Smart Battery:  PA-BT-006

The smart battery tracks each individual battery’s use and reports the estimated life of the battery using the printer display.  Upon power-up of the printer will display a message describing the life status of the battery as excellent, great, poor, and very poor. During normal operation the estimated life is displayed in 25% increments in the form of vertical dots.


Battery Charger:  PA-BC-003

The battery charger charges and individual battery outside of the printer, by simply dropping it in and latching into the charger.  It is powered by the same power adapter used to charge the battery while in the printer. The charger is also expandable up to four chargers using a single power adapter.  The chargers individually interlock making them a single unit.  Power is interconnected using a short power cable between each charger that is hidden under the chargers. The chargers can also be wall mounted to save counter space.  See the detailed instructions included with the battery charger for proper use and mounting.


Roll Holder Stop

The roll holder stop is a simple adhesive tab that prevents the roll holder from closing.  It is ideal for minimizing the distance you must expand the roll holder when loading the media roll.  Install the roll holder stop at a width slightly less than the width of your media.  Do not use the roll holder stop if you intend to use narrower media, because it will prevent the roll holders from holding the narrower roll. The roll holder stop is included with the printer.


Belt Clip

The belt clip allows you to carry the printer on your belt.  It easily installs on the printer by snapping on the metal bar located on the top backside of the printer and it simply slides on and clips onto your belt. The belt clip is included with the printer.


USB Strain Relief Clip

The USB strain relief clip prevents the USB cable from being pulled out of the printer and reduces the chance of damaging the printer’s USB connector.  It is ideally used when the printer is tethered to the host using a USB cable.  The Brother adapter cable (p/n: US8002501) is needed to use the USB strain relief clip.  To use it you install the adapter cable, install the clip and install the securing screw.
