Troubleshooting
If a Power Failure Occurs (MF4380dn/MF4370dn/MF4350d/MF4340d Only)
If a Power Failure Occurs (MF4380dn/
MF4370dn/MF4350d/MF4340d Only)
If a power failure occurs, machine functions will be limited as follows:
Depending on your telephone, you may not be able to make telephone calls.
You can receive telephone calls from the optional handset or the telephone connected to
the machine.
You cannot send, receive, or copy documents.
Even if power is suddenly lost due to a power failure or accidental unplugging, any sent or
received documents stored in memory are backed up for about 5 minutes. However, after
this period of time, the machine may lose any data stored in the memory. If this happens,
the display shows <LOST IMAGE> when power is restored and automatically prints a Lost
Report (unless the cartridge is empty or there is no paper in the machine) that lists the
documents (received in the last 60 transactions) that were lost from memory as a result of
the power cut.
