Error Correction (ECM)
You can select this option to reduce system and line errors when
sending a fax. With this option selected, the system checks each
outgoing fax for lost data. If data has been lost from a portion of a
page, the system transmits that portion again after confirming that all
data within that portion can be transmitted successfully.
Auto Start Send
When you select this option, the unit starts scanning automatically if
a speed dial number is pressed, or when a destination is entered and
the START/COPY button pressed. When you don't select this option,
you must press START/COPY twice to scan the document.
Off Hook Alarm
You can select this option to turn on the alarm after the MultiPASS
printer has received or sent a fax if the telephone handset is off-hook.
Image Contrast
You can 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 can 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 can select this option if you want the MultiPASS printer 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.
