Have an Epson P600 that does a nice job. Problem is that it prints too dark much of the time.

Calibrated system but the prints are too dark.

I lighten them on the screen after seeing the print come out much darker than I like and have the settings "right".

Still too dark and at times no change in the print, even after making the file much lighter on screen.

Same problem with either Printer or Photoshop manages colors.

Same problem with either B&W and Color, though it seems to be more with B&W - Advanced B&W than color.

Right now using glossy paper but happens with matte as well.

All factory inks and good alignment, no skips in the printed nozzle check.

Just prints too dark.

What am I missing?
