Problems solved by technology

[0004] However, in Japanese Patent Application Laid-Open No. 2010-215385, since only paper with a page number becomes the detection object of waste paper, it is impossible to detect waste paper for paper without a page number.
In addition, in Japanese Patent Laid-Open No. 2007-310567, it is necessary to set an image area to be detected, or perform image processing on a comparison image for comparison with an output image according to the state of paper (paper color, overprint, etc.), and Waste paper is detected based on part of the image formed on the paper, so paper with poor image formation in other parts cannot be detected as waste paper

Embodiment approach 1

[0031] Hereinafter, Embodiment 1 of the present invention will be described in detail with reference to the drawings.

[0032] First, the configuration will be described.

[0033] figure 1 A schematic cross-sectional configuration diagram of the image forming system in Embodiment 1 is shown.

[0034] Such as figure 1 As shown, the image forming system 1 has a configuration in which an image forming device 10 , an output image reading device 20 , a post-processing device 30 , and the like are connected from the upstream side of the paper conveyance path.

[0035] The image forming apparatus 10 reads an image from a document, and forms the read image on paper as an image, or receives a page description language format such as a PDL (Page Description Language) format or a Tiff format from an external device or the like. and print setting data in which various output instructions for the print data are set, and based on the received print data and print setting data, an image i...

Embodiment approach 2

[0153] Hereinafter, Embodiment 2 of the present invention will be described in detail with reference to the drawings.

[0154] First, the configuration will be described.

[0155] The schematic configuration diagram of the image forming system in Embodiment 2 is the same as that in Embodiment 1, and therefore illustration and description thereof will be omitted.

[0156] Figure 8 A control block diagram of the image forming system 1 in Embodiment 2 is shown in .

[0157] Such as Figure 8 As shown, the image forming system 1 is composed of an image forming device 10 , an output image reading device 20 and a post-processing device 30 .

[0158] However, the same reference numerals are assigned to the same components as those in Embodiment 1, and description thereof will be omitted, and only different components will be described.

[0159] The image control board 15 has a control unit 150, a nonvolatile memory 151, a RAM (Random Access Memory) 152, a read processing unit 15...

Abstract

Disclosed is an image forming system (1) including: an output image reading control section (210) reading an image formed on each of output materials to generate output image data when the image is formed on paper and the output materials are obtained by printing-out based on job data in which a plural-copy-execution number is set; a storage section (156) storing output image data of a first output material generated by the output image reading control section as comparison image data; and a control section (150) which compares the comparison image data with the output image data for determining whether the comparison image data and the output image data are same and stops the action related with printing output based on operation data when the output image data is not identical with the comparison image data.

Description

technical field [0001] The present invention relates to an image forming system. Background technique [0002] In recent years, there is an image forming system that has a function of automatically or by a user judging whether an appropriate image is formed on paper, for example, whether there is stain, whether the position is shifted, whether the appropriate color is expressed, etc. , and paper (hereinafter referred to as waste paper (waste paper sheet)) judged to have not formed an appropriate image (defective image formation) is detected. [0003] For example, as the detection of (wrong pages) waste paper in which the order of the pages is disordered, a technology of reading the page number on the paper and monitoring the continuity of the read page number to detect the waste paper has been disclosed (refer to Japanese Patent No. Publication No. 2010-215385). In addition, among the techniques for checking the printed content in the printout using the preprinted paper in...
