Dynamic Print Speed Switching for Mixed Sheet Types
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multifunction peripherals (MFPs) face productivity decreases due to time wasted switching print speed modes when printing multiple sheet types, especially when a mix of sheet types requires different print speeds.
Innovation Solution
A printing apparatus equipped with a determination unit to assess print speed needs, a switching unit to dynamically adjust print speeds during printing, and an analysis unit to evaluate the productivity impact of speed switches based on the mix of sheet types in the print job.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If print speed modes are switched when printing multiple sheet types, then printing quality is improved for each sheet type, but productivity of printing decreases due to time wasted on switching
Solution Approach 1:
The analysis unit performs preliminary analysis of print job data before printing to identify sheet type transitions. The determination unit pre-determines optimal print speed modes for each sheet type sequence, allowing the switching unit to execute pre-planned speed changes without interruption or downtime, thus maintaining both printing quality and productivity
2Productivity
If print speeds are maintained constant for all sheet types, then productivity of printing is improved, but printing quality deteriorates for certain sheet types that require specific print speeds
Solution Approach 1:
The system dynamically adjusts print speed modes during the printing process based on real-time sheet type detection. The switching unit changes print speeds adaptively when transitioning between different sheet types, ensuring each sheet type receives optimal print speed for quality while minimizing overall printing time through efficient transition management
3Adaptability or versatility
If the number of print speed modes is increased to accommodate more sheet types, then adaptability of the printing apparatus is improved, but device complexity increases
Solution Approach 1:
The system manages multiple print speed modes through parameter-based control where each sheet type is associated with specific print speed parameters. The determination unit selects appropriate parameters based on sheet type analysis, allowing the apparatus to handle diverse sheet types using a structured parameter system rather than complex mechanical configurations
