Hello everyone,

I recently encountered an issue with my Epson WF 7840 printer. It keeps showing an error message saying head id input. I have tried troubleshooting but cannot seem to fix the problem. Has anyone else experienced this issue before or know how to resolve it? Any help or suggestions would be greatly appreciated.

Thank you in advance for your assistance.
