Auto Start Send
When you select this option, the unit starts scanning automatically
five or ten seconds after destinations are entered. When you do not
select this option, you must press START/COPY to scan the
document, or the unit returns to standby mode after 60 seconds.
Off Hook Alarm
You select this option to turn on the alarm if the telephone handset is
off-hook.
Image Contrast
You select a setting that determines the level of contrast in the faxes
you send. The Standard setting is usually appropriate for most
documents. However, based on the lightness or darkness of your
original fax document, you may prefer to lighten or darken the
contrast for the fax transmission.
Fax Heading Position
You select where you want the sent fax heading information (your fax
number, your name, and date and time) to print on the faxes you send.
This information is known as the Transmit Terminal Identification
(TTI).
On Error Resend
You select this option if you want the C50 to automatically redial if an
error occurs while sending a fax. If this option is selected, you also
select which pages should be resent: only the page on which the error
occurred, the page on which the error occurred and the first page of
the fax, or all pages.
R-Key
The R-Key options enable you to define the R-Key settings for your
C50. The options determine whether or not you are connecting your
C50 to a PBX (Private Branch Exchange) line to send PC faxes. If you
are connecting to a PBX, you also select the type of PBX line.
If you are connecting to a PBX line, you select PBX. Otherwise, you
select PSTN.
