  • Patent number: 9128655
    Abstract: A reception unit receives, in a case where an error has occurred in an image forming apparatus during execution of a designated job, error information indicating that the error has occurred. An acquisition unit acquires information indicating that it is designated to skip the error and to execute the job in the image forming apparatus. A determination unit determines, in a case where the acquisition unit acquires the information, whether or not to continue to display the error information depending on a type of the error. A control unit continues, in a case where the determination unit determines that the error information is continued to be displayed, to display the error information, and ceases, in a case where the determination unit determines that the error information is not continued to be displayed, to display the error information.

  • Patent number: 8045225
    Abstract: An image forming apparatus includes a data recording unit to store a misregistration amount of a scanning line from an ideal scanning line when a plurality of laser beams is scanned in a main scanning direction, a calculation unit to calculate a shape of the scanning line based on the misregistration amount stored, and to determine a scanning line curvature cancellation curve which cancels misregistration of the calculated shape of the scanning line, and an image forming unit to form an image that reflects the scanning line curvature cancellation curve by shifting image data which is read out from a memory unit in a sub scanning direction according to the scanning line curvature cancellation curve. The image forming unit corrects the amount of misregistration which is smaller than a main scanning line interval by adjusting a transfer point at which the image data is shifted in the sub scanning direction.

  • Publication number: 20100103441
    Abstract: A printer not optically correcting bends and inclinations of scanning lines needs to execute such control as to electrically correct them. However, a conventional correction method has a problem that this correction causes an image defect such as an image streak or an uneven density in a specific area. A correction method of the present invention, when an input image has only one color, executes only correction by a second correction component which corrects distortions in a main scanning direction without executing correction by a first correction component which corrects bends and inclinations in a sub-scanning direction, and when an input image has two or more colors, executes both of correction by the first correction component and correction by the second correction component. This control can reduce the frequency of occurrence of an image defect.
