Photosmart C6300 series not printing black anymore, only colors

[CJinVa7]

Black ink cartridge has been changed and still not printing black. I had some difficulty Summer 2019 then it began to not print any black again. What is the problem?

Welcome to the HP Support Community.

Are you able to copy in black?

From the printer control panel, use an automated tool to clean the printhead.

NOTE: 

To avoid issues that require cleaning the printhead, always turn the printer off with the Power button on the printer itself.

1. On the printer control panel, press the Setup button .

2. Press the down arrow  to highlight Tools, and then press OK.

3. Press the down arrow  to highlight Clean Printhead, and then press OK.

   The printer cleans the printhead and then prints a test page.

If the issue persists, please perform the remaining steps from this document: https://support.hp.com/in-en/product/hp-photosmart-c6300-all-in-one-printer-series/3560272/document/...
