10-130 Duplex In Sensor On Jam Rap - Xerox DocuColor 12/DCCS50 Service Manual

10-130 Duplex In Sensor On Jam RAP

The Duplex In Sensor did not actuate within the specified time after the start of Reverse Feed.
Initial Actions
Refer to BSD 10.8, 10.9, and 10.12 for the following procedure.
Check for the following:
• Obstructions in the paper path.
• Skewed sheets with LE corner damage.
• Ensure that the Upper Inverter Roll (PL
• Ensure that connectors P/J412A, P/J417A
Drive PWB and the Duplex In Sensor, and there are no obvious crimped or broken wires.
Procedure
NOTE: In the following step, to block the Duplex In Sensor, open the Inverter Door. Slide a
sheet of paper up, and under, the mylar guides at the bottom of the Inverter 1 Upper Chute.
Enter dC330 010-130 Duplex In Sensor. Press Start. Open the Inverter Cover and block the
Duplex In Sensor with a sheet of paper. The display changes from L to H.
Y N
There display is a constant H.
Y N
Go to Flag 3 on BSD 10.10 and check the harness for an short circuit. If the harness
is good, replace the Duplex In Sensor
Connect the meter from P/J412A-5 on the IOT PWB to GND. Block the Duplex In Sen-
sor. The voltage at P/J412A-5 goes from less than +1.0 VDC when the sensor is not
blocked, to +5 VDC when the sensor is blocked.
Y N
There is +5 VDC between P/J412A-6 and P/J412A-4 on the IOT Drive PWB.
Y N
Go to Flag 4 on BSD 10.10 and check the harness for a short circuit. If the har-
ness is good, replace the IOT Drive PWB
Go to Flag 3 and Flag 4 on BSD 10.10 and check the harness for an open circuit. If
the harness is good, replace the Duplex In Sensor
ues, replace the IOT Drive PWB
Replace the IOT Drive PWB (PL 9.2).
Enter dC330 010-025 Inverter Roll Solenoid Nip. Press Start. The Release Solenoid ener-
gizes.
Y N
+24 VDC is measured between P/J412A-14 and GND.
Y N
+24 VDC is measured between P/J412A-13 and GND.

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.
Y N
Replace the IOT Drive PWB
Replace the Release Solenoid
Enter dC330 010-026 Inverter Roll Solenoid Release. Press Start. The Release Solenoid
energizes.
Y N
+24 VDC is measured between P/J412A-12 and GND.
Y N
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.
Y N
Replace the IOT Drive PWB
Replace the Release Solenoid
Enter dC330 010-020 Inverter Motor Forward. Press Start and Stop several times. The
Inverter Motor energizes and deenergizes.
Y N
Press Stop. +24 VDC is measured between P/J417A-13, 14, 17, 18 on the IOT Drive
PWB and GND.
Y N
+24 VDC is measured between P/J417A-15 on the IOT Drive PWB and GND.
Y N
Replace the IOT Drive PWB
Go to Flag 4 and Flag 5
harness and connectors are OK, replace the Inverter Motor
Press Start. The voltage at P/J417A-13, 14, 17, 18 on the IOT Drive PWB goes to
approximately +18.5 VDC.
Y N
Replace the IOT Drive PWB
Replace the Inverter Motor
Enter dC330 010-021 Inverter Motor Reverse. Press Start and Stop several times. The
Inverter Motor energizes and deenergizes.
Y N
Replace the IOT Drive PWB
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 In Sensor.
