This original Roland DG ink damper (part number 1000012719) is an essential component of the ink delivery system in large-format inkjet printers. It functions as a buffer and control module between the ink lines and the print head, where it captures and smooths out air and irregular ink flow to ensure a stable, consistent ink supply. By damping fluctuations and air bubbles, it prevents splashing, droplets, and print artifacts, thereby contributing to improved print quality and reliability.

This damper is white/transparent in color and specifically designed for use with Roland ESL inks; Roland recommends this model over the black mesh alternative (1000013784) for most solvent and eco-solvent applications.

It is compatible with a wide range of Roland large-format printers, particularly from the BN, VS, RA, RE, RF, and RT series, including models such as BN-20 and VS-300/420/540/640 and related types, making it a commonly used replacement part for maintenance and repair.
