1. LIST OF ERROR DISPLAY / TROUBLESHOOTING
1-1. Operator Call Errors
Errors and warnings are displayed by the following ways:
1. Operator call errors are indicated by the Alarm LED lit in orange, and the error and its solution are
displayed on the LCD.
2. Messages during printing from a computer are displayed on the MP driver Status Monitor.
3. Error codes are printed in the "operator call/service call error record" area in EEPROM information
Print
Buttons valid when an operator call error occurs:
1. ON/OFF button: To turn the machine off and on again.
2. OK button: To clear and recover from an error. In some operator call errors, the error will automatically
be cleared when the cause of the error is eliminated, and pressing the OK button may not be necessary.
3. Stop/Reset button: To cancel the job at error occurrence, and to clear the error.
