Communication device includes a housing with a two or more apertures defined therein to form a speaker grille. The apertures are arranged to form one or more aperture sets, each comprised of at least two apertures connected by a fluid channel defined on an internal face of the panel. The fluid channel is comprised of one or more channel segments. Each of the channels segments and the acoustic apertures has a predetermined size and shape which draws fluid through the apertures from an exterior side of the panel, to an interior side of the panel, and then into one of the channel segments. The dimensions and geometry of the channels and apertures are selected to cause the fluid in the channels to exit from the housing at a lowermost one of the acoustic apertures.

A cleaning brush for use in an electrostatographic imaging apparatus, including a plurality of individual electrically conductive fibers secured to a brush core and having fiber tips relatively remote from the brush core, wherein the cleaning brush includes an electrically conductive plane at a surface of the brush core, or between a surface of the brush core and the electrically conductive fibers, effective for inducing an electrical potential to the conductive fibers when an electrical potential is applied to the electrically conductive plane, and at least one of a relatively non-conductive layer electrically insulating the conductive plane from the conductive fibers, or electrically insulating coatings on tips of the electrically conductive fibers remote from the brush core. The insulative, or non-conductive, layer between the fibers and the conductive plane of the brush prevent excessive current draw.

The present invention provides a method of printing which includes providing a substrate having an inked surface. The inked surface is typically achieved using an offset lithographic printing press. A thermoplastic polymer powder is applied to the inked surface. The surface is then fused. An advantage of the prepared substrate is that there is reduced contamination of electrostatographic fusing systems when fused by heat and pressure fixing. Another aspect of the invention further provides a method of fusing a substrate having an inked surface wherein a thermoplastic powder has been applied to the inked surface prior to stacking the uncured offset prints.

The fuser roller and heater rollers of the fusing system can become contaminated with ink and other foreign material when pre-printed materials are run through them. The contamination can create regions of cold spots, which in turn results in poor fusing. Other image defects may result. According the various aspects of the invention, a heater roller cleaner, method and apparatus are provided for applying an array of differential pressure generating areas to a heater roller surface in a fuser assembly while rotating the heater roller surface.

Heater roller cleaner, method and apparatus for a fuser assembly

A method of printing comprising the steps of marking the surface of a test preprinted media with a first marking material; placing the media adjacent to a transfer media; disposing the test media and the transfer media into the nip of a fuser roller assembly to thereby apply predetermined heat and pressure thereto; removing the test media and the transfer media from the nip of the fuser roller after a predetermined time; and, measuring the density of the first marking material which has been offset to the transfer media.

A toner level detector assembly includes an electrically conductive container body that defines a container cavity and an orifice. A sensor assembly includes a holder and a probe. The holder is sealingly associated with the orifice. The probe is disposed within the holder. The holder electrically isolates the probe from the container body. The probe senses a level of material within the container cavity.

This invention provides an image-forming machine with a conditioned cleaning system, which may have a photoconductor, one or more chargers, a toning station, and a cleaning station. Toner is applied to image areas and toner lubrication areas on the photoconductor. The toner essentially provides a lubricating or protective barrier between the cleaning station and the photoconductor.

The invention relates to cleaning systems for electrographic processes and, in particular, to detecting leaks in such processes. A process and apparatus for sensing leaks is provided in an electrographic process cleaning system of the type configured to have a particle collection container. According to an aspect of the invention, a pressure is sensed that is indicative of pressure inside the particle collection container.

An integrated environmental management system for reproduction apparatus including a reprographic marking engine for reproducing information supplied thereto and accessories for facilitating the handling of reproduction output from the marking engine. The integrated environmental management system includes a housing associated with the reprographic marking engine. The housing defines a chamber having, in communication, a rear wall substantially parallel to the rear of the reprographic marking engine, first and second side walls, and top and bottom walls. An inlet plenum in the housing chamber communicates, for example, with an opening in the first side wall of the housing. The inlet plenum includes an inlet filter for preventing contaminants in ambient air from entering the inlet plenum, a first inlet duct directed into the general interior of the reprographic marking engine, and a plurality of inlet ducts directed respectively to specific systems within the reprographic marking engine. An exhaust plenum in the housing chamber communicates, for example, with an opening in the second side wall of the housing. The exhaust plenum includes a first exhaust duct directed from the general interior of the reprographic marking engine, a plurality of exhaust ducts directed respectively from specific systems within the reprographic marking engine, and a filter for preventing contaminants carried by air flow from within the reprographic marking engine from exiting through the exhaust plenum. At least one fan is provided for moving air from the inlet plenum through the reprographic marking engine and through the exhaust plenum. The fan has a control for regulating the speed thereof to maintain a desired air flow for a given power output of the reprographic marking engine.
