Printer Control Portion Omits Common Printing Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid ejecting apparatuses, such as printers, face a limitation in reducing the time from power supply to the start of the recording operation due to the inclusion of detecting the amount of remaining ink in the initial operation, which can be omitted only when power is normally cut off.
Innovation Solution
A liquid ejecting apparatus and method that execute an initial operation upon power supply, including a common printing operation, where the control portion omits this operation if a print instruction is received during its execution, thereby reducing the initial operation time by excluding common operations shared with the printing operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the initial operation includes detecting the amount of remaining ink, then the printing quality and reliability are ensured, but the initial operation time increases
Solution Approach 1:
The patent applies dynamics by making the initial operation configuration flexible and adaptable. The control portion dynamically determines whether to include the common printing operation based on real-time detection of print instructions. When a print instruction is received during the initial operation, the system dynamically adjusts by omitting the common printing operation, thereby reducing initial operation time while ensuring printing quality when needed.
2Manufacturing precision
If the common printing operation is always executed in the initial operation, then the printing quality is maintained, but the efficiency of the liquid ejecting process decreases
Solution Approach 1:
The patent applies partial action by selectively executing only the necessary portion of the common printing operation. Instead of always executing the complete common printing operation, the control portion determines the appropriate scope based on whether a print instruction has been received. When a print instruction is present, only the essential printing operations are performed, omitting redundant steps, thus maintaining printing quality while improving efficiency.
3Loss of time
If the initial operation is shortened by omitting the common printing operation, then the initial operation time is reduced, but the printing quality may be compromised
Solution Approach 1:
The patent applies feedback by using the detection result of the print instruction to control the execution of the common printing operation. The control portion continuously monitors for print instructions during the initial operation and uses this feedback information to determine whether to include or omit the common printing operation. This feedback mechanism ensures that printing quality is maintained when print instructions are present while allowing time reduction when they are not.

AI summary
A liquid ejecting apparatus includes a printing portion and a control portion. The printing portion executes a printing operation including ejecting a liquid from a nozzle onto a medium. The control portion executes an initial operation upon supply of power and executes the printing operation in accordance with a print instruction. The initial operation and the printing operation include a common printing operation that is common to the initial operation and the printing operation. When the control portion does not receive the print instruction during execution of the initial operation, the control portion executes the initial operation including the common printing operation. When the control portion receives the print instruction during execution of the initial operation, the control portion omits the common printing operation from the initial operation.
