Dual Communicator Switching for Image Forming Apparatus Network Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face issues with transmitting consumable component information via external networks, as failures in these networks prevent the transmission of critical usage and state information to management servers.
Innovation Solution
Incorporating dual communicators within the image forming apparatus, allowing it to switch communication to a secondary network if an abnormality occurs in the primary network, ensuring continuous transmission of usage and state information to the management server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single network communicator is used to transmit usage and state information to the management server, then the device complexity is reduced, but the reliability of information transmission is compromised when network failures occur
Solution Approach 1:
The communication system is segmented into multiple independent communicators (first communicator and second communicator), each capable of independently transmitting information to the management server. This segmentation ensures that a failure in one communicator does not affect the other, thereby improving reliability without requiring complex coordination between multiple systems.
Solution Approach 2:
A second communicator is prepared in advance as a backup communication path. When the first communicator fails, the controller switches to the second communicator without interruption, cushioning against the impact of network failures before they occur. This pre-prepared redundancy ensures continuous information transmission to the management server.
2Reliability
If dual communicators are implemented to ensure continuous transmission during network failures, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The system dynamically switches between the first communicator and the second communicator based on real-time network status. The controller monitors the status of communicators and automatically transitions from the primary to the backup communicator when failures are detected, providing adaptive reliability without static over-engineering.
Solution Approach 2:
The controller acts as an intermediary that manages both communicators and coordinates the switching between them. By centralizing the management of communication paths in the controller, the system avoids the complexity of independent decision-making in each communicator and simplifies the overall architecture.
3Loss of information
If the first communicator is used for all transmissions, then the ease of operation is improved, but the loss of information increases during network failures
Solution Approach 1:
The controller continuously monitors the status of the first communicator and receives feedback about its operational health. When network failures are detected through this feedback mechanism, the system automatically activates the second communicator to maintain information transmission, preventing data loss without requiring manual intervention.
Solution Approach 2:
The system performs self-diagnosis and self-repair by automatically detecting communicator failures and switching to the backup path without external intervention. This self-service capability maintains information transmission continuity while keeping the operation simple for users, as they do not need to manually manage communication failures.

AI summary
Provided is an image forming apparatus including a controller, a communicator that communicates with a management server, and an image former that forms an image. The communicator includes a first communicator and a second communicator. The controller transmits usage information of the image forming apparatus and state information of the image forming apparatus to the management server via the first communicator, and if an abnormality occurs in the first communicator, the controller transmits the usage information of the image forming apparatus or the state information of the image forming apparatus to the management server via the second communicator.
