Sensor Troubleshooting Procedure (S6 – S10, S12 – S15):
1. Do GP 6.3.2 SENSORS Procedure. Check to make sure all sensors
show "0" on the LCD when uncovered and "1" when covered.
If any sensor shows "1" when uncovered, clean that sensor. Also
check if there is any obstacle in the sensor window.
All sensors show "0" when uncovered and "1" when covered
Yes- Return to the RAP that directed you here.
No- Go to Step 2
2. Make sure the sensor cable is connected securely at the Sensor and
at the Main Control Board (PL 5.27). Do REP 1.5 to remove the Rear
Cover to gain access to the connector at the Control Board. Refer
to GP 6.22 and Section 7 for additional info regarding the connector
locations.
All the connections are made securely
Yes- Go to Step 3
No- Make the connection and repeat Step 1.
3. Light from sensor components can be viewed with a cell phone
camera, if the sensor is working you will be able to see a bright light.
Alternately a small mirror can be used. Use this procedure to check
that each sensor is emitting a beam of light during operation.
CAUTION: Sensor emits High Intensity narrow angle Infrared
beam (940nm). It is invisible to naked eye, avoid looking directly
at the sensor when the machine is powered ON. See Section 0,
page ix for other languages.
There is no light from any of the sensors on the Sensor Board
Yes- Go to Step 4
There is no light from some of the sensors on the Sensor Board
Yes- Go to Step 5
There is a bright light from all the sensors
Yes- Go to Step 6
4. Replace the sensor board- REP 2.14 for S6-S10 or REP 2.15 for
S12-S15
This clears the fault
Yes- Resume normal operation
No- Go to Step 5
General Procedures and Information
