ERROR INDICATIONS

This printer includes a self-diagnosis function. If the printer does not work normally it judges
that an error has occurred, and indicates the corresponding error message on the LCD, which
in turn helps the service men to quickly find out the problem.

Error Codes

The errors with a mesh background in the table below do not occur in the normal operation.
They might occur due to noise around the installation site, change of the power supply
voltage, and failures in the software.
