Discover how the unified Print Head Doctor (PHD) and Print Head Tester (PHT) system uses piezoelectric actuation to supercharge printhead cleaning, improve recovery rates, and reduce printer downtime. What Is Piezo-Actuation-Assisted Printhead Cleaning? Piezo-assisted printhead cleaning  combines: Chemical cleaning  (using specialized printhead recovery fluids), and Mechanical stimulation  (activating the printhead's piezoelectric crystals) to create deeper, faster, and more
