  • Patent number: 10618288
    Abstract: In one example, a shroud to protect a group of printheads in a printhead assembly includes a body having a first notched end where an upstream part of the body extends past a downstream part of the body and a second notched end opposite the first end where a downstream part of the body extends past an upstream part of the body. A first group of openings in the body is aligned across the upstream part of the body and a second group of openings in the body is aligned across the downstream part of the body. Each opening is to surround an exposed part of a printhead when the shroud is installed on the printhead assembly.

  • Patent number: 9975339
    Abstract: In one example, a shroud to protect a group of printheads in a printhead assembly includes openings through which the printheads are exposed when the shroud is installed on the printhead assembly and an elongated protrusion along an exterior surface next to the openings to block print media from contacting the exposed part of the printheads during printing when the shroud is installed on the printhead assembly.

  • Patent number: 8764173
    Abstract: A removable ink supply comprises an ink container including a coupler configured to removably engage a receiver of an ink supply station of an image forming apparatus. The coupler includes an end portion including an array of key holes with each key hole configured to removably receive a respective one key of an array of at least partially conductive keys of the receiver of the ink supply station. A conductive component of the coupler is positioned within the coupler and spaced apart from the end portion. The conductive component is in axial alignment with at least some of the respective key holes to be positioned for selective, removable contact with at least some of the respective keys of the receiver. An absence or a presence of removable contact between the conductive component and the key indicates an out-of-ink status of the image forming apparatus.

  • Patent number: 8714720
    Abstract: An ink container for an inkjet print head includes a substantially rigid body of polymer material, the body including a base and a side wall integrally formed with the base at a perimeter of the base, the body containing ink in a low pressure chamber, and the polymer material having moderate to high air permeability. A flexible film is sealed over the low pressure chamber, inwardly flexible in response to a decrease in pressure and ink volume in the low pressure chamber, and outwardly flexible in response to an increase in pressure and ink volume in the low pressure chamber. A metal is coated on a perimeter of the polymer body and on an outer exposed surface of the flexible film, the metal to form a metal coating configured to decrease the air permeability of the polymer body, the metal coating being formed from at least copper.

  • Patent number: 8240345
    Abstract: A fluid supply includes a container, a bag within the container and a cap. The cap provides a fluid interface in communication with an interior of the bag and a pressurization interface in communication with an interior of the container adjacent an exterior of the bag. The pressurization interface has a channel that concentrically extends about the fluid interface.

  • Patent number: 7922312
    Abstract: In one embodiment an ink pen for an inkjet printer includes: an ink filter chamber; a pressure regulator chamber downstream from the ink filter chamber along a path of ink flow through the pen; a pressure regulator in the pressure regulator chamber; a filter in the ink filter chamber; an inlet to the ink filter chamber upstream from the filter along the ink flow path; and an outlet from the ink filter chamber to the pressure regulator chamber downstream from the filter along the ink flow path such that ink flowing from the inlet to the outlet passes through the filter. In another embodiment a method implemented in an ink delivery system for an inkjet ink pen includes: chambering ink in the pen; filtering the chambered ink; and then regulating the pressure of filtered ink.

  • Patent number: 7862138
    Abstract: In one embodiment a pressure regulator for an ink pen includes: a diaphragm between a lower pressure region and a higher pressure region, the diaphragm movable toward the lower pressure region in response to an increase in a pressure difference across the diaphragm; a valve operative between an open position in which ink may flow into the lower pressure region and a closed position in which ink may not flow into the lower pressure region; a first lever rotatable on a first fulcrum in response to movement of the diaphragm toward the lower pressure region; and a second lever connected to the valve, the second lever rotatable on a second fulcrum in response to rotation of the first lever to move the valve from the closed position to an open position.

  • Patent number: 7618132
    Abstract: Damage is prevented in printing systems by allowing fluid from the printing system's fluid delivery system to expand. In one embodiment, this is accomplished by fluidly connecting a fluid expansion receptacle to the fluid delivery system. The fluid expansion receptacle provides volumetric compliance so that if printing fluid in the system expands, such as due to freezing, the fluid is able to expand into the fluid expansion receptacle and not damage the printing system.
