CHAPTER 4 OPERATION
8.2 Back-Up Batteries
8.2.1 Back-Up Function
8.2.1.1 Outline
The machine’s image processor PCB is equipped with a lithium battery (BAT1) and a va-
nadium lithium secondary battery (BAT2) for back-up of the data in the SRAM and the
SDARM in consideration of a power outage or when the power is turned off.
The lithium battery (BAT1) and the vanadium lithium secondary battery
(BAT2) contain combustible material (lithium, organic solvent), and can
burst or burn in flames if thrown into fire.
Take full care in handling the batteries, as taking them apart can cause the
organic solvent to leak to damage the skin. To dispose, be sure to separate
them from other items and observe appropriate rules.
8.2.1.2 Lithium Battery (BAT1)
The data backed up in the SRAM by the lithium battery (BAT1) contains user data for fax
functions, communications control data, and service mode settings.
Battery life:
about 5 yr
The LCD will indicate ‘DATA ERROR’ when the power is tuned on after the lithium bat-
tery (BAT1) has reached the end of its life. If such a condition has occurred, be sure to re-
place the image processor PCB according to the instructions given in 1.4.1 of Chapter 7.
If you disconnect the jumper plug (JP1) of the image processor PCB and
turn off the power, all control data will be reset to default settings. Do not
disconnect the jumper plug (JP1) to prevent the loss of data.
Memo
The pin of the jumper plug (JP1) is displaced on the image processor PCB
available as a service part so as to prevent exhaustion of the lithium battery
(BAT1).
