Dampers for Roland DX4 printheads. These are solvent resistant and will also work well with water based inks. It is recommended that you change the dampers and O-rings with every head change. Dirty dampers impede the flow of ink and you'll get frequent drop-outs, missing jets and ink starvation. Eventually, neglected dampers will damage to the printhead because of overheated jets. If you have a problem where the ink constantly gets drained out of the dampers and ink lines – back into the cartridge, you have an air leak. Replacing the O-Ring and screw usually cures this problem. Remember that each printhead uses 2 dampers!
