sending or receiving from another fax machine with ECM capability. ECM is most
effective in areas where the telephone lines are in poor condition or there is frequent
interference on the line.

known as factory default settings. You can customize your unit by changing the factory
default settings.

telephone. With this feature, one telephone line can be shared by both the telephone

FINE
The resolution setting for documents with very small characters and lines.
■ G
G3, Group 3 fax machine
Defined by ITU-T. Uses encoding schemes to transmit image data while reducing the
amount of data that needs to be transmitted, thus reducing transmission time. G3 fax
machines can transmit one page in less than one minute. Encoding schemes for G3
fax machines are Modified Huffman (MH), Modified READ (MR), and Modified Modified
READ (MMR).
Grayscale

colors and intensities of colors appear as different shades of gray.
Group dialing
A dialing method that enables you to dial up to 123 registered one-touch speed dialing
or coded speed dialing numbers together as a group. This means that you can press
just one or three buttons to enter numbers when sending the same document to many
destinations.
■ H
