Abstract: A fluid infusion device and related operating methods are presented here. An exemplary embodiment of the device includes a drive motor assembly, a force sensor associated with the drive motor assembly, and a reservoir cavity that accommodates fluid reservoirs. An exemplary operating method for the device obtains force measurements for a reservoir seating action of the drive motor assembly, where the force measurements indicate measures of force imparted to the force sensor during the reservoir seating action. The method continues by determining that a vent in the reservoir cavity is blocked, based on an analysis of the force measurements, and by initiating corrective action for the fluid infusion device in response to determining that the vent in the reservoir cavity is blocked.
