Abstract: In example implementations, a powder level sensor is provided. The powder level sensor includes a capacitive sensor, a processor, and a cleaning mechanism. The processor is communicatively coupled to the capacitive sensor. The processor interprets a measurement of the capacitive sensor to detect a layer of residual build material on a surface of the powder level sensor. The cleaning mechanism may be communicatively coupled to the processor. The processor activates the cleaning mechanism to remove the layer of residual build material on the surface of the powder level sensor.

Abstract: Examples of a mounting device and method are disclosed herein. An example of the mounting device includes a carriage to hold a printhead assembly and an interconnect assembly to supply printing composition to the printhead assembly. The mounting device also includes a first latching assembly having an engaged condition to lock the interconnect assembly to a manifold of the printhead assembly and a disengaged condition to unlock the interconnect assembly from the manifold of the printhead assembly. The mounting device additionally includes a second latching assembly having an engaged condition to lock the printhead assembly to the carriage and a disengaged condition to unlock the printhead assembly from the carriage. In this example of the mounting device, the second latching assembly cannot be moved from the engaged condition to the disengaged condition unless the first latching assembly is in the disengaged condition.
