摘要： Described is a method which corrects for malfunctioning or inoperable ink ejection elements in a one-pass printmode. The method comprises obtaining the standard printmask; identifying the ink ejection elements which are malfunctioning; ascertaining ink ejection elements adjacent to the ejection elements which are malfunctioning; selecting particular adjacent ink ejection elements from the adjacent ink ejection elements; and modifying the standard printmask by adjusting the amount of ink deposited by the selected adjacent ink ejection elements to create a modified printmask.

摘要： A method of correcting for malfunctioning ink ejection elements in a printing system using a single pass over a recording medium which includes obtaining a standard printmask, identifying ink ejection elements which are malfunctioning, ascertaining an original color measurement value for each pixel which will be printed with the malfunctioning ink ejection elements, determining a replacement color measurement value closest in value to the original color measurement value which does not use the malfunctioning ink ejection elements for each pixel which will be printed with the malfunctioning ink ejection elements and modifying the standard printmask by adjusting the number and color of ink drops deposited based on the replacement color measurement value for each pixel which will be printed with the malfunctioning ink ejection elements to create a modified printmask.

摘要： A method for minimizing cross-contamination of print cartridges in an inkjet printing system due to aerosol drift by employing a bi-directional spitting scheme coupled with a configuration of the print cartridges. The method includes a carriage for traversing across a print medium and a spittoon, the carriage having a plurality of N receptacles, the receptacles identified from left to right as positions 1 through N, includes mounting a reactive print cartridge in either positions 1 and N, or both, on the carriage, the reactive print cartridges having a plurality of nozzles for ejecting reactive droplets and mounting a plurality of print cartridges in the remaining positions on the carriage, the print cartridges having a plurality of nozzles for ejecting ink droplets. During operation of the printing system, depending on the number of reactive print cartridges and the number of print cartridges and the location thereof, intermittently ejecting non-printing ink and reactive droplets from the print cartridges in a specific order while the carriage is moving in a transverse left to right direction and ejecting ink and reactive droplets from the print cartridges in a specific order while the carriage is moving in a transverse right to left direction.

摘要： The present invention includes as one embodiment a method of controlling an inkjet printhead assembly, including providing the printhead assembly having ink ejection elements that eject ink from a firing chamber through a nozzle and being energizable by an electrical pulse having a first predetermined energy, monitoring the printhead assembly to determine elapsed time since each ink ejection element on the printhead assembly has been fired, calculating a predetermined maximum amount of time that an ink ejection element is not operating using ink formulation and geometry of the nozzle and the firing chamber, comparing the elapsed time for each ink ejection element on the printhead assembly with the predetermined maximum amount of time and initiating high energy spitting at a second predetermined energy for the printhead assembly if the predetermined maximum amount of time has been exceeded for at least one of the ink ejection elements on the printhead assembly.
