<p>The device is used for controlling the energy supplied to an emission resistor (15) of a thermal ink jet printhead by determining directly in each head fitted on the printer the amount of energy needed for the emission resistor to effectively reach the temperature of enucleation of the bubble, and accordingly regulating either the intensity or the duration of the current pulse supplied to the resistor, thereby compensating for all the variables and deviations of the printhead manufacturing process and also for the different driving characteristics of the various printers on which the head can be fitted.</p> |
