Epson xp-235 purging problem

We are doing a project for TU Delft in the netherlands. We control 1 single nozzle a try to print active devices. We only have a problem that the printer purge at the beginning, after 80 droplets and at the end. Doe somebody know how to shut down the automatic purging?

This is a firmware issue sadly so I doubt there is a fix unless you re-flash the firmware.

That being said, Epson firmware is just a bundle of mostly open-source components (embedded Linux, etc) so it could be easy to get into for your own purpose.


Thank you

You know how to flash the firmware or are there already some topics about it.
or an already working open source-component

I do not have that skillset. You will have to do more research I’m afraid.
