Hi @AdrianoRT77,
Welcome to The HP Support Community.
Thank you for posting your query, I will be glad to help you.
I understand you are facing an issue with your HP Smart Tank 530 is experiencing an issue with the black ink when printing in high-quality mode. Here are some steps to troubleshoot and resolve this problem:
1. Check Ink Levels
- Ensure the black ink tank has sufficient ink and is not running low. Refill it if necessary.
2. Run Printhead Cleaning
- Even if you’ve already cleaned the printheads, run the cleaning utility again from the printer's control panel or through the HP Smart app.
- Perform multiple cleanings if needed (up to three times), as sometimes one cleaning cycle may not fully resolve clogs.
3. Align the Printheads
- Aligning the printheads can help resolve issues with print quality. You can do this from the printer's settings menu or the HP Smart app.
4. Perform a Nozzle Check
- Print a test page to verify the black ink nozzle’s performance. If lines or sections are missing, the issue may be with the nozzle.
5. Inspect the Printhead
- Check if the black ink printhead has any visible clogs or dried ink. Gently clean the printhead contacts with a lint-free cloth and distilled water.
6. Check the Print Settings
- Ensure the printer is set to use the correct paper type and quality settings. Sometimes incorrect paper settings can cause issues in high-quality mode.
- In the print dialog, set the paper type to "Photo Paper" if you are using glossy or photo paper.
7. Update the Printer Firmware Update the firmware on an HP printer
- Ensure your printer’s firmware is up to date. You can check for updates via the HP Smart app or HP’s website.
8. Reset the Printer
- Turn off the printer, unplug it for 5-10 minutes, and then power it back on. This can resolve some software-related issues.
9. Test with Different Software
- Try printing the same document using different software to rule out software-specific issues.
I hope this helps.
Take care and have a good day.
