Hi @Kerri1949-_,

Welcome to HP Support Community.

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

To clean the printhead of your HP Officejet Pro 6835 printer, you can follow these steps.

Using the Printer's Built-in Cleaning Function

Turn on the Printer: Make sure your printer is powered on.

Access the Control Panel:

• Tap on the Setup icon (the gear icon) on the printer's control panel.
• Navigate to Tools or Printer Maintenance (the exact wording may vary).

Select Clean Printhead:

• Look for the option labeled Clean Printhead or Clean Printheads.
• Select this option and follow the prompts to start the cleaning process.

Print a Test Page:

• After the cleaning cycle is complete, print a test page to check if the issue is resolved.

Manual Cleaning of the Printhead

If the built-in cleaning does not resolve the issue, you can manually clean the printhead:

Prepare for Cleaning:

• Turn off the printer and unplug it from the power source.
• Open the printer cover and wait for the printhead to move to the center.

Remove the Ink Cartridges:

• Carefully remove the ink cartridges and set them aside.

Remove the Printhead:

• Locate the printhead assembly and gently lift it out. Refer to your printer manual for specific instructions on removing the printhead, as it may vary slightly.

Clean the Printhead:

• Use a lint-free cloth or paper towel dampened with distilled water or isopropyl alcohol.
• Gently wipe the nozzles and contact points of the printhead to remove any dried ink.

Soak the Printhead (Optional):

• For stubborn clogs, you can soak the printhead in a shallow dish with distilled water or a cleaning solution for a few hours. Ensure that only the nozzle area is submerged.

Dry and Reinstall:

• Allow the printhead to dry completely before reinstalling it into the printer.
• Reinsert the ink cartridges.

Run a Test Print:

• Plug in the printer, turn it on, and print a test page to check if the issue is resolved.

Note:

• Make sure to use genuine HP ink cartridges, as non-genuine cartridges may not work properly.
• Perform printhead cleaning regularly to prevent clogs.

I hope this helps.

Take care and have a good day.
