Epson XP-950 Error 0x4 D
The Epson XP-950 Error code 0x4 D Display on SCANNER is a common issue that users may encounter. This error is associated with the Scanner/ADF FB BS+ excess load error, which typically occurs due to a range of potential causes. Understanding these causes is crucial for effective troubleshooting and resolving the error.
One potential cause of this error is an encoder failure. The encoder is responsible for translating the position of the scanner into readable data, and when it malfunctions, it can result in the error code 0x4 D. Another possible cause is a tooth skip or improper tension of the timing belt. The timing belt is responsible for moving the scanner, and any issues with its tension or skipping of teeth can lead to the error code.
Gear cracks can also cause the error code 0x4 D to appear. If any of the gears within the scanner mechanism are cracked or damaged, it can affect the proper functioning of the scanner and result in this error. Additionally, cable or FFC (flat flexible cable) disconnection can be another underlying cause. If any of the cables or FFCs connecting the scanner components to the mainboard are loose or disconnected, it can trigger the error.
Motor driver failure and mainboard failure are two more potential causes of the Epson XP-950 Error code 0x4 D. The motor driver controls the movement of the scanner, and if it fails, it can lead to the error. Similarly, if the mainboard, which controls all the functions of the scanner, experiences a failure, it can trigger the error code.
To troubleshoot the error, it is advisable to check for any visible damages or loose connections. Restarting the printer and ensuring that all cables are securely connected can sometimes resolve the issue. However, if the error persists, it is recommended to contact Epson customer support or a qualified technician to diagnose and fix the problem.
