Will I lose faxes if the product is turned off?

No, you can set up your product to store faxes when it is turned off.

To enable this feature, press the home button, if necessary. Select Settings > General Settings > Fax Settings > Receive Settings > Save/Forward Settings > Unconditional Save/Forward, and set Save to Inbox to On.

Note: Delete faxes after you print or view them to prevent the product's memory from filling up. When the memory is full, you can only forward or print incoming faxes.
