Printhead ink supply system comprising ink pressure regulator |
摘要 |
A printhead ink supply system is provided. The system comprises an inkjet printhead; an ink reservoir; an ink pressure regulator and an ink line connecting the printhead and the regulator. The ink pressure regulator regulates a hydrostatic pressure of ink supplied to the printhead and comprises an ink chamber having an ink outlet; an air inlet open to atmosphere; a bubble outlet for bubbling air bubbles into the chamber and an air channel connecting the air inlet and the bubble outlet. Each air bubble comprises an air cavity trapped inside a film or a body of ink and the bubble outlet is dimensioned to control a Laplace pressure of air bubbles drawn into the chamber as result of supplying ink to the printhead.
