The following Backup Fax Reception modes are available: On, On Error Only, and Off.
●On is the default setting. When Backup Fax Reception is On, the HP All-in-One stores all faxes it receives in memory. This enables you to reprint up to eight of the most recently printed faxes if they are still saved in memory. For more information, see Reprint received faxes from memory.
Note After the memory becomes full, the HP All-in-One overwrites the oldest, printed faxes as it receives new faxes. If the memory becomes full of unprinted faxes, the HP All-in-One will stop answering incoming fax calls.
●On Error Only causes the HP All-in-One to store faxes in memory only if there is an error condition that prevents the HP All-in-One from printing the faxes (for example, if the HP All-in-One runs out of paper). The HP All-in-One will continue to store incoming faxes as long as there is memory available. (If the memory becomes full, the HP All-in-One will stop answering incoming fax calls.) When the error condition is resolved, the faxes stored in memory print automatically and are then deleted from memory.
●Off means that faxes are never stored in memory. (You might want to turn off Backup Fax Reception for security purposes, for example.) If an error condition occurs that prevents the HP All-in-One from printing (for example, the HP All-in- One runs out of paper), the HP All-in-One will stop answering incoming fax calls.
Note If Backup Fax Reception is enabled and you turn off the HP All-in- One, all faxes stored in memory are deleted, including any unprinted faxes that you might have received while the HP All-in-One was in an error condition. You will need to contact the senders to ask them to resend any unprinted faxes. (For a list of the faxes you have received, print the fax log. The fax log, containing a list of the numbers from which you have received faxes, is not deleted when the HP All-in-One is turned off. For more information on the fax log, see the onscreen HP Image Zone Help.)

Reprint received faxes from memory
If you set the Backup Fax Reception mode to On, the HP All-in-One stores faxes it receives in memory, whether the device has an error condition or not. For more information, see Set up backup fax reception.
Note The HP All-in-One deletes all the faxes stored in its memory when you turn off the HP All-in-One. You can also delete the faxes from memory by clearing the fax log from the Setup Menu, or changing the Backup Fax Reception mode to Off. For more information, see the onscreen HP Image Zone Help.
