2.Start and end of self diagnostic print

Set the power on while pressing the FEED switch and release the FEED switch after the printer mechanism activates to start self-printing.

The self diagnostic print automatically ends when a preset number of characters are finished printing. While printing, the printer is in Off-line mode.

4.1.4No paper sensor

No paper sensor is mounted on the paper path in the printer mechanism.

It detects no paper status of the roll paper. When detecting no paper status, the printer sends PE signal to the host and stop printing. Pay special attention to the end of roll paper. The end should not be glued to the core of the roll. If no paper status is detected, replace the roll paper.

POWER OFF , /INIT

When the above errors are detected except transmission error and paper low end error, printer stops all operations and outputs error signal.

In the case of parallel interface: Error signal becomes “LOW”

In the case of serial interface:

Error signal becomes “LOW” and error bit in the status information is set to “ON”.

2) Return to normal status from error statuses

Remove causes of error statuses and turn the power on again or input the /INIT signal to return to normal. When this process is activated, at the time of power switch turned off, the printer will be initialized, so that settings are required again.

If data remains in the buffer, attention should be paid

4.3 Buffer full print

If there remains data in the buffer after one line of data is received, printer automatically prints preceding data. The volume of buffer full data varies depending on ASCII characters or bit images.
