    摘要： Optimization of transfer settings for a given paper and environmental condition is achieved by running a series of prints with varying settings of a transfer parameter such as voltage or current. The mass remaining on the intermediate belt after transfer is monitored for each of the prints. This may be achieved using the same sensor used to monitor and control the developed mass on the intermediate transfer member, such as a transfer belt. A suitable sensor is an Extended Toner Area Coverage (ETAC) mass sensor. Because the control is based on actual conditions for a given paper and environment, it can ensure optimum copy quality over a wide range of papers and conditions, while enabling the minimum target mass per unit area to assure the proper density.

    摘要： A control system for use with a development process including at least one magnetic roll with a settable speed is provided. The controller is directly or indirectly responsive to a reload feedback signal, which signal is generated in response to changes in output reload performance of the development process. In the case of direct responsiveness, the controller uses one or more reload feedback signals to facilitate magnetic roll speed setting. In the case of indirect responsiveness, the controller uses a reload sensitivity signal, which reload sensitivity signal varies as a function of input digital image content and output reload performance feedback, to facilitate magnetic roll speed setting.

    摘要： An apparatus for developing a latent image recorded on an imaging surface, including: a housing defining a reservoir storing a supply of developer material wherein the developer material having predefined triboelectric charge about 20 to 30 microCoulombs/gram. A donor member is mounted partially in the housing and spaced from the imaging surface, for transporting toner on an outer surface of the donor member to a region opposed from the imaging surface. An electrode member is disposed in between the donor member and the imaging surface. A system is provided for loading a region of the doner member with developer material. A charging device ion charges the toner loaded on the region of the donor member to a predefined charge level. A power supply electrically biases the electrode member positioned in close proximity to the imaging member to detach toner from the region of the donor member as to form a toner cloud for developing the latent image.

    摘要： A color electrophotographic printing machine in which latent images having a resolution of at least 1.44 million pixels per square inch are recorded on a photoconductive member. Different color toner powder images are developed in superimposed registration with one another to form a composite multicolor image. The composite multicolor image is transferred from the photoconductive member to a receiving member. Toner particles which have a selected pigmentation and small volume average diameters are used to minimize curl of the receiving member.
