Image forming device and image forming system

Abstract

An image forming apparatus (10) includes an identification-mark making unit (60). The identification-mark making unit (60) makes a page identification mark (11,12,13,14,12a,13a,13b) for identifying a page, on a predetermined position of a paper sheet during printing. The identification-mark making unit (60), based on the page identification mark (11,12,13,14,12a,13a,13b) made in a previous printing, includes a correction / addition mark (12a1,13a1,13b1) that indicates an existence of a correction page or an additional page since the previous printing in a part of the page identification mark (11,12,13,14,12a,13a,13b) when a new print output is performed.

Description

technical field [0001] The present invention relates to an image forming apparatus and an image forming system, for example, an image forming apparatus and an image forming system having a function of adding page information to output paper. Background technique [0002] Conventionally, a technique is known in which marks are printed offset from the ends of paper in the order of pages when printing is performed by an image forming apparatus. In this technology, the order of pages and the situation of missing pages can be confirmed immediately even by human eyes. [0003] However, in the above-mentioned prior art, a method capable of confirming the sequence based on the mark is proposed, but there is a problem that, when a page is corrected, it cannot be determined whether the correct replacement is performed on the corrected page, Or when a page is corrected or added, it becomes impossible to immediately determine whether the order of the pages in the corrected part is corr...

AI Technical Summary

Problems solved by technology

[0003] However, in the above-mentioned prior art, a method capable of confirming the sequence based on the mark is proposed, but there is a problem that, when a page is corrected, it cannot be judged whether the correct replacement is performed on the corrected page, Or when a page is corrected or added, it becomes impossible to immediately determine whether the order of the pages in the corrected part is correct by human eyes

When simply adding pages, the same marks (page identification mark 113 and additional page identification mark 113x) are aligned, and it is impossible to judge whether the order is correct

In addition, if the same mark is added, it cannot be judged what state the page is added
