Interface Boards
Installing the interface board
This section describes how to install the optional interface boards
available for use with your LQ printer. Installation is easy, and the
only tool you need is a cross-head screwdriver.
High voltages are present inside the printer when the
power is on. Do not attempt to remove the cover unless
the minter is turned off and the power cord is unplugged.
Also, try not to touch contacts on the circuit board of the
printer because many of the components can be destroyed
by the static electricity that may build up on your body.

Turn off the power to the printer and the computer. Next,
unplug the power cord and disconnect the interface cable from
the printer.
Remove any installed printer options such as a pull tractor or
cut sheet feeder; then remove the printer cover, the paper guide,
and the platen knob.
Using a cross-head screwdriver, remove the two retaining screws:
one located at the front of the printer, the other at the back
near the printer’s fan.
