077-308 Left Hand High Interlock Open RAP
BSD-ON:1.4
The L/H-H Cover is open.
Procedure
Check opening/closing of the IOT L/H-H Cover. The IOT L/H-H Cover can be opened/
closed.
YN
Reinstall the IOT L/H-H Cover.
Check the installation of the Exit 2 Interlock Switch. The Exit 2 Interlock Switch is installed
correctly.
YN
Install the Exit 2 Interlock Switch correctly.
Execute Component Control [077-302 LHH Interlock Switch]. Open/close the IOT L/H-H
Cover.
The display changes.
YN
Check the connections between the MCU PWB and the LHH Interlock (BSD 1.4). Con-
nectors are connected correctly.
YN
Connect the connectors
Check the wire between J422B on the MCU PWB and the J116 on the LHH Interlock
Switch for an open circuit or a short circuit (BSD 1.4).
The wire are conducting without
an open circuit or a short circuit.
YN
Repair the open circuit or short circuit.
Check the conductivity of the LHH Interlock Switch (PL 8.4) between J116 and J442B
(BSD 1.4).
The wire are connecting successfully when the LHH Interlock Switch is
closed.
YN
Replace the LHH Interlock Switch (PL 8.4).
Measure the voltage between the MCU PWBJ422B-8 (+) and GND (-) (BSD 1.4). The
voltage is approx. +5VDC.
YN
Replace the MCU PWB (PL 11.1).
Measure the voltage between the LHH Interlock Switch J116-1 (+) and GND (-) (BSD
1.4).
The voltage is approx. +5VDC.
YN
Check the wire between J422B and J116 Terminal Block P/J606 for an open circuit
or a short circuit (BSD 1.4). Repair or replace as required.
Measure the voltage between the LHH Interlock Switch J116-2 (+) and GND (-) (BSD
1.4).
The voltage is approx. +5VDC.
YN
Replace the LHH Interlock Switch (PL 8.4).
Measure the voltage between the DET Face Up Tray Switch J115-2 (+) and GND (-) (BSD
1.4).
The voltage is approx. +5VDC.
YN
Check the wire between J115 and J116 and the Terminal Block for an open circuit or
a short circuit (BSD 1.4). Repair or replace as required.
Measure the voltage between the DET Face Up Tray Switch J115-1 (+) and GND (-) (BSD
1.4).
The voltage is approx. +5VDC.
YN
Replace the DET Face Up Tray Switch (PL 8.4).
Measure the voltage between the MCU PWB J422B-6 (+) and GND (-) (BSD 1.4). The
voltage is approx. +5VDC.
YN
Check the wire between J116 and J422B-6 and the Terminal Block for an open cir-
cuit or a short circuit (BSD 1.4). Repair or replace as required.
Check for an intermittent Interlock Switch (BSD 1.4).
Check the paper transport drives and repair as required.
