Epson WorkForce-840 Error OxB3
The Epson WorkForce-840 printer may encounter an error code OxB3, which is indicated on the display. This error code signifies various issues related to the ink device and can be attributed to ink cartridge failure, holder board assembly failure, main board failure, cable disconnection, or FFC disconnection.
One possible reason for the error could be an ink cartridge failure. This means that the printer may not be able to recognize the installed cartridge or there might be an issue with the ink flow. In such cases, it is recommended to remove and reinstall the cartridges properly. It is also essential to ensure that the cartridges are genuine and compatible with the printer model.
Another cause for the OxB3 error is a failure in the holder board assembly, specifically the CSIC (cartridge chip) or contact. The CSIC is responsible for communication between the cartridges and the printer, and any malfunction can result in an error. Checking for any physical damage or debris on the contacts and cleaning them may help resolve the issue.
In some cases, the error may arise from a main board failure, which controls the overall functioning of the printer. If this is the case, professional assistance or contacting Epson customer support is recommended to diagnose and resolve the issue.
Additionally, cable or FFC (flat flexible cable) disconnection is another potential reason for the OxB3 error. It is advisable to inspect the connections, ensuring that they are properly seated and free from any damage. Reconnecting or replacing any faulty cables or FFCs may resolve the issue.
In summary, the Epson WorkForce-840 OxB3 error code can be attributable to ink device, ink cartridge, holder board assembly, main board, cable, or FFC issues. Troubleshooting steps such as reinstallation of cartridges, cleaning contacts, checking cables, or seeking professional help can assist in resolving this error and restoring the printer’s functionality.
