Ricoh 170 / 180 DPI Dots Per Inch, or L/mm Lines Per Millimeter, ECM a Error Correction Mode

GLOSSARY

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).
