@venkat1926, Welcome to HP Support Community!
I suggest you perform troubleshooting steps from this document HP Deskjet F4100 All-in-One Printers - Blinking Lights under the section All the lights blink.
If the issue persists, it could be a hardware failure. Please reach out to the HP Support in your region regarding the service options for your printer.
Hope this helps!
