-132 Duplex Path Sensor On Jam Rap - Xerox DocuColor 12/DCCS50 Service Manual

10-132 Duplex Path Sensor On Jam RAP

The Duplex Path Sensor did not actuate within the specified time after the start of Reverse
Feed.
Initial Actions
Refer to BSD 10.8, 10.9, 10.10, and 10.12 for the following procedure.
Check for the following:
• Obstructions in the paper path.
• Contamination on the Duplex In Roll
• Ensure that connectors P/J412A, P/J417A, and
Drive PWB and there are no obvious crimped or broken wires.
Procedure
Enter dC330 010-132 Duplex Path Sensor. Ensure the Drawer is closed. Press Start. The
display indicates L.
Y N
Connect the meter from P/J420-A2 on the IOT Drive PWB to GND. The
cates less than +1.0 VDC.
Y N
There is +5 VDC between P/J420-A3 and P/J420-A1 on the IOT Drive PWB.
Y N
Go to Flag 8 on BSD 10.10. Check the harness for a short circuit. If the harness
is good, replace the IOT Drive PWB
Check the actuator for the Duplex Path Sensor. If it is good, go to
on BSD 10.10 and check the harness for an open circuit. If the harness is good,
replace the Duplex Path Sensor
Drive PWB (PL 9.2).
Replace the IOT Drive PWB (PL 9.2).
NOTE: In the following step, to block the Duplex Path Sensor, open the Drawer then open the
baffle (Jam Clearance Lever 3) on the bottom of the Drawer. Place a sheet of paper on the baf-
fle then close the baffle. CLose the Drawer.
Block the Duplex Path Sensor with a sheet of paper. The display indicates H.

Go to Flag 7 on BSD 10.10. Check the harness for a short circuit. If the harness is good,
replace the Duplex Path Sensor (PL

Go to Flag 4 on BSD 10.8 and check the harness for an open circuit. If the harness is
good, replace the Release Solenoid
Press Start. The voltage at P/J412A-14 momentarily goes to approximately +12 to
+15 VDC then returns to +24 VDC.

Replace the IOT Drive PWB
Replace the Release Solenoid
Enter dC330 010-026 Inverter Roll Solenoid Release. Press Start. The Release Solenoid
deenergizes.
Y N
Press Stop. +24 VDC is measured between P/J412A-12 and GND.

Go to Flag 5 on BSD 10.8 and check the harness for an open circuit. If the harness is
good, replace the Release Solenoid
Press Start. The voltage at P/J412A-12 momentarily goes to approximately +12 to
+15 VDC then returns to +24 VDC.

Check for obvious damage, missing and/or broken Drive Motor gear assemblies and drive
belts that would cause the paper to be slow to actuate the Duplex Path Sensor.
