摘要： A document reproduction system is disclosed which employs an imaging array assembly positioned to transmit reflected images from a document in an object plane onto an imaging plane. The imaging assembly includes a 1X lens array and at least one reduction/enlargement lens array. The overall dimensions of the total imaging area of the reproduction system are reduced from conventional fixed lens or fixed document system by providing means for moving the document, imaging assembly and imaging plane in certain prescribed relationships. These means include a pulley/cable/clutch arrangement which enables changes in velocity relationships which are required for a unity magnification mode of operation as well as those for a reduction or enlargement modes of operation.

摘要： A raster output scanner assembly having a first laser source for producing first and second laser beams, and a second laser source for producing third a fourth laser beams. The first and second laser beams are directed to a first rotating, multifaceted polygon while the third and fourth laser beams are directed to a second rotating, multifaceted polygon. The first polygon reflects the first and second laser beams onto a moving photoreceptor while the second polygon reflects the third and fourth laser beams onto the photoreceptor. The spots produced by the various laser beams are interlaced such that the scan line produced by the third laser beam is between the scan lines produced by the first and second laser beams, while the scan line produced by the fourth laser beam is adjacent the scan line produced by the second laser beam.

摘要： A printing machine in which two electrostatic latent images are recorded on a photoconductive member. One of the latent images is a charged area latent image with the other image being a discharged area latent image. A magnetic developer unit develops the charged area latent image with black toner particles. A non-magnetic developer unit develops the discharged area latent image with toner particles of a color other than black. The toner particles from both latent images are transferred substantially simultaneously to a sheet and fused thereto forming a color high lighted document.

摘要： A multiple diode laser array used in a ROS scanning system is modified to reduce the effects of undesirable spatial exposure variation at the surface of certain type of layered, semi-transparent photoreceptors. The spatial absorption variation is later manifested as a "plywooding" pattern formed on output prints derived from the exposed photoreceptor. The laser array is modified to form a merged scanning beam at the photoreceptor surface of two or more diode outputs, each output operating at a different wavelength than the other. In one embodiment, a plurality of diodes, each at a different wavelength, are sequentially addressed, and an image of each diode is scanned across the photoreceptor which results in an exposure distribution that would be similar to that formed by an incoherent beam.

摘要： The present invention is directed to optical imaging systems which utilize linear lens arrays and particularly gradient index lens arrays as the means for projecting light images onto a photosensitive image member. Exposure modulation at the image plane is reduced by oscillating the lens array during an exposure interval, the oscillating period and excursion distance being dependent upon the type of imaging environment the lens is used in. For document copying applications, the requirement for a two-row array to provide minimum exposure modulation is reduced so that a one-row lens array is enabled. For printer and RIS scanning functions, oscillation of a two-row array enables improved system efficiency and hence greater image irradiance and exposure.

摘要： An imaging system is disclosed which incorporates a gradient index lens array to transmit focused light onto an image medium with increased Depth of Focus (DOF) and no loss of radiometric efficiency. The lens array is first constructed so that its exit pupil is generally symmetrical. This first step increases the radiometric efficiency of the lens array relative to prior art lens arrays. In a second step, the DOF is increased by reducing a quantity n.sub.o .sqroot.AR which is associated with the lens, n.sub.o being the axial refractive index of the fibers comprising the lens array, .sqroot.A being the gradient index constant of the material comprising the lens array and R being the radius of the individual optical rods, As this quantity is reduced, the DOF increases consistent with a trade off of reduced radiometric efficiency. Since the efficiency was initially increased from some optimum value, the DOF can be increased until the desired radiometric efficiency level is reached.
