A method for an inkjet printhead assembly (300) having ink ejection elements (416) energizable by an electrical pulse to improve inkjet firing reliability by using high energy during the droplet ejection for nozzles that have been inactive for a period of time or are printing at low image density. The invention provides a method of controlling an inkjet printhead assembly (300), including providing a printhead assembly (300) having ink ejection elements (416) energizable by an electrical pulse having a first predetermined energy; monitoring each printhead assembly (300) individually to determine the print density of the printhead assembly (300), or elapsed time since each ink ejection element (416) on the printhead assembly (300) has been fired; comparing the print density of the printhead assembly (300) with a predetermined print density, or comparing the elapsed time for each ink ejection element (416) on the printhead assembly (300) with a predetermined maximum amount of time for the printhead assembly (300); and initiating high energy spitting over the spittoon (250) for the printhead assembly (300) if the print density is below the predetermined print density, or the predetermined maximum amount of time has been exceeded for one of the ink ejection elements (416) on the printhead assembly (300).
