Step 1: Install the HP Jetdirect print server
CAUTION The HP Jetdirect print server contains electronic components that
can be damaged by static electricity. To prevent buildup of static
electricity, maintain frequent contact with any bare sheet metal
surface on the printer. If possible, wear a grounding wrist strap
(or similar device). Handle the print server carefully at all times.
Avoid touching electronic components or circuit paths.
1 Press and hold (power button) to turn off the printer, and then
unplug the power cord.

cover again.
3 Firmly insert the HP Jetdirect print server into the EIO slot.
4 Insert and tighten the retaining screws that came with the
HP Jetdirect print server.
5 Connect the network cable to the HP Jetdirect print server.
