    摘要： Document processing systems and methods are presented in which one or more pages of a print job are segmented into two or more parts, with the first part being transferred and affixed to the printed medium prior to transferring and affixing the second part, in order to facilitate high TMA (pile height) printing while mitigating adverse retransfer, blur, fusing, and hollow character effects.

    摘要： A method and apparatus can, while operating a printing device in a test mode, supply a changed transfer field to a marking material transfer device. The changed transfer field is less than or more than the standard transfer field. The method and apparatus disable operations of other marking material transfer devices of the printing device to isolate the marking material transfer device. Further, the method and apparatus compare the actual amount and/or spatial distribution of marking material transferred to a recipient surface (to which the first marking material transfer device transfers the marking material) against a predetermined standard. Then, if the actual amount of marking material transferred to the recipient surface is different than the predetermined standard, the method and apparatus can identify the first marking material transfer device as being a potential source of printing defects.

    摘要： Electrodes are embedded in a biased transfer roller for the transfer of a xerographic image. The electrodes, which run the length of the roller, are deposited on an insulating core surrounding the shaft. A conformable semi-conductive layer of a flexible elastomer covers the embedded electrodes. The semi-conductive layer limits current flow between embedded electrodes, relaxes charge deposited on the roller surface, and maximizes the electric field that attracts the toner from the photoconductor to the image receiving surface (substrate or intermediate). The electroded biased transfer roller may tailor the electric fields within the nip, pre-nip, and post-nip regions between the photoreceptor and the image receiving surface of the xerographic device.

    摘要： An electrostatographic printing apparatus that includes a charge receptor endless belt; a transfer nip including a BTR roll in contact with the charge receptor at a transfer zone, a continuous media supplied to the transfer zone, and the transfer nip adapted for systematic engagement and disengagement with the continuous media for synchronization of image transfer from the charge receptor to the media. More specifically, in response to recognition of imaging inconsistencies such as belt seams, test patches, or label format pitches, the endless belt disengages from the continuous media at the BTR roll. The BTR roll is appropriately turned on and off and the continuous media reversed in direction commonly known as a ‘Pilgrim step’, then returned to normal direction to synchronize the transfer of images to the continuous media.

    摘要： Electrodes are embedded in a biased charge roller of a xerographic device. The electrodes, which may run the length of the roller, are deposited on an insulating substrate. A semi-conductive conformable layer of a flexible elastomer covers the electrodes. The semi-conductive conformable layer limits current flow between electrodes and relaxes charge deposited on the roller surface. Stationary pre-nip and post-nip contacts apply the bias to the imbedded electrodes. The electrodes in the post nip region are biased to VPOST. The electrodes positioned in the pre-nip regions are either grounded or biased to VPRE
