Menu item Description
Redial On No Answer The Redial On No Answer setting selects the number of times the fax accessory redials if
the number dialed does not answer. The number of retries is either 0 to 1 (used in the
U.S.) or 0 to 2, depending on the country/region setting. The interval between retries is
set by the redial interval setting.
Detect Dial Tone The Detect Dial Tone setting determines whether the fax checks for a dial tone before
sending a fax.
Dialing Prefix The Dialing Prefix setting allows you to enter a prefix number (such as a "9" to access an
outside line) when dialing. This prefix number is automatically added to all phone
numbers when dialed.

Menu item Description
Fax Number Confirmation When the Fax Number Confirmation feature is enabled, the fax number must be entered
twice to ensure that it was entered correctly. The feature is disabled by default.
PC Fax Send Use the PC Fax Send feature to send faxes from a PC. This feature is enabled by default.
Fax Header Use the Fax Header feature to control whether the header is appended to the top, and
content is shifted down, or if the header is overlayed on top of the previous header.
JBIG Compression Enabling the JBIG Compression feature can reduce phone-call charges by reducing fax
transmission time and might be the preferred setting. However, using the JBIG
Compression feature might cause compatibility problems when communicating with
some older fax machines, in which case you might need to disable it.
NOTE: The JBIG Compression feature works only when both the sending and receiving
machines have this capability.
