3.8.2 Printer Operation When an Error Occurs
The printer executes the following operations when detecting an error.
•
Stops all printer operations for the selected paper section.
•
Goes offline.
•
Goes BUSY. (See Section 3.3.3 DIP switches when DIP switch 2-1 is off.)
•
Flashes the ERROR LED.
3.8.3 Data Receive Error (only in the serial interface specification)
If one of the following errors occurs during serial interface communication, the printer prints "?" or
ignores the data, depending on the setting of DIP switch 1-1.
•
Parity error
•
