Buongiorno Carlo di Lago di Garda (Ci sono stato, bel'posto!)


I am not an expert in these large printers but did a bit of exploring and someone else asked the same (or similar) question here  . It may cover the same the same issue.

Full link.


On page 2 it speaks about issues with the Designjet T520 Encrypted chip and it needing replacement.
There are also some troubleshooting steps you might want to try out.


Buona fortuna ( bocca lupo?)
