General Precautions
Rechargeable Li-ion battery (Optional)
 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 the printer will not be used 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 humidity, or high 
temperatures (temperatures between 15 and 25°C and humidity between 40 and 60% are 
recommended). To maintain the efficiency and life of the rechargeable battery, charge it at least every 
six months.
 If you notice anything unusual about the rechargeable battery the first time it is used, for example 
overheating or rust, STOP using the battery. Contact Brother customer service.
Printer
 DO NOT cover or insert foreign objects into the paper outlet, AC/DC 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, use them as described in their instruction manuals.
 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 discoloured. In addition, the applied ink 
may take some time to dry. Printed text may fade or become discoloured if the label comes into contact 
with any of the following: vinyl chloride products; leather goods, such as wallets and purses; organic 
compounds, such as alcohol, ketones, or esters; adhesive tape; erasers; rubber mats; magic marker 
ink; permanent marker ink; correction fluid; carbon; glue; diazo sensitized paper; hand lotion; hair care 
products; cosmetics; water or sweat.
 DO NOT touch the printer with wet hands.
 DO NOT use folded, wet or damp paper, otherwise a paper misfeed or a malfunction may occur.
 DO NOT touch paper or labels with wet hands, otherwise a malfunction may occur.
 DO NOT leave the release cover open in high-temperature environments. The cover could become 
deformed, causing the paper to jam.
