077-309 Left Hand Low Interlock Open RAP
BSD-ON:1.4
The L/H Lower Cover is open.
Procedure
Check opening/closing of the Left Lower Back Cover. The Cover can be opened/closed.
Y N
Reinstall the Left Lower Back Cover (PL 2.6).
Check the installation of the LHL Switch. The LHL Lower Cover Interlock Switch is
installed correctly.
Y N
Install the LHL Lower Cover Interlock Switch correctly.
Execute Component Control [077-301 LHL Lower Cover Interlock Switch]. Open/close the L/H
Lower Cover. The display changes.
Y N
Check the connections between the MCU PWB and the LHL Interlock Switch (BSD 1.4).
Connectors are connected correctly.
Y N
Connect the connectors
Check the wire between J424B on the MCU PWB and the J119 on the LHL 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.
Y N
Repair the open circuit or short circuit.
Check the conductivity of the LHL Interlock Switch (PL 2.6) between J119 and J424B
(BSD 1.4). The wire are connecting successfully when the LHH Interlock Switch is
closed.
Y N
Replace the LHH Interlock Switch (PL 8.4).
Measure the voltage between the MCU PWBJ422B-10 (+) and GND (-) (BSD 1.4). The
voltage is approx. +24VDC.
Y N
Replace the MCU PWB (PL 11.1).
Measure the voltage between the LHL Interlock Switch J119-2 (+) and GND (-) (BSD
1.4). The voltage is approx. +24VDC.
Y N
Check the wire between J422B and J119 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 LHL Interlock Switch J119-1 (+) and GND (-) (BSD
1.4). The voltage is approx. +24VDC.
Y N
Replace the LHL Interlock Switch (PL 8.4).

077-309
A B
Measure the voltage between the MCU PWB J422B-9 (+) and GND (-) (BSD 1.4). The
voltage is approx. +24VDC.
Y N
Check the wire between J119 and J422B and the Terminal Block for an open circuit
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.
