Installing Optional Interfaces - Epson 800 User Manual

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

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.
