You may need to run the cleaning fuction on your printer to clean the black print heads.

Every month (once a month), you need to clean your print heads to prevent your heads from clotting.

You are now seeing the symptoms of what happens when you do not constantly maintain your cleanliness of your print heads.

If that does not work, try buying a new black cartrige to see if the original black cartrige is defective.

If the above does not work, you may have a failing carrage and may need replacing

But do all of above first and get back to me with what happend during your diagnosis of your issues.

check your printer settings, make sure color only is not checked off, or if you mainly print black and white documents, you should have that option checked, you may have to go into advance printer options to do this.

print heads are likely to have clogging if used for a long time. deep clean them with the tools in the maintainace tab in the printer properties option.

1ST CLEAN PAD THEN TRY DELETING DRIVER REBOOT COMPUTER, THEN REINSTALLING THE DRIVER.

may have gotten a bad cartridge ! try another one !!

The ink your purchased is likely a cheap watered down version of what your printer is meant to take. You may notice that the ink smears when you rub the page directly after printing. Why you chose to use the blue and red ink to make black blows my mind. These refill kits are insanely cheap and buying the black could not have been much more. Not using black ink in the black cartridge would explain why your print is faded. Also, there is no way to reset the ink levels on this type of cartridge. As long as the printer still prints, just ignore the ink level indicator and print until the ink runs dry. I recommend Cartridge World for ink refills because they use high quality ink to manufacturer specified volumes while still saving you money.

You need to clean the nozzle of the ink cartridge. If this does not work, you need to replace the cartridge.
