Dual Toner Supply Sections for Image Quality Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming apparatuses lack the ability to easily switch between different toner cartridges with the same color but varying characteristics, making it cumbersome to achieve desired image quality or cost-effective image formation.
Innovation Solution
An image forming apparatus with detachable first and second supplying sections for different toner cartridges, allowing switching between image forming modes using either toner, along with a control system to select the appropriate toner based on user requirements and print job attributes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single toner cartridge is used in conventional image forming apparatuses, then the device complexity is low, but the adaptability to different user requirements (image quality vs. cost) deteriorates
Solution Approach 1:
The toner supply system is segmented into multiple independent supplying sections (first supplying section with first container, second supplying section with second container), each capable of being detached and replaced independently. This allows the system to adapt to different user requirements by selecting which supplying section to use, while maintaining manageable complexity through modular design.
Solution Approach 2:
The image forming apparatus is designed with multi-functionality by incorporating both a first image forming section and a second image forming section that can operate interchangeably. The control section provides universal control over both supplying sections, enabling the single device to serve multiple purposes (high image quality mode vs. cost-effective mode) without requiring separate apparatuses.
2Adaptability or versatility
If multiple toner cartridges with different characteristics are prepared, then the adaptability to user requirements improves, but the ease of operation deteriorates due to cumbersome cartridge replacement
Solution Approach 1:
The system dynamically switches between the first image forming section and the second image forming section based on user requirements. The control section enables dynamic mode switching (first image forming mode vs. second image forming mode) without requiring physical replacement of entire toner cartridges during operation, greatly improving ease of operation while maintaining adaptability.
Solution Approach 2:
The control section automatically manages the selection and switching between different toner supplying sections based on predetermined conditions or user preferences. This self-service capability eliminates the need for users to manually replace toner cartridges when switching between different image quality modes, significantly improving ease of operation.
3Productivity
If conventional single-mode image forming is used, then the device complexity is low, but the productivity in terms of meeting diverse user needs deteriorates
Solution Approach 1:
The image forming apparatus is segmented into functional modules (first supplying section, second supplying section, control section) that can operate independently. This segmentation allows the system to quickly adapt to different productivity requirements by activating the appropriate module, improving overall productivity in meeting diverse user needs while keeping each module relatively simple.
Solution Approach 2:
The control section provides universal control capabilities that manage both the first and second image forming sections. This multi-functional control system enables the apparatus to handle various user requirements (different image qualities, different cost preferences) within a single device, improving productivity in serving diverse needs without proportionally increasing complexity.

AI summary
Toners of the same color but with different characteristics are stored in the toner cartridges. For example, toners for high image quality (High Grade) with small particle diameter are stored in some toner cartridges and toners for low image quality (Low Grade) are stored in other toner cartridges. In this case, case, the mode of forming images using small particle diameter toner for high image quality using an image forming engine and the mode of forming images using a toner for low image quality using another image forming engine are executed by the image forming apparatus.
