Problems solved by technology

However, since the rubber wiper cannot reach the stepped portion, the rubber wiper cannot catch the liquid staying at the stepped portion.
As a result, the liquid that has not been captured and stayed in the step portion solidifies and gradually accumulates, which may prevent the cap from coming into contact with the nozzle forming surface when the liquid is sucked from the nozzle, for example.
Or, the accumulated and solidified liquid may fall on the medium, resulting in the deterioration of the quality of the image formed on the medium.

Abstract

A liquid ejecting apparatus includes a liquid ejecting head on which a liquid ejecting nozzle is provided; and a wiping section which wipes the liquid ejecting head by relative moving a liquid absorption body which absorbs the liquid while abutting the liquid absorption body to the liquid ejecting head, wherein the liquid ejecting head has a surface constituted of first region surface on which the nozzle is formed and a second region surface which is continuous to the first region surface with a step, as a wiping surface which is wiped by the wiping section, and wherein on the wiping surface, the second region surface is a surface having lower liquid-repellency than the first region surface with respect to the liquid.

Description

technical field [0001] The present invention relates to a liquid ejecting device, and in particular, to a technique for wiping liquid adhered to a liquid ejecting head. Background technique [0002] Conventionally, as a liquid ejecting device, there is known an inkjet type printer that ejects a liquid onto a medium such as paper from nozzles formed in a liquid ejecting head to form an image. Such printers are generally provided with a maintenance device for maintaining the ejection characteristics of the liquid ejected from the nozzles. [0003] For example, as such a maintenance device, there is provided a wiping unit that wipes off liquid adhering to the nozzle forming surface on which the nozzles are formed in the liquid ejecting head. The wiping part usually has a rubber wiper made of a rubber material such as an elastic body, and the rubber wiper is moved while the rubber wiper is brought into contact with the nozzle forming surface of the liquid ejection head, whereby...
