Caution
The controller and PostScript boards are sensitive to static
electricity. Before installing the PostScript board, discharge static
electricity from your body by touching something metal, such as the
metal back plate on any device plugged into a grounded power
source. If you walk around before finishing the installation, again
discharge any static electricity.
Never remove the printer controller board while the printer is
plugged in.
1 Power OFF the printer and disconnect all cables from the back of the printer.
2 Unscrew the outside pair of retaining screws
holding the controller board in place. Keep the
screws in a safe place. 3 Carefully slide out the controller board.
Set the controller board down on a safe, level
surface.
