Abstract
Embodiments of the present disclosure include systems and methods of handling ink using a movable spittoon platform. A frame defines at least a reservoir portion and a side wall protrusion adjacent the reservoir portion. A shuttle includes a platform slidably movable between a first position, in which the platform is biased to extend outwardly from an end portion of the shuttle, and a second position, in which the platform becomes retracted relative to the end portion of the shuttle. The shuttle is slidably movable relative to the frame toward the spittoon portion wherein, upon releasable contact of the platform against the protrusion, the platform moves from the first portion into the second portion to scrape ink off the platform into the reservoir portion below the shuttle.
Claims21
A printer service station comprising:
- a frame including a reservoir portion and a stationary protrusion adjacent the reservoir portion;
- and
- a shuttle disposed vertically above the frame and slidably movable relative to the frame along a first orientation between a first shuttle position and a second shuttle position spaced apart, along a length of the frame, from the first shuttle position, wherein the shuttle comprises an end portion including a stationary element and a spittoon platform, the spittoon platform being slidably movable along the first orientation between a first platform position extending outwardly from the end portion and a second platform position retracted relative to the end portion, with the platform biased in the first platform position,
- wherein in the first shuttle position, the platform is spaced apart from the stationary protrusion and is in the first platform position and wherein upon movement of the shuttle into the second shuttle position, the platform releasably contacts the stationary protrusion to cause the platform to move from the first platform position into the second platform position to cause scraping movement of the platform relative to the stationary element of the shuttle.

A printer comprising:
- a service station comprising:
- a frame including a reservoir portion and a stationary protrusion adjacent the reservoir portion;
- and
- a shuttle disposed vertically above and slidably movable relative to the frame in a first orientation between a first shuttle position and a second shuttle position spaced apart, along a length of the frame, from the first shuttle position, wherein the shuttle comprises an end portion and a spittoon platform, the spittoon platform being slidably movable between a first platform position extending outwardly from the end portion and a second platform position retracted relative to the end portion, with the platform biased in the first position,
- wherein in the first shuttle position, the platform is spaced apart from the stationary protrusion and is in the first platform position, and wherein upon movement of the shuttle into the second shuttle position, the platform releasably contacts the stationary protrusion to cause the platform to move from the first platform position into the second platform position to cause scraping movement of the platform relative to the end portion of the shuttle;
- and
- a printhead assembly selectably movable along a second orientation, generally perpendicular to the first orientation, to a service position over the service station at which the printhead assembly is positioned to perform spitting operations over the spittoon platform of the service station.

A printer service station comprising:
- a frame including a reservoir portion and a stationary protrusion adjacent the reservoir portion;
- and
- a shuttle disposed vertically above the frame and slidably movable relative to the frame along a first orientation between a first shuttle position and a second shuttle position spaced apart, along a length of the frame, from the first shuttle position, wherein the shuttle comprises an end portion including a stationary element and a spittoon platform, the spittoon platform being slidably movable along the first orientation between a first platform position extending outwardly from the end portion and a second platform position retracted relative to the end portion, with the platform biased in the first platform position,
- wherein in the first shuttle position, the platform is spaced apart from the stationary protrusion and is in the first platform position and wherein upon movement of the shuttle into the second shuttle position, an end portion of the platform releasably contacts the stationary protrusion to cause the platform to move from the first platform position into the second platform position to cause scraping movement of the platform relative to the stationary element of the shuttle,
- wherein the first shuttle position corresponds to a spitting location and when the platform is in the first platform position, the stationary element of the shuttle is interposed between the spitting location and a spit-receiving surface of the spittoon platform.
