User's Manual

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 selects Advanced Fax Setup 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 selects Advanced Fax Setup 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 fax machines when sending and receiving faxes. The default fax speed is Fast.
If you use one of the following, setting the fax speed to a slower speed might be
required:
● An Internet phone service
● A PBX system
