CHAPTER 13 TROUBLESHOOTING
E010
A specific revolution is not detected from the main motor rotation detection
signal (MLOK*), causing the signal to go '1'. (main motor fault)
Possible cause The main motor (M101) is faulty. The controller PCB is faulty.
Remedy
1) Connector
NO : Correct the connection.
2) Main motor (M101), DC controller PCB
YES : Replace the main motor.
NO : Check the wiring; if normal, replace the DC controller PCB.
E100
When the scanner motor is started up, the BD input signal does not arrive
within a specific period of time.
When the scanner motor is started up, the motor rotation is too fast, and
fails to reach a specific revolution within 20 sec at time of deceleration.
While the scanner motor is rotating at a specific speed, the BD input signal
cycle is not within a specific range (±2%) for an equivalent of 10 mm (print
distance).
While the scanner motor is rotating at a specific speed, the BD input signal
cycle is not as indicated (±2%).
During the WMUPR period after the power switch has been turned on or
the front cover/left cover has been opened/closed, the drum unit is absent.
Possible cause The wiring is faulty (short circuit, open circuit). The laser scanner unit is
faulty. The DC controller PCB is faulty. The drum unit is not installed.
Remedy
1) Drum unit
NO : Install the drum unit.
2) Connection
NO : Correct the connection.
3) Laser/scanner unit, DC controller PCB
YES : End.
NO : Replace the DC controller PCB.
13-120
Is the connection of the connector (J903) of the main motor and the
connector (J06) on the DC controller PCB normal?
Try replacing the main motor. Is the fault corrected?
Is the drum unit installed in host machine?
Is the connection of the connector (J908) on the BD detection PCB,
connector (J907) of the laser unit, and connector (J102) on the DC
controller PCB normal?
Try replacing the laser/scanner unit. Is the fault corrected?
