  • Patent number: 10549937
    Abstract: Examples disclosed herein relate to a device including a separator. Examples include a first separator having a surface to contact a medium and is coupled to a first spring. In examples, the first separator has a first centerline in a direction perpendicular to a medium travel direction. Examples include a second separator having a surface to contact a medium and is coupled to a second spring. In examples, the second separator has a second centerline disposed substantially parallel to the first centerline. Examples include a roller to contact the medium to move the medium along the medium travel direction. In examples, the first spring and second spring bias the first separator and second separator towards the roller, respectively. In examples, a force applied by the first separator to the medium is independent of a force applied to the medium by the second separator.

  • Patent number: 10525737
    Abstract: In one example, a system for a partially dried inkjet media conditioner includes a partially dried Inkjet media conditioner, including: a first connector to couple a first end of the conditioner to a printing device, a second connector to couple a second end of the conditioner to a finishing device, and a constrained path extending through the conditioner to receive partially dried inkjet media from the printing device and provide the partially dried Inkjet media to the finishing device.

  • Patent number: 10434785
    Abstract: In an example implementation, a fluid supply assembly includes a printhead assembly and a carriage comprising a quick-release, hand-operable attachment mechanism to removably attach the printhead assembly to the carriage. A fluid conduit interconnect is rigidly attached to the printhead assembly by a tool-operable fastener. The fluid conduit interconnect is to connect to a fluid conduit to communicate printing fluid from an off-axis printing fluid supply to the printhead assembly.

  • Patent number: 10414163
    Abstract: In an example implementation, a fluid supply assembly includes a printhead assembly and a fluid conduit interconnect to connect to a fluid conduit to communicate printing fluid from an off-axis printing fluid supply through the fluid conduit interconnect to the printhead assembly. The fluid supply assembly includes a carriage with a dual attachment mechanism to simultaneously attach the printhead assembly to the fluid conduit interconnect and to the carriage by a single user action.

  • Patent number: 10195862
    Abstract: An off-axis printhead assembly includes a printhead body that has an engagement element removably attachable to an attachment mechanism of a carriage of a printing system, the attachment mechanism of the carriage removably attachable to an on-axis printhead assembly. A fluid conduit interconnect is removably attached to the printhead body, the fluid conduit interconnect to connect to a fluid conduit to communicate printing fluid from at least one off-axis printing fluid supply through the fluid conduit interconnect to the printhead body.

  • Publication number: 20180311965
    Abstract: In an example implementation, a fluid supply assembly includes a printhead assembly (PHA) attachable to a printing system carriage. A first fluid conduit permanently affixed to the PHA, and a second fluid conduit is attachable to the first fluid conduit by a fluid conduit coupling to enable fluid to flow from an off-axis fluid supply to the PHA.
