The Battery is located on the Main Logic Board of the Printer. It is
recommended that a qualified service technician replace this Battery since

discarding used batteries, do not incinerate.
CAUTION: Turn the printer’s AC Power Switch OFF and disconnect the

electrostatic and electrical safety precautions.
To remove the old Battery, gently raise the left edge and slide the Battery to the
left and out of the Battery Holder.
