Controller Operation Panel Connection Error Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face challenges in detecting connection errors between the operation panel and controller efficiently, often requiring unnecessary time to determine if the controller has activated and established communication, leading to increased detection time for malfunctions.
Innovation Solution
The apparatus performs a first determination process to check if the controller's activation is completed within a predetermined time after the operation panel's activation and a second determination process to verify communication establishment, allowing for early detection of connection errors without waiting for unnecessary time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the apparatus waits for a long period to determine controller activation completion and communication establishment, then detection accuracy is improved, but detection time increases
Solution Approach 1:
The determination process is segmented into multiple stages: first determining whether the controller has completed activation, then second determining whether communication is established. This staged approach allows the system to check for errors at intermediate points rather than waiting for the complete process, thereby reducing detection time while maintaining accuracy through systematic verification at each stage.
Solution Approach 2:
The system performs preliminary determination of controller activation status before final communication establishment verification. By checking activation completion first and preparing for communication verification in advance, the system can detect errors earlier in the process without compromising the accuracy of the final determination.
2Ease of operation
If the apparatus uses fixed predetermined periods for determination, then ease of operation is improved, but adaptability to different activation speeds worsens
Solution Approach 1:
The predetermined periods are made dynamic rather than fixed. The first predetermined period for determining controller activation is adjusted based on actual measured activation times, and the second predetermined period for communication establishment is similarly adapted. This allows the system to maintain ease of operation through automated determination while adapting to varying activation speeds of different controllers.
Solution Approach 2:
The time parameters (predetermined periods) are changed based on actual system performance measurements. By measuring actual activation times and communication establishment times, the system adjusts the determination periods to match real-world variability, thereby maintaining both operational simplicity and adaptability to different hardware characteristics.

AI summary
An information processing apparatus, a method, and a non-transitory recording medium. The information processing apparatus, in a case the controller completes an activation after the operation panel completes an activation, detects a connection error between the operation panel and the controller by performing a first determination process of determining whether activation of the controller is completed within a first predetermined period of time after activation of the operation panel is completed and by performing a second determination process of determining whether communication between the operation panel and the controller is established within a second predetermined period of time after completion of the activation of the controller, and in a case the controller completes the activation before the operation panel completes the activation, detects the connection error between the operation panel and the controller by performing the second determination process.
