Errors and warnings are displayed by the following ways:
- Operator call errors are indicated by the Alarm lamp lit in orange, and the error and its solution
are displayed on the LCD.
- Messages during printing from a computer are displayed on the printer driver Status Monitor.
- Error codes are printed in the "operator call/service call error record" area in EEPROM
information print.
1-1. Operator Call Errors (Alarm Lamp Lit In Orange)
Buttons valid when an operator call error occurs:
- ON button: To turn the printer off and on again.
- 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.
- Stop button: To cancel the job at error occurrence, and to clear the error.
