Solution Overview
Problem
Conventional inkjet recording apparatuses face challenges in achieving consistent image quality due to manufacturing errors and individual differences in recording heads, leading to excessive consumption of recording sheets and ink for density characteristics acquisition processing.
Innovation Solution
An information processing apparatus that determines the execution of density characteristics acquisition processing based on specific settings and conditions, such as the completion of a feeding operation, to optimize the frequency of this processing and reduce unnecessary consumption of resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If density characteristics acquisition processing is executed frequently to ensure color stability, then image quality consistency is improved, but consumption of recording sheets and ink increases excessively
Solution Approach 1:
The system changes the execution parameter of density characteristics acquisition processing from frequent execution to conditional execution based on specific triggers (power on, head replacement, medium replacement). This parameter change reduces consumption while maintaining color stability through targeted execution at critical moments when recording characteristics are most likely to change.
Solution Approach 2:
The recording apparatus automatically determines whether to execute density characteristics acquisition processing based on internal state monitoring (power status, head replacement detection, medium replacement detection) without requiring external intervention. This self-service mechanism ensures color stability is maintained while avoiding unnecessary processing that would consume resources.
2Measurement precision
If density characteristics acquisition processing is executed every time to ensure accurate recording characteristics, then measurement precision is improved, but productivity decreases due to excessive processing frequency
Solution Approach 1:
The execution frequency parameter of density characteristics acquisition processing is changed from constant (every time) to variable (conditional based on power on, head replacement, or medium replacement). This allows the system to maintain measurement precision when needed while improving overall productivity by avoiding redundant processing during normal operation.
Solution Approach 2:
The system performs density characteristics acquisition processing in advance at specific trigger points (power on, head replacement, medium replacement) before actual recording operations begin. This preliminary action ensures accurate recording characteristics are established beforehand, eliminating the need for repeated processing during subsequent operations and thus improving productivity.
3Manufacturing precision
If density characteristics acquisition processing is executed frequently to compensate for manufacturing errors and aging variations, then manufacturing precision compensation is improved, but loss of time increases due to repeated processing
Solution Approach 1:
The execution parameter of density characteristics acquisition processing is changed from frequent execution to execution only at critical moments (power on, head replacement, medium replacement). This parameter change reduces time loss while maintaining manufacturing precision compensation by targeting execution when recording characteristics are most likely to change due to manufacturing variations or aging.
Solution Approach 2:
The system performs density characteristics acquisition processing in advance at specific trigger points before actual recording operations. This preliminary action compensates for manufacturing errors and aging variations beforehand, eliminating the need for repeated processing during normal operation and thus reducing time loss while maintaining precision.
