Epson WF-7012 Error 0xB4
When using the Epson WF-7012 printer, you may encounter an error message displayed as “0xB4.” This error code indicates an ink device error related to ink cartridge failure, holder board assembly failure (CSIC or contact failure), main board failure, or cable or FFC disconnection.
One possible cause of this error is an issue with the ink cartridges. Ensure that the cartridges are installed correctly and securely. Try removing and reseating the cartridges to ensure a proper connection. It is also recommended to check if the ink cartridges are low or empty. Replace any empty or low ink cartridges to resolve the issue.
Another potential cause is a failure in the holder board assembly. The CSIC (chip on the cartridge) or the contact between the cartridge and the printer may be faulty. In this case, try cleaning the contacts on both the cartridge and the printer using a soft cloth or cotton swab with alcohol. If the problem persists, it may be necessary to replace the holder board assembly.
If none of the above steps resolve the issue, it is possible that the main board of the printer has failed. This requires professional assistance and a replacement of the main board to fix the problem.
Lastly, ensure that all cables and FFC (Flexible Flat Cable) connections are firmly and securely plugged in. Disconnect and reconnect all cables to ensure a proper connection.
If the error code 0xB4 continues to persist after attempting these troubleshooting steps, it is recommended to contact Epson customer support or a qualified technician for further assistance in resolving the issue.
