摘要:
A particle removal device for an ink jet printer is discussed. The particle removal device includes a first separator comprising an arrangement of obstacles including at least two rows of obstacles that extend laterally with respect to a flow path of ink in the first separator. The rows of obstacles are offset from one another by a row offset fraction. The arrangement of obstacles is configured to preferentially route larger particles having diameters greater than a critical diameter through the arrangement and along a first trajectory vector that is angled with respect to the direction of the flow path of the ink. The angle of the first trajectory vector with respect to the ink flow path is a function of the row offset fraction. Smaller particles having diameters less than the critical diameter travel through the arrangement along a second trajectory vector that is not substantially angled with respect to the flow path of the ink. The first separator causes a pressure drop of the ink of less than about 100 Pa.
