Good Morning! I didn't my Epson L3150 for colour printing for a while and now the printer only works - perfectly - when printing in black and white. The ink cartridges are nearly full except the black ink cartridge. I think the nozzles must be clogged or dried. I've already tried cleaning using the printer's cleaning key and also via the desktop using escputil -c . In both cases the test page comes out flawlessly in black and white. But in color, practically nothing comes out.
Any suggestion as to how to do a thorough cleaning of the ink nozzles?
No support from Epson for linux, of course.
Running Ubuntu Mate 22.10, by the way.
