  • Patent number: 11429048
    Abstract: A transmission unit transmits driving force to be supplied from a motor to a roller pair. A switching unit acts on the transmission unit to switch a rotation direction of the roller pair by the driving force between a normal rotation and a reverse rotation. A control unit controls a rotation speed of the motor to convey the sheet at a second conveyance speed in a part of a first time period. The second conveyance speed is lower than a first conveyance speed. The first conveyance speed is a conveyance speed when the sheet is conveyed in the image forming unit. In the first time period the sheet having the image formed on the first surface is conveyed in a first direction. In a second time period the sheet is conveyed in a second direction.

    Abstract: In a printing system capable of supplying a sheet of a job having undergone print processing by the printing unit of a printing apparatus to a post-processing unit capable of executing at least a specific type of post-processing among a plurality of types of post-processes, when the target job requires the specific type of post-processing, the printing apparatus is inhibited from executing print processing of the job without explicitly determining a sheet necessary for the print processing of the job by a user using a user interface unit. When the target job does not require the specific type of post-processing, the printing apparatus is permitted to execute print processing of the job without explicitly determining a sheet necessary for the print processing of the job by the user using the user interface unit.

    Abstract: A modified polymer body 1 has a polymer body 2 composed of a polymer material containing a carbon-carbon double bond and first binding parts 3 and second binding parts 4 bound to the surface of the polymer body 2. The first binding parts 3 are such that an organic group 6 having a functional group is bound via an isocyanuric acid skeleton 5 to the surface of the polymer body 2. The second binding parts 4 are such that an organic group 7 having a functional group is directly bound to the surface of the polymer body 2 without interposing an isocyanuric acid skeleton 5.

  • Patent number: 8774679
    Abstract: An electrographic printing system for forming a tactile printed image on a receiver medium, comprising an image processing path, one or more printing modules and a fixing subsystem. The image processing path provides a sequence of image patterns including a plurality of annular shapes having associated inner and outer sizes, the inner and outer sizes of the annular shapes varying in a monotonic sequence. The printing modules are controlled to form a sequence of toner particle images corresponding to the sequence of image patterns, and to sequentially transfer the sequence of toner particle images in register onto the receiver medium such that the annular shapes in the toner particle images overlap to form a tactile image feature having a hollow core. The fixing subsystem is used to permanently attach the transferred toner particle images to the receiver medium.

  • Patent number: 8711380
    Abstract: The disclosure proposes the automatic use of the job or image content information of a print job. This information is used to automatically adjust the general printing procedure for a print engine. The job's image content information is analyzed in the context of the constraints of the print engine to determine an improved printing procedure, which may include cycle-up operation, process control cycles, or maintenance cycles for that particular print job.

  • Patent number: 8675254
    Abstract: An image processing device includes: a storage part configured to store a correlation between a pre-deformation color and a post-deformation color that reflects a color variation accompanying a deformation of a medium, with respect to a degree of deformation of the medium; an acquisition part configured to acquire degree-of-deformation information and color information for each region of a deformed object; and a determination part configured to determine a color of the image based on the degree-of-deformation information, the color information, and the correlation, so that the post-deformation color of each region of the deformed object approximates the color information.
