Epson WF-3640 0x97 error

Apparently cleaning with a wet towel or wet wipe is needed.

Don't be tricked into downloading antivirus software from some web sites that are actually malicious.

Example of cleaning suggestions:

"Before you buy a new one. Clean the rolls and ink holder in the printer with a wet wipe or wet cloth. Start it without the ink cart, it should then ask you to insert it. Insert it then and it will go through the new ink routine. I did that twice and it fix the error.
It seem like one of the nozzle might be clog up and clean and forcing the printer to push more ink out will clear the clog."
