Image Forming Apparatus Security Information Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming apparatuses struggle to reliably print security information when the QR code is printed only on part of the paper, leading to incomplete printing if the area without the QR code is scanned and copied.
Innovation Solution
An image forming apparatus that reads original documents, extracts security information, sets a print target area, and prints the security information along with the corresponding image data, ensuring that the QR code is included in the printed output even if it's not within the initially designated print area.

If security information such as a QR code is printed only on part of the paper, then the printing process is simplified and faster, but the security information may be omitted if an area without the QR code is scanned and copied
Solution Approach 1:
The system performs a preliminary scan of the entire original document before printing to detect the presence and location of security information such as QR codes. Based on this preliminary detection, the system automatically adjusts the print area to include the security information, ensuring it is not omitted during the printing process
Solution Approach 2:
The system uses feedback from the preliminary scan results to dynamically modify the printing parameters. The detection unit identifies security information locations, and this information feeds back to the control unit, which then adjusts the print area settings to ensure security information is included in the final output

AI summary
This invention provides an image forming apparatus capable of reliably printing security information even when image data of an original document that is obtained by a reading unit contains security information and an area where the security information is not contained is set as a print area, and a control method thereof. To accomplish this, when image data of an original document contains security information, the image forming apparatus extracts image the security information from data, and sets a print target area from an area indicated by the image data of the original document. When an area corresponding to, from which the security information is extracted, is not contained in the set print target area, the image forming apparatus executes printing using the extracted image data corresponding to the security information, and the image data corresponding to the print target area.
