If your HP printer has plenty of ink but you still get faded prints or text is too light, then the problem will be related to the print head or nozzles being blocked or damaged. Solution: Run a diagnostic print from the printer menu to confirm which colours are causing a problem.
If your HP printer not printing black ink correctly, here`s what you should do. Using non-genuine ink cartridges. Printheads that have become clogged. Ink cartridges that are defective or empty.
Check you have the latest drivers installed for your printer, try uninstalling and reinstalling your printer drivers or try changing the driver settings (adjusting the paper settings has been known to solve the problem). Fully Reconfigure the Printer – If all else fails, you can try entirely reconfiguring your printer.
The answer is yes, your printer uses a bit of all colors (black, cyan, magenta, yellow) every time it prints. According to HP Support, “[our] printers are designed in such a way that it also uses color inks while printing in black to form a perfect black.
If the ink level is sufficient, but the printer still does not print black ink, you may need to run a cleaning cycle. A cleaning cycle is a process that cleans the printer heads and removes any clogged or dried ink.

If your PC or the LCD screen on your printer is telling you that your ink cartridges are full but no ink is passing through to the paper, then it`s most likely that you are dealing with a clogged printhead.

Grayscale printing requires a mixture of ink other than black, as it uses some other colors other than black ink. At the same time, black ink for printing is the only ink used for grayscale printing. While gray-toned colors are combined, these other tones also result in a grayscale image.
A gray cast indicates that the drum is not getting or holding a sufficiently strong charge to hold the toner. It looks like either the OPC drum or the corona wire/primary charge roller is not working correctly. Try replacing the cartridge (the drum is part of the cartridge in many HP laser printers, including yours).
