Abstract: An apparatus which develops a latent image with marking particles. The apparatus includes a developer roller which transports the marking particles closely adjacent to the latent image. As the marking particles are deposited on the latent image, the developer roller senses the charge thereon. In response to the sensed charge of the marking particles, additional marking particles are dispensed into the chamber of the housing for subsequent use by the developer roller.

Abstract: Ein dreidimensionaler Gegenstandsdrucker ist so ausgelegt, dass er ermöglicht, dass die Dichte des Materials, das von mindestens einem Druckkopf auf eine sich drehende Trägerplatte nahe an deren umlaufenden Kante ausgestoßen wird, in etwa die gleiche ist wie die Dichte des Materials, das auf der sich drehenden Trägerplatte nahe dem Mittelpunkt der Trägerplatte ausgestoßen wir.

Abstract: A system and method is provided for compensating for a faulty ink jet in a target printhead in an ink jet imaging system having a plurality of printheads arranged to span a maximum printing width that includes defining a typical printing width less than the maximum printing width and swapping the target printhead with a printhead situated in the margin outside the typical printing width. The system and method permits swapping the target printhead with a margin printhead that has a faulty ink jet provided that the location of the faulty ink jet in the margin printhead does not coincide or align with a faulty ink jet in printheads adjacent the target printhead.

Abstract: Se proporciona un sistema y método para compensar un chorro de tinta fallido de una cabeza de impresión blanco en un sistema de formación de imágenes de chorro de tinta que tiene una pluralidad de cabezas de impresión arregladas para abarcar un ancho de impresión máximo que incluye definir un ancho de impresión típico menor que el ancho de impresión máximo y reemplazar la cabeza de impresión objetivo con una cabeza de impresión situada en el margen fuera del ancho de impresión típico. El sistema y método permite reemplazar la cabeza de impresión blanco por una cabeza de impresión de margen que tiene un chorro de tinta fallido siempre que la ubicación del chorro de tinta fallido en la cabeza de impresión de margen no coincida o se alinee con el chorro de tinta fallido en las cabezas de impresión adyacentes a la cabeza de impresión blanco.

Abstract: Ein Verfahren zum Betreiben eines Druckers ermöglicht es, dass Kompensationsparameter erzeugt und in Verbindung mit Systemzuständen gespeichert werden, die zum Zeitpunkt der Kompensationsparametererzeugung erfasst werden. Beim Erkennen entsprechender Systembedingungen zu einem späteren Zeitpunkt ist der Drucker in der Lage, die zuvor erzeugten und gespeicherten Kompensationsparameter zu verwenden, um damit die Zeitsteuerung von Druckkopfauswurfeinrichtungen einzustellen, so dass die Justierung von Tintenbildern, die durch das System erzeugt werden, verbessert wird.

Abstract: An acoustic scavengeless assist (ASA) development apparatus (40, 42, 44), forms part of a multicolor image reproduction machine (Fig. 1). The (ASA) development apparatus includes a biased vibratory section (46) having a piezoelectric member (85) and a donor member (88), as well as, a development electrode section (59), for presenting toner particles to latent electrostatic images for image development. The donor member (88) is positioned within the reproduction machine and forms a development nip with a latent image bearing surface (10) of a photoreceptor of the reproduction machine. Importantly, the biased vibratory section has at least a first conductive electrode (67) formed therein adjacent to said piezoelectric member (85) for effecting controlled vibratory toner release from the donor member (88), and a first bias for biasing the at least first conductive electrode. The development electrode section includes a set of second conductive electrodes (66) and a second bias (70) therefor, and is located between the at least first electrode (67) and the latent image bearing surface (10), for enhancing toner particle release from the donor member (88), and powder cloud formation within the development nip for quality image development.

Abstract: This invention provides for duplex use of densitometers. An image is produced on a substrate, that substrate is brought back through the transfer station in a duplex fashion (that is, the substrate is inverted), and a sensor senses the image on the substrate. Beneficially, the sensor senses one or more parameters such as color registration, color occlusion/interference, black separation in color REaD printing, colorimetry, and the overall transfer and fusing process; and a printing process is controlled based on the sensed parameters.

Abstract: A multistation color electrophotographic printer having an erase lamp (39) located opposed to or before the last physical developer housing (32), but after the first physical developer housing (28). The erase lamp (39) is also on the opposite side of the photoreceptor (10) from the development stations (28,30,32,34).

Abstract: The present invention is an apparatus that develops a latent image recorded on a surface with toner. An electrically biased electrode member in the development zone between the photoconductive member and the donor roll detaches toners from the donor roll so as to form a toner powder cloud in the development zone. The electrical bias applied on the donor member is an asymmetrical wave. Toner from the toner powder cloud develops the latent image.
