Precautions When Installing Printer Options
DISCONNECT THE POWER CORD:
Never remove the printer control board 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 printer option.
DISCHARGE STATIC ELECTRICITY:
The control board and internal printer option (Memory) 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
installation, discharge any static electricity once again.
