To provide the maintenance method of a fluid ejection device which reduces occurrence of problems due to a fluid, by removing the fluid adhering to a seal surface, and also to provide the fluid ejection device.
The fluid ejection device includes: an ejection head having an ejection surface in which an ejection port for ejecting the fluid is formed; and a maintenance part having a cap member coming into contact with the ejection surface and a wiping member wiping the ejection surface. The device adopts a method including: a first process for sequentially performing a suction operation S45 for bringing the cap member into contact with the ejection surface, to suck the fluid in space formed by the ejection surface and the cap member, a separation operation S46 for separating the cap member from the ejection surface, and a wiping operation S47 for wiping the ejection surface by the wiping member; and a second process for sequentially performing a transfer operation S50 for bringing the cap member into contact with the ejection surface, to transfer the fluid adhering to the cap member to the ejection surface, a separation operation S51, and a wiping operation S52.
