摘要： A printer having precision ink drying capability and method of assembling the printer. The printer comprises a print head that is adapted to eject a plurality of ink drops through outlet orifices defined by the print head. The ink drops form a plurality of ink marks at a plurality of locations on a recording medium positioned opposite the outlet orifices. A plurality of heaters is disposed near the print head for heating the ink marks on the recording media in order to dry the ink marks. Drying the ink marks fixes the ink to the recording media. A plurality of sensors, that are disposed near the print head are also coupled to respective ones of the heaters for sensing the locations of the ink marks on the recording media. In addition, a controller interconnects each of the heaters to respective ones of the sensors for selectively energizing the heaters according to the locations of the ink marks sensed on the recording media by the sensors. Thus, the controller selectively informs the heaters of the locations of the ink marks on the recording media as the sensors sense the ink marks. In this manner, the heaters dry only the locations having ink marks with optimized energy output.

摘要： A swath printing system and pixel depletion methods compensate for the effects of defective printing elements by adjusting the pixel depletion mask used during printing to minimize the amount and location of extraneous unprinted spaces caused by the defective printing elements. A printing element quality detector determines which printing elements are functional and which are defective. Based on this information, an image processor then selects or constructs a depletion mask having depleted pixel positions chosen to reduce the adverse effects on print quality caused by the defective printing elements, thus maintaining high image quality for the printed output. Pixel depletion is preferably performed at the image pixel level, but can alternatively be performed at the color plane pixel level.

摘要： A high density graphics image can be printed without smearing by contact with a second page, without any unnecessary reduction of throughput. Throughput enhancement logic is inhibited during the printing of the second page for a variable delay related to the image density of the first page. The variable delay is calculated as a linear function of both the density (relative to a predetermined grid size) and the location if the densest portion of the first page, using coefficients which are different for different print modes. In one preferred embodiment, a maximum density is calculated by counting drops of ink in each of several overlapping grids, and the magnitude and location of the maximum density grid on a prior page is used to limit the throughput of a next page until a sufficient delay has elapsed to ensure that ink on the prior page will not be smeared when it comes into contact with the next page.

摘要： To prevent rubbing of the printing mechanism against still wet ink on a buckled or curled sheet of an absorbent print medium after an inkjet printer has printed one swath of a high density image, printing of the next swath is delayed as a function of the maximum density of the ink drops deposited on the print medium for the printed swath(s). The required delay in printing the next swath is dependent on print mode and preferably uses a formula with empirically derived constants to allow sufficient time for the solvent in the ink to evaporate or otherwise disperse and to permit any buckling or curling of the print medium to stabilize. In one preferred embodiment, a maximum density is calculated by counting drops of ink in each of several overlapping grids, and the magnitude and location of the maximum density grid on a prior page is also used to limit the throughput of a next page until a sufficient delay has elapsed to ensure that ink on the prior page will not be smeared when it comes into contact with the next page.

摘要： A swath printing system and under/overprinting method compensate for the effects of defective printing elements by adjusting the under/overprinting map used during printing regions of a uniform color, typically black, to minimize the adverse impact on print quality of unprinted “white space” caused by the defective printing elements. A printing element quality detector determines which printing elements are functional and which are defective. Based on this information, a print controller then selects or constructs an under/overprinting map having under/overprinting pixel positions chosen to reduce these adverse effects on print quality caused by the defective printing elements, thus maintaining high image quality for the printed output.

摘要： A method for improving the quality of printing processes involving black pixel depletion by printing composite ink in pixel spaces where a black pixel depletion process leaves unfilled pixel spaces. Black pixel depletion data are employed (for example, a depletion mask is inverted) to generate a composite printing mask which designates pixel spaces which are candidates for being filled in with a composite ink. In a preferred embodiment, edge pixels of black fill areas are excluded from the candidate pixels. In a preferred embodiment, the white pixel spaces are filled in by printing a plurality of different colored inks (e.g., cyan/magenta/yellow or cyan/magenta) within these unfilled pixel spaces. In a preferred embodiment, the composite printing mask additionally serves as an under/overprinting (UOP) map.

摘要： An inkjet printer (10) has a movable carriage (12) supported above an ink-receiving medium by a rail (14) defining a carriage axis. A cartridge holder (16) is mounted on the carriage and having at least one cartridge compartment (18), each of the at least one compartment having a compliant compartment wall (82). Each compartment is providing with an opening at one end (19) of the carriage floor for receiving the snout (72) of an ink jet printer cartridge (20) on which is mounted a nozzle plate with more that one nozzle for depositing ink onto the ink-receiving medium. Each compartment is also provided with equalizing structure for maintaining the cartridge substantially perpendicular to the carriage axis when the compliant compartment wall is deflected by a spring at the middle of the compartment forcing two datum surfaces on the cartridge against front and rear supporting surfaces on the compartment wall. The equalizing structure preferably includes a second opening (21) at the other end of the floor.
