TROUBLE SHOOTING
Description
The home position of the carriage unit is not detected.
When releasing the driven roller, the Roller Release HP Sensor cannot
detect the change of status.
During PG operation, the PG HP Sensor cannot detect the change of
status.
Abnormal Cutter operation is detected.
Slipping of the teeth of the timing belt.
Slack of the timing belt.
Abnormality of the cutter sensor.
During detection of paper thickness, the thickness cannot be determined
because chattering occurs.
At power-on, the paper thickness sensor detects more than 2.2 mm
paper thickness.
Due to the leak of AID current, the specified voltage cannot be
achieved.
Firmware supporting the current version AID board is not installed.
The temperature of the Head Driver rises, and reaches the specified
level.
