One or more techniques and/or systems are provided for evaluating dispenser functionality of a dispenser for dispensing a material. In an example, a non-loaded electrical characteristic and/or a loaded electrical characteristic of the dispenser may be measured and evaluated to determine whether to perform a dispense event. In another example, current measurements, such as peak current, may be measured during a dispense event. The current measurements may be evaluated to determine whether a problem exists, such as a mechanical stall, a gear train problem, an actuator problem, a pump problem (e.g., a clogged pump), a mechanical impedance, and/or other issue. Such information may be collected, stored as historical data, and/or used to determine whether to perform subsequent dispense events. |
