Class 347
INCREMENTAL PRINTING OF SYMBOLIC INFORMATION
Class Definition:
This class provides for processes and apparatus for conveying
information by selectively creating on a medium a visibly
distinguishable symbol* or mark* composed of a plurality of
portions*. The symbol* or mark* is created portion* by
portion* as, for example, by pixels or dots. The symbol* or
mark* may be an alphanumeric character or an image.
SCOPE OF THIS CLASS (347)
(1) Note. The symbol* or mark* is created portion* by
portion*. A symbol* or mark* which is not created portion* by
portion* is found elsewhere. For example, printing type,
typewriters, stencils, and hand stamps create a whole mark*
rather than a mark* portion* by portion*. (see References to
Other Classes, below, for these latter classes)
(2) Note. The symbol or mark which is created using a
character supporting electrode stylus by which an
electrostatic charge is deposited onto or discharged from a
medium is, however, classified in this class (347).
(3) Note. The symbol* or mark* conveys information.
Information is the communication of knowledge or
intelligence. For example, an alphanumeric character and an
image are marks* which convey information. A code (e.g., a
bar code) is a mark* which conveys information.
(4) Note. A visibly distinguishable mark* created portion*
by portion* for a purpose other than conveying information is
found elsewhere. For an example of a coating formed in this
manner, see References to Other Classes below.
(5) Note. Some portion* by portion* marks* in a specific
situation are found elsewhere. For a portion* by portion*
mark in the production of a printing plate see References to
Other Classes, below.
(6) Note. The marking* can be combined* for a special
purpose. Special purpose devices are found elsewhere; e.g.,
facsimile devices, electrophotos:graphic copiers, labelers,
and recorders. (see References to Other Classes, below.)
(7) Note. The marking* device is made up of several
portions*: a combined* portion, a controller portion, a head*
portion, a marking* portion, a medium portion, and a housing
portion. The combined* portion is the combination of a
marking* device and an external means which functions as a
special information marking* system. The controller portion
contains the means to direct the operation of the marking*
device or any of its component parts. The head* portion
contains the means which provides the marking*. The marking*
portion contains the specifics of the marking* (e.g., the
fluid, the impact, the heat, the electricity, and the
radiation). The mechanism portion contains the medium, its
handling, and its processing. The housing portion* contains
an outer enclosure for the marking* device.
LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
This class (347) provides for "stand-alone" incremental
printers such as ink jet, laser, thermal, dot-matrix, or
electrostatic printers. These devices, for the most part, are
now classified in Class 346, Recorders, and Class 400,
Typewriting Machines.
Other types of informational marking* are found elsewhere.
See References to Other Classes, below.
Subcombinations of this subject matter can be found in
various areas. For example, media and media handling means
are found elsewhere (see References to Other Classes, below)
As these arts are reclassified, appropriate subject matter
will be transferred to this class (347). See Other
Classification Systems, below, for the appropriate IPC
subclass for the art of this class (347).

GLOSSARY:
The following terms have been defined for purposes of
classification in this class. In the class and subclass
definition of this class, terms used in a sense defined below
are indicated by an asterisk(*).
COMBINED
Means connected with the marking* device for adapting the
device to a particular marking* purpose.
CONTROL
Means to regulate the operation of the head*, the medium, and
the other parts of the marking* device so that the device
will operate in the intended manner.
EJECTOR
The mechanism which projects the fluid* onto the medium*.
FLUID
The flowable substance which is projected from the ejector*
mechanism or which is used to enhance the transport or
generation of charged particles.
HEAD (Marker)
The section of the marking device which produces the visibly
distinguishable or latent symbol or mark on the medium in
accordance with an information signal.
MARK
A discrete area on the medium which contains the plurality of
portions*. Unless otherwise indicated, "mark" and "symbol"
are used synonymously in the subclass definitions of this
class.
MARKING
The specific manner by which the mark* is formed; e.g., ink
jet, impact, thermal, electric (e.g., toner applied to a
latent image), or radiation.
MEDIUM
A substrate on which the visibly distinguishable or latent
symbol or mark is formed.

Elemental sections of a symbol* or mark*. An elemental
section is not, itself, a symbol* or mark* as, for example,
is an alphanumeric typeface used to create a picture or an
image.
SYMBOL

otherwise indicated, "mark" and "symbol" are used
synonymously in the subclass definitions of this class.

force for producing the mark*.
SUBCLASSES
Subclass:
1
INK JET:
This subclass is indented under the class definition.
Subject matter wherein the symbol* or mark* is created by a
projection of fluid onto a medium in a controlled manner. The
fluid is projected by an ejector which does not contact the
medium.
(1) Note. An ink jet generally includes a fluid*, an
ejector*, a medium* for receiving the projected fluid*, and a
controller. The projected fluid* on the medium* forms the
marking* which represents a visualization of the
information.
(2) Note. The fluid* can be any substance that flows.
Generally, it is an ink, but it can be other substances such
as powder, gas, etc., or a combination of these substances.
Generally, the fluid*, per se, is classified with the fluid*
except where a specific interconnection with the ink jet is
claimed. For example, an ink for use in an ink jet would
still be classified in Class 106. When other factors such as
printing density or droplet volume are recited,
classification in subclasses 84+ of this class (347) could be
appropriate. Ink jet fluids* are classified in this class
(347). Ink with a nominal recitation of ink jet is
classified in Class 106, especially with ink jet composition
or process. Also, ink compositions containing synthetic
resins are classified elsewhere. Fluid* handling is
classified in this class (347). Fluid* handling details such
as pumps, valves, and filters with a nominal recitation of
ink jet are classified in the classes appropriate to the
details.
(3) Note. The medium* can be any substrate which accepts
fluids*. Mediums are a stock material which is classified in
Class 428. When specifics such as ink compositions and
medium handling are recited especially adapting the medium to
the ink jet, classification could be appropriate in this
class (347). A distinction within this class (Class 347) is
made between an object and a medium. An object is a
specialized medium. For example, wire, containers, envelopes,
and checks are considered objects. The ink jet informational
marking* of objects is classified in this class (347). Means
especially adapted to handle and/or process ink jet mediums
can be found in this class (347). Medium handling means, in
general, are classified elsewhere. See the search notes
below.
(4) Note. Ink jet marking* is considered to be the
visualization of information. Other terms such as printing,
recording, and imaging can also be used to describe this
marking*. The use of ink jet techniques for other purposes,
such as particle sorting, is not considered marking* and
therefor not appropriately classified in this class. The
projection of fluid* which is not ink jet is provided in
other classes. The contact projection of fluid* onto a
medium* for informational marking* is classified elsewhere.
See the Se
(5) Note. Ink jet combined* with a nominal recitation of
some other apparatus is classified in this class (347).
Nominal ink jet combined* with a significant apparatus is
classified with that apparatus and cross-referenced into this
class (347). See the Search This Class, Subclass notes
below.
(6) Note. The control* is an element which regulates all or
some part of the ink jet. For example, a central processing
unit (CPU) in the ink jet would be a control*, not a
combined*.
(7) Note. A computer which regulates all or some part of
the ink jet would be classified in this class (347). A
computer, per se, would be appropriately classified
elsewhere. An interface unit for an ink jet would be
appropriate elsewhere.

other apparatus, including ink jet informational marking* of
