10-120 Inverter Path Sensor On Jam RAP
The Inverter Path Sensor detected paper when closing the Inverter Cover or when the power
was switched on.
Initial Actions
Refer to BSD 10.8 and 10.12 for the following procedure.
Check for the following:
• Clean the Inverter Path Sensor.
• Ensure that connectors P/J412B and P/J
151 are seated correctly on the IOT Drive PWB
and the Inverter Path Sensor, and there are no obvious crimped or broken wires.
• Ensure the Inverter is closed. Switch the power Off then On.
Procedure
Enter dC330 010-125 Inverter Path Sensor. Press Start. The display indicates L.
YN
Go to Fl
ag 1 and Fla
g 2 on BSD 10.8 and check the harness for a open circuit. If the har-
ness is good, replace the Inverter Path Sensor (PL 2.24).
If
the fault code is present and can not be cleared, replace the IOT Drive PWB (PL 9.
2). If the
fault code is not present and is occurring intermittently, go to Flag 1 and Flag 2 on BSD 10.8
and check the harness for an intermittent open circuit. If the harness is OK, replace the Inverter
Path Sensor (PL 2.24). If the problem continues, replace the IOT Drive PWB (PL 9.2).
10-125 Inverter Path Sensor On Jam RAP
The Inverter Path Sensor did not actuate within the specified time after the Fuser Exit Sensor
actuated.
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
• Proper Nip Drive force on the Inverter Rolls
• Cheat the Front Door Interlock and check the function and the position of the Inverter
G
at
e and Inverter Gate Solenoid dC330 010-005 Inverter Gate Solenoid (Exit) and 010-
006 Inverter Gate Solenoid (Invert).
• Clean the Inverter Path Sensor and Inverter Roll 2.
Al
so, ensure that the sensor actuator
moves freely.
• Ensure that connectors P/J412A, P/J417A and P/
J151 are seated correctly on the IOT
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.
YN
The display is a constant H.
YN
Go to F
lag 1 on BSD 10.8 and check the harness for an short
circuit. If the harness is
good, replace the Inverter Path Sensor (PL 2.24).
Connect the meter from P/J
412A-8 on the IOT Drive PWB to GND. Actuate the Inverter
Path Sensor actuator. The voltage at P/J412A-8 g
oes from less than +1.0 VDC when
the sensor is not actuated, to +5 VDC when the sensor is actuated.
YN
There is +5 VDC between P
/J412A-
9 and P/J412A-7 on the IOT Drive PWB.
YN
Go to F
lag 2 on BSD 10.8 and check the harness for a short circuit. If the har-
ness is
good, replace the IOT Drive PWB (PL 9.
2).
Go to Flag 1 and Fl
ag 2 on BSD 10.8 and check the harness for an open circuit. If
the harness is good, replace the Inverter Path Sensor (PL 2.24). If the problem con-
tinues, replace the IOT Drive PWB (PL 9.
2).
Replace t
he IOT Drive PWB (PL 9.2).
Ent
er dC330 010-025 Inverter Roll Solenoid Nip. Pre
ss Start. The Release Solenoid ener-
gizes.
YN
+24 VDC is measured between P/
J412A-14 and
GND.
YN
+24 VDC is measured between P/
J412A-13 and
GND.
