Description

  The present invention relates to a liquid ejecting apparatus such as an ink jet printer.

  Conventionally, an ink jet printer (hereinafter referred to as “printer”) is known as a liquid ejecting apparatus that ejects liquid onto a target. This printer includes an ink cartridge that stores ink, and a recording head (liquid ejecting head) that is mounted on a carriage and is supplied with ink (liquid) from the ink cartridge via an ink supply path. In such a printer, the ink pack in the ink cartridge is pressurized with pressurized air fed from a pressure pump, and the ink is pressure-fed to the recording head side through the ink supply path, and the nozzle of the recording head There is a so-called off-carriage type in which printing is performed by ejecting ink toward a recording medium (for example, Patent Document 1).

Further, in the printer as described above, in order to reduce ink ejection failure, cleaning that ejects thickened ink or the like from nozzles that eject ink is appropriately performed. In this cleaning, after the nozzle forming surface on which the nozzle is formed is sealed with a cap, the space (inside the cap) that is airtight between the nozzle forming surface and the cap is sucked with a suction pump to make a negative pressure. Thus, the ink having increased viscosity in the nozzle is discharged using this negative pressure. In such cleaning, the ink discharged from the nozzle is sucked by the suction pump and collected in the collection container. As a printer provided with such a suction pump and a collection container, what was described in patent documents 2 is known conventionally.
