摘要： A printing system is provided for color job matching of the output from a plurality of image marking engines. The system includes a first test image printed by a first image marking engine on a media document. The first test image having a data glyph and a plurality of reference patches. The system further includes a second test image printed by a second image marking engine on the media document. The second test image having a data glyph and a plurality of reference patches. The first and second test images are printed on the same side of the media document. A scanner is provided for scanning the media document. The scanned first and second test images provide calibration data for matching color correction tables of the first image marking engine and the second image marking engine, wherein the data glyph and the reference patches of the scanned image data are compared with retrieved color correction tables for generating compensation values based on a difference between the scanned image set-up data and the color correction tables for at least a first subsequent image document on the first image marking engine or the second image marking engine.

摘要： A developer unit for an electrophotographic printer includes a housing defining a chamber for retaining developer material. An auger is rotatable within the chamber for the conveying of developer material within the chamber. The auger and a second rotatable member are adapted to receive rotational drive from a single source of rotational motion. A clutch is responsive to a torque above a predetermined level associated with the auger. A selectably openable outlet port is adapted to permit escape of developer material from the chamber. A linkage is operatively disposed between the clutch and the openable outlet port. A torque above a predetermined level associated with the auger causes the clutch to move the linkage, causing the mechanical linkage to open the outlet port.

摘要： A bead pickoff device for removal of carrier beads adhering to a charge retentive surface subsequent to development of an electrostatic latent image with a developer mix including toner and carrier beads. A stationary magnet member supported within a rotating non-magnetic shell includes a permanent magnet supported in a ferromagnetic strip is provided with first and second sides disposed at an angle in the range of 70.degree. to 110.degree. with respect to each other. The first long side is supported with angled surface free end adjacent the charge retentive surface. The stationary magnet is seated on the second side, spaced from the first. The magnetic field is concentrated in the space between the magnet and the first side to provide an increased bead pickoff force at the charge retentive surface, while the field is attenuated to reduce the force of attraction on the beads as they move away from the charge retentive surface.
