Epson WF-C5290BA Error 0x7921
The Epson WF-C5290BA printer may encounter the error code 0x7921, which will be displayed on the printer’s screen. This error is related to the Head FFC (Flexible Flat Cable) abnormal voltage, indicating a potential problem with the printer’s head or main board.
When the Head FFC abnormal voltage error occurs, it suggests that there could be an issue with the connection between the ink head and the printer. This connection is established using the FFC cable, which transfers signals and voltage between the components. If the voltage isn’t within the specified range, it indicates an abnormality.
One possible cause of this error is a failure of the head, where the ink head itself may be malfunctioning or damaged. Another possibility is a failure of the main board, which controls and regulates various functions of the printer. In both cases, the printer may display the error code 0x7921 to alert users of the problem.
To troubleshoot this error, you can try the following steps:
1. Turn off the printer and unplug it from the power source.
2. Check the FFC cable connections to ensure they are secure and not damaged.
3. Inspect the ink head for any signs of damage or blockage. Clean it if necessary.
4. If the issue persists, reset the printer to its factory settings.
5. Consider contacting Epson customer support or a professional technician for further assistance if the problem remains unresolved.
It’s essential to address this error promptly to prevent any disruption in your printing tasks. By following the troubleshooting steps provided, you can effectively diagnose and resolve the Head FFC abnormal voltage error on the Epson WF-C5290BA printer.
