Disclosed is an image forming system that includes: a sheet conveyance section that conveys a continuous sheet along a sheet conveyance path; an image forming section that forms an image on the continuous sheet; and an image reading section that is disposed downstream of the image forming section in the sheet conveyance path, and reads the image formed on the continuous sheet to generate image data; and a hardware processor that determines, based on the read image data, whether or not there is an image defect, and determines, based on a result of the determination regarding the image defect, whether or not to perform reprinting of an image that is determined to have an image defect. The hardware processor continues operation of the image forming section until determining not to perform the reprinting.

Continuous sheet image forming system with improved defect correction and reprinting

An image forming apparatus includes: a conveyer that conveys continuous paper through a conveying path; a detector that detects a mark on the continuous paper conveyed by the conveyer; an image former that is provided on a subsequent stage side of the detector and forms an image on the continuous paper; and a hardware processor that causes the image former to start forming an image according to a position setting for forming an image on the continuous paper using the image former after a mark on the continuous paper is detected, wherein the hardware processor adjusts the position setting on the basis of a start position determined according to an image formation state.

Image forming apparatus

An image forming apparatus of the present invention includes: an image forming unit for forming an image on a continuous paper; a fixing unit for fixing by heat the image which has been formed on the continuous paper by the image forming unit; conveyance units for conveying the continuous paper; and a control unit for controlling the conveyance units to convey the continuous paper in such a manner that, when an image forming operation by the image forming unit is stopped, the same portion of the continuous paper, on which the image is not formed, does not remain in the fixing unit for a predetermined period of time.

Image forming apparatus that controls movement of a continuous sheet through a fixing unit

An image forming system includes a sheet conveyance unit, an image forming unit, a fixing unit and a controller. The sheet conveyance unit conveys continuous paper. The image forming unit forms an image on the continuous paper. The fixing unit fixes the image formed on the continuous paper. The controller controls an image forming operation performed by the sheet conveyance unit, the image forming unit and the fixing unit. In a case where a waste paper reduction mode is selected, the controller controls the sheet conveyance unit to stop conveying the continuous paper so that a bottom end of a last image on the continuous paper be at a second stop position on an upper-stream side of a first stop position after the bottom end of the last image passes the fixing unit when ending the image forming operation.

Image forming system for reducing waste paper

An image forming device includes: a paper feeding unit configured to feed continuous form paper; an image forming unit configured to form an image on the continuous form paper; a fixing unit configured to fix the image formed on the continuous form paper; a measuring unit configured to measure a temperature of the fixing unit; and a control unit configured to control an operation of each of the paper feeding unit, the image forming unit, and the fixing unit, wherein when detecting a trouble with which feeding of the continuous form paper is suspended, the control unit performs determination processing of determining whether to prompt a user to execute removal of a part of the continuous form paper, which part is influenced by heat from the fixing unit, according to the temperature of the fixing unit which temperature is measured by the measuring unit in the detection of the trouble.

Image forming device, image forming system, and program

An image forming apparatus includes an image forming section that performs processing for forming an image on continuous paper on the basis of image data and a processor configured to perform image preparation to convert the printing data into the image data and control the image forming section to execute forming of an image on the continuous paper based on the image data. The processor is further configured to perform, before the image formation, second forming speeds setting according to image sizes in a paper passing direction, predetermined first image forming speeds, and image preparation times related to the images.

Image forming apparatus, image printing method, and computer-readable recording medium having stored therein image printing control program

An image forming device includes an image forming unit configured to continuously form images on continuous paper, a conveying unit configured to convey the continuous paper, and a control unit configured to start an image quality adjusting operation for adjusting image quality of a subsequent image to be formed by the image forming unit after formation of a last image by the image forming unit is completed while the conveying unit conveys the continuous paper until the last image arrives at a predetermined position.

Image forming device, image forming method, and image forming program

An image forming apparatus includes an image forming section that performs processing for forming an image on continuous paper on the basis of image data and a control section that performs image preparation for converting printing data into image data from which an image can be formed and controls the image forming section to execute printing of a plurality of images at equal intervals on the continuous paper. The control section performs, before the image formation processing, according to image sizes in a paper passing direction, image forming speeds, and image preparation times related to the images, printing condition setting for setting an interval of the images.

Disclosed is an image forming apparatus that includes an image forming section, a conveyance section, a position detecting section, an abnormality detecting section and a control section. When determining as the first determination that it is possible to eject each of the paper sheets and/or the image-formed paper sheets outside and determining as the second determination that it is necessary to re-output the new image-formed paper sheet, the control section incompletely ejects each of the retention paper sheets, remaining within the image forming apparatus, outside from the ejection opening. By controlling the apparatus as above-mentioned, even in a case where it is impossible to eject the concerned paper sheet onto a separate tray, it becomes possible to prevent the retention paper sheet from remaining at an apparatus-inner position, from which it is difficult for the user to remove the retention paper sheet concerned.
