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 effective cleaning results.
This advanced method is implemented in the unified Print Head Doctor (PHD) and Print Head Tester (PHT) system, a professional-grade solution for cleaning and recovering clogged or deflected printheads from UV, solvent, and water-based printers.
How the Unified System Works
The unified system intelligently actuates piezo crystals inside your printhead during cleaning cycles. This process is:
Fully controlled via touchscreen software
Calibrated for different frequencies, waveforms, and durations
Integrated with specialized fluids like 11UV+, 1DX, and more
Key Effects of Piezo-Actuation-Assisted Printhead Cleaning:
Microscopic Vibration: Activating the piezo elements inside the printhead creates fluid movement within the nozzle channels, helping the cleaning fluid reach stubborn blockages.
Supercharged Chemical Action: Vibrations act like micro-pumps, improving penetration and circulation of cleaning fluids inside solidified ink deposits.
Mechanical Agitation: The system scrubs nozzle interiors from within using vibration patterns tailored to different clog types.
Efficient Flush-Out: Once ink is dislodged, induced flow helps carry out particles more effectively than flushing alone.
Why Piezo-Actuation Works Better Than Traditional Cleaning
Traditional Cleaning | Piezo-Assisted Cleaning |
Relies only on fluid chemistry | Combines fluid + vibration for deeper cleaning |
May miss compact or dry ink | Penetrates hardened deposits inside nozzle |
Risk of over-pressure | Gentle internal agitation = safer for delicate heads |
Limited effectiveness on deflected nozzles | Increases recovery of deflected and semi-clogged heads |
Benefits for Technicians & Print Shop Owners
Higher recovery success — Even on severely clogged or deflected heads
Faster turnaround — Reduced cleaning time by up to 50%
Reduced fluid usage — More efficient chemical penetration
Minimized downtime — Return printers to service quicker
Extended printhead life — Less wear from manual handling or excessive pressure
Compatible with Epson, Mimaki, Roland, Spectra, Konica, Ricoh, and more.
