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. Before performing this procedure,
review the antistatic caution on“Antistatic Protection” on page 146. 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.
