Abstract
An inkjet printing system includes a drop ejector array module having a temperature sensor and a logic circuit for sequentially selecting one or more drop ejectors in the array. The system also includes an image data source for providing an image data signal, a memory for storing a temperature correction factor, and a memory for storing at least one drop ejector correction factor. The system includes a fire pulse generator configured to receive signals corresponding to the temperature sensor, the temperature correction factor and the at least one drop ejector correction factor and to output a fire pulse waveform. Also included is a heating pulse generator configured to receive signals corresponding to the temperature sensor and the temperature correction factor and to output a heating pulse waveform. A waveform selector is provided for selecting either a fire pulse waveform or a heating pulse waveform based on the image data signal.
