Epson L850 Error 0x43
The Epson L850 printer is a reliable and efficient device known for its exceptional scanning capabilities. However, users may encounter the error code 0x43 with the message “SCANNER” displayed on the printer’s screen. This error indicates a Scanner/ADF FB PID lock error, which could be caused by several factors.
One of the possible causes of this error is an encoder failure. The encoder is responsible for ensuring the precise movement of the scanner. A malfunction in the encoder can result in the error code 0x43. Similarly, if the timing belt is not properly tensioned or if there is a tooth skip, it can lead to the error as well. Moreover, a crack in the gear can also trigger this error.
Another reason for the error code 0x43 is a cable or FFC (Flexible Flat Cable) disconnection. These cables play a crucial role in transmitting signals and powering the scanner components. Therefore, any loose or disconnected cables can disrupt the functioning of the scanner, resulting in the error.
Motor driver failure is another potential cause. The motor driver regulates the movement of the scanner and any malfunction in it can lead to the error code 0x43. Lastly, a main board failure can also trigger this error, as it controls the overall functioning of the scanner.
To troubleshoot this error, it is advisable to first check for any loose or disconnected cables. If any are found, they should be securely reconnected. It is also recommended to clean the encoder strip and ensure proper tensioning of the timing belt. In case these steps do not resolve the issue, it may be necessary to seek professional assistance to diagnose and repair the fault.
In conclusion, the error code 0x43 with the message “SCANNER” displayed on the Epson L850 printer suggests a Scanner/ADF FB PID lock error. It can be caused by issues such as encoder failure, timing belt tension problems, gear cracks, cable disconnection, motor driver failure, or main board failure. Troubleshooting steps include checking and reconnecting cables, cleaning the encoder strip, and ensuring proper tensioning of the timing belt.
