DPI (Dots Per Inch), or l/mm (Lines Per Millimeter):
This is the unit of resolution. The scanner scans your document according to the
selected resolution. An 8-1/2" x 11" page is broken down into about 1,728,000
dots if standard resolution is used. (Digital compression techniques for G3 convert
these into about 200,000 bits.)
ECM (Error Correction Mode): This is signaling method that is designed to
eliminate transmission errors on even the noisiest of telephone lines. See page .
EFC:
This is a proprietary digital data compression technique. It shortens the time for
sending a page.
Factory Setting:
The factory setting of a function is the state into which it was programmed at the
factory; this will also be the state of that function in a new machine. It can also
referred to as "Default Setting".
File:
☞ Memory File, Polling File.
Group 3:
This is an internationally-agreed signaling and data transfer method used for
facsimile communication (approved by CCITT). It is also known as G3.
Handset:
This is the telephone that is connected to the jack marked "TEL".
Home Position:
Some of your machine’s features can be adjusted. The home position is the
setting to which the machine always returns at the end of an operation.
International Dialing Code:
This is the code that must be dialed at the beginning of the number if the
destination is outside your country.
Memory File:
This is a document stored in the SAF memory (see the next page) and the
instructions (destinations, time of transmission) for sending that document.
Modem:
Acronym for modulator/demodulator. A device that transforms a digital signal into
a form suitable for transmission over the telephone network.
Original:
Same as "Document".
Page Retransmission:
If the terminal you are sending to indicates that it did not properly receive the
page you just sent, your terminal will resend that page from memory. This only
works if you used Memory Mode and if you are not using ECM. (ECM is a more
effective data retransmission method.)
