Testing the Card
Run a self test on the card if the printer is not working
normally, or if the interface cannot be connected to
determine if the card is functioning normally.
When you run the self test, the printer prints the
current card settings and the data from addresses
<30>H to <39>H.
Follow these steps to run a self test:
1. Switch off the printer power and remove the
power plug from the socket.
2. If an interface cable is connected to the printer,
disconnect it.
3. Remove the interface card from the printer. Refer
to the printer manual for details.
4. Set DIP switch 9 on the card’s circuit board to ON.
5. Reconnect the interface card to the printer. See
your printer manual for details.
6. Load paper in the printer.
7. Plug in the power cable and switch the power on
to start the self test.
8. Switch off the power and remove the power plug
from the socket when self test is complete.
