Hi I just had the same issues with my Epson SureColor P800 printer. I'm running windows 11 64Bit version. I went through all the suggested fixes including YouTube with no joy at all. Including uninstalling the printer, drivers and reinstalling the official drivers from Epsom manually, as the Epsom updater would not even register my printer was connected? definitely a driver issue on windows part.
So I resorted to clearing the setting from the printer it self using the touchscreen options. So far so good I've printed a Giclee print with no problems. Hopefully it's resolved as printing with these inks on this high quality paper is not cheap.
Hope this helps.
