HP 7200 manual Use error correction mode, Set the fax speed

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.
