First, Prepare the Printer

1. Turn off the printer, remove the power cord from the rear

the side and back corner where the cable port is located.
Make sure that you have enough room to work.

screws from the Interface Panel (expansion slot) on the
rear of the printer (B), and pull out the Controller Board.
3. Remove the screw that holds the small 1.5" x 3.75" plate
over the Network Slot. Remove the plate. Keep the screw
