24-hour format Also called milit ary format. A format for keeping time that does not use a.m. or
p.m. to distinguish between morning and afternoon. In the 24-hour format, one o clock in the
morning marks 1:00, noon marks 12:00 and midnight marks 24:00. To calculate the 24-hour for -
mat, add 12 hours to all times after noon.
For example, 1:30 p.m. would be 13:30 in the 24-hour format; 10:45 p.m. would be 22:45 in the
24-hour format. And 11:15 a.m. would be 11:15 in the 24-hour format.
A3, A4, B4 Standard st ationery sizes defined by the International Standards Organization, an
agency of the United Nations. See also Paper sizes.
ADF Automatic document feeder. See document feeder.
Alternate number The number your machine dials after all attempt s to the regular number fail.
The user programs this alternate number, if so desired.
Answering machine See
TA D
.
Autodialing Enables user to store preprogrammed telephone numbers in the unit s memory.
S torage cap ability varies from unit to unit.
Automatic fallback The ability of a fax machine to slow down ( fall back ), when communicat-
ing with another fax which is communicating at a slower rate.
Automatic reduction Many Muratec fax machines will automatically reduce the size of docu-
ments being transmitted to accommodate the effective printing wid th of the receiving unit. For
example, this allows a fax machine with a 10″ (256 mm) scanning width to send an image 10 ″
(256 mm) wide to a unit with an 8.3 ″ (210 mm) print width. The receiving fax machine will receive
a reduced-size printout of the complete image.
Bit The smallest unit of information in a computer. Some Muratec fax machines, which are
actually computers dedicated to telecommunications, allow users to change bits of information
to provide or cancel features through software settings.
Bits per second See bps.
Black density Also called black coverage. The amount of non-white area on a page. For
example, most regular office correspondence has a black density well under 10%, due to the
presence of margins, spaces between words, spaces between lines and paragraphs and even
spaces within letters .However, drawings and photographs have a much higher black density,
sometimes approaching 100%. The higher a page s black density, the more slowly a fax machine
sends it.
Broadcast A fax transmission in which a single document is sent to more than one location.
b ps Bits per second. Used to express the speed of transmission of data. Because fax trans-
mission treat s a document as a graphic image rather than as a series of alphabetic and numeric
characters, bps does not correspond to the number of characters transmitted per second.
Byte A group of digit al elements, usually sent as eight bit s to the byte.
Call reserve Also called call request. An

T
standard fax feature which allows a user to
request voice communication prior to, during or after transmission.
Call-waiting service An optional telephone company service that alert s you to another incom-
ing call when the phone is already in use. Call-waiting signals of ten cause interruption of fax
transmission or reception.
Caller
ID

display of the number (phone or fax) that is calling.

used in some Muratec fax machines. The

Command queue The list your machine keeps of all its pending commands.
Command number The number your machine gives to each job it is programmed to com-
plete. You must know the command number in order to cancel or change any of the machine s
jobs that it stores.
Compatibility The term compatible describes the ability of sep arate things to function
together. Your Muratec fax machine features
