GLOSSARY
Dial Pulses:
These are dialing signals that your terminal sends out if it uses pulse dialling.
Document:
This is the original page or set of pages that you wish to send.
DPI (Dots Per Inch), or I/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.
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 be referred to as "Default Setting".
File:
A memory File or a 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 1" or "TEL2".
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.
