Precautions when installing accessories

Disconnect the power cord:

Never remove the control board cover while the printer is plugged in.

To avoid the possibility of an electrical shock, always disconnect the power cord when installing or removing ANY internal or external accessories.

Discharge static electricity:

The control board and internal accessories (network interface card, DIMM, and hard disk) are sensitive to static electricity. Before installing or removing internal accessories, 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 round before finishing installation, discharge any static electricity once again.

Installing a dual in-line memory module (DIMM)

Your printer has a dual in-line memory module (DIMM) slot. Use this DIMM slot to install additional memory.

Your printer has 128 MB of memory which can be expanded to 512 MB. For information about ordering optional DIMMs, see page 7.1.
