Abstract: In some examples, a controller is to receive sensor data from a sensor associated with a fluid delivery system that delivers fluid from a fluid reservoir to a fluid conduit, determine, based on the sensor data, presence or integrity of a gas purger that is to be fluidically coupled to the fluid conduit, and issue an alert to indicate a gas purger anomaly condition based on the determining.

Abstract: Aspects of the disclosure provide an electronic device comprising a controller. The controller to determine a volume of print fluid in a first tank of the electronic device, monitor current printing conditions of the electronic device disposing print fluid on a substrate, determine, based on the volume of print fluid and the current printing conditions, whether an adverse printing condition exists, responsive to the volume of print fluid being less than a threshold and the adverse printing condition not existing, control a pump to refill the first tank from a second tank at a flow rate determined at least partially according to the determined volume, and responsive to the volume of print fluid being less than the threshold and the adverse printing condition existing, control the pump to refill the first tank from the second tank at a default flow rate determined independent of the determined volume.
