Important safety instructions

Rechargeable Li-ion battery (The rechargeable Li-ion battery comes with the RJ-3050/3150. Li-ion
battery optional with the RJ-4030/4030Ai/4040.)
Carefully observe the following precautions for the rechargeable Li-ion battery (hereafter referred
to as "rechargeable battery"). If these precautions are not followed, overheating, leaking, or cracks
in the battery may result in an electrical short, explosion, smoke, fire, electric shock, injury to
yourself or others, or damage to the product or other property.
Use the rechargeable battery only for its intended purpose. The printer and rechargeable battery

are designed to function exclusively with each other. DO NOT insert the rechargeable battery
into a different printer, or a different rechargeable battery into your printer, otherwise fire or
damage may result.
 To charge the rechargeable battery, insert it into the printer, and then use the AC adapter
designed specifically for this printer.
DO NOT charge the rechargeable battery near a fire or in direct sunlight. This could activate the

protection circuitry, which is designed to prevent danger from high heat. Activation of the
protection circuitry could cause charging to stop, charging to occur with excessive
current/voltage if the protection circuitry fails, or an abnormal chemical reaction within the
battery.
 When charging the rechargeable battery, use only a battery charger designed specifically for the
rechargeable battery.
 DO NOT allow wires or other metal objects to come into contact with the terminals of the
rechargeable battery. DO NOT carry or store the rechargeable battery with metal objects such
as necklaces or hairpins. This could cause an electrical short, and lead metal objects such as
wires, necklaces, or hairpins to overheat.
 DO NOT use or leave the rechargeable battery near fire, heaters, or other high temperature
(above 176F/80C) locations.
 DO NOT allow the rechargeable battery to come into contact with or to be immersed in water.
 DO NOT use the rechargeable battery in corrosive environments, such as areas where salty air,
salt water, acids, alkalis, corrosive gases, chemicals, or any corrosive liquid are present.
 DO NOT use the rechargeable battery if it is damaged or leaking.
DO NOT directly solder any connections to the rechargeable battery. This could cause internal

insulation to melt, gas to be emitted, or safety mechanisms to fail.
 DO NOT use the rechargeable battery with the polarity (+) (-) reversed. Check the orientation of
the rechargeable battery before inserting it, and do not try to force the rechargeable battery into
the printer. Charging the rechargeable battery with the polarity reversed could cause an
abnormal chemical reaction within the rechargeable battery or abnormal current flow during
discharge.
 DO NOT directly connect the rechargeable battery to a household electrical supply.
