my hp photosmart6520 does not print in black ink

[Charley0140]

My hp photosmart printer 6520 will not print black ink.  Color inks are very low from printing test pages.  No other changes were made after new cartridges were purchased.  If I need to uninstall/reinstall, I will need some instructions.  Please help!

Welcome to the HP support community.

Check the ink cartridge vents

1. Open the ink cartridge access door.

   

2. Press the tab on the front of the ink cartridge to release it, and then pull it out of the slot.

   

3. Examine the vent area on the top of the ink cartridge.

   

4. If the vent is clogged, use a pin to gently remove excess adhesive from the vent.

   1. Clogged vent

   2. Gently remove excess adhesive from the vent

   3. Unclogged vent

5. Make sure the orange pull tab is completely removed.

   

6. Insert the ink cartridge into its slot. Press down until it snaps into place.

7. Repeat these steps for any other ink cartridges with defects on the report.

8. After reinserting all the ink cartridges, run your finger along the top of the ink cartridges. If any are protruding, press down firmly until each ink cartridge snaps into place.

9. Print another Print Quality Diagnostic report.

I followed all the recommendations.  I have printed the quality diagnostic report.  It prints with black ink on that.  However, if I print a document from my computer it does not print in black.  If I change the color, it prints.
