Order by 5 pm for same day shipping from California
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!
