Ejection State Determination Method, Ejection State Determination Apparatus, And Non-Transitory Computer-Readable Storage Medium Storing Ejection State Determination Program - A simplified explanation of the abstract

This abstract first appeared for US patent application 18341817 titled 'Ejection State Determination Method, Ejection State Determination Apparatus, And Non-Transitory Computer-Readable Storage Medium Storing Ejection State Determination Program

Simplified Explanation

The ejection state determination method described in this patent application is used to determine the state of ejection of a liquid ejecting head. The liquid ejecting head consists of multiple nozzles arranged in a specific pattern.

• The method involves capturing an image of a droplet ejected from one selected nozzle at a specific timing.
• The captured image contains multi-valued data of multiple pixels.
• The first step is to obtain multiple pieces of multi-valued data by capturing the image.
• The second step is to obtain determination information from the collected multi-valued data.

Potential applications of this technology:

• This method can be applied in various industries where liquid ejecting heads are used, such as inkjet printers, 3D printers, and industrial printing systems.
• It can help in improving the accuracy and efficiency of liquid ejection processes.
• The determination information obtained can be used for quality control and troubleshooting purposes.

Problems solved by this technology:

• The method provides a reliable way to determine the ejection state of a liquid ejecting head.
• It eliminates the need for manual inspection or complex analysis methods.
• It allows for quick and automated assessment of the liquid ejection process.

Benefits of this technology:

• The method provides a simplified and efficient way to determine the ejection state of a liquid ejecting head.
• It reduces the time and effort required for inspection and analysis.
• It enables real-time monitoring and adjustment of the liquid ejection process, leading to improved quality and productivity.

Original Abstract Submitted

An ejection state determination method for determining an ejection state of a liquid ejecting head in which a plurality of nozzles for ejecting a liquid in a first direction are arranged in a second direction intersecting the first direction. The ejection state determination method includes a first obtaining step of obtaining a plurality of pieces of multi-valued data of an image including a plurality of pixels by capturing, at one timing, an image of a droplet ejected from one nozzle selected from the plurality of nozzles, and a second obtaining step of obtaining determination information from the plurality of pieces of multi-valued data.
