Installing an interface card
Note:
If you install an optional interface curd, make sure your printer’s DIP switches are set for parallel interface, even if you are installing a serial interface card.
1.Turn off both your printer and your computer. Then remove all power and interface cables from the printer.
2.Turn your printer so that the rear cover faces you.
3.Open the printer’s rear cover.
4.Be sure to set any switches and jumpers on the card, as necessary. See the interface cards manual for details. Make sure that you set jumper JG to on, or the card will not work properly. (To set the jumper to on, cover both wires of the terminal with the rectangular jumper plug.)
