INKJET PRINT HEAD MAINTENANCE STRUCTURE USING INK FEED VALVE

摘要

PURPOSE: An inkjet print head maintenance structure is provided to allow print head to smoothly perform its function by removing air bubble remaining in the chamber of print head and preventing clogging of nozzle. CONSTITUTION: In an inkjet print head where ink feeding is performed directly through an ink feed channel(110), from an ink cartridge(100) to a chamber(120) of the inkjet print head, an electrically controllable valve(111) is arranged at the ink feed channel, such that the leakage of ink remaining in the chamber is prevented by shutting off the valve during the use of suction device or maintenance work performed due to capping operation.
