摘要： A media transport apparatus and method includes a first media transport having a first drive unit, configured and operative to convey the substrate media through a marking zone to be marked by a print head. A first motion encoder is operatively connected with the first media transport, configured and operative to output a first signal dependent upon the motion of the first media transport surface. A second media transport with a second drive unit and second motion encoder is configured and operative to receive the substrate media from the first media transport and to convey the substrate media. The second drive unit drives the motion of the second media transport with substantially the same surface velocity as the first media transport. The first and second media transports are each operative to hold the substrate media in contact therewith, with respective first and second hold-down forces that may be different magnitudes, including the first hold down force of the first media transport having a greater magnitude than the second hold down force of the second media transport while the substrate media is at least partially within the marking zone and is subjected to both the first and second hold down forces.

摘要： A method and system for insuring printing accuracy in simplex imaging or duplex imaging, including a media sheet in a media path adapted to move the media sheet through the system. The media path includes sensors and a datum. The sensors include a leading edge sensor and a trailing edge sensor adapted to record the time of arrival of the edge. The edge arrival time difference is determined between the arrival time of the edge using output from the trailing edge sensor and the arrival time of the edge using output from the leading edge sensor. A correction factor is based upon the time difference. The time of arrival of the media sheet at the datum is determined using the correction factor to align items printed on both side of the media sheet.

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.
