Black ink will not print

[rossgrp]

Printer will not print in black, only color.  I have changed the cartridge, just to be sure it wasn't a faulty one, but it has the same issue. Ran all the diagnostic tests, and the black just does not print.

HI @rossgrp,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

If your printer isn’t printing in black despite replacing the cartridge and running diagnostic tests, try these steps:

• Check Printhead: Remove and inspect the printhead for any visible damage or clogs. Clean it gently with a soft, lint-free cloth and distilled water if necessary.
• Perform Printhead Alignment: Use the printer’s menu or HP Smart app to run a printhead alignment. This can correct issues with print quality.
• Clean Printhead Contacts: Check the contacts on both the printhead and the cartridge for any ink build-up or residue. Clean them carefully with a soft, dry cloth.
• Run Deep Cleaning Cycle: Use the printer's software or control panel to run a deep cleaning cycle for the printhead. This can help clear blockages in the nozzles.
• Update Printer Firmware: Check for and install any available firmware updates from the HP support website. Firmware updates can resolve bugs affecting print quality.
• Check Ink Settings: Ensure that the printer settings are configured to use the black ink. Sometimes settings might default to only using color ink.

I hope this helps.

Take care and have a good day.
