Abstract
A fluid ejecting apparatus for ejecting a fluid includes a recording head and a capping device. The recording head includes a storage portion and a plurality of ejection nozzles. The capping device comes into contact with a discharge surface of the fluid in the recording head and receives the fluid discharged through the nozzles. The recording head capping device includes a cap-side channel and a passing portion. The cap-side channel faces the nozzles when the recording head capping device is in contact with the discharge surface. The passing portion creates negative pressure in the nozzles by passing a material in the cap-side channel. The cap-side channel includes a high flow rate section and a low flow rate section.
