The Tray 5 Stack Down Sensor failed to change state within 3 seconds after the Tray 5 Feed/
Lift Motor Down was energized.
Initial Actions
• Refer to BSD 7.9 and BSD 7.10 for the following procedure.
• Ensure the Tray 5 top cover is closed.
• Ensure there is paper loaded in the Tray 5.
• Ensure connector P/J416A on the IOT Drive PWB is properly seated
• Check for crimped or broken wires to connectors on the IOT Drive PWB
Procedure
Cheat the Tray 5 Switch. Enter dC330 008-226 Tray 5 (Bypass) Level up Sensor. Press
Start. Manually actuate the Tray 5 Stack Up Sensor. The display changed from H to L.
Y N
+0 VDC is measured at P/J416B-6 on the IOT Drive PWB.
Y N
+5 VDC is measured at P/J145-2 on the Tray 5 Stack Up Sensor.
Y N
Go to Flag 2 on BSD 7.9 and check the harness and connectors. If the harness
and connectors are OK, replace the IOT Drive PWB.
