Epson ET-4750 Error 0x21
The Epson ET-4750 is a highly efficient all-in-one printer that offers exceptional performance. However, it is not uncommon for users to encounter certain error codes, one of which is the Error Code 0x21 displayed on the scanner. This error message indicates a specific issue with the scanner/ADF ALD PID, more specifically an excess speed error.
The ALD motor, responsible for moving the scanner and Automatic Document Feeder (ADF), may encounter a failure, leading to this error code. Additionally, a motor driver failure or a disconnection in the cable or FFC (Flexible Flat Cable) can also trigger this error.
Troubleshooting the Error Code 0x21 requires some simple yet effective steps. Firstly, ensure that the scanner glass and ADF are properly closed and securely in place. If not, gently close them. Next, turn off the printer, disconnect the power cord, and wait for a few minutes. Then, reconnect the power cord, turn on the printer, and check if the error persists.
If the problem prevails, the next step is to inspect the cable and FFC connections. Make sure they are firmly connected without any disconnections. In case any disconnections are found, carefully reconnect them to their respective ports.
If the error code still persists, it is advisable to contact Epson’s customer support for further guidance and assistance. They will provide expert advice and may suggest additional troubleshooting steps or arrange a repair if necessary.
By following these troubleshooting steps, users can effectively address the Error Code 0x21 displayed on the Epson ET-4750 scanner, ensuring seamless printing and scanning experiences.
