Failure Source Identification in Image Forming Management Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional management systems for image forming apparatuses cannot distinguish between failures in the apparatus itself and external devices providing network functions, leading to unnecessary service dispatches and wasteful costs, as they assume all defects originate from the image forming apparatus.
Innovation Solution
A management system with a determination unit in the image forming apparatus to identify whether failures are caused by the apparatus or external providing apparatuses, creating and transmitting appropriate failure information to a management server, which then notifies maintenance personnel only if the failure is confirmed to be within the apparatus, avoiding unnecessary maintenance dispatches for external device issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the management server dispatches service personnel based on failure notifications from the image forming apparatus without determining the failure source, then the response speed is improved, but unnecessary dispatches occur and costs increase
Solution Approach 1:
The determination unit performs preliminary analysis to identify whether the failure originated from the image forming apparatus or external device before the management server dispatches service personnel. This preliminary action prevents unnecessary dispatches while maintaining quick response for actual apparatus failures.
Solution Approach 2:
The determination unit acts as an intermediary between the image forming apparatus and management server, analyzing failure causes and providing informed failure information. This intermediary function enables the management server to make accurate dispatch decisions without delaying the response process.
2Device complexity
If the management server assumes all failures originate from the image forming apparatus, then the simplicity of the management system is maintained, but measurement precision of failure source is degraded
Solution Approach 1:
The failure analysis function is segmented into a dedicated determination unit within the image forming apparatus, separate from the management server. This segmentation enables precise failure source identification while keeping the management server's role focused on coordination and dispatch decisions.
Solution Approach 2:
The image forming apparatus performs self-diagnosis through its determination unit to identify failure sources and generate accurate failure information. This self-service capability eliminates the need for complex server-side analysis while improving failure source identification accuracy.

AI summary
A management server capable of communicating with a providing apparatus via a network and using a function provided by the providing apparatus includes a reception unit configured to receive failure information from the image forming apparatus, and a notification unit configured to perform notification for arranging maintenance of the image forming apparatus according to the failure information received from the image forming apparatus, wherein the management server does not arrange the maintenance of the image forming apparatus if it can be identified that the failure is caused by the providing apparatus based on the received failure information.
