Caution:

To avoid damaging your printer or computer, do not install the interface board when the printer is connected to an electrical outlet.

Using Optional Interfaces

Installing Optional Interfaces

Before you install an optional interface board in your printer, make sure the printer is turned off and all the printer’s lights are off. Then follow these steps:

1.Unplug the power cord from the electrical outlet (and from the back of the printer, if your printer’s power cord is removable).

2.Turn the printer around so that its back faces you, and disconnect any interface cables.

3.Use a cross-head screwdriver to remove the two screws securing the shield plate to the interface slot; then lift off the plate. Be sure to keep both screws; you may need to use them again when you reinstall the shield plate.

4.Be sure to set any switches and jumpers on the board. See the interface board’s manual for details. If your board has a jumper labeled JG, make sure that you set it to on, or the board will not work properly.
