Epson EP-978A3 Error code OxBO Display on PRINTER: Ink Device Error
When you come across the Epson EP-978A3 error code OxBO on your printer, it indicates an ink device error. This error message primarily appears in situations such as ink cartridge failure, holder board assembly failure (CSIC or contact failure), main board failure, cable disconnection, or FFC (Flexible Flat Cable) disconnection.
One possible cause for this error is an ink cartridge failure. Ensure that you have correctly installed the ink cartridges, and check if they are properly seated in the printer. If the issue persists, try replacing the ink cartridges with genuine Epson cartridges.
Another potential cause of the OxBO error code could be a problem with the holder board assembly. This assembly consists of the CSIC (Contact Image Sensor Controller) or the contacts responsible for communication between the ink cartridges and the printer. In case of failure, it may require professional assistance to repair or replace the holder board assembly.
Additionally, a main board failure might trigger this error code. First, try restarting the printer and ensure that all connections to the main board are secure. If the problem persists, contact Epson support for further guidance.
Lastly, cable or FFC disconnection could be causing the OxBO error. Inspect all cables and FFC connections to ensure they are firmly plugged in. If any connection appears loose or damaged, carefully reconnect or replace it.
It is always recommended to refer to the printer’s manual or contact Epson’s customer support if you encounter the OxBO error code. They will provide you with accurate troubleshooting steps or direct you to a qualified service technician if necessary.
