BATTERY PACK HANDLING PRECAUTIONS
WARNING! Battery Handling Precautions
The battery pack contains an internal safety fuse, but the user must take care to avoid short-
circuiting the contacts by preventing them from touching any metallic object. For example, the
battery pack should never be carried loose in a pocket where it could rub against coins, keys or
other metallic objects.
Short-circuiting the contacts of the battery pack will cause a heavy current to flow, which may
lead to excessive heating of the battery pack or any metallic objects connected to it. This could
cause burns, or start a fire.
WARNING! Do Not Try To Open The Battery Pack
The standard battery pack contains five Nickel-Metal-Hydride Cells. Exposing the cells
increases the risk of leakage or short-circuiting.
CAUTION: It is strongly recommended that the external charger is disconnected whenever the
battery pack is removed or replaced.
Please observe local standards for the handling, transport and disposal of Nickel-Metal-Hydride Cells.
BATTERY PACK CAPACITY
The printer is supplied with a 1.8Ah NiMH battery pack. This battery pack should be recharged while
installed in the printer which takes about 15 hours. The capacity of the battery pack when fully charged
will normally be sufficient to print normal text on about four full rolls of paper. However, the amount of
printing which can be achieved depends greatly on the printing density, idle time and other factors such
as the ambient temperature and the history of the battery pack.
With the printer awake but idle, a fully charged battery would last for up to 10 hours, but the built-in sleep
mode shuts down the printer completely, reducing energy consumption to a negligible rate.
In the event of the battery becoming exhausted, the printer will automatically protect its own control
circuitry by entering sleep mode if the instantaneous battery voltage drops below a threshold (e.g. during
a particularly heavy section of print). In this case data stored in the buffer are lost.
The battery pack should be capable of up to 500 complete charge and discharge cycles, though this may
be reduced in very repetitive applications. If a particular battery pack appears not to be holding charge as
well as expected, it may be worn out and should be replaced.
During battery charging the printer may become quite warm. This can crease the paper within the
mechanism. You may wish to feed out some paper before printing begins, either controlled from the host,
or by the user pressing the paper feed button.
