摘要： Development stations are provided. In one aspect, a development station has a housing having a recirculation path an auger being rotatable to move the developer along at least part of the recirculation path. A drive transmission has a first output mechanically linked for movement with a first end of the auger and a second output mechanically linked for movement with a second end of the auger and distributes a force at an input end between a first force provided at the first output and at a second force provided at the second output to rotate the auger against a drag. The first force and the second force are less than a third force to drive an alternative auger from a driven end. The auger has a first end yield strength and a second end yield strength that are each less than a driven end yield strength of the alternative auger.

摘要： Development stations are provided. In one aspect a development station has a housing having a recirculation path and an auger being rotatable to move the developer along at least part of the recirculation path. A first actuator drives a first end of the auger and a second actuator drives a second end. A first sensor senses a rotational position of the first end while a second sensor senses a rotational position of the second end of the auger. An auger controller causes the actuators to act so that a first force and a second force rotate the auger against a drag. The first force and the second force are less than a third force to drive an alternative auger from a driven end. The auger has a first end yield strength and a second end yield strength that are less than a driven end yield strength of the alternative auger.

摘要： A piezoelectric crystal adjacent to a development member in an electrophotographic printer has an electrode on it facing the development member. An AC bias is applied across the crystal while a DC bias is applied between the electrode and the development member to measure toner-mass deposition rate. An AC bias is then applied between the electrode and the development member to measure developer flow rate. The toner concentration of the developer is determined using the measured toner mass-deposition rate and developer flow rate.

摘要： Printers are provided. In one aspect, a printer has a printer controller cooperating with a print engine, receiver transport system, overlap positioning system, and fuser to cause a first toner image to be formed on the first side of the first receiver with toner at least in an overlap area proximate to a first edge of the first receiver; to overlap the first edge of the first receiver with a second edge of the second receiver having a second thickness at a second end and to fuse the overlapped first receiver and second receiver to cause the toner in the overlap area to bond the first receiver to the second receiver. The first toner image includes an edge concealment toner pattern positioned confronting the second edge with the edge concealment toner pattern having toner that reduces the visual impact of image artifacts created by the overlapping second edge.

摘要： Method and apparatus for printing an image-wise ink pattern on a receiver. A primary imaging member includes a series of substantially equal-sized cells located over the substrate surface thereof. The primary imaging member has an electrically conductive layer. An ink jet printhead selectively ejects drops of ink into the primary imaging member cells in a desired image-wise ink pattern. The image-wise ink on the primary imaging member is fractionated to separate the liquid in the ink. A receiver is transported into operative association with the primary imaging member, and a transfer mechanism applies a pressure between the receiver and the primary imaging member, and establishes an electrostatic field to transfer the image-wise ink pattern to the receiver.

The toner includes toner particles having a diameter of between 4 and 10 microns and transfer assisting particles appended to the toner particles surface. The transfer assisting particles have a diameter of between 20 and 100 nm. The toner image is transferred from the primary image member to an intermediate image member having an overcoat layer, the overcoat layer having a Young's modulus of from 250 to 500 MPa. The toner image is transferred from the intermediate image member to a receiving sheet wherein the intermediate image member drives the primary image member or the receiving sheet.

摘要： A process for reducing image defects in an electrostatographic image resulting from particulate contamination. A primary imaging member, including a photoconductive element and an outermost layer of silicon carbide, is uniformly charged in an electrostatographic imaging apparatus subject to particulate contamination. The electrostatographic imaging apparatus includes a charging station, an exposing station, at least one developing station, and a transfer station comprising an electrically biased roller transfer assembly. The primary imaging member is exposed imagewise at the exposing station to form a latent image on the imaging member, which is thereafter developed with toner at the developing station to form a developed image on the imaging member. The primary imaging member bearing the developed image is passed through a charge erasing station to remove residual surface charge, then contacted with a receiver by the electrically biased roller transfer assembly, causing the developed image to transfer to the receiver. The silicon carbide layer protects the photoconductive element against damage by contaminant particles present in the apparatus.
