Ink system problem

[Ulivau]

Recently, my printer (HP OfficeJet 6600) has stopped working and I get the error message "Ink system problem - The printhead is not seated properly appears to be missing or not recognized." I haven't changed anything or messed around with the printhead.

Hi @Ulivau,

Welcome to HP Support Community.  

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

It seems like you're encountering an issue with your HP OfficeJet 6600 printer related to the printhead. This error message typically indicates that the printer is having trouble recognizing or detecting the printhead. There are several steps you can try to resolve this problem.

• Restart the Printer: Sometimes, a simple restart can resolve minor glitches. Turn off the printer, unplug it from the power source, wait for a minute or two, and then plug it back in and turn it on.
• Check Printhead Connections: Ensure that the printhead is properly seated in its carriage and locked in place. Open the printer cover to access the printhead, gently remove it, and then reseat it firmly. Make sure you hear a click when you reinstall it.
• Inspect the Printhead Contacts: The printhead has electrical contacts that connect to the printer. Make sure these contacts are clean and free of any ink residue or debris. You can clean them with a lint-free cloth or a cotton swab lightly moistened with distilled water.
• Update Firmware: Check if there are any firmware updates available for your HP OfficeJet 6600 on the HP support website. Updating the printer's firmware can sometimes resolve compatibility issues.
• Check for Printhead Damage: Examine the printhead for any visible damage, such as clogs, leaks, or dislodged parts. If you notice any physical damage, you may need to replace the printhead.
• Replace Printhead: If the issue persists and the printhead appears to be in good condition, it's possible that the printhead itself is faulty. In such cases, you may need to purchase and install a new printhead. Be sure to get the correct model of printhead for your printer.

I hope this helps. 
 

Take care and have a good day.
