012-212 Stacker Tray Upper Limit RAP
BSD-ON:12.8/12.9
After the Stacker Tray started descending, the Stacker Upper Limit Sensor remained ON.
Initial Actions
• Power Off/On
• Remove obstructions under the tray.
Procedure
Execute Component Control [012-260 Stacker Upper Limit Sensor]. Actuate the Stacker Upper
Limit Sensor with paper. The display changes.
Y N
Check the connections of P/J8850 and P/J8810. P/J8850 and
nected correctly.
Y N
Connect P/J8850 and P/J8810.
Check the wire between J8850 and J8810 for an open circuit or a short circuit (BSD 12.9
Flag 2/Flag 2). The wire between J8850 and J8810 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 P8850-A12 (+) and GND (-) (BSD 12.9
Flag 2). The voltage is approx. +5VDC.
Y N
Replace the Finisher PWB (PL 17.12).
Measure the voltage between the Finisher PWB P8850-A11 (+) and GND (-) (BSD 12.9
Flag 2).
Actuate the Stacker Upper Limit Sensor with paper. The voltage changes.
Y N
Replace the Stacker Upper Limit Sensor (PL 17.10).
Replace the Finisher PWB (PL 17.12).
Alternately execute Component Control [012-060 Stacker Motor up ON] and Component Con-
trol [012-061 Stacker Motor down ON]. The Stacker Motor starts up.
Y N
Check the connections of P/J8847 and P/J8827. P/J8847 and
nected correctly.
Y N
Connect P/J8847 and P/J8827.
Check the wire between J8847 and J8827 for an open circuit or a short circuit (BSD 12.8
Flag 5). The wire between J8847 and J8827 is conducting without an open circuit or
a short circuit.
Y N
Repair the open circuit or short circuit.
