Abstract
A recording apparatus of the present invention includes: a droplet ejection head including an inflow passage, a common fluid passage, and a plurality of individual fluid passages each extending to an ejection opening; a supply mechanism capable of forcedly supplying a fluid to the inflow passage; a wiper made of an elastic material; and a moving mechanism which moves the wiper. The fluid forcedly supplied to the inflow passage and discharged from each ejection opening does not drop from the ejection face, and at least a predetermined amount of the fluid discharged from each ejection opening is retained on the ejection face when the wiper traverses the relevant ejection opening.
Claims8
A recording apparatus, comprising:
- a droplet ejection head extending in one direction, the droplet ejection head including an inflow passage having an inflow port through which a fluid flows into the inflow passage, a common fluid passage connected to the inflow passage, and a plurality of individual fluid passages each extending from an outlet of the common fluid passage to a corresponding ejection opening of a plurality of ejection openings formed on an ejection face via a pressure chamber;
- a supply mechanism capable of forcibly supplying the fluid to the inflow passage;
- a wiper formed of an elastic material;
- a moving mechanism configured to move the wiper in the one direction while contacting the wiper to the ejection face;
- and
- a controller configured to control the supply mechanism and the moving mechanism,
- wherein the controller is configured to control the supply mechanism and the moving mechanism so that:
- the fluid forcibly supplied to the inflow passage and discharged from each ejection opening does not drop from the ejection face,
- at least a predetermined amount of the fluid discharged from each of the ejection openings is retained on the ejection face, and
- a negative pressure acts on a relevant ejection opening when the wiper traverses the relevant ejection opening, wherein the at least a predetermined amount of fluid retained on the ejection face is sucked into the relevant ejection opening by the negative pressure.
