Abstract
In an example, a method for determining an issue in an inkjet nozzle includes providing an initial fire pulse for firing a nozzle, and receiving the initial fire pulse as a delayed fire pulse at a primitive of the nozzle. The method includes firing the nozzle with the delayed fire pulse, and determining a first time instant following the delayed fire pulse for taking a first impedance measurement across the nozzle.
