4.1.4 Paper sensor
The printer has a paper sensor located at each paper passing through section on the printer
mechanism to monitor no paper status. Once no paper status is monitored, it sends PE
signal to stop printing. Load paper once no paper status is found.

If any error stated above is detected, except communication error and paper near-end,
all operations stop and printer outputs /ERROR signal.
For parallel, /ERROR signal is changed to “L”.
For serial, /ERROR signal is changed to “L”.
Error bit of status information is set ON.
2) Return to normal status from error status
Remove causes of error status 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, it will be cleared. 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.
