Daily Operation
Battery Charging The MtP300 contains battery monitoring and charging circuitry so that the battery may be charged while still in
the printer. Charging the battery in the printer requires an optional power supply. Printek offers power supplies
for use with 100-240VAC/50-60Hz and 12/24VDC for vehicle applications.
Optional external battery chargers are also available so that you can have fully charged batteries “standing by”
when needed.
The printer’s battery status is displayed in the lower right corner of the front panel LCD Display. The status is
displayed as a battery shape which indicates the relative capacity that remains as indicated below.
Fully Charged Discharged
To charge the battery inside the MtP300, connect the power supply to the appropriate source, and connect the
output of the supply to the printer’s power connector shown in Figure 7.
Caution: Use only Printek power supplies to power your printer and charge batteries. Other power supplies
may damage the electronics and printing mechanism. Damage caused by use of a non-Printek power
supply will not be covered by the printer’s warranty.

When the power supply is connected, the printer’s charging circuitry will determine if the battery currently
requires charging and if so, will turn on the Battery Indicator until the battery has reached sufficient charge.
Depending on the condition of the battery, charging may take up to 2½ hours to complete.
Leaving the power supply connected to the printer will cause the printer to continuously monitor the condition
of the battery and keep the battery charged.
