Abstract: One example of a fluidic die includes a power supply node, a plurality of fluidic actuators, a plurality of discharge circuits, and a single discharge enable signal path. The plurality of fluidic actuators are electrically coupled to the power supply node. The plurality of discharge circuits are electrically coupled to the power supply node. The single discharge enable signal path is electrically coupled to each discharge circuit of the plurality of discharge circuits to enable each discharge circuit of the plurality of discharge circuits in parallel.

Abstract: An example fluid ejection device comprises a plurality of distinct fluid channels. Each fluid channel comprises a distinct fluid inlet to the ejection device. A subset of the plurality of distinct fluid channels comprises fluid recirculating fluid channels, and the remaining fluid channels comprising non-recirculating fluid channels.

Abstract: In some examples, a controller to receives, from a strain sensor in a fluidic die component, measured strain data, and detects a change in direction of the fluidic die component based on the measured strain data.

Abstract: In one example, a warming system for a region of multiple ejector elements on an inkjet printhead includes a warming circuit having a heating element distinct from any of the ejector elements and a controller programmed to selectively energize the heating element only upon determining none of the ejector elements in the region is active.

Abstract: A replaceable print apparatus component includes a print material reservoir, a print material within the reservoir having a first print material level, and a logic circuitry package including an interface and a logic circuit. The logic circuit may receive, via the interface, a first calibration parameter and receive, via the interface, a first request corresponding to a first sensor ID associated with a second print material level above the first print material level. The logic circuit may transmit, via the interface, a first digital value in response to the first request and receive, via the interface, a second calibration parameter less than the first calibration parameter. The logic circuit may receive, via the interface, a second request corresponding to the first sensor ID, and transmit, via the interface, a second digital value in response to the second request. The second digital value is less than the first digital value.
