PRESSURE DAMPER OF INKJET PRINTER

摘要

PURPOSE:To realize a highly reliable ink feed system in a simple structure by providing a mesh filter for filtrating an ink at an ink discharge section. CONSTITUTION:A pressure damper of this invention is mounted in an inkjet head 1 or a head carriage between the inkjet head 1 and an ink tank 2. The pressure damper 3 has a mesh filter 5 provided at an ink discharge section 4 immediately below a pressure absorbing part 6 thereof for filtrating ink. Specifically, the mesh filter 5 is placed at such a position that the air bubbles caught by the filter 5 are moved into the pressure absorbing section 6 when the bubbles are separated from the mesh filter.
