What Happens to the Memory After a Power
Failure?
If power to the machine is lost due to a power failure, or if the machine is
accidentally disconnected, a built-in battery keeps a trickle of current supplied to
the memory so all of the documents currently stored in memory can be saved for up
to 12 hours.
How Your Registered Data Is Protected
This is what happens when the machine is disconnected:
• The backup battery takes over and keeps a trickle of current flowing to the memory in
order to preserve all of the documents that are waiting to be sent or printed.
• However, if the machine is turned OFF for longer than 12 hours, all of the
documents in the machine’s memory are lost after the battery power runs down.
As soon as power is restored to the machine a Memory Clear Report is printed
which shows you the documents that were erased. (See “Memory Clear Report,”
on p. 12-17.)
• Your user data and speed dialing settings are constantly refreshed by a lithium
battery, and they are not lost as a result of a power failure. This is true even if
power to the machine is cut OFF for longer than 12 hours.
• If many documents are stored in the machine’s memory, the machine may need
about two minutes to recover after power is restored to the machine.
About the Backup Battery
Here is a list of things to keep in mind about the backup battery.
• The backup battery is a rechargeable battery, which preserves document data in
the memory for up to 12 hours. The battery requires about one day to reach a full
charge after power to the machine is restored.
• Frequently disconnecting the machine from the power source shortens the service
life of the battery.
• To avoid shortening the backup battery’s service life, use the machine within a
temperature range between 50°F to 90.5°F (10°C to 32.5°C). If the machine is
used in an environment that is too hot or too cold, the service life of the backup
battery may be shortened.
