    摘要: An inkjet printer for printing on a continuous web of recording media includes a receiver to receive a beam of collimated light transmitted across the surface of a continuous web of recording media supported by a roller. The intensity of the transmitted beam received by the receiver can be used to determine the presence of a defect in the continuous web or in the roller. A controller is configured to reduce the speed of or stop movement of the web through the printer and to retract one or more printheads from a printing location to prevent the defect from damaging the printhead(s).

    摘要: A method and apparatus for preventing ghosting defect, which appears as a lightened ghost image of a previously developed image in a halftone or solid. The defect is due to the different characteristics of the toner that has been reloaded into the recently detoned areas of the donor roll from that toner which has remained on the donor and passed through the reload nip a number of times. A developer unit for developing a latent image recorded on an image receiving member with marking particles, to form a developed image, comprising: means for moving the surface of the image receiving member at a predetermined process speed. A donor member is spaced from the image receiving member and adapted to transport marking particles to a development zone adjacent the image receiving member. A housing is provided defining a chamber storing a supply of developer material comprising toner. The donor member is biased to a first predefined potential. A magnetic brush loads a toner layer onto a region of said donor member; and a charging device charges said toner layer loaded on the region of said donor member to a second predefine potential and wherein said first potential substantially equal said second potential.

    摘要: In a highlight color imaging method and apparatus, the charging level of a scorotron used for charge neutralizing an already developed image is controlled by using the bias voltage of a second developer housing as a reference voltage for the the grid of the scorotron. The bias voltage applied to the scorotron is offset a predetermined amount from the bias voltage of the second developer housing.
