Image Forming Apparatus Wireless Tag Heating Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image forming apparatuses often lose printed images on wireless tags due to heating, as the wireless tag region is not properly heated during the image fixation process, leading to defects and incomplete printing.
Innovation Solution
The image forming apparatus selectively heats regions on the print medium that do not include wireless tags, using a control unit to determine the non-heating regions and adjust the image formation area to prevent overlap and ensure complete image fixation without damaging the wireless tags.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire print medium is heated to fix the image, then the image fixation is complete, but the wireless tag generates defects due to heating
Solution Approach 1:
The patent applies local quality by creating different thermal treatment zones on the print medium. The heating unit selectively heats only the non-tag regions while leaving tag regions unheated. This is achieved by controlling the heating parameters (temperature, time, position) to match the tag positions, ensuring that each region receives appropriate treatment: complete heating for image fixation in non-tag areas, and no heating for tag preservation in tag areas.
2Reliability
If the wireless tag region is excluded from heating, then the wireless tag is protected from defects, but the image in the tag region is lost without being printed
Solution Approach 1:
The patent applies preliminary action by performing image processing to detect and identify tag regions before the actual printing and heating processes. The control unit receives image data, detects wireless tag positions, and determines which regions should be excluded from heating. This preliminary detection and planning ensures that subsequent printing and heating operations can proceed without losing image data in tag regions, as the system has already mapped out the safe zones to avoid.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution effectively prevents wireless tag defects while maintaining complete image formation on the print medium, ensuring that images are not lost during the printing process.
Implementation Method 1
The fixing unit includes a plurality of heat generating bodies or components... heats at least a portion of the region on the print medium... and fixes the toner image formed on the print medium as the target image to the print medium by heating the print medium

AI summary
A method for printing on a print medium includes acquiring print information regarding a target image to be applied to the print medium; acquiring position information from a reader regarding a position of a wireless tag on the print medium; determining a heating region based on the print information and a non-heating region based on the position information; determining whether the heating region and the non-heating region at least partially overlap; performing an image adjustment process to manipulate the target image to eliminate an overlap between the heating region and the non-heating region in response to determining that the heating region and the non-heating region at least partially overlap; controlling an image forming assembly to apply a toner image of the target image to the print medium; and controlling a fixing device to heat the toner image to fix the toner image on the print medium.
