  • Unclogging printer nozzles
    Patent number: 7360859
    Abstract: In one embodiment, a method for printing includes selecting a nozzle for printing a pixel, determining a time since the nozzle was last actuated, and, if the time since the nozzle was last actuated exceeds a threshold time, then, before actuating the nozzle to print the pixel, actuating the nozzle a number of actuations corresponding to the time since the nozzle was last actuated.

  • Printing system and method of printing an image in a fixed head printing system
    Patent number: 7350892
    Abstract: A method of printing an image in a fixed head printer system includes sensing a medium speed of a medium traveling in proximity to a plurality of ink printheads. A maximum optical density of the printer system at the sensed medium speed is determined. The firing frequency of the plurality of ink printheads is adjusted in response to a change in medium speed such that the maximum optical density of the printer system at the sensed medium speed is not exceeded.
