SC129 - Scanner Motor Overload
Definition:
The motor control PCB detects a large current (2 A) of the scanner drive
motor power for more than 0.2 seconds.
Points to check:
•
Mechanical interference with the scanner
•
Scanner drive motor
•
DC motor drive PCB (Fuse: F1)
•
Motor control PCB
SC130 - Motor Control Interface Malfunction
Definition:
At power on, the main PCB cannot communicate with the motor control PCB
through the serial interface lines.
Points to check:
•
Interface lines (CN111 on the main PCB)
•
External noise
•
Motor control PCB
SC142 - Lens Vertical Drive Failure
Definition:
The motor control PCB cannot detect the lens vertical home position sensor
signal or vertical drive encoder signal.
Points to check:
•
Mechanical interference with the lens vertical drive
•
Lens vertical drive motor
•
Lens vertical home position sensor
•
Lens vertical drive encoder sensor
•
Motor control PCB
•
DC motor drive PCB (Fuse: F4)
