HP Smart tank 515 not printing a specific Color

For context, my Smart tank 515 does not print the color yellow. It just happened when I tried Printing a document. I've noticed that my the document came out wrong, so I tried to print a Rainbow Spectrum to see what color was missing, and It was yellow. I've Check the inside of the printer for any complications within the hardware but couldn't find any. I've Also tried Cleaning the smears the printhead. But the result is all the same. Should I try replacing the printheads or pump the printhead for the ink yellow.
