Precautions
Disconnect The Power Cord
Never remove the printer control board while the printer is plugged in.
To avoid the possibility of electrical shock, always disconnect the power cord when installing or removing ANY internal or external printer option.
Discharge Static Electricity
The control board and internal printer options
(SIMM, Network interface) are sensitive to static electricity. Before installing or removing an internal option, 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 the installation, discharge any static electricity again.
