Recording Head Height Adjustment During Media Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inkjet printers experience decreased productivity due to the time-consuming carriage height adjustments required for recording on various media types.
Innovation Solution
A recording apparatus with discharge rollers and a height-change member that allows for simultaneous discharge operations and parallel adjustment of the recording head height, independent of the discharge process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the carriage height is adjusted for recording on various media types, then recording quality is improved, but productivity decreases due to time-consuming height adjustments
Solution Approach 1:
The carriage height is adjusted in advance before the discharge operation begins, so that when the discharge operation starts, the height adjustment is already complete. This allows the recording head to be at the correct height for the specific media type without delaying the discharge operation.
Solution Approach 2:
The carriage height is adjusted periodically based on the media type being processed. The system determines the media type and adjusts the carriage height accordingly in a periodic manner, allowing optimization for each media type while maintaining overall process efficiency through parallel discharge operations.
2Adaptability or versatility
If the carriage height is changed for different media types, then adaptability is improved, but loss of time increases due to sequential operations
Solution Approach 1:
The carriage height adjustment is performed as a preliminary action before the discharge operation. The system determines the required height based on media type and completes the adjustment in advance, ensuring adaptability to different media types without causing time loss during the discharge process.
Solution Approach 2:
The carriage height is adjusted periodically according to the media type being processed. This periodic adjustment strategy allows the system to adapt to different media types while minimizing time loss by coordinating height changes with the periodic nature of discharge operations.
3Measurement precision
If the carriage height is adjusted during recording operations, then recording accuracy is improved, but productivity decreases due to operation sequencing
Solution Approach 1:
The carriage height adjustment is executed as a preliminary action before the discharge operation commences. This ensures that the recording head is positioned at the optimal height for accurate recording on the specific media type, while the discharge operation proceeds without interruption, thereby maintaining both recording accuracy and productivity.
Solution Approach 2:
The carriage height is adjusted periodically based on the media type and recording requirements. This periodic adjustment ensures recording accuracy for each media type while coordinating with the periodic discharge operations to maintain overall productivity.
