10-126 Inverter Path Sensor On Jam Rap - Xerox DocuColor 12/DCCS50 Service Manual

10-126 Inverter Path Sensor On Jam RAP

The Inverter Path Sensor did not deactuate within the specified time after the Fuser Exit Sen-
sor deactuated.
Initial Actions
Refer to BSD 10.8, 10.9, 10.11 and 10.12 for the following procedure.
Check for the following:
• Proper Nip Drive force on the Inverter Roll
• Obstructions in the paper path
• Clean the Inverter Path Sensor and ensure that the sensor actuator moves freely.
• Ensure that connectors P/J412A, P/J417A
Drive PWB and the Inverter Path Sensor, and there are no obvious crimped or broken
wires.
Procedure
Enter dC330 010-125 Inverter Path Sensor. Press Start. Actuate the Inverter Path Sensor
actuator. The display changes from L to H.
Y N
The display is a constant H.
Y N
Go to Flag 1 on BSD 10.8 and check the harness for an short circuit. If the harness is
good, replace the Inverter Path Sensor
Connect the meter from P/J412A-8 on the IOT Drive PWB to GND. Actuate the Inverter
Path Sensor actuator. The voltage at P/J412A-8 goes from less than +1.0 VDC when
the sensor is deactuated, to +5 VDC when the sensor is actuated.
Y N
There is +5 VDC between P/J412A-9 and P/J412A-7 on the IOT Drive PWB.
Y N
Go to Flag 2 on BSD 10.8 and check the harness for a short circuit. If the har-
ness is good, replace the IOT Drive PWB
Go to Flag 1 and Flag 2 on BSD 10.8 and check the harness for an open circuit. If
the harness is good, replace the Inverter Path Sensor
tinues, 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.
Y N
Replace the IOT Drive PWB

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 decreases momentarily 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 decreases momentarily 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 on BSD 10.9 and check the harness and connectors. If the
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 VDC.
Y N
Replace the IOT Drive PWB
Replace the Inverter Motor (PL
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 (PL
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 Inverter Path Sensor.
