User manual
Default — The setting your machine will always refer to if no other action has been pro-
grammed. For example, you can set the default for this machine to send a fax by using its
memory. If you set this action as the default, that’s how your machine will always send a fax,
until you tell it differently.
Delayed command — Transmission or polling operation set by the user to occur later, auto-
matically, 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.
Digital — Using the binary system (which uses a combination of 0s or 1s) to describe every-
thing,so that 0 means off and 1 means on; digital fax machines convert the graphic image of
your document 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
offer proprietary methods for faster transmissions between Muratec-manufactured units (see
also
MSE
,
SMSE
).
DIP
switches — Dual in-line package switch; a two-position on/off switch. Many Muratec fax
machines include
DIP
switches to control optional settings or features.
Document feeder — The adjustable slot into which users place documents for faxing or
copying.
Effective printing width — The widest image that can be printed on a fax.
Effective scan width — The maximum width the scanner in a fax can scan during trans-
mission.
F-Code — A fax-industry standard created by the
ITU
-
T
for sub-addressing/password-based
communications.Because F-Code is an industry standard, Muratec fax machines as well as
all
ITU
-
T
equipped fax machines from other manufacturers can communicate with each other
using sub-addressing.
Facsimile (or fax) — A form of communication involving the scanning and decoding of a docu-
ment 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.

(“Group 3 fine”) on some fax units.
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 photo-
graphic image accurately, but the receiving machine does not need it to print the image.
Group 3 — Refers to fax machines that use digital encoding. These units transmit one page
in less than one minute and produce resolution of 203 × 98, 203 × 196, or 406 × 392 lpi.
Halftone — See Grayscale.
Handshaking — An exchange of data between telecommunications and/or
computer equipment that “introduces” two systems to each other. For example, faxes use a
handshaking protocol to identify the
ITU
-
T
group of each unit and to begin fax communication.
Hub — See Relay broadcasting.
Hz (or Hertz) — A measure of frequency equal to one cycle per second. Used in the specifica-
tions for a fax machine,it identifies the
AC
power the unit requires.

transmission. Muratec Group 3 fax machines offer the fastest transmissions allowed by the

Laser printing — A plain-paper printing system.Toner is attached to a charged drum and
an image is transferred onto plain paper through electrical currents,then fused with heat
and pressure to produce a dry, permanent printout.
