    Abstract: An image forming apparatus with a double-face printing function is provided. The image forming apparatus includes an image forming unit, a sheet feeding path including a regular feeding path and a return-feeding path and capable of accommodating a plurality of recording sheets, a sheet-ejection controller to eject the recording sheet out of the sheet feeding path through a sheet outlet. The sheet-ejection controller controls a recording sheet closer to the sheet outlet in the direction of sheet-conveyance along the sheet feeding path to be ejected prior to a recording sheet further from the sheet outlet when cancellation of the print job is entered during a double-face printing operation, in which the images are formed on one side of N pieces of recording sheets continuously and the other side of M pieces of recording sheets thereafter, whilst M is smaller than or equal to N.

    Abstract: A sheet-feeding type scanning apparatus and an automatic sheet feeding method are provided. The sheet-feeding type scanning apparatus includes a scanning module, a first sheet input tray, a first sheet pick-up roller assembly, a sheet ejecting tray, a sheet transfer channel, a plurality of transfer roller assemblies, a sheet ejecting roller assembly, a sheet-feeding sensor and a clutch module. Once a first sheet article of multiple sheet articles placed on the first sheet input tray are fed into the internal portion of the sheet-feeding type scanning apparatus to trigger the sheet-feeding sensor, the clutch module is disabled. At this moment, a second sheet article placed on the first sheet input tray fails to be fed by the first sheet pick-up roller assembly. Therefore, the double feeding problem is solved.

  • Patent number: 7828279
    Abstract: A method of scanning documents obtains the document that is to be scanned from an input tray, transports the document at a transport velocity past a scanner to obtain image data therefrom, and stacks each scanned document aligned with trailing-edge registration in a sloped output tray, in the order of scanning, by a sequence that detects the trailing edge of the scanned document, feeds the leading edge of the scanned document from an exit nip in a forward direction and above the sloped output tray at a transport velocity, then changes the speed at the exit nip to an exit velocity, different from the transport velocity, according to the timing of the trailing edge detection. The trailing edge of the scanned document is ejected at the exit velocity. The exit nip speed is restored to the transport velocity for feeding the leading edge of a subsequent document.
