012-212 Stacker Tray Upper Limit Failure RAP

BSD-ON:12.24
After the Stacker Tray started descending, the Stacker Upper Limit Sensor remained ON.
Initial Actions
• Power OFF/ON
• Remove obstructions under the tray.
Procedure
Check the tray raise/lower mechanism for foreign substances and distortion. No distortion or
foreign substances are found in the tray raise/lower mechanism.
Y N
Clear away the foreign substances. Correct the distortion.
Execute Component Control[012-264 Stack Height Sensor 1]. Actuate the Stack Height Sensor
1 with paper. The display changes.
Y N
Check the connections of J8873 and P/J8988.
correctly.
Y N
Connect J8873 and P/J8988.
Check the wire between J8873 and J8988 for an open circuit or a short circuit (BSD
12.24). The wire between J8873 and J8988 is conducting without an open circuit or
a short circuit.
Y N
Repair the open circuit or short circuit.
Measure the voltage between the Finisher PWB P8988-16 (+) and GND (-) (BSD 12.24).
The voltage is approx. +5VDC.
Y N
Replace the Finisher PWB (PL
Measure the voltage between the Finisher PWB P8988-17 (+) and GND (-) (BSD 12.24).
Actuate the Stack Height Sensor 1 with paper. The voltage changes.
Y N
Replace the Stack Height Sensor 1
Replace the Finisher PWB (PL 23.16).
Alternately execute Component Control[012-060 Stacker Motor up ON] and
trol[012-061 Stacker Motor down ON]. The Stacker Motor
