5 Back-Up Battery
5.1 Back-Up Mechanism
5.1.1 Outline
The machine’s image processor is equipped with a lithium battery (BAT1) and a vana-
dium lithium secondary battery (BAT2) for data back-up, needed in the event of a power
shortage or when the power switch is tuned off.
A : BAT2, however, is used to back up image data related to fax functions, and is used
only in the fax model.
Do not throw the lithium battery and vanadium lithium secondary battery
into fire. It contains lithium and organic solvent (highly combustible), and it
can explode or burn with strong intensity in fire.
Also, do not disassemble it, as its organic solvent can harm your skin upon
contact.
Take full care when handling the battery, and be sure to dispose of it ac-
cording to appropriate regulations.
5.1.2 Vanadium Lithium Secondary Battery (BAT2)
The fax model is equipped with a vanadium lithium secondary battery (BAT2), mainly
used to back up image data. The period of backing up data and the life of the battery are as
follows:
Backup period : about 1 hr (machine's power switch kept ON for a day or longer under
normal temperature and atmospheric pressure)
Life of battery : about 5 yr or charging/discharging 20 times (w/ 64MB expansion
memory) to 50 times (w/ standard memory)
When the vanadium lithium battery (BAT2) reaches the end of its life, the display will in-
dicate 'DATA ERROR' when the machine is turned on.
The machine does not allow replacement of BAT2 on its own. When it has become ex-
hausted, be sure to replace the image processor PCB as a whole.
The data retained by the battery is image data resulting from fax transmission/reception,
and the image data occurring in memory copying will not be retained.
The data retained in image memory will be lost when the aforementioned
backup period passes. The image data will also be lost if the switch (JP2)
on the image processor PCB is set to OFF. To prevent the loss of data dur-
ing service work, be sure to print out the contents of the memory before
starting the work.
