Definitions

  • the present disclosure relates to an inkjet printer, and more particularly, to an device for cleaning a printing head of an inkjet printer.
  • An inkjet printer is an apparatus for printing images of a predetermined color on the surface of a print medium by ejecting small droplets of print ink onto desired locations of the print medium.
  • the inkjet printer includes a carrier moving back and forth in a predetermined direction, an ink cartridge mounted on the carrier and storing ink, and a printing head provided on the ink cartridge to eject ink.
  • the printing head includes a plurality of nozzles for ejecting ink toward the surface of the print medium.
  • ink ejected from the plurality of nozzles or foreign materials such as dust gather on the surface of the printing head.
  • the ink coagulates and blocks the nozzles or the foreign materials block the nozzles such that ink is not ejected or ejected in a wrong direction, resulting in poor print quality.
  • wiping blades move back and forth periodically during a printing operation or after a printing operation to clean the surface of the printing head, thereby removing ink or foreign materials around the nozzles.
  • ink is gathered on the wiping blades as they clean the printing head, and the ink gathered on the wiping blades coagulates to thereby damage the surface of the printing head or prevent a process of cleaning the surface of the printing head from being smoothly performed. Furthermore, foreign materials such as dust gather on the wiping blades, and the foreign materials damage or contaminate the print head.
  • a printing head cleaning device for an inkjet printer having a structure capable of cleanly wiping off ink or foreign materials that have gathered on a wiping blade to prevent a printing head of the inkjet printer from being damaged and to more effectively clean the printing head.
