Benefits of technology

The patent text discusses the need for a new cleaning liquid in inkjet recording that has high cleaning performance and does not cause problems when stored before filling the inkjet ink. The existing cleaning liquid has limitations such as low filling properties, erosion of metal parts, and swelling adhesive agents. The new cleaning filling liquid provides a solution to these issues and ensures a stable inkjet printing process.

Problems solved by technology

In addition, because the inkjet ink tends to have a high solid content, it becomes more difficult to clean up the liquid flow channel, particularly inside of the nozzle, so as to prevent defects in the recycled cartridge.
Therefore, conventional cleaning liquid has a lack of cleaning property.
Even if the conventional cleaning liquid has enough cleaning property, the cleaning liquid has disadvantages such as low filling property of the inkjet ink, which causes jetting defect.
In addition, the cleaning liquied swells adhesive agent in the head to decrease strength of the head, or the cleaning liquid erodes metal portions of the liquid flow channel, when it is storaged before filling the inkjet ink, which may decrease jetting stability.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This patent application is based on and claims priority pursuant to 35 U.S.C. §119 to Japanese Patent Application No. 2012-019920, filed on Feb. 1, 2012, in the Japan Patent Office, the entire disclosure of which is hereby incorporated by reference herein.FIELD OF THE INVENTION[0002]The present invention relates to a cleaning filling liquid, a cartridge, a cleaning filling method, and an inkjet recording device.BACKGROUND OF THE INVENTION[0003]Ink cartridge has a liquid flow channel such as an ink flow member between ink storage and ink outlet. When the ink cartridge is recycled, the liquid flow channel must be cleaned to assure performance of the recycled cartridge.[0004]An inkjet head is composed of a nozzle having an orifice, wherein the diameter of the orifice is not more than 50 μm, a pressure generator, a liquid container, a filter, and so on. Each component is processed precisely and therefore each inkjet head has multiple inkjet n...
