Roland Damper BN-20 #RO1000012719

Roland BN-20 Ink Damper – P/N RO1000012719

The ink damper on your Roland BN-20 plays a critical role in maintaining consistent ink flow from the cartridge to the printhead. It buffers pressure fluctuations, filters micro-particles, and prevents air from entering the ink line — all of which directly affect print quality and printhead longevity.
