Ricoh 170 / 180 - Manual (Page 123)

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 (a 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 ITU-T). 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 Codes:
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 memory together with instructions (destinations,
time of transmission) for sending that document.
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 Transmission and if you are not using ECM (ECM is a
more effective data retransmission method).
