Epson 4530 black ink

I have Durabrite ITDB-700-K in my Epson WP-4530 printer. This has been a fantastic printer for me, and the inks have done really well in this printer. Until the last couple of weeks. The colours print well, but the black is coming out grey. It’s almost as if the printer is in an “eco mode”, but I cannot find any such setting. Besides, the colours are printing more vividly than the black.

My nozzle check is perfect, and I just ran a print head alignment just in case. I’m out of ideas.

I’m not sure. It could just be that the cartridge needed agitation and it never got that and you printed out the black pigment.

warm regards
