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.
For more information regarding battery charging, battery life and battery disposal, refer to “Battery Care” on page 40.
Using the Magnetic Card Reader
The optional Magnetic Card Reader (MCR) is used by some applications to read information from credit cards, drivers licenses, etc.
When the host system sends a request to the MLP 3040 to enable the Magnetic Card Reader, “Swipe Card Now” will be displayed and the 
MCR Indicator will flash to indicate that the card may now be passed through the MCR slot, or “swiped”. Refer to Figure 9 for the card orientation and note the position of the magnetic strip.
