Hi @Ron78120,

Welcome to The HP Support Community.  

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

I understand the error code 0xc19a0036 on your HP OfficeJet Pro 6968 All-in-One Printer typically indicates a printhead problem, usually related to a clogged or defective printhead. Here are some steps you can take to try to resolve this issue:
 

1. Reset the Printer

• Turn off the printer.
• Unplug it from the power source and wait for at least 30 seconds.
• Plug it back in and turn the printer on.
• This can sometimes reset internal components and resolve minor issues.

2. Check the Printheadas

• Open the printer cover and remove the ink cartridges.
• Gently lift the printhead and check for any visible dirt, ink clogs, or debris.
• Use a lint-free cloth and some distilled water or printhead cleaning solution to clean the contacts on both the printhead and the printer.
• Carefully wipe the printhead and the area it sits in to remove any residue.

3. Clean the Printhead Using the Printer's Cleaning Function

• Many HP printers have a built-in cleaning function to help clear clogs from the printhead.
• On your printer’s control panel, navigate to Settings > Printer Maintenance > Clean Printhead. Follow the on-screen instructions.

4. Check for Firmware Updates Update the firmware on an HP printer

• Ensure your printer's firmware is up to date. You can check for updates by going to Settings > Printer Updates or by visiting the HP Support website and entering your printer model.

5. Replace the Printhead (if necessary)

• If the printhead is severely clogged or damaged and cleaning doesn't resolve the issue, you may need to replace it. Check the HP website for replacement parts or visit a local service center.

6. Perform a Hard Reset

• If none of the above steps work, perform a hard reset by holding down the Power and Cancel buttons for 15-20 seconds. This can sometimes clear persistent errors.
