My Deskjet 970CXI only prints in cyan and not in black.

I have tried all the solutions opted in this forum (cleaning,resetting) but to no avail.

The printout of the testpage is perfect, cyan and black.

The likely cause is an empty or defective #78 cartridge.  If you are printing with photo paper selected (or with automatic paper type settings and the paper is detected as photo) the black cartridge will not be used and the printer will try to make black using cyan, yellow and magenta.

 

If you print text with plain paper selected the printer should print properly in black.

Yours is an utterly ridiculous answer.

 

You cannot get black by mixing yellow, cyan, and magenta.

 

The closest you can come to black is brown - which are quite far apart in actuality.

 

I cannot believe you could get away with such an undeducated answer.
