Title: Innovations of Sonoko Egawa

Introduction

Sonoko Egawa is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of inkjet technology, holding three patents that showcase his innovative spirit and technical expertise.

Latest Patents

One of his latest patents is an ink jet recording apparatus. This apparatus includes a cap, a control unit, and a recording unit featuring nozzle arrays. Each nozzle array consists of multiple nozzles that eject ink during image recording operations. The cap is designed to receive ink that is preliminarily ejected from the recording unit. The control unit manages the ejection operation, ensuring that the amount of ink ejected from a first nozzle group during a preliminary ejection is smaller than that from a second nozzle group in a subsequent preliminary ejection. This is particularly useful when the recording command specifies using the second nozzle group without involving the first. Another significant patent is related to an inkjet printing apparatus, control method, and storage medium. This invention estimates the amount of ink in a cap at the end of printing initiated by a print command. It determines whether an open suction action should be performed based on the estimated post-printing ink amount, thereby preventing ink spillover and reducing downtime.
