  • Patent number: 7244013
    Abstract: A printer includes a cleaning mechanism that reliably performs an operation of cleaning a liquid ejecting head with a small amount of driving energy. The cleaning mechanism includes a cap manufactured by coinjection molding of a core part and an elastic part. The cap includes a bottom surface, an outer wall, and a partition wall dividing a cap inner space surrounded by the outer wall into two. A ratio of the elastic part in the partition wall is higher than that in the outer wall. With this structure, the partition wall is more elastically deformable than the outer wall. When the cap comes into contact with a nozzle surface of a recording head and covers nozzle rows, the outer wall comes into contact with the nozzle surface with a larger stress compared with the partition wall, and seals chambers where the nozzle rows on the nozzle surface are exposed.

  • Patent number: 7237869
    Abstract: An inkjet printer includes a conveyance unit, a recording head, a sealing unit, and a carrier unit. The conveyance unit conveys a recording medium in a conveyance direction. The recording head includes plural recording portions. Each recording portion has plural ejection ports for ejecting ink. The recording portions partially overlap each other if viewed in the conveyance direction, when the recording head is located at a recording position where the recording head performs record with respect to the recording medium. The sealing unit is disposed in a region outside the conveyance unit. The sealing unit includes plural sealing portions each of which seals the ejection ports of each recording portion. The sealing portions are arranged in the conveyance direction. The carrier unit carries the recording head in a carrying direction between a sealing position where each sealing portion faces the ejection ports of each recording portion and the recording position.

  • Patent number: 7237868
    Abstract: A capping device and method for a print head for an inkjet printer are disclosed. The capping device has a head cap to seal the print head during the printing standby mode. The head cap has a through hole to allow a sealed portion formed between the head cap and the print head to fluidly communicate outside of the head cap. The through hole is respectively disposed at an inner wall and outer wall of the head cap. Due to the through hole, an air path is formed in the head cap to allow a sealed portion between the print head and the head cap to fluidly communicate with the outside. Even if the air in the sealed portion is heated and expanded, the pressure therein does not increase.

  • Patent number: 7232204
    Abstract: The cleaning process best suited to the condition of an inkjet printer is selected and run, thereby removing nozzle clogging without wastefully consuming ink. The first time a cleaning switch 7 is operated a CL1 cleaning process is run. If the cleaning switch 7 is pressed a second time and the print pass count is less than e.g., 400, a CL2 cleaning process that uses more ink than the CL1 process is used to clean the recording head, but if the print pass count is 400 or more, the CL1 cleaning process is used. If the print pass count is less than 400 the third time the switch is operated, the CL2 cleaning process is used, but the CL1 cleaning process is used if the print pass count is 400 or more. If the cleaning switch 7 is operated four or more times and the print pass count is less than 400, a YCL cleaning process that consumes substantially no ink is used to clean the recording head, but if the print pass count is 400 or more, the CL1 cleaning process is used.

  • Patent number: 7213904
    Abstract: A discharge recovery device and an ink-jet recording apparatus incorporating the same. The discharge recovery device includes a wiper reciprocating to wipe a discharging surface of a recording head. The wiper touches a pivotable wiper cleaner while moving in a forward direction, and is thereby cleaned of ink. The wiper cleaner is fixed and rubs against the wiper when the wiper moves forward. A cleaner holder also covers the wiper to prevent ink scatter when the wiper in the forward direction. As the wiper moves in a backward direction, the wiper cleaner is pivoted out of contact with the wiper via a retracting device. This reliably prevents ink from scattering during the backward movement of the wiper without reducing cleaning performance of the wiper cleaner.
