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 messages are
displayed by the printer driver Status Monitor.
2. 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:
