Default
The setting your machine will always refer to if no other action has been programmed.
For example, you can set the default for this machine to send a fax by using its memory. I f y o u s e t
this action as the default, that s how your machine will always send a fax, until you tell it to do dif-
ferently.
Delayed command
Transmission or polling operation set by the user to occur later, automati-
c a l l y, at a predetermined time. Great for reducing costs by making fax calls during times when
telephone costs are lowest, such as late at night or on weekends.
Digita l Using the binary system (which uses a combination of 0s o r 1s) to describe everything,
so that 0 means o f f and 1 means on; d i g i tal fax machines convert the graphic image of your docu-
ment into a series of zeros and ones by using the binary system of transmission to encode black
and white occurrences. This increases transmission speed by passing over white spaces. See
also White-line skip.
Digital fax Unlike analog systems that scan every portion of a document, digital fax machines
survey a document s overall picture content. Digital fax machines scan a line and convert the
information into a binary code of zeros and ones. The fax machine takes this information and
compresses it, providing high transmission speeds. Many Muratec units o ffer proprietary methods
for faster transmissions between Muratec-manufactured units (see also

Document feeder
The adjustable slot into which users place documents for faxing or copying.
Effective printing widt h
The widest image that can be printed on a fax.
Effective scan widt h
The maximum width the scanner in a fax can scan during transmission.
F-Code
A fax-industry standard created by the
munications. Because F-Code is an industry standard, Muratec fax machines as well as all
equipped fax machines from other manufacturers can communicate with each other using sub-
addressing.
Facsimile ( o r fax) A form of communication involving the scanning and decoding of a document
into electrical signals and transmitting of the document, over telephone lines to another device.
This device then reconstructs the signals to produce an exact duplicate of the document. Also, a
machine that performs such communication.
Fallback Group 3 fax machines operate at the highest transmission speed possible on a given
telephone line. Muratec systems offer automatic fallback; if line quality drops during transmission,
the fax machine will reduce speed to the fastest possible level.
File number
A number the machine gives to each document it stores for a batch, F-Code or
polling operation.

Grayscale Not a level of resolution, but a method of scanning and transmitting halftone
images. Fax machines with grayscale abilities interpret photographs in
levels of gray between white and black. The transmitting fax machine must have grayscale ability
to send a photographic image accurately, but the receiving machine does not need it to print the
image.
