For significant changes from GTX-3, refer to the section below: 1-6-1. Details of the print head GTX-4 incorporates the latest print head technology available to compound ink-jet printers, significantly improving the printout speed and printing quality by adopting high-density print nozzles.
  • Page 38 Before Using Your Printer for the First Time Back-end components and their primary functions Damper assy Damper functions to buffer the dynamic pressure of inks within the ink supply tubings during the travel of the carriage and to retain the bubbles created within the ink from the variation of pressure. : Dynamic pressure of ink: Ink is subjected to the inertia to maintain its position within the tube despite the travel of the head / carriage unit.
  • Page 39 Before Using Your Printer for the First Time Damper functionality Each damper is divided into two chambers, with film attached to the top of the chamber to the right as indicated within the diagram. The film is loosely attached to allow it to expand outward corresponding to the increase of pressure and relax inward when the pressure decreases due to the dynamic pressure variation within the ink supply tube, thus serving to buffer the pressure.
  • Page 40 Before Using Your Printer for the First Time <TIPS: Development of air bubbles>  Minor quantities of air are dissolved in the fluid ink. The quantity of the dissolved air changes depending on the pressure applied. Under high pressure conditions, the quantity of saturated air content increases, causing more air to dissolve into the ink. When the pressure decreases, the quantity of saturated air content is reduced to cause the air to escape from within the fluid.
  • Page 41 Before Using Your Printer for the First Time <TIPS: Problems caused by the development of air bubbles>  What happens when air bubbles are created within the ink? The volume of ink does not change under pressure variation while the volume of air changes when subjected to pressure (Boyle's law).
  • Page 42: About White Ink Circulation Functionality

    Before Using Your Printer for the First Time 1-6-2. About white ink circulation functionality The white ink contains titanic oxide with high rate of subsidence and must be agitated at regular intervals. The White Ink Circulation functionality causes the ink within the tubing between the white ink cartridge and the white print head to flow in order to agitate the titanic oxide and prevent the ingredient from subsiding.

  • Page 44: About Closure Cleaning

    If printers equipped with white ink are neglected over prolonged periods of time, the print head may dry up and cause the nozzles to clog. GTX-4 incorporates the closure cleaning functionality as an attempt to resolve this issue. Closure cleaning is a process to replace the ink content of the white-side cap with cleaning solution. Closure cleaning is initiated when the printer is left idle for a certain duration after the completion of the printing, or when the printer is shutdown by pressing the Power switch.
