    Abstract: An example printhead assembly includes a housing, nozzles and a collapsible container within the housing to supply ink to the nozzles. The collapsible container includes a top wall, a bottom wall, first and second side walls that form an interior and a spring assembly within the interior. The first flexible wall includes a first amount of excess material. The second flexible wall includes a second amount of excess material less than the first amount of excess material such that motion of the first flexible wall of the collapsible container is constrained against movement to a lesser extent as compared to the second flexible wall. The first flexible wall faces the sensor. A sensor assembly is coupled to the housing and includes a sensor to provide a sensor signal indicating the amount of ink within the collapsible container.

    Abstract: A cassette may include a substrate, a die coupled to the substrate, and an electrical interconnection pad layout formed on a first side of the substrate. The electrical interconnection pad layout may include a first row of interconnect pads including at least one interconnect pad. Each interconnect pad of the first row of interconnect pads may be electrically coupled to one of a first set of vias. The electrical interconnection pad layout may also include a second row of interconnection pads including at least one interconnect pad. Each interconnect pad of the second row of interconnect pads being electrically coupled to one of a second set of vias. The second set of vias electrically coupled to the second row of interconnect pads are offset relative to an alignment of the interconnect pads of the first and second rows.

    Abstract: A liquid dispenser cassette includes a frame, dispense head assemblies, and a one-piece integrated slot extender. The frame defines openings. The dispense head assemblies are mounted on the frame. The dispense head assemblies include dispense head dies at least partially exposed through the corresponding openings. The dispense head dies defines top slots. The slot extender is mounted on the dispense head assemblies. The slot extender has reservoirs defining drain openings mated to the corresponding top slots.
