061-320 ROS Motor RAP
BSD-ON: 6.4/6.5
• The ROS Motor rotation speed does not reach the specified value within the specified
time after the ROS Motor started rotating.
• The light intensity of the LD1 does not reach the specified value.
Procedure
Check the connections of P/J401 on the MCU PWB and P/J140 on the ROS Unit. Connec-
tions are connected correctly.
Y N
Connect P/J401 and P/J140.
Check the connections of P/J219 and P/J618. P/J219 and
rectly.
Y N
Connect P/J219 and P/J618.
Check the wire between J401 and J140 for an open circuit or a short circuit (BSD 6.4 Flag 1/
Flag 2). The wire between J401 and J140 is conducting without an open circuit or a short
circuit.
Y N
Repair the open circuit or short circuit.
Check the wire between J401 and J130 for an open circuit or a short circuit (BSD 6.5 Flag 1).
The wire between J401 and J130 is conducting without an open circuit or a short circuit.
Y N
Repair the open circuit or short circuit.
Execute Component Control[061-200 ROS MOTOR ON]. The ROS Motor can be heard.
Y N
Measure the voltage between the MCU PWB P401-B7 (+) and GND (-) (BSD 6.5 Flag 2).
The voltage is +24VDC.
Y N
Measure the voltage between the MCU PWB P400-1 (+) and GND (-) (BSD 1.2 Flag
1). The voltage is +24VDC.
Y N
Measure the voltage between the Power Unit P526-4 (+) and GND (-) (BSD 1.2
Flag 1). The voltage is +24VDC.
Y N
Replace the Power Unit (PL 11.1).
Repair the open circuit between J526 and J400.
Replace the MCU PWB (PL 11.1).
Replace the ROS Unit (PL 3.1) If the problem persists, replace the MCU PWB (PL 11.1).
Install the Xero/Developer Cartridge securely.
Measure the voltage between the MCU PWB P401-B2 (+) and GND (-) (BSD 6.4). The
age is +5VDC.
