摘要： An apparatus in which contaminants are on-the-fly removed from an electrode wire positioned between a donor roller and a photoconductive surface. A magnetic roller is adapted to transport developer material to the donor roller. The electrode wire is electrostatically biased with respect to the donor roller to remove contaminants therefrom. The electrostatic wire bias polarity corresponds with the contaminant charge polarity to repel the contaminants from the wire.

摘要： A scavengeless/non-interactive development system using wire electrodes in a development nip between a donor member and a charge retentive surface. The wire electrodes are electrically biased for causing toner particles to form powder clouds in the development nip. Uniform powder clouds are ensured by effecting rubbing contact between the toner particles on a donor roll and a conductive surface.

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.

摘要： A solid area process control for scavengeless development using a transport roll-to-donor roll DC bias as a control parameter in an electrophotographic printing machine is disclosed. The process develops a latent image of a solid area toner patch on a photoconductive belt. Once the patch is developed, the patch is measured with an infrared reflectance type sensor. The measured development mass is compared to a target value stored in the machine memory. A test of the comparison is performed by the process. If the result of the test is less than the target value, the transport roll-to-donor roll bias is increased and the process ends. If the result is more than the target value, the transport roll-to-donor roll bias is decreased and the process ends, otherwise the process stops because the measured development is acceptable. The process is run at predetermined intervals to maintain constant output from the electrophotographic printing machine.

摘要： A multi-color electrophotographic printing machine in which the tangential velocity of the photoconductive drum in the transfer zone is greater than the tangential velocity of the transfer drum having the sheet receiving the transferred images thereon. A buckle is formed in the sheet after the transfer zone, resulting in the sheet being tacked to the developed image on the photoconductive member and moving at the same tangential velocity as the developed image. This is achieved by a transfer sheet having one end secured fixedly over an aperture in the transfer drum. The other end of the transfer sheet is resiliently secured to the transfer drum. The sheet of support material receiving the transferred images is secured at the leading edge to the transfer sheet. In this way, the transfer sheet and the sheet of support material may be induced to form a buckle after the transfer zone enabling the sheet of support material and the developed image to move at the same tangential velocity. By moving at the same tangential velocity, the image smear is eliminated during transfer.
摘要翻译：一种多色电子照相印刷机，其中转印区中的感光鼓的切向速度大于具有接收转印图像的纸张的转印鼓的切向速度。在转印区域之后，在片材中形成带扣，导致片材被粘贴到感光体上的显影图像并以与显影图像相同的切向速度移动。这通过一个转移片实现，转印片的一端固定地固定在转印鼓的孔上。转印纸的另一端弹性地固定到转印鼓上。接收转印图像的支撑材料片在前缘固定在转印片上。以这种方式，可以在转印区域之后诱导转印纸和支撑材料片形成带扣，使得支撑材料片和显影图像以相同的切向速度移动。通过以相同的切向速度移动，在传输过程中消除了图像污迹。

摘要： A printing apparatus or printing system that uses multiple print engines to form an image on a substrate. The printing apparatus or printing system may be a surface printing system or a reverse printing system. Each of the multiple print engines has at least one color station. The color stations are arranged in the print engines and between the multiple print engines based on whether the printing system is a surface printing system or a reverse printing system to control the order in which colorant is formed on a substrate. Multiple print engines allow for, among other things, a greater color gamut and therefore assists in expansion of the standard color gamut.

摘要： A method and apparatus to meter ink for electrographic printing is disclosed. An ink loading mechanism having an anilox roller fills ink from an ink supply into cells in the anilox roller having a plurality of valleys and lands that form the cells. The ink loading mechanism causes the valleys to be full or nearly full with the ink. The anilox roller rotates in a first direction. In one embodiment, a soft blade positioned slightly below surface of the lands removes ink from the cells and causes the valleys to be partially filled as the anilox roller rotates. A hard blade positioned at the surface of the lands to clean residue of ink on the surface of the lands as the anilox roller rotates. In another embodiment, a blanket roller rotationally engaged with the anilox roller pulls ink out of the cells and causes the valleys to be partially filled. The blanket roller rotates in a second direction. A first cleaning blade cleans tops of the lands of the cells.
