摘要： The present disclosure relates to a fusing system for fusing toner to a recording medium. The fusing system includes a fuser roller including a metal layer, a pressure roller in contact with the fuser roller, and an external induction heating element. In addition, the disclosure relates to a method for heating a fuser roller of a fusing system including the steps of positioning an external induction heating element in close proximity to the outer surface of the fuser roller, delivering high frequency current to a coil of the external induction heating element to create a magnetic flux, and directing the magnetic flux toward the fuser roller so as to induce eddy currents within a metal layer of the fuser roller that generate heat within the roller.

摘要： A temperature differential over a length of a fuser can result from a thermal load applied to the fuser by media having a dimension, corresponding to a longitudinal axis of the fuser, less then the length of the fuser. The temperature on regions of the surface of the fuser contacting the media is lower than on regions of the surface not contacting the media. With feedback used to control the fuser surface temperature near its center, the fuser surface temperature in regions not contacting the media can become hot enough to damage the fuser. With a heat pipe included in the fuser, heat flows from the higher temperature regions on the surface of the fuser to the lower temperature regions on the surface of the fuser, thereby reducing the peak magnitude of the fuser surface temperature and the magnitude of the temperature differential over the length of the fuser.

摘要： Hot offset of black toner is reduced or eliminated in a color electrophotographic imaging device, such as a laser printer, by applying a minimal layer of non-black toner in addition to the black toner on a print media. The non-black toner, such as cyan, magenta or yellow toner, acts as a release agent for reducing or eliminating hot offset of the black toner during fusing of the toner to the media. The non-black toner is applied as a thin layer just sufficient to reduce hot offset of the black toner and such that an appearance of a resultant image formed retains a visual perception of being a black toner only image. In an alternate embodiment, the thin layer of non-black toner is applied in response to coated media being processed, such as overhead transparencies, that are more susceptible to hot offset. In yet a further alternate embodiment, raster source image data is converted to output data using a process neutral axis color rendering table, and vector source image data is converted to output data using the same process neutral axis color rendering table only if coated media is being processed, thereby reducing hot offset of black toner. Otherwise, the vector source image data is converted to output data using a black only neutral axis color rendering table.
摘要翻译：除了黑色调色剂之外，通过在打印介质上施加除黑色调色剂之外的最小层黑色调色剂，也可以在诸如激光打印机的彩色电子照相成像装置中减少或消除黑色调色剂的热偏移。非调色剂如青色，洋红色或黄色调色剂起着降低或消除将调色剂熔合到介质中的黑色调色剂热偏移的脱模剂的作用。非黑色调色剂作为薄层施加，足以减少黑色调色剂的热偏移，并且使得形成的所得图像的外观保持作为仅黑色调色剂图像的视觉感知。在替代实施例中，响应于被加工的涂覆介质（例如架空透明胶片），更易受热偏移的影响而施加薄层的非黑色调色剂。在另一替代实施例中，光栅源图像数据使用过程中性轴颜色再现表转换为输出数据，并且仅当涂覆介质正在被使用时，使用相同的过程中性轴显色表将矢量源图像数据转换为输出数据加工，从而减少黑色调色剂的热偏移。否则，使用仅黑色中性轴显色表将矢量源图像数据转换为输出数据。

摘要： A single pass color printer employs a band drive to move media sheets through plural developer stations. The band drive also provides motive power to drive, in common (via frictional engagement with their respective peripheries), all of the organic photoconductor (OPC) rollers that are present in plural developer stations that are arrayed along the media movement path. The use of the common band drive assures that the surface speeds of the OPC drums and media sheets are synchronized at their respective points of contact, thus eliminating much of the station to station variations due to differences in diameters and runout of the plural OPC rollers.

摘要： A method of aligning duplex images on an imaging device such as a printer or copier includes duplex imaging a test sheet having indicia on each side of the sheet that communicate, when observed in a single visual context, duplex imaging adjustment parameters for the imaging device. The method further includes modifying imaging parameters of the imaging device based on the duplex imaging adjustment parameters communicated. The indicia on each side of the sheet are seen in a single visual context by observing certain of the indicia through the media, as when the media is held up to a light source. In a preferred embodiment, the indicia on each side of the sheet includes respective portions of a vernier scale. The imaging parameters are modified by entering the adjustment parameters at a control panel of the imaging device. Imaging parameters modified include timing parameters associated with the process of writing data on the imaging device. In addition to the method, an imaging device includes components, data and executable instructions necessary for implementing the above described method.

摘要： An electrostatic imaging system includes a photoconductor which carries an image defined by a liquid toner. The liquid toner comprises a pigment binder system in a paraffinic solvent blend carrier liquid, the liquid carrier exhibiting a relatively high flash point temperature. The imaging system further includes a heating roll, and a film forming roll positioned between the photoconductor and the heating roll. The film forming roll includes at least first and second superposed layers, the first layer comprised of a material that is carrier liquid phillic and which exhibits a dimensional thickness which enables substantially all carrier liquid entrained therein to reach the liquid's flashpoint temperature when under influence of the heating roll. The second layer is carrier liquid phobic and exhibits a resiliency that enables the first layer to compliantly mate with the photoconductor surface. A further transfer roll comprises an outer, liquid carrier phobic layer and an inner compliant layer for enabling indirect transfer of an image from the photoconductor to a media sheet.

摘要： An intake manifold arrangement for internal combustion engines whereby the combustion chamber can be supercharged without the use of mechanical gears and/or pumps. A pressure chamber is mounted upon the combustion chamber and communicates with the combustion chamber and an air and fuel mixture supply. A check valve for selectively allowing the mixture to enter the pressure chamber is provided between the air and fuel supply and the pressure chamber. An intake valve for providing selective communication between the pressure chamber and the combustion chamber is provided and controlled by the compression ratio control mechanism. The compression ratio control mechanism includes an axially slidable cam having a lifting surface of greater duration axially at one end of the cam than the other end of the cam. The cam is selectively axially shifted by an accelerator pedal which controls a hydraulic piston coupled to the cam. The intake valve is opened during the intake stroke and the mixture is drawn into the combustion chamber. The pressure chamber is pressurized during the compression stroke while the intake valve is open and the compression ratio in the combustion chamber is selectively controlled by closing the intake valve at a point during the compression stroke by the selectively slidable cam. An exhaust boost or scavenging arrangement is provided whereby pressurized air is selectively forced into the combustion chamber.

摘要： A mechanism is described for automatically handling envelopes and paper sheets, the mechanism having an input window for receiving the envelopes and paper sheets. The mechanism comprises a first tray for holding a stack of paper sheets and is mountable in the window. A second tray is provided for holding a stack of envelopes and is also mountable in the window. A roller system is positioned to selectively engage the topmost sheet of the stack of sheets in the first tray or a bottommost envelope of the stack of envelopes in the second tray and to feed either the topmost sheet or the bottommost envelope, as the case may be.
