Patent number: 8857949Abstract: A liquid ejecting apparatus includes a liquid ejecting head having a nozzle formation surface with a nozzle that discharges a liquid. A cleaning member wipes the nozzle formation surface to remove liquid that has adhered thereto. An absorption member of a porous material deforms under pressure and includes an absorption surface that contacts the cleaning member to absorb liquid that has adhered thereto. A pressure member moves between a pressure position, in which the pressure member applies pressure to the absorption surface of the absorption member, and a non-pressure position, in which the pressure member does not apply pressure to the absorption surface. A movement mechanism moves the pressure member from the non-pressure position to the pressure position to cause the absorption member to deform, thereby dispersing the liquid absorbed by the absorption member from the cleaning member via the absorption surface into the interior of the absorption member.Type: GrantFiled: March 17, 2010Date of Patent: October 14, 2014Assignee: Seiko Epson CorporationInventors: Takeo Seino, Taisuke Yamamoto, Shuhei Harada, Naoyoshi Hashimoto, Yoshihiro Koizumi
