TROUBLE SHOOTING
Table 2-2. Service Call Error
Cause
The number of occurrences of reversing the
PRESSURE ROLLER MOTOR has reached a
predetermined limit.
The polarity of PRESSURE ROLLER MOTOR
encoder cable is opposite.
The polarity of PRESSURE ROLLER MOTOR
cable is opposite.
Abnormally-long driving duration of the
PRESSURE ROLLER MOTOR was detected.
Irregular load
Firmware becomes out of control.
The PRESSURE ROLLER MOTOR was driven at
a speed abnormally faster than a predetermined one
during acceleration or deceleration.
Irregular load
PRESSURE ROLLER MOTOR encoder failure
PRESSURE ROLLER MOTOR failure
PRESSURE ROLLER MOTOR driver failure
The PRESSURE ROLLER MOTOR was driven at
a speed abnormally slower than a predetermined
one during operation.
Irregular load
PRESSURE ROLLER MOTOR encoder failure
PRESSURE ROLLER MOTOR failure
TBD
TBD
The control terminal (Vre terminal) of the cutter
motor driver has shorted out.
TBD
Remedies for Service Call Error
Check Item
1. Is there any problems such as damaged cable in the
connections below?
PRESSURE ROLLER MOTOR (PRESSURE
ROLLER MOTOR encoder cable) to SUB-B
BOARD (CN5)
2. Does the PRESSURE ROLLER SENSOR work
properly? Check it using the Service Program.
