Abstract: An apparatus in which release material is applied to a heated fuser member. A back up member is in communication with the fuser member and a sheet of support material having particles thereon passes therebetween. The particles on the sheet of support material contact the fuser member. The apparatus reciprocates a bar of release material into and out of contact with the fuser member.The foregoing abstract is neither intended to define the invention disclosed in the specification, nor is it intended to be limiting as to the scope of the invention in any way.

Abstract: An apparatus in which the manual placement of successive original documents onto the platen of a reproducing machine is facilitated. A plurality of original documents are located on the platen with the lowermost document being positioned thereon for reproduction. After being reproduced, the lowermost document is removed from the platen while the uppermost document is retained thereon enabling it to be subsequently reproduced.

Abstract: An apparatus in which a quantity of particles is stored and gradually dispensed to a mix thereof. Bridging and caking of the particles is prevented by forming grooves and inducing vibrations in the developer mix at predetermined intervals of time.

Abstract: An apparatus for developing an electrostatic latent image. The apparatus is moved from an inoperative position spaced from the latent image to a position in operative communication therewith. After the latent image is developed, the apparatus is moved to the inoperative position thereof.

Abstract: A photoreceptor cleaning composition is provided which includes a solvent blend that is capable of dissolving toner polymers and paper tars. This composition cleans effectively and efficiently without damage to the photoreceptor and without leaving residue. This solvent employs a blend of halogenated hydrocarbons having specific physical and chemical properties. These compositions are superior to known cleaners by virtue of their minimizing potential for fire explosion and hazard resulting from toxicity and volatility.

Abstract: An optical system in which a screened light pattern and a light image of an original document are projected onto a common region of a light receiving member forming a modulated light image thereon. Collimated light rays are employed in the formation of the screened light pattern.

Abstract: Adjustable guides for a sheet stack are frictionally secured to the stack support by bristle pads provided on each adjustable guide and on the stack support. Each pad has bristles inclined at an acute angle relative to the surface of the pad. Interleafing of the bristles on the guides and the stack support provides adjustable, frictional securement of the guides to the stack support.

Abstract: A device in which a developability regulating apparatus employed in a multi-color electrophotographic printing machine is maintained substantially free from contaminating particles. This is achieved in the present invention by directing a substantially laminar fluid flow over the light source and photosensor used in the developability apparatus.

Abstract: An apparatus in which an original document is housed. The support on which the original document is positioned becomes selectively opaque so as to mask portions of the original document disposed thereon.

Abstract: An apparatus in which the quantity of release material metered to a heated fuser member is regulated. The apparatus includes a blade positioned in contact with the fuser member to remove excessive release material therefrom.

Abstract: An apparatus in which one component of at least a two component mix deposited on a support surface is transferred to a sheet of support material. Initially, the attractive force between the support surface and mix is reduced, preconditioning the mix. Thereafter, the other component of the pre-conditioned mix is removed from the support surface. The remaining one component of the pre-conditioned mix is then transferred from the support surface to the sheet of support material.

Abstract: Synchronizing apparatus is disclosed in accordance with the teachings of the present invention wherein the operation of a first device is regulated in accordance with the operation of a second device. The phase relationship between signals representing the operation of the first and second devices, respectively, is determined by comparison means which produces a pulse width modulated signal indicative of said phase relationship. Control signal generating means responds to the pulse width modulated signal to generate an analog signal having an amplitude established by said phase relationship. Feedback means, including variable frequency generating means, is controlled by the analog signal to modify the operation of the first device whereby said first device is urged into a synchronous relationship with said second device and the signals representative of the operation of said first and second devices admit of a desired phase relationship.

Abstract: A process for the preparation of substantially hexagonal crystals of metal-free alpha phthalocyanine, said crystals ranging in size from about 1 micron to about 75 microns is disclosed. Photoelectrophoretic and manifold processes employing said crystals are also disclosed.

Abstract: This invention relates generally to a method of color reproduction and the apparatus employed therefor. More particularly, the invention concerns a method and apparatus employed in masking an original document so as to create color highlights or a color copy from a black and white or color original.
