Description

The present invention relates to an image forming system , management device, and program capable of determining image defects on a transfer medium.

2. Description of the Related Art In the field of image forming apparatuses that print images on paper, it is one of the problems to check whether printed matter that has been output is correctly printed. Therefore, various methods have been proposed for checking the quality of images on printed matter.
For example, in Patent Document 1, when outputting a print job, page data is extracted as a sample, the extracted page data can be displayed on a display, and it is possible to compare and check the output printed matter. However, it has the disadvantage that it is difficult to operate because the user needs to be attached to the machine in order to check the comparison of the printed matter.

Further, Japanese Patent Application Laid-Open No. 2002-200000 discloses reading an image of an output printed matter with a scanner, reducing the read image to generate a thumbnail, and printing out the thumbnail after the output of the job is completed. With the technique disclosed in Patent Document 2, even when outputting a plurality of jobs, it is possible to efficiently check for waste without lowering productivity by collectively confirming waste after output of the jobs is completed. However, there is a drawback in that it is difficult to detect distortion with high precision with reduced thumbnails.

This tab may be displayed on top when other tabs are overlapped and the tab is pressed. When the output of a job is completed, the tab displaying the history of output jobs is automatically displayed. may be displayed on the top surface.

The paper is then transported to the reading device 30 via the relay device 20 . In the reading device 30, when an image is formed on one side of the back surface of the paper, the image is read by the image reading section 31, and when an image is formed on one side of the front side of the paper, the image is read by the image reading section 32. . When images are formed on both sides of the paper, the image reading units 31 and 32 read the images.

Next, description will be given of the operation of displaying a job including a waste in an identifiable manner in the output history display when a waste is detected. The history may be presented automatically at a predetermined timing such as after the job is finished, or may be presented based on the user's operation.

The control CPU 113 determines whether or not the image has defects by comparing the reading result read by the reading device 30 with the image data for printing. However, if an image defect (worn image) is detected, the user must check the damaged image. From the standpoint of productivity, the user should confirm the damaged image after all jobs have been output. desirable. Therefore, even when a plurality of jobs are output, it is required to be able to easily confirm in which job and at what point a waste is detected among the created products.
