Claims15
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.
