A service station device in an inkjet printer head includes a cap portion which moves together with a case under guide of the case by a pressure force of a carriage moving to a service area for performing next printing and is then ascended to tightly close a nozzle of a head; a wiper portion which moves and is ascended along with the case under the guide of the case, upon movement of the cap portion, to stand by a cleaning state, and upon printing operation, which moves and descends only the cap portion to a printing area and at the same time cleans a surface of the nozzle; a locking portion integrated with the wiper portion as one unit, which moves together with the wiper portion, to thereby be locked to the case during a standby state, and upon the printing operation, returns to an original state with the wiper portion by releasing the standby state by means of the carriage being continuously moved; and an elastic portion coupled to the case and to the locking portion, which is elastically extended to lock the locking portion to the case, upon movement of the locking portion, and at the same time, releases the locking state by the carriage to return the locking portion to the original state.
The present invention relates to a wiping apparatus for an ink jet printer, which apparatus prevents the area surrounding the wiping apparatus from being contaminated by ink. The wiping apparatus reduces the amount of ink splashed on the surroundings when a wiper is out of the lower part of a cartridge. The apparatus comprises a housing having an upper part which is open, a cartridge which can be moved from one side to another side in an upper part of the housing, a nozzle for ejecting ink and provided on one side of the cartridge, a wiper installed on an upper part of the housing and made of an elastic material for cleaning the nozzle, a holding unit for holding the wiper and rotatable in a direction of the nozzle when the wiper is bent in one direction for cleaning the nozzle, and an operation unit which operates the holding unit and is provided to move together with the cartridge.
A printer with print head cleaning function is provided. The printer includes a housing, a round shaft, a carrier and a clean housing. The round shaft is disposed in the housing. The carrier is reciprocally disposed on the round shaft. The carrier is used for carrying one cartridge of the printer. The clean housing is equipped with a cleaner, which is used for cleaning one print head of the cartridge. When the carrier moves upward or downward, the carrier mechanically drives the clean housing to move upward or downward to maintain a fixed interference distance between the cleaner and the print head for enabling the cleaner to clean the print head and maintain the printing quality.
A capping system has a cap for capping an ink jet print head, and a supporting structure for mechanically engaging and disengaging the cap with the ink jet print head. The cap has a vent. When the supporting structure engages the cap with the ink jet print head, the cap covers the ink jet print head to cap the ink jet print head. The vent in the cap ensures that the pressure inside the volume of the cap equalizes with the pressure outside the volume of the cap. This prevents overpressure within the cap.
A printing device has a motor that drives an ink jet print head back and forth along a print track. A service station is installed on one end of the print track, and has a first track, a second track, a slot track, and a wipe sled. The wipe sled slides inside a housing of the service station along the first track, in parallel with the print track. The slot track, which is part of the wipe sled, in diagonal to the print track. The second track, mounted on the housing, is perpendicular to print track. A wiper is mounted on both the slot track and the second track. The relative movement of the slot track with the second track as the wipe sled is pushed backwards forces the wiper into a working position.
The invention relates to a service station for an inkjet printer. The service station includes at least one cap for capping a printhead which is mounted on an inkjet carriage of the inkjet printer. The service station also includes at least one wiper arranged to wipe said printhead carried by the inkjet carriage. The wiper is arranged to move towards and away from the printhead in response to movement of the inkjet carriage so as to enable the printhead to be wiped of any residual ink.
