  • Patent number: 9417588
    Abstract: An image forming apparatus has a developing unit, a fixing unit, a receiving unit, a paper setting unit, and a control unit. The fixing unit conveys paper on which a visible image is formed by the developing unit between a heating roller and a pressurizing roller to fix the visible image to the paper. The receiving unit receives a demand for smoothing-out of wrinkles of the paper. The paper setting unit sets paper to be subjected to smoothing-out of wrinkles. When the receiving unit receives the demand for smoothing-out of wrinkles, the control unit performs control so that the developing unit is not operated and the paper to be subjected to smoothing-out of wrinkles set in the paper setting unit is conveyed to the fixing unit.

  • Patent number: 8582184
    Abstract: An image reader and document conveying method shorten times necessary for a discharge process that discharges a document in being conveyed and for an idle feeding process of a document that is left on a paper feed tray. If during double-sided reading, a stop key is operated to issue an instruction to cancel reading, a conveyance controller outputs a path specifying signal to select a single-sided path, and thereby a conveyance route is switched from a double-sided path to the single-sided path. For this reason, the discharge process that discharges a document being conveyed at the time of the reading cancellation to a paper discharge tray, and the idle feeding process that discharges a document left on a paper feed tray to the paper discharge tray are performed with use of the single-sided path that is shorter than the double-sided path, and therefore the times necessary for the discharge and idle feeding processes can be shortened.

    Abstract: A sheet-fed double-sided document scanner is disclosed and includes a first image-capturing assembly, a second image-capturing assembly, a sheet-transporting mechanism, a power receiving interface, and a control circuit. The scanner switches scanning modes according to a power input. The sheet-transporting mechanism transports a document past the first image-capturing assembly and the second image-capturing assembly. The power receiving interface receives power. When a power level of the received power is less than a default threshold level, the control circuit controls the scanner to scan a first side and a second side of the document in a first mode. When the power level of the received power reaches the default threshold level, the control circuit controls the scanner to scan the first side and the second side of the document in a second mode.

  • Patent number: 8237962
    Abstract: A method receives a print job and analyzes the complexity of the print job to generate complexity factors. The method performs raster image processing (RIP) on the print job and records the time taken to perform the raster image processing of each page of the print job. This generates “RIP times.” In addition, the method records the size of each page of the print job to generate “page sizes.” Then the method prints the print job and records the time it took to process the print job. Then the method determines how each of the complexity factors, the RIP times, and the page sizes contributed to the time it took to process the print job. This generates “complexity factor time values.” The method prints a report of the complexity factor time values detailing how each of the complexity factors contributed to the time it took to process the print job.

  • Patent number: 7843601
    Abstract: A method for forming a color image that allows a color image forming device to detect print chromaticity by an actually used print medium and automatically perform an optimal color balance adjustment in consideration of the chromaticity of the print medium. At a first step of the method, it is determined whether a feeder is selected for a subsequent printing operation. If selected, the process proceeds to a second step. If not selected, it is determined that the printing operation is not performed for some time and the process is completed without color balance adjustment. At the second step, a print medium for printing a test pattern is fed from the feeder selected for a subsequent printing operation, which is determined at the first step. A color sensor detects the chromaticity of the test pattern transferred and fused on the print medium, and the color balance is then adjusted.

This reversible sheet feeding path in the module is alternately operable unidirectionally to provide an arcuate, inverting, sheet output path to a sheet output stacking tray which may be located on top of the plural function module.

  • Patent number: 6348962
    Abstract: A novel device for image-shooting both surfaces of documents at a high rate by an electronic device. The device has an upper transport system for allowing plural documents to descend/move by a pre-set number at a time towards the downstream and an image-shooting device for image-shooting the descending/moving document. Image-shooting can be done simultaneously on both sides or side by side, either during free movement or controlled movement by a transporting device.

  • Patent number: 6288768
    Abstract: An image reading device capable of reading images on the both surfaces of a document in order while moving the document at a prescribed speed includes a platen for reading the document moving at the prescribed speed, a reversible transferring device for moving the document at the prescribed speed along the platen, and a circulating passage for turning the document and sending back to the platen after reading the image on the obverse surface of the document. The circulating passage is composed of at least first and second turning paths for inverting a direction in which the document is transferred to turn the document upside down, so that the images on the obverse and reverse surfaces of the document can be continuously read with a compact mechanism and starting to scan from the same end of the document whenever the document is read.

    Abstract: A removable cover for protecting a reticle used in a lithography system is described. The removable cover includes a frame and a membrane supported by the frame. The membrane is transparent to an inspection wavelength such that the reticle can be inspected with the removable cover in place. This removable cover protects the reticle when the removable cover is in place and is removable for lithographic exposure. The removable cover can further include at least one reticle fastener that applies force to the reticle thereby preventing movement of the removable cover relative to the reticle when the removable cover is in place. A plurality of fasteners are used to position and secure the removable cover and reticle. A method of performing lithography and a lithographic system are also described.

  • Patent number: 6198525
    Abstract: Apparatus for contact exposing each side of a substrate to a different image on a mask includes a first-side imaging station for imaging the first side of the substrate, a second-side imaging station for imaging the second side thereof, an intermediate station between the imaging stations for inverting the substrate. In each imaging station, the substrate is moved longitudinally with a transport carriage, from which it is transferred to an imaging carriage to be driven to an imaging point at which illumination through the mask occurs. The imaging carriage moves in both longitudinal and transverse directions, providing for both exposure to a mask covering the substrate and for step-and-repeat exposure of multiple portions of the substrate to a smaller image. Before exposure, the top surface of the substrate is aligned to be parallel to the adjacent mask, fiducial markings in the substrate are aligned with fiducial markings on the mask, and air is evacuated from the area between the mask and the substrate.

  • Patent number: 5854670
    Abstract: An image forming device having multiple direction lens system, a presetting system, a page turner, a movable platform to manipulate both unbound and bound originals, an image monitoring unit, a microcomputer-based control system and an image formation unit, is disclosed that provides the capability of automatic and manual image formation from both unbound and bound originals. The automatic image formation from bound originals is enabled in both Flat Open Mode (original 180.degree. face-up opened) and Angled Open Mode (originals less than 180.degree. face-up opened). Unbound documents can also be face-up loaded on the movable platform for the automatic image formation and will never be jammed. While having bound or unbound originals face-up positioned on the 3D-movable frame, the manual image formation in both single and dual projecting direction also becomes much easier and effective with higher copy quality.
