Description

  The present invention relates to a liquid ejecting apparatus that ejects liquid from a liquid ejecting head mounted on a carriage toward a recording medium.

Inkjet printers are widely known as liquid ejecting apparatuses that eject liquid from a liquid ejecting head onto a recording medium.
The ink jet printer includes a carriage and a recording head mounted on the carriage. While the carriage is scanned and moved with respect to the recording paper (recording medium), ink (liquid) is ejected from the nozzles formed on the recording head to perform printing on the recording paper.

Some inkjet printers have an ink cartridge for supplying ink to a recording head mounted on a carriage (on-carriage type). The ink cartridge is detachably attached to the carriage.
In an on-carriage type ink jet printer, the ink capacity of the ink cartridge is limited. When a relatively large amount of printing is to be executed, the ink cartridge needs to be frequently replaced, increasing the running cost.

  An apparatus has been proposed in which a large ink tank is disposed outside an ink jet printer and ink is supplied from the ink tank toward a carriage. An attachment is mounted on the carriage in place of the ink cartridge. Ink is supplied from the ink tank to the attachment through a tube. Thereby, it can print in large quantities (refer patent document 1).
