Replacing the Backup Battery

When the backup battery is at its end of life, the printer's date and time cannot be retained. Follow the

procedure described below to replace the backup battery.

Note:

Only use the coin-shaped 3V lithium battery CR2032. It's very important to protect the printer controller

board and any associated circuit boards from electrostatic damage. In addition, always handle circuit

boards by the edges only.

1. Turn off the printer and disconnect the power cord and interface cables.

2. Using a screwdriver, remove two screws.

3. Slide the panel slightly to the down and lift it off the printer.
