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 options (Memory and PS
DIMMs, Network cards) 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.
