Precautions		The LN17 printer options are easy to install. Installing and
		testing any one option is likely to take 5 to 15 minutes.
		Before installing or removing any printer option, take the
		precautionary steps outlined below.
		POWER OFF THE PRINTER: The printer determines which
		options are installed through a self-test. The self-test is run
		when you power ON the printer. Therefore, for proper
	Caution	operation, you must power OFF the printer before installing/
		removing an option, then power it back ON after installing/
		removing an option.
		DISCONNECT THE POWER CORD: Never remove the printer
		controller board while the printer is plugged in.
	Caution	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 controller board and
		internal printer options (SIMMs, network interface cards, and
		the hard drive) are sensitive to static electricity. Before
	Caution	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 around before finishing
		the installation, again discharge any static electricity.
