the following operations are possible depending on the MFP’s status:

system (UPS) or inverter is used.

Backing Up Data in Memory
Even if the power goes out or you turn off the MFP, the data for fax 
transmissions and received faxes is retained for 72 hours as long as 
it is stored in the MFP memory.

When the electricity supply is restored,
