You should have received a printer with a coin cell
battery already installed in the printer.
The backup battery is a 3-volt lithium coin cell.
You can buy additional backup batteries at most
stores, part # CR2032.
NOTE: You must use a fully charged main battery when replacing the
coin cell.
You must turn the printer on, wait until the printer fully
initializes, then turn the printer off again. This will help to further
reduce the coin cell life.
Switch backup batteries when you receive a CMOS error.
