Image Stabilization Control for Speed-Switchable Printers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inefficiency in image stabilization processes for image forming devices at customer sites, where servicemen often forget to perform two-stage image stabilization due to lack of knowledge about model changes, leading to decreased setup efficiency and potential failure in stabilization.
Innovation Solution
An image forming device equipped with a license accepting mechanism, system speed switching capability, and automatic determination of stabilization processes based on stored information, performing two-stage stabilization when system speed changes are detected and single-stage stabilization when no changes are found, thereby reducing the need for manual intervention and ensuring stabilization is performed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If two-stage image stabilization is performed, then image formation quality is optimized, but time required for stabilization increases significantly
Solution Approach 1:
The patent applies dynamics by making the image stabilization process adaptive rather than fixed. The control unit dynamically selects between two-stage and single-stage stabilization based on real-time detection of system speed changes. When speed changes are detected, the system performs comprehensive two-stage stabilization; when no changes are detected, it performs faster single-stage stabilization. This dynamic adaptation resolves the contradiction by adjusting the stabilization depth according to actual system conditions.
Solution Approach 2:
The patent changes the parameter of stabilization process intensity based on system speed change detection. By monitoring whether system speed has changed since the last stabilization, the control unit adjusts the stabilization approach - using full two-stage process when parameters may have shifted significantly, and abbreviated single-stage process when parameters remain stable. This parameter-based decision-making optimizes both quality and time efficiency.
2Manufacturing precision
If servicemen manually perform two-stage image stabilization, then image formation quality is ensured, but setup efficiency decreases due to human error and lack of knowledge
Solution Approach 1:
The patent implements self-service by enabling the image forming device to automatically determine and execute the appropriate stabilization process without requiring servicemen's intervention. The control unit autonomously detects system speed changes, decides whether two-stage or single-stage stabilization is needed, and executes the process automatically. This eliminates human error, removes the burden of servicemen's knowledge requirements, and significantly improves setup efficiency while maintaining image formation quality.
Solution Approach 2:
The patent uses feedback mechanisms where the control unit continuously monitors system speed parameters and uses this information to determine the appropriate stabilization approach. The system feeds back the detected speed change information to the stabilization control logic, which then selects the appropriate process. This closed-loop feedback ensures that stabilization is performed based on actual system conditions rather than manual assumption, improving both efficiency and reliability.
3Adaptability or versatility
If system speed is switched to differentiate device models, then device versatility is improved, but image stabilization reliability decreases due to uncertain model changes
Solution Approach 1:
The patent applies preliminary action by detecting system speed changes before performing image stabilization. The control unit proactively monitors the system speed parameter and identifies changes that indicate model differentiation. By detecting these changes in advance, the system can prepare to perform appropriate stabilization before image formation begins, ensuring reliability is not compromised by the versatility of speed switching. The preliminary detection of speed changes enables timely stabilization execution.

AI summary
An image forming device (1) switches a system speed when assignment of a license has been accepted (S118), and stores switching information of the system speed (S217). The image forming device (1) performs two-stage image stabilization for determining a setting value of a parameter relating to an image formation process of the image forming device (1) when the switching information of the system speed is stored (S205), and performs single-stage image stabilization for determining a setting value of the parameter relating to the image formation process of the image forming device (1) when the switching information of the system speed is not stored (S209).
