Replacing the Lithium Battery in the Fax Cartridge The fax cartridge contains a small battery that controls the time and date clock. This battery will should be changed every two to three years. To replace the battery, turn off the power to the printer. Disconnect the phone cables from the jacks and remove the fax cartridge. CAUTION: Be sure the printer's power is turned off before the fax cartridge is installed.

Remove two screws from the fax cartridge case. Gently pry the case apart to expose the circuit board. Remove the old battery. Replace the old battery with a new 2032 lithium coin cell battery.
The battery will be marked with a plus sign (+) on one side and a minus sign (-) on the other side. Make sure that the plus (+) side is facing up when the new battery is installed. 5. 6. Put the cartridge case back together and replace the screws. Place the cartridge back in the printer and replace the phone cables.
Once the power is turned back on to the printer, the time and the date must be reset. (See "Clock Setup" in the Fax User's Manual.)
