Hi @stef541,

Welcome to The HP Support Community.  

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

I understand your HP Officejet 6812 e-All-in-One Printer is printing blank pages and not printing black ink, here are some steps you can try to resolve the issue:
 

1. Check Ink Levels

• Ensure that the black ink cartridge has sufficient ink. If it's low or empty, replace it with a new cartridge.

2. Clean the Printhead

• Sometimes, the printhead can become clogged, leading to issues with ink flow.
• You can clean the printhead using the printer's built-in cleaning function:
  1. On the printer’s control panel, go to the Setup menu.
  2. Select Tools.
  3. Choose Clean Printhead.
  4. Follow the on-screen instructions to complete the cleaning process.
• You might need to run this cleaning process 2-3 times to see improvement.

3. Manually Clean the Printhead

• If the automatic cleaning doesn't help, you can manually clean the printhead:
  1. Turn off the printer and disconnect it from the power source.
  2. Open the printer to access the ink cartridges.
  3. Remove the ink cartridges and gently clean the printhead contacts using a lint-free cloth dampened with distilled water.
  4. Allow the printhead to dry completely before reinserting the cartridges.
  5. Reconnect the printer and turn it on, then try printing a test page.

4. Check for Clogged Vents on the Cartridge

• Ensure the ink cartridge vents are not clogged:
  1. Remove the black ink cartridge.
  2. Inspect the small vent on the top of the cartridge.
  3. If the vent is clogged, gently clean it using a pin or paper clip.
  4. Reinsert the cartridge and try printing again.

5. Align the Printer

• Sometimes misalignment can cause print issues:
  1. On the printer’s control panel, go to the Setup menu.
  2. Select Tools.
  3. Choose Align Printer.
  4. Follow the instructions to complete the alignment.

6. Update Printer Firmware Update the firmware on an HP printer

• Ensure your printer's firmware is up to date. You can check for updates through the printer’s control panel or by visiting HP's official website.

7. Replace the Printhead (if necessary)

• If none of the above steps work, the printhead might be faulty and may need to be replaced.

8. Reset the Printer

• Sometimes a reset can clear any error states:
  1. With the printer turned on, disconnect the power cord from the printer and the wall outlet.
  2. Wait for 60 seconds.
  3. Reconnect the power cord to the wall outlet and the printer.
  4. Turn on the printer and try printing again.
