摘要： A color electrophotographic apparatus which can achieve full color image reproduction with one-pass developing is disclosed. According to the present invention, a flexible photoconductor is formed as an endless belt driven by a set of rollers. Developers of various colors are projected onto a surface of the photoconductor from a plurality of developing units. After the projection of the color developers is achieved, the resultant full color toner image is transferred to a recording medium. The toner image is then fused onto the recording medium, thereby reproducing the full color image. The flexible photoconductor is arranged to have a planar surface between the two rollers, with the four optical exposure units positioned to direct four parallel beams of light in a direction perpendicular to the planar printing surface of the photoconductor. Each of the aligned exposure units have an associated line memory register and at least one shift register for horizontally aligning the lines of information from each exposure unit.

摘要： A developing unit includes a housing enclosing a mesh belt stretched across first and second rollers. The belt passes between a pair of friction plates that can be used to tribocharge toner particles carries on the mesh belt. Charging occurs over the large width of the entire mesh belt and the friction plates. Toner is transported on the surface of the mesh belt to a developing roller which, in turn, transports the toner to the surface of a photoconductor. The configuration of this developing unit reduces the loading associated with the tribocharging operation and the belt transport system reduces the volume of the developing unit.

摘要： A method for analyzing a print/copy job is disclosed. In this method, an actual page count of a print/copy job is recorded, and a total toner coverage for the print/copy job is compiled. Then, a total toner coverage page count is obtained via a computation using a predetermined threshold value and the total toner coverage, wherein the predetermined threshold value is an amount of a toner coverage for a print/copy page under normal fare, and when the actual page count of the print/copy job is less than the total toner coverage page count, a toner coverage adjustment page count is equal to the total toner coverage page count. Thereafter, a report is produced in accordance with the print/copy job.

摘要： An imaging system includes an imaging subsystem for forming an image on a sheet, a tray for holding a supply of sheets, a ramp for directing a sheet from the tray into a paper path, a sensor in the vicinity of the paper path, a drive assembly and a processor connected to the drive assembly and the sensor. The drive assembly includes a movable roller configured to move the sheet into the paper path by moving a top sheet of a supply of sheets in the tray to the ramp. The sensor is configured to detect a sheet traveling in the paper path from the tray and to provide an output signal in response to the detection. The processor is configured to control movement of the roller, to receive and store an initial sheet level value, to receive the output signal from the sensor and to calculate a time, t, from activating the drive assembly to receiving the sensor output signal and to accordingly adjust the initial sheet level value. In a method for measuring sheet levels in an imaging system paper tray, a start time that a roller engages a paper sheet to feed the sheet from the paper tray to a paper path of the imaging system is recorded and a time the sheet passes a location along the paper path is sensed. A time difference between the start time and the time sensed is processed to provide a signal that represents a supply of sheets in the paper tray.

摘要： An upgradeable imaging system includes a housing with an opening. A support structure and a plurality of imaging stations are disposed within the housing. Each imaging station includes a charging unit and a developing unit. The imaging system also includes a removable module with a photoreceptive substrate. The removable module has an interior space defined within the photoreceptive substrate and at least one exposing unit disposed within the interior space. The removable module is configured to be engageable with the support structure and passable through the opening of the housing. When the removable module is engaged with the support structure, the photoreceptive substrate is disposed operatively adjacent to the imaging stations. Accordingly, the removable module may be removed from the imaging system and replaced with another module. The imaging system includes circuitry for configuring the imaging stations to operate according to a printing routine depending upon the number of exposing units.
