Image Forming Apparatus Paper Attribute Logging During Job Interruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face challenges in accurately managing job execution results for each paper type due to the timing of acquiring paper attribute information, which can lead to incomplete or inaccurate data when the intended paper attribute information is not transmitted, especially during job interruptions.
Innovation Solution
An image forming apparatus capable of transmitting paper attribute information set during job interruptions, including both pre-change and post-change attribute information, to a management server, ensuring accurate logging and aggregation of job execution data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If paper attribute information is acquired at the start of a job, then the timing is simple and fixed, but the information may be incomplete or inaccurate when paper is loaded during job interruption
Solution Approach 1:
The system performs preliminary acquisition of paper attribute information at the start of the job, stores it, and then performs a second acquisition when the job is resumed after interruption. This ensures that the final log contains accurate paper attribute information corresponding to the actual paper used, resolving the contradiction between simple timing and information accuracy.
2Loss of information
If paper attribute information is acquired only at job completion, then the logging is simplified, but the information does not reflect paper changes during job interruption
Solution Approach 1:
The system maintains continuous tracking of paper attribute information by acquiring data at job start, preserving it through interruption, and updating it at job resumption. This continuous approach ensures complete job execution data is captured without requiring constant processing, balancing information completeness with processing efficiency.
3Measurement precision
If the system tracks paper attribute changes during job interruption, then data accuracy improves, but the processing complexity increases
Solution Approach 1:
The system dynamically adjusts its information acquisition strategy based on job status. It acquires paper attribute information at job start, monitors for interruption conditions, and automatically performs additional acquisition when resumption is detected. This dynamic approach achieves precise recording without requiring complex continuous monitoring throughout the entire job lifecycle.

AI summary
An image forming apparatus capable of transmitting paper attribute information set during job interruption. The image forming apparatus, which has an image forming device and a paper feeding part storing paper and is communicable with a management server, holds paper attribute information in association with the paper feeding part, executes an image forming job that causes the image forming device to perform a series of image forming using the paper stored in the paper feeding part, generates an execution log of the image forming job based on the attribute information, and when the attribute information corresponding to the paper feeding part is changed during the execution of the image forming job, generates an execution log including the attribute information before/after the change and transmits the generated execution log to the management server.
