As a black and white photographer, I found this printer to be ideal. Before getting it, I had to use a dedicated printer with special mono inks to get good black and white prints. The R2400 delivers them without colour casts or noticeable metamerism.
One thing that did catch me out though, was that the printer driver has special settings for black and white. You ignore them at your peril.
I use Hahnemuele PhotoRag paper, and the results out of the box were very good. Add in the correct profile, and they were noticeably better. And that was the problem. Profiled, the results for colour were better, but in black and white, I found the reverse.
To get a good black and white print, I needed to turn off the profile, and use the printer driver advanced black and white settings. Without doing this, the print of a step wedge showed maximum black was reached at about 85% black, meaning that the shadows were far too dark. I admit to being lazy; I stopped when I could see a discernible difference all the way up the scale from 0% black to 97% black. For an easy life, I've let the really dark shadows go black...
