Abstract: A method for printing an image on a substrate by image-wise depositing, toner particles on the substrate, is disclosed, comprising: image-wise depositing dry toner particles on the substrate forming a first band-like portion of the image, conditioning the first band-like portion while keeping the substrate at a temperature equal to or lower than 100° C. and further image-wise depositing toner particles on the substrate so as to form at least one other band-like portion of such image, the at least one other band-like portion of the image being adjacent to the first band-like portion. Preferably the method is used for printing substrates with an area equal to or larger than 0.25 m2.

Abstract: A fusing station (25) of an electrographic apparatus fixes in a single pass a duplex resinous powder color image (8, 18) to a support material in sheet-form (9) as the sheet is moved over a predetermined path (7). The station comprises two heated fixing rollers (1, 11), rotating in contact with each other, driving means to rotate the fixing rollers, pressing means for applying a meshing force between the fixing rollers, heating sources (4, 14) which have substantially identical characteristics. Both fixing rollers comprise a heat conducting core (3, 13) and a resilient covering (2, 12) which by the pressure between both rollers forms a heating nip. A symmetrical fixing operation on both sides of the sheet is provided. Hereto, the fixing rollers have a substantially identical construction, are positioned symmetrically to the path of the sheet and rotate synchronously to the advancement of the sheet.

Abstract: A DEP device is provided that comprises a back electrode (105), a printhead structure (106), an array of printing apertures (107) in the printhead structure (106) through which a particle flow can be electrically modulated by a control electrode (106a), a toner delivery means (101), presenting a cloud (100) of dry toner particles in the vicinity of the apertures (107), characterized in that the toner cloud (100) is formed in the vicinity of the apertures (107) by means of a gas stream. The toner cloud is formed by detaching toner particles from a charged toner conveyer by the gas stream, or by forming a fluidized bed of toner particles.

Abstract: A fusing station of an electrographic apparatus fixes in a single pass a duplex resinous powder color image to a support material as the support material is moved over a predetermined path through the fusing station. The fusing station employs a symmetrical fixing operation on both sides of the support material. The fusing station applies hot air to both sides of the support material in substantially equal flows. The hot air is heated by heating sources with substantially identical operational characteristics such that the flows of hot air are heated to substantially equal temperatures on both sides of the support material.

Abstract: A heat and pressure fusing device (10) for fixing toner images to a receptor support, the device having a fixing (12) and a pressure (13) roller rotating in contact with each other, wherein the fixing roller has a diameter larger than 70 mm.

Abstract: Drum-type imagesetter for producing an image on a flexible sheet of radiation-sensitive material, which comprises retaining bars (62) for retaining a sheet in a substantially cylindrical configuration, and an exposure system (70) for image-wise exposing the curved sheet, the radial position of the sheet retaining bars (62) being controlled by adjustment screws (49, 50) allowing different drum diameters to be set.

Abstract: Rotating drum (10) imagesetter for producing an image on a flexible sheet of radiation-sensitive material, wherein a sheet (20) is held on the inside surface of the drum (14), and the exposure means (25) his located inside the drum.

Abstract: The present invention provides an assembly of a first panel formed with at least one insertion notch extending inwardly from at least one panel edge and a second panel carrying at least one projecting tab extending outwardly of at least one of its edge and fitting in one of the notches. The tab has on at least one of its sides a shoulder defining an edge which is located along the projecting length of the tab at a position intermediate the free edge of the tab and its base, which usually coincides with the edge of the panel from which it projects. The shoulder edge is in abutting contact with a region of the first panel adjacent the insertion notch in the first panel in which the tab fits and functions to maintain the associated edge of the second panel out of contact with the first panel so that the relative positions of the panels is determined by such abutting contact and is independent of other factors, such as the precise linearity of the panel edge.

Abstract: The present invention provides an assembly of a first panel formed with at least one insertion slot and a second panel carrying at least one projecting tab extending outwardly of at least one of its edges and fitting in the slot. The tab has on at least one of its sides a shoulder defining an edge which is located along the projecting length of the tab at a position intermediate the free edge of the tab and its base. The shoulder edge is in abutting contact with a region of the first panel adjacent one of the insertion slot and thus maintains the associated edge of the second panel out of contact with the first panel so that the relative positions of the panels is determined by such abutting contact. The first and second panels can be positively secured together by means of an interconnection element, preferably in the form of an integral flange bent up from one of the panels, which is attached to one or both other panel by screws, bolts and nuts or similar attachment devices.
