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.Disconnect any interface cables from the printer.

3.Use a Phillips (cross-head) screwdriver to remove the two screws securing the interface cover; then lift off the cover. Be sure to keep both screws; you’ll need to use them again if you reinstall the cover.

4.Set any switches and jumpers on the board as described in the interface board’s manual. If your board has a jumper labeled JG, make sure that you set it to ON, or the board will not work properly.
