    摘要: A method for calibrating a printer including a light-emitting diode (LED) printhead for non-uniformity on an image plane. The LED recording elements are arranged in a plurality of arrays. A plurality of characteristics (102, 104, 106, 108, 110) associated with each recording element are measured and from the measured characteristics a plurality of parameters (112, 114, 116, 118, 120) associated with each recording element is determined. Adjustment factors for a plurality of parameters are combined mathematically to determine an adjusted power density (122) for each recording element on the image plane. Correction factors (130) are then assigned to each recording element to correct for the adjusted power density (122). The correction factors (130) are stored in a memory (132) associated with the LED printhead.

    摘要: A uniform layer of charged toner particles is deposited onto a photoconductive layer of an imaging member. The toner particles are imagewise heated to imagewise tack selected ones of the particles to the photoconductive layer. The photoconductive layer is uniformly exposed to actinic radiation to discharge the toner particles while the layer is subjected to a gentle cleaning process which removes the nontacked toner particles.

    摘要: An improvement in the method and apparatus for producing a multi-color electrophotographic image wherein an electrophotographic medium is mounted on a carrier therefor and is translated over a predetermined path so that the medium is first charged, then exposed to a first light-borne image and then toned. Thus, the unexposed portions of the image bearing charged region of the medium are toned, preferably by a liquid toner, to produce a first color visible image. The carrier is then returned to the first position to repeat the foregoing steps to charge the medium and to expose it to a second light-borne image and to tone the second image with a second toning element to produce a second color visible image on the same sheet of medium. One of the images formed is a cyan image. The improvement comprises the steps of: developing the cyan image with a self-fixing, liquid electrographic developer comprising a volatile, electrically insulating liquid carrier and, dispersed in said carrier, (i) toner particles comprising a polymeric binder, cyan pigment and a dispersing agent and (ii) wax particles, and then buffing the surface of the cyan image with a relatively coarse, stiff, and rough fibrous brush member after the cyan developing step and prior to the next charging step to prevent small toner particles present in liquid toner from adhering to the cyan image and thereby contaminating the cyan image and whereby the cyan image does not flake off or smear during the buffing step.

    摘要: A bleachable composition, including an acid photogenerator and a near-infrared radiation-absorbing dye or pigment, is utilized in a method of migration imaging to prevent unwanted absorptions. This composition can be incorporated either in the thermoplastic imaging surface layer of the imaging element, in the marking particles applied to the element, or both. Alternatively, the components of the bleachable composition can be separated with one in the thermoplastic imaging surface layer and the other in the marking particles. After the imaging element is marked and exposed with near-infrared radiation, the bleachable composition causes exposed portions of the imaging element to be bleached. If further bleaching is needed, the element can subsequently be exposed with near-ultraviolet radiation.

    摘要: First and second toner images are created on a primary image member. The first toner image is transferred to an intermediate image member and then transferred back to the primary image member to combine the two images. Preferably, the intermediate image member is a light roller that is inarticulatable and maintained in contact with the primary image member which is preferably an endless belt with sufficient wrap to drive the intermediate image member with low pressure in the contact nip. Cleaning is effected by transferring residual toner back to an empty portion of the primary image member from where it may be cleaned off by a primary image member cleaning station. Intrack registration of the images is maintained by adjusting the time between flashes in creating the two images.

    摘要: A xeroprinting master includes a fixed insulative toner image on an electrophotographic element of the type exhibiting charge injection at an interface between a charge injection electrode and a charge transport layer. In xeroprinting use the master is charged to a polarity opposite that which is injectable. The charge is neutralized by charges injected from the electrode which migrate to the charged surface. Charge retained on the fixed toner image can be toned. The master can be made by positively charging it to a polarity the same as that which is injectable, imagewise exposing it and toning and fixing.

    摘要: A migration imaging system using a laser-addressable thermoplastic imaging member. The imaging member comprises a supporting section and a thermoplastic imaging surface layer. A charged, uniform layer of marking particles is deposited on the imaging surface layer. An imagewise-modulated laser beam transforms selected volumes of the imaging surface layer in an imagewise pattern to a permeable state. Charged marking particles that superpose a transformed volume then migrate into the imaging surface layer so as to be retained. Unaddressed marking particles are cleaned away. The imaging member, or solely the imaging surface layer, may be transferred and bonded to a receiver such as a drum for use as an exposure mask, or to a receiver sheet to provide a hard copy reproduction. The processed imaging member is usable as a master in a xeroprinting system.
