Liquid Ejection Apparatus

摘要

A liquid ejection apparatus comprises a liquid ejection head, a nozzle cap, and a suction pump. The liquid ejection head includes first nozzles, second nozzles, and an ejection surface in which the first nozzles and the second nozzles are formed. The nozzle cap includes a first cap section for covering the first nozzles, a second cap section for covering the second nozzles, a communication section connected with the first cap section and the second cap section, a suction port for being connected with the suction pump, and an atmosphere communication port for communication with atmosphere. At least one of the suction port and the atmosphere communication port is provided at non-connection end portions which are end portions in the one direction of the first cap section and the second cap section and are not connected with the communication section.

1. A liquid ejection apparatus comprising:
a liquid ejection head including first nozzles which are lined up in predetermined one direction, second nozzles which are lined up in the one direction and positionally deviated from the first nozzles in a direction orthogonal to the one direction, and an ejection surface in which the first nozzles and the second nozzles are formed; a nozzle cap configured to contact with and move away from the ejection surface, and cover the first nozzles and the second nozzles when contacting with the ejection surface; a moving device configured to cause the nozzle cap to contact with or move away from the ejection surface by moving at least one of the liquid ejection head and the nozzle cap; and a suction pump connected with the nozzle cap, wherein, the nozzle cap includes: a first cap section for covering the first nozzles; a second cap section for covering the second nozzles; a communication section connected with the first cap section and the second cap section; a suction port for being connected with the suction pump; and an atmosphere communication port for communication with atmosphere, at least one of the suction port and the atmosphere communication port is provided at non-connection end portions which are end portions in the one direction of the first cap section and the second cap section and are not connected with the communication section.
