012-132 (A-Finisher) Ent Sensor ON Jam
BSD-ON:CH15.3
Finisher Entrance Sensor does not turn On within a specified time after receiving the Sheet
Exit command (the sheet to be ejected has turned ON the IOT Exit Sensor 1).
Initial Actions
• Check that the Finisher Entrance Sensor is properly installed and free from foreign
objects and that the actuator is not broken.
• Power Off/On.
Procedure
Check the specifications of paper. Paper is in spec.
Y N
Replace the paper with new paper that is in spec.
Check the condition of the paper. The paper is in normal condition without any problem
that causes the paper to be bent or caught.
Y N
Resolve any problem that causes the paper to be bent or caught.
Check the transport path for a foreign object, deformed part, and paper dust. The
path is in normal condition.
Y N
Repair the deformed part(s) and remove the foreign object(s) and paper dust.
Check that the Finisher is installed properly. The Finisher is properly installed and properly
connected to the IOT.
Y N
Reinstall the Finisher properly.
Enter Component Control [012-140]. Actuate the Finisher Entrance Sensor. The
changes.
Y N
Check the connections of P/J8709 and P/J8729. P/J8709 and P/J8729 are securely
connected.
Y N
Connect P/J8709 and P/J8729 securely.
Check for an open or short circuit between J8709 and J8729. The
J8709 and J8729 are OK.
Y N
Repair the open or short circuit.
Measure the voltage between Finisher PWB J8709-6 (+) and GND (-). The voltage is
approx. +5VDC.
Y N
Go to Wirenet 7.2.36 A-Finisher +5VDC and check the +5VDC circuit.
