Abstract: A method of operating a thermal ink jet printer with a removable print head having a plurality of ink firing resistors, the operation including calibrating the printer by determining a nominal input voltage above a threshold necessary for simultaneous operation of a plurality of the resistors. Then, during printing, detecting the input voltage on the print head at an input node connected to the resistors and generating a firing pulse having a duration based on the detected input voltage at the node. Thus, a detected input voltage higher than the nominal voltage is compensated for by a shortened firing pulse. The method may be achieved in a removable ink jet print head having a connector with many electrical inputs connectable to a printer, and a voltage input node connected to the connector. The print head has numerous firing resistors connected to the input node. An energy control circuit is connected to the input node and is connected to the resistors to fire the resistors with a firing pulse having a duration inversely related to the voltage at the input node, such that the firing energy is maintained in control by varying the firing pulse duration to compensate for voltage variations.

Abstract: An inkjet printing system having multiple independent power supplies for providing firing energy to the ink ejection elements of one or more printheads. Different ones of the power supplies can be connected to different print cartridges each of which prints a different color ink; to different arrays of ink ejection elements within a single print cartridge, where each array prints a different color ink; or to different sections of the ink ejection element array of a single printhead for a single color ink. The output of each power supply is independently set to an appropriate voltage level for each different print cartridge, ink ejection element array, or section of an array.

Abstract: The present invention is embodied in a system and method for optimizing ink drying time through the incorporation of a system of multiple spaced printheads. The printhead assembly includes connection and processing circuitry, multiple printhead bodies, ink channels, substrates, such as semiconductor wafers (commonly referred to as a die), and nozzle members. The printheads also include controllers for controlling printing on a print media and incorporating a programmable feedback loop. The loop activates the various printheads during printing so that the various data packets are added in a synchronized manner during the print swath. The present invention provides adequate drying time for inks produced in a printing swath on a wide array page. This will result in the use of water based inks compatible with ink jet materials in systems with fast raster scanning.

Abstract: An interconnection arrangement for an inkjet printing system having multiple power pads, each of which provides power for driving a large number of printhead ink ejection elements. The ink ejection elements of a print cartridge are organized into groups, with power provided to each group by one of the power pads. The firing pulse width of each group is independently set to compensate for the parasitic electrical resistances in the power path of each ink ejection group in the print cartridge so as to eject ink drops of uniform volume required for high quality printed output. In order to transmit the relatively high current levels required to fire a large number of ink ejection elements from a single group at the same time, the interconnection scheme provides multiple bump-and-dimple interconnections with the printer for each power and ground pad on the print cartridge.

Abstract: An ink jet printer having an ink delivery system that allows air to be absorbed by ink that is being delivered to an ink jet print cartridge that includes a thermal printhead, so that ink delivered to the printhead has an air saturation level of at least 30%. The dissolved air reduces damage to heater resistors of the thermal ink jet printhead that would otherwise be caused by the in rush of ink after an ink drop is fired.
