Abstract
An inkjet printhead has nozzles and respective heater elements. A print engine controller actuates the heater elements to eject ink through the corresponding nozzle. During use, the print engine controller actuates each of the heater elements at least once every decap time. The decap time is a predetermined time period in which the viscosity of the ejectable liquid at the nozzle increases to a threshold, at which ejection fails and the nozzle clogs.
