Meteor wins patent for device detecting blocked inkjet nozzles

Meteor Inkjet says its invention uses real-time monitoring of electrical feedback from the inkjet nozzle to detect clogged or clogging print nozzles.

“Meteor Inkjet Ltd, leading supplier of electronics, software, tools and services for industrial inkjet, has been granted a US patent for “Inkjet nozzle status detection” (United States Patent No. 11,504,966) by the United States Patent and Trademark Office,” said the Cambridge, UK company, a subsidiary of Hybrid Software Group.

The patent covers a system and method for determining, in real-time, the operational status of a nozzle in a piezoelectric industrial inkjet printhead. 

“Conventional solutions to jetting issues are often sufficient for scanning printers in applications where multiple passes can mitigate the impact of nozzle failure,” Meteor said.  “But for single-pass systems running at high speed, or in applications where nozzle failure would have catastrophic consequences, existing inline imaging solutions are often complex and typically cost more than the print system itself.  Additionally, because camera-based solutions identify printhead problems after-the-fact, they have limited use for predictive maintenance.”

Fernando Rodriguez, Meteor’s VP of technology and the primary inventor, said: “Our invention uses real-time monitoring of electrical feedback from the nozzle after piezoelectric excitation to detect clogged or clogging print nozzles.  

"This disruptive innovation has the potential to remove a significant barrier to implementation of inkjet in applications where the impact of nozzle failure makes inkjet unsuitable.”

Meteor MD Clive Ayling added: “Over the last few years, Meteor has undertaken basic research to identify and develop ways to monitor and improve the reliability of the industrial inkjet printing process.  We are delighted that this invention has been recognised with a US patent and are confident that our ongoing investment in technological innovation will directly benefit not only our OEM customers but also the industry.”

Headquartered in Cambridge UK, Meteor Inkjet Ltd (www.meteorinkjet.com) is a leading independent supplier of industrial inkjet electronics, software, tools and services.
