I have a HP Officejet 6500 all in one E709A and the black cartridge not printing black ink.

[sandymoses]

My printer namely the black ink cartridge stopped printing. Placed a new HP black cartridge and it said, failure,  it was defective. I purchased another new one and it does not print. I went through all the different steps with the HP Solution Assistant online and did the quality testing. The colored cartridges are fine, but the black one does not print. please help.

Welcome to the HP support community.

Make sure that the cartridges are properly vented and seated correctly

1. If the printer is not already on, press the Power button to turn it on.

2. Open the ink cartridge access door.

   The carriage moves to the center of the printer. Wait until the carriage is idle and silent before you continue.

3. Press the tab on the front of one of the ink cartridges to release it, and then remove it from its slot.

      CAUTION: 

   Do not lift the gray latch next to the carriage to remove the ink cartridge. Doing so can result in incorrectly seated ink cartridges and printing problems.

4. Examine the vent area above the HP logo on the top of the ink cartridge.

5. If the ink cartridge still has the orange pull-tab attached, pull to remove it.

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

8. With the ink cartridge contacts facing the printhead, slide the ink cartridge into the correct slot. The color-coded icons on the ink cartridge and in the printhead indicate the correct slot.

9. Press down on the ink cartridge until it clicks firmly into place.

10. Repeat these steps to inspect the vents on each of the ink cartridges.

11. Make sure that each ink cartridge is firmly in place in its slot. Run your finger along the top of the ink cartridges to feel for any that are protruding, and if any are, press down firmly until each ink cartridge snaps into place.

12. Close the ink cartridge access door.

13. Try the print job again.
