One of the main reasons that often trigger issues like Epson WF-3640 error code 0x97 is due to internal hardware issues of the printer. Besides, a motherboard malfunction can also lead to the issue. To resolve this, follow the below-mentioned troubleshooting steps:
Turn off your printer and disconnect the printer’s power adapter from the electric socket.
Open the printer access door and check if there is any jammed paper. If yes, grab the paper using both your hands and gently remove it. Ensure that no paper traces are left inside.
Check if the ink cartridge is properly seated. Also, ensure that no dust is present on the printhead.
Close the printer access door and connect the power adapter back to the electric socket. Turn the printer on and check if the issue is resolved.
