Set the fax speed You can set the fax speed used to communicate between your printer and other fax machines when sending and receiving faxes. 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 • Fax over Internet Protocol (FoIP) • An integrated services digital network (ISDN) service If you experience problems sending and receiving faxes, try using a lower fax speed. The following table provides the available fax speed settings. Fax speed setting Fast Medium Slow Fax speed v.34 (33600 baud) v.17 (14400 baud) v.29 (9600 baud) To set the fax speed 1.

Set the Error Correction Mode Error Correction Mode (ECM) prevents loss of data 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 if you can accept poorer quality in exchange for reduced charges. Change fax settings 63
