2. LIST OF ERROR DISPLAY / INDICATION

1-5

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 in text and by icon.

2) In printing from a computer, warnings 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.

- ON/OFF button:

The machine is turned off.

- OK button:

After an error is cleared, the machine recovers. With some operator call errors, the error is automatically cleared when the error cause is corrected, so the OK button is not necessary to be pressed.

- Stop/Reset button:

The job at an operator call error is cancelled to clear the error.
