out”, load paper into the printer and press the “ON LINE” switch to set the printer to “ON LINE”.

Mechanical error

Mechanical errors are detected when the motor locks or else and the unit will not print. Immediately after a mechanical error occurs, the printer sets the DTR to “MARK” and then sets the printer to “OFF LINE”. To cancel a mechanical error, close the front cover properly and press the “ON LINE” switch. If the buzzer sounds and the “ALARM” LED flashes at this time, then locate the cause of the error and turn the power for the printer off and back on again to reset the printer.

Framing error

A framing error occurs when “SPACE” is detected at the stop bit. When a framing error or a vertical parity error occurs for the data which is received, the printer prints out a “?” mark to indicate that the error occurred.

When pin 6 of the peripheral unit drive circuit connector is set “HIGH”, status bit 7 becomes “1”.

X-ON/X-OFF Mode

This mode is accessed when the DIP switch 1-5 is OFF. If printer errors do not occur after the power is turned on, the printer outputs an X-ON (DC1 by control code; 11H by hexadecimal data) signal on the TXD signal line of the printer which sends it to the host computer. When the host computer receives the X-ON signal, the host computer transmits the data to the RXD signal line of the printer. If data text is not sent from the host computer (even after transmitting the X-ON signal to the host computer), the printer outputs an X-ON signal at 3 second intervals until the printer receives data. The printer starts outputting an X-OFF (DC3, 13H) signal when the empty space in the buffer reduces below 256 bytes. When the host computer receives the X-OFF signal, it halts output of data (however, the printer can continue receiving data until the buffer becomes
