Abstract: A method and apparatus for a test pattern used in the alignment of an ink-jet pen which deposits fixer fluid, or other clear ink precursor fluid, on print media uses the change in reflectivity caused by overprinting a series of positional-calibration indicia with colorant to obtain data with respect to deviations in a carriage-scan x-axis and a paper scan y-axis. Thus the invention measures distances between pens or nozzles.

Abstract: An inkjet printer uses a printhead that passes repeatedly across a print medium in individual swaths. The printhead has individual nozzles that are fired repeatedly during each printhead swath to apply an ink pattern to the print medium. Before any given swath, the printer analyzes factors that might require a reduction in print density. Anticipated printhead temperature is one factor that might require a reduction in print density. The printer monitors the print density and peak printhead temperature during each printhead swath. It then uses these values to calculate, prior to each new swath, a maximum permissible print density. If a reduction in print density is required, the printer temporarily disables selected nozzles to produce a reduced-height swath rather than pausing between swaths or reducing the printhead velocity relative to the page.

Abstract: A printer automatically selects the print mode depending upon media type. The printer has a media handler to convey media through the printer and a media sensor to detect whether the media is transparent. The printer also has a printing mechanism configured to print a print file using a print mode that is selected based upon the type of media detected by the media sensor and whether the print file is intended for that media type.
