摘要： A registration and measurement system for a printing machine includes two drive rollers and two opposing idler rollers. Each drive roller and idle roller combination respectively form a drive nip. A single servo or stepper motor is operably connected to the drive rollers through a gear train, allowing the motor to drive the sheet feeding nips. A rotary encoder is attached to each idler roller. Optical sensors are provided above a desired sheet path. The optical sensors and the rotary encoders are connected to a controller and are operable to deliver output signals to the controller. The controller is operable to determine the length of a sheet passing through the nips based upon the signals received from the optical sensors and the rotary encoders.

摘要： A sheet handling system comprising a sheet registration system having sheet registration nips and a receiving system for a sheet including a capturing point for engaging said sheet. Auxiliary nips are positioned between the sheet registration nips and the receiving station. The auxiliary nips are moveable between an open and closed position. A controller receives a signal indicative of the length of said sheet and sends a signal to the auxiliary nips to be in a sheet engaging position when the length of the sheet is less than the distance between the sheet feeding nips and the capturing point of said receiving station and be in an open position if the length of said sheet is greater than the distance between the sheet registration nips and the capturing point of said receiving station. In another embodiment, the auxiliary nips are maintained in their open position until the trailing edge of a sheet is about to leave the sheet registration nips, at which point the auxiliary nips are closed.

摘要： A multi-color electrophotographic printing machine in which the tangential velocity of the photoconductive drum in the transfer zone is greater than the tangential velocity of the transfer drum having the sheet receiving the transferred images thereon. A buckle is formed in the sheet after the transfer zone, resulting in the sheet being tacked to the developed image on the photoconductive member and moving at the same tangential velocity as the developed image. This is achieved by a transfer sheet having one end secured fixedly over an aperture in the transfer drum. The other end of the transfer sheet is resiliently secured to the transfer drum. The sheet of support material receiving the transferred images is secured at the leading edge to the transfer sheet. In this way, the transfer sheet and the sheet of support material may be induced to form a buckle after the transfer zone enabling the sheet of support material and the developed image to move at the same tangential velocity. By moving at the same tangential velocity, the image smear is eliminated during transfer.

摘要： A droplet-on-demand ink jet printer uses electrostatic tacking of a recording medium, such as paper, to achieve simultaneously precise holding of an aligned recording medium on a dielectric surface of a transport belt, thereby providing precise motion quality of the recording medium relative to the printer's printhead, and improved ink droplet placement on the recording medium. The transport belt is electrostatically charged with a charge of one polarity, so that an electrostatic pressure is generated which precisely holds the recording medium in an aligned position on the transport belt, after it is fed thereon, and concurrently induces a charge of opposite polarity on the ink droplets ejected by the printhead, thereby accelerating the droplets toward the recording medium. The accelerated droplets reduce transverse forces on the droplets, such as transverse airflows, and placement errors caused by the repulsion of incoming droplets by previously printed images are further reduced by migration of the charges of the printed droplets through the recording medium and consequent charge cancellation, so that droplet placement is improved.
摘要翻译：液滴按需喷墨打印机使用记录介质（例如纸）的静电贴合来实现对准的记录介质在输送带的电介质表面上的精确保持，从而提供记录介质相对的精确的运动质量到打印机的打印头，并改善墨滴在记录介质上的位置。输送带带有一个极性的电荷静电，从而产生静电压力，将静电压力精确地保持在输送带上的对准位置上，然后再将其输送到相对极性的电荷上墨滴由打印头喷射，从而将液滴加速到记录介质。加速的液滴减小液滴上的横向力，例如横向气流，并且通过预先打印的图像对进入的液滴的排斥引起的放置误差进一步减小，通过印刷液滴的电荷通过记录介质迁移并导致电荷消除，从而提高了液滴的位置。

摘要： An apparatus and method for registering and deskewing a sheet along a sheet path. A pair of drive spheres are located in the sheet path. When a sheet enters the nips formed by the spheres the sheet is driven until it is sensed by a sensor. The drive spheres are driven by a pair of wheels which allow the spheres to rotate about any axis through their center and parallel to the plane of the sheet. The spheres are driven such that the sheet is side registered and deskewed as it is moved along the sheet path. Constant feedback from the sensors to the drive controller allows the sheet to be registered in a very short distance and has the added benefit of self compensation for wear of the drive components. The wide registration and deskewing latitude of the device allows for the use of relatively inexpensive and low accuracy sheet drives preceding the device.
摘要翻译：一种用于沿片材路径对片材进行登记和偏斜的装置和方法。一对驱动球位于片材路径中。当纸张进入由球形成的胶片时，片材被驱动，直到被传感器感测到。驱动球由一对轮驱动，这些轮允许球围绕其中心并平行于片的平面绕任何轴线旋转。驱动球体，使得片材沿着片材路径移动时被侧向对准并进行歪斜校正。从传感器到驱动控制器的恒定反馈允许纸张在非常短的距离内进行记录，并且具有对驱动部件磨损的自我补偿的附加益处。该设备的广泛配准和偏移校正纬度允许在设备之前使用相对便宜且低精度的片式驱动器。

摘要： According to aspects illustrated herein, there are provided methods and systems for applying continuous tension on a belt/cable system. The automatic tensioning system includes a pivot mechanism and a locking mechanism. The pivot mechanism includes a pivot arm extending between an idler pulley and a pivot point. The idler pulley is mateable with a belt/cable. The belt/cable is routed about the idler pulley. The idler pulley rotates by the movement of the belt/cable, and the pivot arm pivots in an opposing direction from the belt/cable at the pivot point to apply continuous tension to the belt/cable as the pivot arm pivots. The locking mechanism is in communication with the pivot arm to secure the pivot arm in position, and the locking mechanism is adjustable.
