If these are BCI3 BLK cartridges they may be old or the pigment has separated.
Shake the cartridge and hit it lightly on a towel to see if ink comes out. If it does (I mean an amount close to the hole size) try a nozzle test.
If that does not work you may have to deep clean the head.
thank you for using Fix-Ya

Set the printer to print black only, no color, and see if that helps. If not, put in a new black cartridge and test using the same setting. Does it work now?

    I found that if I refilled my own ink cartridges, the print quality became more inconsistent over time. The answer for me was to buy new cartridges (The cheap ones from ebay), and continue refilling them for say, 3-4 times before buying new again

Why do I have white / faded print when printing black? It also has problems printing straight lines - sometimes jagged sometimes just faded.


I do not know for sure but it sounds like the paper is not griped properly, this would cause the jagged lines. I would try another ink cart when the loose paper problem is resolved. I hope this helps.

Print keeps fading, even though using new ink


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.

Looks like a braille text


Open the HP Printer Toolkit (this software was installed from the CD-ROM that came with the HP printer) and run a "cleaning cycle",
because some of the ink-jets are clogged, which results in the "all-white" horizontal lines, where some part of that line should be black.
