  • Patent number: 8867057
    Abstract: This invention relates to a printing system configured to output printing media having undergone print processing by a print apparatus to a plurality of destinations including a specific destination which has a structure allowing an operator to take out the printing media. In the system, output of printing media to the specific destination is restricted while the operator takes out the printing medium outputted to the specific destination, and in case that the number of printing media necessary for a job processed by the print apparatus is smaller than a predetermined number, the system is controlled not to output to the specific destination a printed material formed from printing media smaller in number than the predetermined number. This invention can achieve efficient printing by controlling not to stop the print operation of the system as much as possible.

  • Patent number: 7556253
    Abstract: An auto document feeder cooperated with an image processing machine defines a feeding path and has a base, a frame and a sensor device. The base has a background under the feeding path. The frame is mounted on the base. The sensor couples with the frame and has a sensor arm. The sensor arm has an optical sensor located in the feeding path and faced to the background of the base. The sensor device recognizes a sheet is present in the feeding path or not by that the optical sensor recognizes the energy of the light reflected from the background and the sheet. The sensor device also recognizes characteristic of the sheet by that the optical sensor recognizes the energy of the light reflected from the sheet. Therefore, the image processing machine executes different processes for the sheet according to the characteristic of the sheet.

  • Publication number: 20090066005
    Abstract: The present application is directed to methods of determining a width of a media sheet moving along a media path of an image forming apparatus. The methods may include moving the media sheet along the media path and past a media width sensor that includes a shaft with a first upstream paddle positioned away from a reference location of the media path and a second downstream paddle positioned in closer proximity to the reference location. The first paddle is positioned a first distance from the first sensor, and the second paddle is positioned a second distance from the first sensor. As the media sheet moves along the media path, a first signal may be received when the media sheet contacts the first sensor, and a second signal when the media sheet is at the media width sensor. The distance the media sheet travels between contacting the first sensor and being at the second sensor may be determined.

  • Publication number: 20080246207
    Abstract: A simplified sheet sensor and registration gate for feeding print media sheets from a stack loaded by a user into a receptacle on a photocopier. The gate is pivoted on the mechanism and has a flag attached; and, upon user loading of sheets into the receptacle, the gate is pivoted against a locking arm and the flag is moved to actuate an optic sensor that sheets have been loaded. The locking arm is pivoted on the nudger roll arm and unlocks the gate when the nudger roll is moved down to contact the top sheet in the stack. When the sheet receptacle is unloaded, the gate is pivoted by gravity to the downward position and the locking arm pivots by gravity to reset. If the nudger is raised for sheet jam clearance, the locking arm is pivoted to clear the gate, allowing the gate to drop. The locking resets by gravity.

  • Patent number: 7391043
    Abstract: Various edge detection arrangements are disclosed, including an edge detection method and arrangement that utilizes outputs of commonly illuminated reference and edge sensors as the inputs for a comparator. The reference sensor is configured to have a wide field of view and the edge sensor is configured to have a narrow, high gain, field of view. Therefore, the reference sensor has a broad signal response to an edge passage and the edge sensor a steep and narrow signal response. When the two signals are biased to cross each other, the comparator output changes state, indicating passage of an edge. Because the reference sensor provides a base signal level directly related to the real time illumination level that the edge sensor also receives, the reference sensor provides a switch point along the transition ramp of the edge sensor that integrates a majority of the random error sources.

    Abstract: A sheet supply device is formed of a sheet supply stacker, a supply path for guiding a sheet stacked on the sheet supply stacker, a sheet process portion situated in the supply path, and a switch-back path positioned on a downstream side of the sheet process portion. The switch-back path guides the sheet which has passed through the sheet process portion again to the supply path by switching back the sheet. The sheet having passed through the sheet process portion is ejected onto a sheet ejecting stacker. After a first supply of the sheet to the sheet process portion is made, the sheet is reversed by the switch-back path to make a second supply to the sheet process portion; the sheet having been subjected to the second supply is again reversed by the switch-back path to make a third supply to the sheet process portion, and then ejected onto the sheet ejecting stacker. A first supply of a next sheet to the sheet process portion is made between the second and third supplies of the preceding sheet.

Of the documents re-set on the document tray, the documents from which image information have been copied are discharged onto a discharge tray, without executing a copying operation. In other words, a copying operation is executed only for the documents from which image information have not been copied.

  • Patent number: 6220590
    Abstract: The invention pertains to a hopper loader apparatus for separating and forming an overlapping shingled stream of individual signatures of sheet materials from a vertically aligned, parallelepiped shaped stack of such signatures for subsequent handling operations. The hopper loader has a slippage resistant belt which engages a bottom edge of each signature and assists in preventing the signatures from slipping by keeping them upstanding. Preferably the slippage resistant belt has an array of projections extending upwardly from a belt surface which secures the signatures in place. This produces a smooth, regular, even signature stream. Individual signatures flow reliably, one-by-one off of the downward conveyor to another conveyor.
