Installing additional memory

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.

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.
