摘要： An apparatus and method compensates for a voltage drop of electrical pulse signals selectively applied to a plurality of heater elements on a printhead of an ink jet printing device. A number of heater elements to be pulsed at a given time is determined and a time duration of each of the pulse signals is selected based on information including the determined number of heater elements to be pulsed. In another aspect, the position on the printhead of the heater elements to be pulsed is determined and the time duration of the pulse signals is selected further based on the determined position. By varying the time duration of the pulse signals applied to the heater elements, a voltage drop across the heater elements due to the number of heater elements simultaneously pulsed and/or the position of the heater elements on the printhead is compensated for, maintaining reliable jetting performance while minimizing the voltage by which operating printing voltage needs to exceed the threshold printing voltage.

摘要： A thermal ink jet printer is provided with an improved interconnection between the heater elements in the printhead and the remote source for the thermal energy print signals. The printhead is bonded to a first electrode board which has a plurality of electrode leads formed on both surfaces. The leads connect to the input pads of the resistor heater elements and terminate at discrete points over a large portion of the boards' surface. The electrical connections to the remote source are completed via a second electrode board placed in a mechanical and electrical contact with the first board. Conductive raised pads on the second board are in alignment with the terminal pads on the first board and are held in pressure contact therewith.

摘要： A method for electrical tailoring of thermal ink jet heater elements. The resistance of ink-jet heater elements formed of polysilicon is changed by applying energy through the resistor element of varying amounts at varying pulse widths. The application of pulsed current for up to 1 second total pulse width at voltages of up to 50 volts decreases the resistance by as much as thirty percent or more of the as fabricated values.

摘要： A system controls an ink jet printing apparatus for propelling ink jet droplets on demand from a printhead having a plurality of drop ejectors. In the printhead, each ejector includes a heating element actuable in response to electrical input signals, each input signal having an amplitude and a time duration, selectably applied to the heating element to produce a temporary vapor bubble and cause a quantity of ink to be emitted for the creation of a mark on a copy sheet. The temperature of ink in the printhead is sensed, and a combination of power level and time duration of the electrical input signal for the heating element to result in a desired size of the mark of the copy sheet is selected, by entering the sensed temperature of the ink into a predetermined function relating the energy of the electrical input signal to the corresponding resulting size of the mark on the copy sheet.

摘要： A method and apparatus for maintaining a print quality of an ink jet apparatus comprises selecting one of a plurality of different pulse signals to apply to at least one heating element. The heating element is energized with the selected pulse signal. An actual voltage drop is then measured across the heating element. The actual voltage drop is subsequently compared with a desired voltage drop. Then, a new pulse signal is selected to energize the heating element based on the results of the comparison. The repetitive process continues until the actual voltage drop is substantially equal to the desired voltage drop. In another embodiment, a bubble sensor is used to determine whether a bubble has been formed over the heating element.
