The Epson WF-7725 is a high-quality printer known for its exceptional performance. However, like any electronic device, it can encounter errors from time to time. One such error is the 0x4B error code displayed on the scanner. This error is related to the Scanner/ADF FB BS+ lock, indicating an issue with the scanner function.
The most common cause of this error is an encoder failure, which refers to a problem with the sensor that detects the position of the scanner.

To troubleshoot this error, there are a few steps you can follow. Start by turning off the printer and disconnecting it from the power source. Carefully check the timing belt and gears for any signs of damage or misalignment. Ensure that all cables and FFC connections are securely plugged in. Additionally, clean the encoder strip, which is a long, transparent strip located near the scanner’s carriage.
If the issue persists after these initial troubleshooting steps, it is recommended to contact Epson customer support or a qualified technician. They will have the expertise to diagnose the problem accurately and provide appropriate solutions. It is important to refrain from attempting any advanced repairs if you are not experienced in handling printer components.
