Epson WF-3620 Failed after firmware upgrade

[Robert42]

The Epson Updater told me that there was updates to my WF-3620 MF Printer. This included Firmware. It seemed to install OK and no error messages. The problem came about when it restarted. It went through a head cleaning process twice and then shut down. Turned it on again with a message that the heads were blocked and needed cleaning press OK and it repeated. Connected to Windows with USB and the printer was recognised. I tried to put the printer in a fault condition by removing the cartridges but it was unable to recognise they were out.

Could this be one of those firmware updates I have read about to stop using compatible cartridges or is there a failure with the firmware. I have D/L the recovery firmware but no tool to install it.

Help needed.

Can you please pass on your computer's system's specs and OS? Based off of this link, you should be able to run the executable from your machine while the printer is connected. Just be sure to run the executable in an elevated command:
Right click executable>Run as Administrator
and see how that goes.
