摘要： A method and apparatus for controlling speed match between a photoreceptor and an intermediate transfer member to prevent image degradation by creating a deliberate speed mismatch. It has been found that slight variations in speed match between a photoreceptor and transfer member will maintain acceptable image quality, however, should the relative velocity between the members change sign, unacceptable image error results. The method herein comprises slewing the velocity of a photoreceptive member over a range of speeds while monitoring the output control signal current of a drive motor. The resulting control signal current has a large oscillation at the velocity at which the speed of the photoreceptor matches that of the intermediate transfer member. A controller is then used to maintain the motor velocity at a speed slightly less than or slightly greater than the intermediate transfer member speed so as to prevent a change in sign of the relative velocity between the two moving surfaces.

摘要： The method and apparatus for measuring the particle concentration in a fluid that is passed between a reciprocally movable window and a single photodetector. A collimated beam of light is directed through the window and fluid to the photodetector. The window is moved from a first predetermined location to a second predetermined location to vary the light beam path length, thus enabling at least two different photodetector output signals. The ratio of the two signals provides the data needed to determine the particle concentration in the fluid.

摘要： A quad-roll curler apparatus includes a first roll, a second roll, a third roll, and a fourth roll. The curler apparatus is adjustable to a first processing configuration wherein three of the four rolls are engaged to impart a curl in a sheet in a first direction. The curler apparatus is adjustable to a second sheet processing configuration wherein three of the four rolls are engaged to impart a curl in a sheet in a second direction that is different from the first direction.

摘要： A method and apparatus is provided for controlling the transverse registration of an image area to be exposed on a longitudinally moving belt by providing belt edge profile data, detecting a lateral position of the belt during movement of the belt by measuring the lateral position of the belt edge, and adjusting the transverse location of the image on the belt to compensate for a difference between the detected lateral belt edge position and the belt edge profile data. In addition, a method and apparatus is provided for controlling the lateral position of a longitudinally moving endless belt by generating a steering command signal by calculating a difference between the detected first lateral position of the belt edge and the belt edge profile data corresponding to the first longitudinal position, and adjusting the lateral position of the belt by steering the belt in response to the steering command.
