Lexmark Corporate Background Information

  3. Print Defect - Small ink droplets are blown away by the air flow of the print head as it moves left and right. - The small particle does not hit the target but instead creates “tree veins” (below) on the paper. Problem Statement

  4. Dirty Printer - Small liquid particles (1.1-1.5 nanograms) mix with air flow due to the print head movement and end up misting the inside surface of the printer. Problem Statement Continued

  5. Use the Vanderbilt water tunnel (thus choosing water as the fluid medium due to the ability to dye flow patterns) to study flow over a container to better understand the flow disturbances it creates. This will then allow for inconsistent print patterns such as veins to be corrected. Empirical Problem Statement

  6. Needs Ink particles to hit target (accuracy) Veins to go away Clean printer (no small flying ink particles) Wants Inexpensive Simplicity in solution Less mess Environmentally friendly

  7. Questions/Comments?
