Epson WP-4520 Error OxB3
When you encounter the Epson WP-4520 Error code OxB3 on your printer, it indicates an ink device error. This error message could be caused by various factors such as ink cartridge failure, holder board assembly failure (CSIC or contact failure), main board failure, or cable or FFC disconnection.
One possible reason for this error is a problem with the ink cartridges. Make sure to check if any of the cartridges are empty or low in ink. If so, consider replacing or refilling them. You can also try removing and reinserting the cartridges to ensure they are properly seated.
Another potential cause of this error is a failure in the holder board assembly, specifically with the CSIC (Cartridge Sensor IC) or its contacts. In this case, you may need to contact Epson’s customer support or a professional technician to replace the holder board assembly.
It is also worth checking if the main board of your printer is functioning correctly. If the main board is faulty, it may display the Error code OxB3. Again, contacting Epson’s customer support or a technician will be helpful for further diagnosis and repair.
Additionally, ensure that all cables and Flat Flexible Cables (FFC) are properly connected. A disconnection or loose connection can trigger this error. Carefully inspect the cables and FFCs and reconnect them securely if necessary.
In conclusion, the Epson WP-4520 Error code OxB3 signifies an ink device error. By troubleshooting the ink cartridges, holder board assembly, main board, and cable connections, you can potentially resolve this issue. However, if the problem persists, contacting Epson’s customer support or a professional technician is advisable.
