Paper out

CHAP. 4

TECHN…

When the “paper out” detector senses the end of the paper, the printer stops printing after printing a maximum of two more lines or on feeding the paper. The printer will set the DTR to “MARK” and set the printer to OFF LINE five seconds after a “paper out” condition is detected. To reset the printer after a “paper out”, load a new roll of paper into the printer and press the ON LINE switch to set the printer ON LINE.

Mechanical error

Mechanical error occurs when the motor locks or else and printing stops. After the error occurs, the printer outputs an X-OFF signal and stops printing. The printer sets the DTR signal to “MARK” and sets to “OFF LINE” five seconds after a mechanical error occurs. To reset the printer after a mechanical error occurs, close the top cover properly and press the “ON LINE” switch. If a buzzer sounds and the “ALARM” LED flashes at this point, locate the cause of the error and turn the power off and then back on to reset the printer.
