Ink damper for 4-head DTF printers in 30cm format. With DTF inks, regular printer cleaning is necessary. However, despite regular maintenance, you may still experience printing problems. It might then be time to replace your dampers. The ink damper seal can wear out and allow air to enter. If this happens, you will notice gaps at the start of printing and poor print quality. We recommend replacing the dampers when changing the printhead.
