My HP Office Jet Pro 6835 does not work well. I cannot print out any.  The message has shown up "The printer head has an issue" so I cleaned  up watiching the tutorial video but did not work.

Is there way I can fix this issue? If not, where can I drop this machinge for repair? I linve in Seattle.

Welcome to HP forums, I see that you are getting printhead issue.

Clean the ink cartridge vents and contacts

1. Gather the following materials:

   • A pin to clean any clogged vents

   • A clean, lint-free cloth

   • A clean, dry cotton swab

   • Distilled or bottled water

        CAUTION: 

     Do not use tap water because it might contain contaminants that might damage the printhead.

2. Examine the vent area located on top of the ink cartridge, next to the HP logo.

3. 

4. If any of the ink cartridges have clogged vents, use a pin to clean the vents.

5. Lightly dampen a fresh, lint-free cloth.

6. Wipe any accumulated ink and debris on the copper-colored contact on the ink cartridge.

      CAUTION: 

   Be careful to wipe only the ink cartridge contacts. Do not smear any ink or debris elsewhere on the ink cartridge.

   1. Ink cartridge contacts

7. Wipe the contact with a dry, lint-free cloth.

11. Wipe the contact with a dry, lint-free swab.

12. Reinsert each of the ink cartridges into its slot, and then push the ink cartridge forward and down until it snaps into place.

    Make sure each colored dot on the ink cartridge label matches the colored dot on the carriage.

    

13. Run your finger along the top of the ink cartridges to make sure none of them protrude.

    If any ink cartridges protrude, press down firmly until each ink cartridge snaps into place.

14. Close the ink cartridge access door.

15. Check the printer control panel display for the error message.

    • If the message is to Replace the, , , or Ink Cartridge, remove the specified ink cartridge(s) and clean the copper-colored contact again, and then reinsert the ink cartridge(s).

Update the printer firmware.
