Using Optional Interfaces

5. Slide the interface board along the slots on both sides of the
compartment. Push it in firmly to fully insert the board’s
connector into the printer’s internal socket.
6. Secure the interface board in the slot with the two screws
included with the board.
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 parallel
interface.
If you are using more than one computer, reconnect the
other interface cable as well.
8. Make sure the printer is turned off. Then plug in the power
cord.
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. See page D-8 for instructions.
To remove the interface board, 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.
