A method and apparatus are provided to control the atmosphere inside of a xerographic control module of an image forming device so that a dew point condition is not reached. The parameters of the atmosphere within the xerographic chamber which are controlled include pressure, temperature and humidity.

Method and apparatus for controlling humidity in a copying device

An exterior or interior structural member in the form of a panel for an image forming or similar device is disclosed which has an integral plenum passage for fluid/air. The panel may be thermoformed and/or have mechanically connected parts, and may include other elements, such as toner bottle covers.

Integral plenum panel

A method and apparatus for maintaining the air pressure within a xerographic module/chamber of an image forming device above ambient pressure outside of the xerographic module/chamber which uses a pressure sensor, e.g., an altimeter to monitor ambient atmospheric pressure, and a microprocessor to control and maintain air pressure to a determined set point.

Ambient atmospheric pressure compensation controller for pressurized copying device

An apparatus for maintaining an ambient condition about a marking module. The apparatus includes a substantially air impervious enclosure defining a chamber having the marking module disposed therein. An air flow source supplies air to the chamber, and sensors respond to the amount of air flow to control the air flowing from the air source.

Apparatus for controlling air flow in a printing machine

An apparatus for maintaining a uniform temperature along its axis by increasing the heat transfer efficiency. The apparatus uses a sealed chamber containing a substantially pure working fluid in a two phase (liquid and vapor) condition. The vaporization and condensation of the fluid increases the heat transfer efficiency and tends to equalize temperature gradients in a body in contact with the apparatus. The apparatus is utilized in various locations in an electrophotographic printing machine and can be used as a pressure roll for a heat and pressure fuser, a support or drive roll for a photoreceptive member, a support member for a photoreceptor and a heat sink for a developer housing.

Isothermalizing member for a printing machine

A printing machine of the type having a plurality of components for printing a document is disclosed. The printing machine includes an air source and a support member having a component mounted thereon. The support member is coupled to the air source which has output ports so that air flows from the output ports.

Apparatus for distributing air flow in a printing machine

A device which electrically grounds a component. The device includes a support member having a multiplicity of fibers mounted thereon. The support member has a plurality of spaced regions of reduced thickness to facilitate the breaking thereof. In this manner, a user may select a grounding device of any desired length.

Grounding brush

An electrophotographic printing machine and method of use therefor in which a first image having a density less than that of the original document being reproduced is formed on a sheet of support material. A half-tone image having substantially the density of the original document is reproduced, in superimposed registration with the first image, on the sheet of support material. This produces a high quality copy having substantially the density of the original document.
