3. ERROR INDICATIONS
This machine includes a self-diagnosis function. If the machine 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 personnel to quickly find out the problem.
3.1 Error Codes
Errors in shaded column do not usually occur during normal use. The possible causes are
noise around the installation site, fluctuation of the power supply voltage, and failures in the
software.
