4.1.1 Precautions

Before proceeding with any disassembly or assembly work, make absolutely sure of the following.

WARNING	„ The power switch for Stylus Pro 7600/9600 is incorporated in
	the secondary circuit of the power supply circuit. Therefore, the
	printer is always supplied with electric power, unless the power
	cable is disconnected. Before servicing, unless otherwise stated,
	be sure to unplug the power cord from the wall outlet to
	prevent injury, burn, and electric shocks or damage to the
	circuit. In doing so, be sure to turn the printer off and wait
	several seconds first and then unplug the power cord. If you
	must keep the power supplied to measure voltage, be aware of
	the potential for electrical shock and do all tasks with the most
	care.
	„ With the front cover open, the cover sensor stops the operation
	of the CR motor and PF motor. To ensure safety, you are
	prohibited from disabling this interlock function.
	„ A lithium battery for memory backup is installed on the main
	circuit board of Stylus Pro 7600/9600. To prevent accidents
	caused by the battery, never fail to observe the following
	instructions when serving the main circuit board:
	• Keep the battery away from any metal or other batteries so
	that electrodes of the opposite polarity do not come in
	contact with each other.
	• Do not solder on any part of the battery. (Doing so may result
	in leakage of electrolyte from the battery, burning or
	explosion. The leakage may affect other devices close to the
	battery.)
	• Do not charge the battery. (This may cause burning or
	explosion.)
	• Do not dismantle the battery. (The gas inside the battery may
	hurt your throat. Leakage, burning or explosion may also be
	caused.)
	• Do not short-circuit the terminals of the battery. Do not put
	the battery on a conductive table in such a way that the
	terminal face comes in contact with the table.
	• Do not remove and install the battery. Do not install the
	battery in the wrong direction.
	• Do not heat the battery or put it near fire.
