Abstract: A removable data cartridge is protected from air-transported particles such as dust, excessive moisture, contaminants, and the like by filtering or otherwise conditioning the airflow at initial startup. The recording media in the data cartridge is initially spun at a rate of speed higher than the operating speed for a brief period of time. By spinning the media at the increased speed, any particles in the cartridge will be removed by the filters. After the initial cleaning period, the spin speed of the media is reduced to a normal operating level.

Abstract: One or more reactive color inks are printed under and over black text and graphics areas. That is to say, one or more reactive color inks are first printed in a selected area in which black text and/or graphics are to be printed, then the black text and/or graphics are printed, and finally one or more reactive color inks are then printed over the black text and/or graphics. The use of under- and over-printing of black text and/or graphics by reactive color inks improves several important characteristics of inkjet printing. Specifically, the following improvements are obtained: dry-time, finger smudge, media independence/print quality, waterfastness, strikethrough, less noticeable missing/misdirected nozzles, and no dedicated pens are required. Alternatively, either underprinting alone or overprinting alone may be used.
