Abstract
An apparatus and a method retain a print unit in a dock with a retainer that is at least partially below a top of a fluid supply of the print unit.
Claims22
An apparatus comprising:
- a dock having a cavity configured to receive a print unit including a print head and fluid supply;
- and
- a print unit latch comprising:
- a cam coupled to the dock;
- a retainer configured to move between a first position in which the retainer extends over and contacts a projection extending from the print unit and extends below a top of the fluid supply to retain the print unit in the cavity of the dock and a second position in which the retainer is raised out of contact with the projection;
- a spring having a first portion coupled to the dock and a second portion coupled to the retainer, where the spring resiliently biases the retainer towards the first position;
- and
- a lever coupled to the retainer and including a cam follower in engagement with the cam, wherein rotation of the lever moves the cam follower against the cam to move the retainer between the first position and the second position, wherein the cam includes an inclined surface and wherein the cam follower slides upward along the inclined surface in response to rotation of the retainer by the lever.

A method comprising:
- inserting a print unit having a projection and a fluid supply into a cavity of a dock;
- and
- rotating a lever to move a cam follower against a cam to translate a rotational axis of the lever to horizontally and vertically move a retainer against a bias of a spring from a first position above the fluid supply in which the retainer is raised out of contact with the projection to a second position over and in contact with the projection and at least partially below a top of the fluid supply to retain the print unit in the cavity of the dock.
An apparatus comprising:

- and
- a print unit latch comprising:
- a cam coupled to the dock;
- a retainer configured to move between a first position in which the retainer extends over and contacts a projection extending from the print unit and extends below a top of the fluid supply to retain the print unit in the cavity of the dock and a second position in which the retainer is raised out of contact with the projection;
- a spring having a first portion coupled to the dock and a second portion coupled to the retainer, where the spring resiliently biases the retainer towards the first position;
- and
- a lever coupled to the retainer and including a cam follower in engagement with the cam, wherein rotation of the lever moves the cam follower against the cam to translate a first rotational axis of the lever against a bias of the spring and to move the retainer from the first position towards the second position.
