012-132 H-Transport Entrance Sensor On JAM RAP
BSD-ON:12.14
After the Engine Fuser Exit Sensor turned On, the H-Transport Entrance Sensor did not turn
On within the specified time.
Initial Actions
• Power OFF/ON
Procedure
Check the Transport Roll for wear and paper powder. The Transport Roll is ok.
YN
Replace the Transport Roll.
Check for foreign substances, distortion and paper powder in the paper transport path. No
distortion, foreign substances, or paper powder are found in the paper transport path.
YN
Clear away the foreign substances and paper powder. Correct the distortion.
Execute Component Control[012-190 H-Transport Entrance Sensor]. Actuate the H-Transport
Entrance Sensor (PL 23.4) with paper.
The display changes.
YN
Check the connections of J8861 and J8987. J8861 and J8987 are connected cor-
rectly.
YN
Connect J8861 and J8987.
Check the wire between J8861 and J8987 for an open circuit or a short circuit (BSD
12.14).
The wire between J8861 and J8897 is conducting without an open circuit or
a short circuit.
YN
Repair the open circuit or short circuit.
Measure the voltage between the Finisher PWB P8987-4 (+) and GND (-) (BSD 12.14).
The voltage is approx. +5VDC.
YN
Replace the Finisher PWB (PL 23.16).
Measure the voltage between the Finisher PWB P8987-6 (+) and GND (-) (BSD 12.14).
Actuate the H-Transport Entrance Sensor with paper. The voltage changes.
YN
Replace the H-Transport Entrance Sensor (PL 23.4).
Replace the Finisher PWB (PL 23.16).
Power OFF. Open the H-Transport Top Cover. Cheat the H-Transport Interlock Sensor. Power
ON.
The H-Transport Belt rotates.
YN
Check the connections of P/J8862 and J8987. P/J8862 and J8987 are connected
correctly.
YN
Connect P/J8862 and J8987.
Check the wire between J8862 and J8987 for an open circuit or a short circuit (BSD
12.14).
The wire between J8862 and J8987 is conducting without an open circuit or
a short circuit.
YN
Repair the open circuit or short circuit.
Measure the resistance of the H-Transport Motor between each point of J8862-1/2/5/6
(BSD 12.14).
The resistance is approx. 20Ohm.
YN
Replace the H-Transport Motor (PL 23.4).
Measure the voltage between the Finisher PWB J8987-21/22/23/24 (+) and GND (-),
(BSD 12.14).
The voltage is approx. +24VDC.
YN
Replace the Finisher PWB (PL 23.16).
Replace the H-Transport Motor (PL 23.4). If the problem persists, replace the Finisher
PWB (PL 23.16).
Replace the Finisher PWB (PL 23.16).
