Using Optional Interfaces
7. Connect the proper interface cable to the interface board
and to your computer. If the cable has a grounding wire,
connect it to one of the screws securing the interface board.
8. Reconnect any other interface cables you disconnected.
9. Make sure the printer is turned off. Then plug in the power
cord and turn on the printer.
In most cases, the printer automatically detects the interface
you're using. However, if you have trouble printing through an
installed interface board, you may need to change the printer's
I/F (interface) mode setting using default-setting mode. See
page 5-3 for instructions.
To remove the interface board, first follow steps 1 and 2 in this
section. Remove the screws securing the board and carefully
pull it out of the internal printer socket. Then replace the
interface cover and screws you removed in step 3. Now you can
connect your printer using one of the built-in interfaces as
described in your Quick Setup booklet.
