Note If Backup Fax Reception is On and there is an error condition, the HP all-in-one
stores the faxes it receives in memory as "unprinted." All unprinted faxes remain
in memory until they are printed or deleted. When the memory becomes full of
unprinted faxes, the HP all-in-one will not receive any more fax calls until the
unprinted faxes are printed or deleted from memory. For information on printing
or deleting faxes from memory, see Reprint or delete the faxes in memory.
The default Backup Fax Reception setting is On.
To set backup fax reception from the control panel
1 Press Setup.
2 Press 5, and then press 5 again.
This displays the Advanced Fax Setup menu and then selects Backup Fax
Reception.
3 Press
to select On or Off.
4 Press OK.
Use error correction mode
Error Correction Mode (ECM) eliminates data that is lost due to poor phone lines by
detecting errors that occur during transmission and automatically requesting
retransmission of the erroneous portion. Phone charges are unaffected, or might even
be reduced, on good phone lines. On poor phone lines, ECM increases sending time
and phone charges, but sends the data much more reliably. The default setting is on.
Turn ECM off only if it increases phone charges substantially, and you can accept
poorer quality in exchange for reduced charges.
The following rules apply to ECM:
● If you turn ECM off, this applies only to faxes that you send. This does not apply to
faxes that you receive.
● If you turn ECM off, set the Fax Speed to Medium. If the Fax Speed is set to Fast,
the fax will automatically be sent with ECM on. For information on changing the Fax
Speed, see Set the fax speed.
● If you send a fax in color, the fax will be sent with ECM on, regardless of the option
currently set.
To change the ECM setting from the control panel
1 Press Setup.
2 Press 5, and then press 6.
This displays the Advanced Fax Setup menu and then selects Error Correction
Mode.
3 Press
to select Off or On.
4 Press OK.
Set the fax speed
You can set the fax speed used to communicate between your HP all-in-one and other

required:
● An Internet phone service
