摘要： A method of calibrating once-around and harmonic errors of encoded nips is provided. An encoder with an index pulse is used to measure the velocity and rotation of the driven wheel or idler. The geometry of the drive train and wheel and idler is chosen so that their once around and harmonic frequencies are unique such that no other drive errors will generate these frequencies. The method includes running the idler or wheel at substantially constant velocity for N revolutions. Each index triggers the collection of velocity data, which is averaged for N revolutions. This process detects drive train motion errors that are periodic with respect to the timing of the index pulse (i.e., once per revolution of the wheel or idler). Once the velocity errors have been measured, corrections are made. This method may be incorporated in xerographic machines as part of a setup or calibration procedure.
摘要翻译：提供了一次校准和编码压区的谐波误差的方法。具有索引脉冲的编码器用于测量从动轮或惰轮的速度和转速。选择传动系和轮和惰轮的几何形状，使得它们的一次和谐频率是唯一的，使得没有其他驱动误差将产生这些频率。该方法包括以大致恒定的速度运行惰轮或轮子进行N转。每个索引触发速度数据的采集，这是N转的平均值。该过程检测相对于索引脉冲的定时周期性的驱动系运动误差（即，轮或惰轮每转一次）。一旦测量出速度误差，就进行校正。该方法可以作为设置或校准过程的一部分并入静电印刷机中。

摘要： An electrostatographic and/or xerographic machine includes a media path adapted to move a media sheet. Sensors are positioned adjacent the media path. The media sheet has a leading edge and a trailing edge and the sensors are adapted to identify locations of the leading edge and the trailing edge of the media sheet. A marking device is positioned adjacent the media path. The marking device is adapted to print first items on a first side of the media sheet and print second items on a second side of the media sheet. A registration controller is operatively connected to the media path and to the sensors. The registration controller determines a length between the leading edge and the trailing edge of the media sheet using output from the sensors, and determines the parallelism between the leading edge and the trailing edge of the media sheet using output from the sensors. The registration controller calculates a registration correction factor based upon the length and the parallelism and corrects the alignment of the first items printed on the first side of the media sheet with the second items printed on the second side of the media sheet using the registration correction factor.

摘要： A method of registering sheets laterally and in skew enables active sheet deskew without translating the sheet in the cross-process direction. A sensor carriage position is controlled to find the sheet edge after which deskew control can start. The average value of the carriage position can then be fed in a feedforward manner to move the image location to match the average paper position. This achieves good average lateral registration and active skew control at a reduced cost.

摘要： Parallel printing systems and methods incorporate inverter assemblies for not only inverting media during transport through the system but also to register the media or provide a velocity buffer transports with different drive velocities. The inverter assemblies can include the capability to optionally deskew the media and provide lateral registration corrections. The inverter assembly nip rollers are sufficiently spaced from process drive nip rollers to decouple a document in the inverter assembly from the highway paths. The method comprises combining the inverting function selectively with either the registering or the velocity buffering functions.

摘要： Color electrophotographic printers having latent image positions synchronized with start-of-scan signals. A laser source projects a laser beam onto a multifaceted rotating polygon that sweeps that beam in a scan line across a moving photoreceptor. A start-of-scan detector produces start-of-scan signals when the laser beam is in position to write a scan line. A belt sensor produces belt signals when indicia on the photoreceptor passes a reference position. A controller receives the belt signals and the start-of-scan and then adjusts the photoreceptors rotational velocity such that the belt signals are an integral multiple of the start-of-scan signals. To reduce the impact of drive roller eccentricities on belt signal to start-of-scan signal timing, the perimeters of photoreceptor roller elements are sub-multiples of the photoreceptor length.

摘要： A method and apparatus for simultaneously developing and transferring a liquid toner image. The method includes the steps of moving a photoreceptor including a charge bearing surface having a first electrical potential, applying a uniform layer of charge having a second electrical potential onto the charge bearing surface, and imagewise dissipating charge from selected portions on the charge bearing surface to form a latent image electrostatically, such that the charge-dissipated portions of the charge bearing surface have the first electrical potential of the charge bearing surface. The method also includes the steps of moving an intermediate transfer member biased to a third electrical potential that lies between said first and said second potentials, into a nip forming relationship with the moving imaging member to form a process nip. The method further includes the step of introducing charged liquid toner, having a fourth electrical potential, into the process nip, such that liquid toner sandwiched within the nip simultaneously develops image portions of the latent image onto the intermediate transfer member, and background portions of the latent image onto the charge bearing surface of the photoreceptor.
