1
Turn off the printer power switch, and then unplug the printer. Disconnect the interface cable from
the printer.
Caution
Make sure you turn the printer OFF before you install or remove the SO-DIMM. Installing optional
accessories without turning off the printer could result in electric shock hazard.

Unscrew the two screws securing the back plate of the main controller board, and then pull out the
main controller board.

Unpack the SO-DIMM and hold it by the edges.
Caution
SO-DIMM boards can be damaged by even a small amount of static electricity. Do not touch the
memory chips or the board surface. Wear an antistatic wrist strap when you install or remove the
board. If you do not have an antistatic wrist strap, keep touching the bare metal on the printer.
4
Hold the SO-DIMM with your fingers on the side edges and align the notch in the SO-DIMM with the
protrusions in the SO-DIMM slot.

Put the SO-DIMM diagonally, and then tilt the SO-DIMM toward the main controller board until it
clicks into place.
To remove the SO-DIMM, open the retaining clips on both sides of the SO-DIMM by pushing them
outward, grasp both edges of the SO-DIMM and pull it out straight.
