printhead malfunction

[Mylor]

Printer tells me the printhead appears to be missing or is incorrectly installed. I follow the directions on the video. No change.

Do I need a new printhead?

Hi @Mylor,

Welcome to HP Support Community.

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

A "printhead malfunction" error can be quite frustrating, especially if you’ve followed the installation steps and still see the error. Here’s a detailed guide to troubleshooting and resolving printhead issues with your HP Envy 5540:

1. Check Printhead Installation

• Power off your printer and unplug it from the power source. Wait about 60 seconds.
• Open the printer’s access door to access the printhead and ink cartridges.
• Gently remove the ink cartridges from the printhead. Set them aside on a clean surface.
• Carefully remove the printhead from its slot. You may need to release a latch or handle depending on your printer model.

Inspect the Printhead:

• Check for any visible damage or obstruction in the printhead and the printer’s carriage.
• Look for any tape or protective covers that might still be on the printhead.
• Use a lint-free cloth or a cotton swab lightly dampened with distilled water to clean the contacts on the printhead and inside the printer where the printhead connects.
• Carefully reinstall the printhead into its slot, ensuring it’s securely in place.
• Reinsert the ink cartridges into the printhead.
• Close the printer’s access door and plug it back in.
• Power on the printer.

2. Check for Firmware Updates

Sometimes, firmware updates can resolve printhead issues.:

• Visit the HP Support website and check for any available firmware updates for your printer model.
• Follow the instructions to update the firmware if necessary.

3. Perform a Printhead Alignment

• Open the printer software on your computer or use the printer’s control panel.
• Look for a printhead alignment option and follow the on-screen instructions.

4. Perform a Printhead Cleaning

• Open the printer software on your computer or use the printer’s control panel.
• Select the option for printhead cleaning and follow the instructions.

5. Check for Printer Errors:

• If there are any error codes or messages on the printer’s display, make a note of them.
• Refer to your printer’s manual for specific troubleshooting steps related to the error codes.

I hope this helps.

Take care and have a good day.
