Dell v515w printer won't print with black ink

Hello

I have recently changed the black ink cartridge of my DELL v515w printer and noticed it doesn't print with black ink anymore. When I try to print in black and white, it just spits out blank pages, and when I print in color, all the black accents are just left out.

Here's all the things I've tried until now (with no success) :

-Deepcleaning the printhead (3 times)

-Aligning the ink cartridges (2-3 times)

-Photocopying w/o the computer (gives blank pages)

-Cleaning the printhead manually with a piece of cloth

-Reinserting the old cartridge which still had a tiny bit of ink left (same result)

-Reinstalling printer drivers

-Resetting the printer to factory settings

-Disabling Demo mode

-Trying to print through wireless and through USB ( same result)

I'm a bit annoyed as I've already wasted half of the ink cleaning and aligning the printer, with no positive outcome.

I also came to the conclusion that the problem is definitely the printer, since photocopying didn't work either.

I've already spent loads of time trying to find a solution and at this point I'm a little desperate, so any help is welcome.

Thanks in advance.
