Epson WP-M4525 Error 0x4 D
The Epson WP-M4525 is a versatile all-in-one printer that offers excellent performance, but just like any other device, it can encounter issues. One of the error codes that users may come across is the 0x4 D Display on SCANNER. This error is often accompanied by the message “Scanner/ADF FB BS+ excess load error” and indicates problems related to the scanner’s functionality.
There are several potential causes for this error. Firstly, an encoder failure may be the culprit. The encoder is responsible for accurately determining the position of the scanner, and if it malfunctions, it can lead to the error code 0x4 D. Another possibility is a tooth skip or improper tension of the timing belt. If the timing belt is not correctly aligned or has skipped one or more of its teeth, it can cause the scanner to generate this error.
Additionally, a gear crack within the scanner mechanism can also trigger the excess load error. This occurs when one or more gears within the scanner assembly become damaged or cracked, preventing smooth operation. A cable or FFC disconnection is yet another potential cause, as the scanner relies on these connections to communicate with the main board.
To troubleshoot and resolve this error, several steps can be undertaken. Firstly, checking and ensuring that all cables and FFC connections are securely fastened is essential. If the connections appear loose or damaged, they should be replaced. Additionally, inspecting the gears and timing belt for any signs of damage can help identify the cause.
However, if the error message persists, reaching out to Epson customer support or a qualified technician is recommended. They can provide further assistance and evaluate if a motor driver failure or main board issue is to blame. With their expertise, they can guide you through the troubleshooting process or suggest repairs or replacements if necessary.
