TROUBLE SHOOTING
Description
An abnormal load is applied to the CR motor.
Some abnormalities were found in the encoder test result.
An abnormal load is applied to the PF motor.
The condition to stop the PF motor is not satisfied when the PF
motor has driven for a predetermined time period.

Some abnormalities were found in the encoder test result.
The positioning error detected by the PF encoder fell outside the
specified limits.
Remedies for Service Call Error
Remedy
Check the carriage shaft surface for any foreign matters, and
remove it if any.
Check that the carriage shaft and the contact points between the
carriage unit and the main frame are properly lubricated.
