Although I always use official HP cartridges and all the colours are full , my printer doesn't print black.
Thank you for posting your query on HP Community,
What is the product number of your HP Printer? Use this link to find it: https://support.hp.com/in-en/document/c03754824 (Ensure you do not share any of your personal information such as serial, phone number, email ID, etc...).
Have you recently made any changes before the issue started?
Did you try to print the print quality diagnostic page from the printer or print the printer self test page?
Have you tried to clean the ink cartridge contacts?
Please respond to this post with the details so that I can provide you with accurate steps which should help you resolve this issue.
Eagerly waiting for your response!
Thank you 🙂
