Wireless Tag Retry Control in Image Forming Media Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face issues when writing information to wireless tags on media fail, leading to unnecessary retry processing with new media, which is against user intent when multiple tags are attached to a single medium.
Innovation Solution
The apparatus includes an interface, supply device, wireless communication device, image forming device, and processor to manage and control retry processing based on the success or failure of writing tag information, allowing user-controlled execution of retry operations to minimize waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the image forming apparatus automatically executes retry processing with a new medium when writing information to a wireless tag fails, then the system ensures complete image formation, but it causes waste of media and wireless tags when multiple tags are attached to one medium
Solution Approach 1:
The patent makes the retry processing dynamic by allowing users to specify whether retry should be executed globally or selectively for specific wireless tags. The control unit dynamically adjusts the retry behavior based on user input, enabling flexible control over which tags undergo retry processing and which are skipped, thus preventing unnecessary waste while ensuring reliable image formation where needed.
Solution Approach 2:
The patent applies local quality by enabling selective retry processing for individual wireless tags rather than forcing a global retry for all tags on a medium. Users can specify particular tags that require retry, allowing the system to apply different treatment to different parts of the same medium, thereby conserving resources on tags that don't need retry while maintaining reliability where necessary.
2Reliability
If the image forming apparatus executes retry processing for all wireless tags on a medium, then all tags are ensured to be processed, but it increases processing time and reduces productivity
Solution Approach 1:
The patent implements partial action by allowing users to specify only the necessary subset of wireless tags that require retry processing, rather than forcing a retry for all tags on the medium. This selective approach performs the minimum necessary retries to ensure reliability for problematic tags while skipping tags that are already successfully written, thereby reducing overall processing time and improving productivity.
3Ease of operation
If the image forming apparatus does not provide retry option to users, then the system operates automatically and simply, but it reduces user control over media usage and increases waste
Solution Approach 1:
The patent enables users to self-determine the retry processing strategy by providing an interface where users can specify whether retry should be executed and which tags should be targeted. This self-service approach allows users to control media usage according to their specific needs and preferences, preventing unnecessary waste while maintaining the ability for automatic operation when users choose default settings.

AI summary
According to an embodiment, an image forming apparatus communicates with a predetermined number of wireless tags of one or more supplied media on a basis of a printing job, and forms images on a predetermined number of printing regions corresponding to the wireless tags. The image forming apparatus outputs information for checking whether or not retry processing, which is executed in accordance with a failure to write tag information to the one or more wireless tags of the one or more media, is necessary and receives a request for the retry processing.
