Epson PX720WD Error 0x4 D
The Epson PX720WD is a highly efficient scanner that helps individuals and businesses streamline their document scanning processes. However, there are times when you may encounter error code 0x4 D Display on the scanner, indicating an issue with the scanner’s functionality. To tackle this problem, it is essential to understand the possible causes and troubleshooting steps involved.
One common cause of this error is an excessive load on the scanner’s Automatic Document Feeder (ADF) FB BS+. This could occur due to an incorrect alignment or a paper jam within the ADF. To fix this, carefully remove any paper jams and ensure that the ADF is properly aligned.
Another potential cause is an encoder failure. The encoder is responsible for accurately sensing the position of the scanning head. If it malfunctions, it can result in error code 0x4 D Display. In this case, it is recommended to contact Epson customer support for assistance and potentially arrange a repair or replacement of the faulty component.
A tooth skip or improper tension of the timing belt can also lead to this error. Inspect the timing belt for any signs of damage or misalignment. Adjusting the tension or replacing the belt if necessary may resolve the issue.
Additionally, a gear crack, cable or FFC disconnection, motor driver failure, or main board failure can trigger the error code 0x4 D Display. These issues generally require expert attention and should be addressed by an Epson technician.
In conclusion, encountering error code 0x4 D Display on the Epson PX720WD scanner typically indicates a problem with the scanner’s functionality. By following the mentioned troubleshooting steps or seeking assistance from Epson’s customer support, you can effectively address the issue and resume scanning operations promptly.
