Error Messages
Whenever the printer detects an error condition. the Error Indicator will either flash or go to a steady on
condition. The indicator flashes for errors that can be easily corrected such as Check Paper or Paper Door
Open.
The indicator will stay on without flashing for errors that cannot be recovered without loss of data. These are
typically caused by interface configuration errors such as serial handshaking, or baud rate, and will require that
the printer be turned off to clear the error.
