General Precautions - Brother MPRINT MW-145MFi Product Safety Manual

Rechargeable Li-ion battery
 At the time of purchase, the rechargeable battery is slightly charged so
that the operation of the printer can be verified; however, before you use
the printer for the first time, you must fully charge the battery using the AC
adapter.
 If you do not intend to use the printer for a long period of time, remove the
rechargeable battery from the printer, and then store it in a location where
it is not exposed to static electricity, high temperatures, or high humidity
(temperatures between 15C/59F and 25C/77F and humidity between
40% and 60% are recommended). To maintain the efficiency and life of
the rechargeable battery, charge it at least once every three months.
Printer
 DO NOT cover or insert any foreign objects into the paper outlet, power
connector or USB port.
 DO NOT use paint thinner, benzene, alcohol, or any other organic solvent
to clean the printer. Doing so may damage the casing finish. Use a soft,
dry cloth to clean the printer.
 When using optional accessories, read the relevant instruction manuals,
and use them correctly.
 This printer uses thermal paper. If the printed paper is marked with ink, for
example, written on or stamped, the ink may cause the printed text to fade
or become discolored. In addition, the applied ink may take some time to
dry.
 DO NOT touch the printer with wet hands.
