Recommendation ■ If you are using a serial interface, make sure that the slide switch of the serial interface is in the correct position. Make sure that the interface settings have been properly set up in the INTERFACE menu using the control panel. ■ This problem is usually related to serial interface settings. Your computer is not recognizing the printer input buffer's full signal.
