This invention relates to a pyramid polygon scanner without cylinder optics wherein the effects of jitter are reduced by the use of a start of scan detector situated at a predetermined angle from the normal (vertical) position. The start of scan detector is rotated about an axis through the nominal scan line. Thus, if tilt (not the draft angle) is present in the rotating polygon system and jitter is generated, the rotation angle of the split detector moves the jitter to the beginning and end of ...

A method and apparatus using ion projection to form a tri-level latent image on a charge retentive surface. The tri-level image which comprises two image areas and a background area is utilized for highlight imaging.

A method of assembling parts in which, before actual assembly of the parts, the forces associated with a good assembly of parts and the forces associated with a faulty assembly of parts are identified to train a pattern of recognition signature analysis system. During assembly, the forces required to actually assemble the parts are measured and a determination is made by the system as to whether these forces are associated with a good assembly or a faulty assembly to determine if the assembled p...

A photoconductive imaging member comprised of a supporting substrate, an inorganic photogenerating layer, or a photogenerating layer comprised of metal free phthalocyanines, metal phthalocyanines, vanadyl phthalocyanines, squaraines, perylenes, or dibromoanthrone; and a charge transport layer comprised of N,N-bis(biarylyl)aniline compounds of Formula (I) or tris(biarylyl)amine compounds of Formula (II), wherein R, R', R" are independently selected from the group consisting of hydrogen, halogen, ...

The present invention relates to a development apparatus including structure for the dynamic toner metering and charging of nonmagnetic single component toner. To this end there is provided a flexible, rotating rod having an electrical bias applied thereto. The rod is captured or supported by a distributed bearing attached to a compliant blade. A toner cleaning blade held against the rod serves as a toner seal. The flexible rod is supported in a self-spaced relationship to a rigid donor roll whi...

An ink jet printhead fabrication process wherein a plurality of printheads are produced from two mated substrates by two dicing operations. One dicing operation produces the nozzle face for each of a plurality of printheads and optionally produces the nozzles. This dicing blade, together with specific operating parameters, prevent the nozzles from chipping and the nozzle faces from scratches and abrasions. A second dicing operation with a standard dicing blade severs the mated substrates into se...

A magnetic brush developer apparatus including a plurality of developer housings each including a plurality of magnetic brush rolls associated therewith. Conductive magnetic brush (CMB) developer is provided in each of the developer housings. The CMB developer is used to develop electronically formed images. The physical properties such as conductivity, toner concentration and toner charge level of the CMB developers are such that density fine lines are satisfactorily developed notwithstanding t...

An encapsulated toner composition with a melting temperature of from about 65.degree. C. to about 140.degree. C. comprised of a core containing a polymer selected from the group consisting of polyethylene succinate, polyhalogenated olefins, poly(alpha-alkylstyrenes), rosin modified maleic resins, aliphatic hydrocarbon resins, poly(.epsilon.-caprolactones), and mixtures thereof; and pigment particles, where the core is encapsulated in a shell prepared by interfacial polymerization reactions.

An image sensor array and method of fabrication which facilitates replacement of a defective one in a series of arrays butted together to form a longer scanning array in which a (110) silicon wafer having a row of photosites has separation lines etched thereon by orientation dependent etching along the (111) planes, with the separation lines for the opposite ends of the array each consisting of first and second partial boundary lines longitudinally offset from one another connected by a third bo...

Highlight color imaging method and apparatus including structure for forming a single polarity charge pattern having at least three different voltage levels on a charge retentive surface wherein two of the voltage levels correspond to two image areas and the third voltage level corresponds to a background area. Interaction between developer materials contained in a developer housing and an already developed image in one of the two image areas is minimized by the use of a scorotron to neutralize ...
