  • Patent number: 10769507
    Abstract: An image forming apparatus includes a conveyor, a sensor, and control circuitry. The conveyor is configured to convey a sheet. The sensor is configured to detect the sheet conveyed by the conveyor. The control circuitry is configured to cause the conveyor to eject the sheet without stopping conveyance of the sheet and prohibit recovery printing when a size of the sheet determined based on detection of the sheet by the sensor is different from a setting size in a first operation mode. The control circuitry is configured to cause the conveyor to stop conveyance of the sheet and allow recovery printing when the size of the sheet is different from the setting size in a second operation mode in which a number of times of printing is larger than a number of times of printing in the first operation mode.

  • Patent number: 10654240
    Abstract: A sheet processing device has a binding unit that applies water to a crimping range of sheets and then crimps the sheets. The sheet processing device includes a processing tray on which sheets are placed, a pair of pressure teeth (pressure teeth and receiving teeth) that crimps the sheets placed on the processing tray at a crimping position with the sheets interposed therebetween, and a water application member (cylinder and piston) that applies water to the crimping position before crimping by the pressure teeth. When the number of sheets placed on the processing tray is equal to or less than a predetermined number, the sheets are crimped by the pressure teeth without water application; while when the number of sheets placed on the processing tray exceeds the predetermined number, the sheets are crimped by the pressure teeth after water application.

  • Patent number: 10616424
    Abstract: An image forming apparatus includes a main body and a post-processing device. The main body includes an operation panel and a first controller that switches an action mode to a first action mode or a second action mode. The post-processing device includes an operation receiving section and a second controller. The operation receiving section receives an operation by a user and outputs an operation signal. The operation receiving section is in an unreachable position for the user when operating the operation panel. The first controller switches the action mode upon determining that an operation indicated by the operation signal received through the second controller matches a predetermined operation. The second controller controls action of the post-processing device independent of control by the first controller in the second action mode.

    Abstract: Provided is a document reading apparatus capable of suppressing a shock that may occur when a trailing edge of a tabbed sheet passes through a roller pair. In an image reading section, when a document to be read is the tabbed sheet, a timing to start separation of the roller pair in response to detection of a trailing edge of the document is delayed by a time period corresponding to a tab length with respect to the timing to start separation when a document other than the tabbed sheet is conveyed. Thus, it is possible to prevent the shock when the trailing edge of the tabbed sheet passes through the roller pair, and to thereby suppress image reading failure due to the shock.

  • Patent number: 8838004
    Abstract: A sheet of paper is set on a paper-supplying portion of a back surface gloss processing apparatus while its top surface is faced upward. A gloss level sensor measures a gloss level of a back surface of the sheet of paper. Data of this measurement is compared with a previously set threshold value. When this measurement result does not exceed the threshold value, it is determined that the gloss processing has not been performed on the back surface thereof. It is then determined whether or not the presently set operation mode is a top surface gloss processing mode. When determining that the present operation mode is not the top surface gloss processing mode, the operation mode is automatically changed from a presently set back surface gloss processing mode to the top surface gloss processing mode.

  • Patent number: 8831503
    Abstract: An apparatus includes a sheet path, an creasing member positioned on a first side of the sheet path, and a base positioned on a second side of the sheet path opposite the creasing member. The base is positioned relative to the creasing member so that a sheet of print media passes along a processing plane between the creasing member and the base when traveling in a processing direction along the media path. The processing plane is parallel to flat sides of the sheet of print media as the sheet of print media passes between the creasing member and the base. The base comprises a surface positioned parallel to the processing plane. The surface of the base has a recess having a shape corresponding to the creasing member. The surface of the base rotates in the processing plane.

  • Patent number: 8814156
    Abstract: A sheet processing apparatus includes a feed-in path through which a sheet is fed, a first transport path through which a sheet fed from the feed-in path is transported, and a second transport path through which a sheet fed from the feed-in path is transported. The sheet processing apparatus also includes the following elements. A first processor sequentially stacks sheets output from the first transport path and performs first processing on a bundle of stacked sheets. A second processor sequentially stacks sheets output from the second transport path and performs second processing, which is different from the first processing, on a bundle of stacked sheets. A common retention path causes a sheet fed through the feed-in path to temporarily remain on the common retention path and causes the sheet temporarily remaining on the common retention path to be output to one of the first and second transport paths.

  • Patent number: 8797578
    Abstract: A printing control apparatus controls an order of processing executed by a printing apparatus for print jobs included in a first print job group and print jobs included in a second print job group. A detection unit detects a first and second print job included in the first print job group, wherein the second print job has common paper information with the first print job. A control unit arranges processing orders of the detected first and second print jobs to be successive to each other, and arranges a processing order, within the second print job group, of a third print job, which is included in the second print job group and is grouped by a predetermined category together with the first print job, to be equivalent to the processing order of the first print job within the first print job group.
