1-2. Operator Call Error (Alarm LED Lit In Orange) Troubleshooting

Errors and warnings are displayed by the following ways:

- Operator call errors are indicated by the Alarm LED lit in orange, and messages are displayed on the printer driver Status Monitor.

- Error codes (the latest 10 error codes at the maximum) are printed in the "operator call/service call error record" area in EEPROM information print.

Buttons valid when an operator call error occurs:

- ON button: To turn the printer off and on again.

- Resume/Cancel button: To cancel the job at error occurrence, and to clear the error.
