Imaging unit error
LSU motor does not operate.
After LD on, the Laser beam detect
signal is not occurred or irregular.
LSU motor does not operate or the
drive signal is abnormal.
Yellow LSU motor does not operate. Check the LSU motor noise. If there is any
Suggested Solutions
1. Check the Thermostat. If it is defective,
replace it.
2. Check the Lamp. If it is defective, replace it.
3. Check the fuser connector. Reconnect it.
4. If the Heat On signal is not occurred from
Power supply, replace it.
Replace the Fuser/Fuser control board/Engine
controller
1. Turn off the power. And reconnect the
connector of the Hard disk.
2. If the error message is still displayed,
replace the Hard disk.
3. If the problem persists, replace the main
board.
1. Check the T/C sensor Harness connection.
2. Check the output wave form of the T/C
sensor.
3. Check the Engine B/D TC Sensor ADC
Check the LSU motor noise. If there is any
dirving noise, check the motor signal.
1. Check the Beam Detecht signal. If there is
a BD signal, replace the Main board. If or
not, check the LD contol signal.
2. Check the LD Power is normal.
3. If it is normal, check the light receving part.
Check the LSU motor noise. If there is any
dirving noise, check the motor ready signal.
dirving noise, check the motor signal.
