Abstract
An inkjet printing system includes at least one drop ejector array module having an array of drop ejectors disposed on a substrate. A primary temperature sensor is located near a first set of drop ejectors. At least one secondary temperature sensor is located near a second set of drop ejectors. Temperature comparison circuitry on the substrate is configured to compare signals from the primary temperature sensor and the at least one secondary temperature sensor. Pulse modification circuitry on the substrate is electrically connected to the temperature comparison circuitry and is configured to modify an input pulse waveform. The inkjet printing system also includes a controller that is electrically connected to the primary temperature sensor via a temperature output pad and to the pulse modification circuitry via a pulse waveform input pad.
