  • Patent number: 8721041
    Abstract: An ink collecting system has been developed to direct ink purged from a printhead positioned above an ink collecting tray along a stepped flow path into the ink collecting tray. The stepped flow path enables the purged ink to flow from a faceplate on the jet stack, around a junction, onto a lower surface of the jet stack, and to a curved lower flange of a reservoir housing, which directs the ink away from the faceplate before the ink drops into the ink collecting tray for disposal or reuse.

  • Patent number: 8556398
    Abstract: A method for operating a printer having multiple printheads includes activating a heater that is operatively connected to a printhead that ejects ink having a single color in response to receiving a print job. The printer detects the presence of colors other than the single color in image data received in the print job, and activates heaters operatively coupled to printheads that eject ink drops that correspond to the detected colors.

  • Patent number: 8454144
    Abstract: A reservoir is provided for a printhead in an ink jet printing machine, the printhead having at least one printhead inlet at a rear face thereof for flow of ink from the reservoir into the printhead. The reservoir comprises a perimeter wall sealably mounted to the rear face of the printhead and defining a chamber in communication with the printhead inlet. The chamber is open at one face and the reservoir includes a resilient flexible membrane attached to the perimeter wall and covering the one face. An inlet is provided in communication with the chamber for passage of ink into the chamber. The resilient flexible membrane has an initial relaxed condition in a first state in which the reservoir is substantially full of ink, and a flexed condition in which the membrane is collapsed into the chamber.

  • Patent number: 8256871
    Abstract: An inkjet printhead has been developed that includes an ink reservoir vent, which prevents ink from exiting the ink reservoir through the vent. The inkjet printhead includes a reservoir, an ink inlet, a vent opening, and a vent member. The reservoir contains a supply of ink and an air space above the supply of ink. The vent member extends from the vent opening and includes a first vent member opening positioned in an air space outside of the reservoir, a second vent member opening positioned in the air space above the supply of ink, and a vent channel configured to couple fluidly the first vent member opening to the second vent member opening. The second vent member opening is positioned within the reservoir to enable the second vent member opening to remain within the air space above the supply of ink regardless of a printhead orientation.

  • Patent number: 8226187
    Abstract: An ink level control system includes a first dividing wall that divides a reservoir of a printhead into a first chamber and a second chamber. The first and the second chambers are each connected to the ink passages of the inkjet stack by an ink port. The first dividing wall includes an opening that connects the first chamber and the second chamber to enable ink to pass therebetween. The opening is located a predetermined distance above the bottom surface of the reservoir. An ink diverter is associated with the inlet opening that directs ink received through the inlet opening to one of the first and the second chambers in response to the reservoir being tilted in a first direction, and directs ink to the other of the first and the second chambers in response to the reservoir being tilted in a second direction.
