Machine Error - Star Micronics DP8340 Series User Manual

Paper Empty
When the paper out detector indicates end of paper, the printer stops printing
after a maximum of two lines of printing or paper feed. The host computer can
receive the printer status by transmitting an ENQ code to the printer. The printer
goes OFF LINE and sets the DTR to "MARK" status in 5 seconds after occur-
rence of a paper empty. It is necessary to install paper into the printer and press
the ON LINE BUTTON to light the ON LINE LAMP in order to recover from
paper empty status.

Machine Error

A machine error may be generated by paper jamming or when the printer is un-
able to print data. When a machine error occurs the printer stops printing. In the
X-ON/X-OFF mode, the printer outputs an X-OFF signal immediately. At this
time the host computer can receive the printer status after transmitting an ENQ
code to printer. The printer goes OFF LINE and sets the DTR to "MARK" status
within 5 seconds after the occurrence of Machine Error. It is necessary to turn
the printer power off and on again in order to recover from Machine Error.
