Print Mode Ink Control for Clear Low-Ink Document Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording apparatuses face issues with unclear images due to low image density when the amount of recording material is insufficient, particularly in modes where adjustments are not feasible, leading to the need for re-recording important documents like contracts.
Innovation Solution
The recording apparatus is configured with a controller that adjusts the amount of recording material in multiple modes, with a narrower range of reduction in one mode to prevent issues, ensuring clear image recording without requiring re-transmission of data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the amount of recording material is reduced to save resources, then productivity is improved, but image density decreases causing unclear images
Solution Approach 1:
The patent implements dynamic control of recording material amount by providing multiple recording modes (first mode with smaller reduction, second mode with larger reduction) that can be selected based on recording conditions. The controller dynamically adjusts the amount of recording material according to the selected mode, allowing optimization between productivity and image quality for different scenarios.
Solution Approach 2:
The patent changes the parameter of recording material amount by introducing different adjustment widths for different modes. In the first mode, the adjustment width for decreasing recording material is smaller, while in the second mode, it is larger. This parameter change allows flexible control over the balance between resource conservation and image quality.
2Loss of substance
If the amount of recording material is reduced excessively, then loss of substance is improved, but reliability decreases due to unclear images requiring re-recording
Solution Approach 1:
The system dynamically switches between different recording modes depending on the situation. When resource conservation is prioritized, the second mode with larger reduction is used. When reliability is critical, the first mode with smaller reduction maintains better image quality, preventing the need for re-recording and thus improving overall reliability.
Solution Approach 2:
The patent applies beforehand cushioning by setting conservative limits on recording material reduction in the first mode. This prevents excessive reduction that would lead to unclear images, thereby cushioning against the risk of re-recording being needed. The controller proactively maintains sufficient recording material amount to ensure image quality before problems occur.
3Ease of operation
If uniform adjustment of recording material is applied across all modes, then ease of operation is improved, but adaptability decreases for different recording scenarios
Solution Approach 1:
The patent segments the recording operation into different modes (first mode and second mode) with different adjustment characteristics. Each mode is optimized for specific scenarios: the first mode for situations requiring higher image quality, and the second mode for situations prioritizing resource conservation. This segmentation allows both simple operation within each mode and adaptability across different scenarios.
Solution Approach 2:
The controller is designed with multi-functionality to handle different recording modes and adjustment widths within a single device. This universal design allows the same recording apparatus to adapt to various recording scenarios (important documents vs. regular prints) without requiring separate devices, maintaining ease of operation while providing adaptability.

AI summary
There is provided a recording apparatus including: a recording part configured to perform, with a recording material, a recording of an image with respect to a recording medium; and a controller configured to control the recording part in a plurality of modes. The plurality of modes includes a first mode and a second mode. The controller is configured to adjust an amount of the recording material to be used at a time of the recording in the second mode. An adjustment width in a direction of decreasing the amount of the recording material in the first mode is smaller than an adjustment width in the direction of decreasing the amount of the recording material in the second mode.
