needs to place the character patterns on a page.
Coded fonts are typically used where typographic
quality is required.
code point. An element of a code page or a site in a
code table to which a character can be assigned.
configuration. (1) The arrangement of a computer
system or network as defined by the nature, the
number, and the chief characteristics of its functional
units. More specifically, the term configuration may
refer to a hardware configuration or a software
configuration. (2) The devices and programs that make
up a system, subsystem, or network.
configure. The procedure used to customize the
printer to a specific operating and communication
environment.
constant data. Data that does not change; for
example, the company letterhead and standard text in
form letters, or the headings and boxes on a preprinted
form. Contrast with
variable data.
constant spaced font. A font in which the graphic
characters are contained in character cells of uniform
size. The distance between reference points of
adjacent graphic characters is constant in the inline
progression. The white spaces between graphic
characters may vary. Synonymous with
fixed space
font. Contrast with proportionally spaced font.
control storage. In the InfoPrint 60 and 3160, a
portion of storage that contains microcode and other
data.
control unit (CU). (1) A device that controls input and
output operations at one or more devices. (2) In the
InfoPrint 60 and 3160, the electronics and code that
control the printhead and the attachment to the host
processor.
controlling computer. The processing unit to which
the printer is connected through a communication
attachment.
controlling computer system. The data-processing
system to which a network is connected and with which
the system can communicate.
corner cut. On a page, a cut or opening of any size
containing one or more right angles.
corona. A small diameter wire (or wires, depending on
the function) to which a high voltage is applied, causing
ionization of the air. The ionization creates an electrical
charge to perform various functions during the printing
process.
copy group. One or more copies of a sheet of paper.
Each may have modifications applied; for example,
overlays and text suppression.
copy modification. The process of adding, deleting,
or replacing data on selected copies of certain sheets of
paper.
copy separation. The mechanism for distinguishing
consecutive copies of a single data set. In the stacker,
it consists of offset stacking.
cure. The process of drying ink sufficiently for
minimum transfer of the ink to any parts of the printer it
contacts.
customer engineer. See service representative
cut. The severed part of a perforation. Cuts are
separated by ties. See also
perforation.
cutout. A part of a page that has been eliminated or
perforated for subsequent removal; for example, corner
cuts and binder holes.
D
developed image. The image that has been exposed
onto the photoconductor and covered with toner by the
developer.
developer. The unit in the process assembly that
supplies a flow of developer mix (toner) over the
photoconductor to develop the electrostatic image.
diagnostic. Pertaining to the detection and isolation of
errors in programs and faults in equipment.
diagnostic mode. The operational mode in which the
printer can check itself in case of a malfunction. When
the printer is in diagnostic mode, it is not accepting
information from the attached controlling computer
system. In the InfoPrint 60 and 3160, only service
representatives can use diagnostic mode. Contrast with
print mode and test mode.
direct attach. The environment in which an application
program directly allocates the printer.
disabled mechanism. If necessary, the operator can
disable some printer functions to continue operation
until a problem can be corrected. In the InfoPrint 60
and 3160, the mechanisms that can be disabled are the
top paper supply, the bottom paper supply, the duplex
mechanism, and the offset-stacker mechanism.
diskette. A flexible, magnetic disk enclosed in a
protective container.
