Epson Artisan 720 Error 0x4 B
The Epson Artisan 720 is a highly advanced scanner that offers exceptional image quality and superior performance. However, it is not exempt from occasional error codes like the 0x4 B display on the scanner, which indicates an error related to the SCANNER/ADF FB BS+ excess load. This error code points toward several possible causes that should be addressed for proper troubleshooting.
One common cause of this error is an encoder failure. The encoder is responsible for providing precise positioning information to the scanner. If it malfunctions, it can result in error code 0x4 B. Another potential cause is a tooth skip or improper tension of the timing belt. The timing belt ensures smooth movement of the scanning mechanism, so any issues with it can trigger error codes.
A gear crack can also lead to this error. If any gears within the scanner are cracked or damaged, it can cause the SCANNER/ADF FB BS+ excess load error to occur. Additionally, a cable or FFC (Flexible Flat Cable) disconnection can disrupt the communication between different components of the scanner, leading to error code 0x4 B.
Motor driver failure is another possibility. If the motor driver, which controls the movement of the scanning mechanism, malfunctions, it can trigger this error code. Lastly, in rare cases, the main board of the scanner may fail, resulting in the display of error code 0x4 B.
To troubleshoot this error, it is recommended to check the encoder, timing belt, gears, cables/FFCs, motor drivers, and the main board for any faults or malfunctions. If any components are found to be defective, they should be repaired or replaced accordingly.
