Epson R390 Error OxOC
The Epson R390 printer may display the error code “OxOC” along with various descriptions indicating different issues. One possible error is the CR PID lock error, which suggests an error with the CR (carriage) assembly’s position sensor. This issue may result from a misalignment or misplacement of the CR unit, hindering its movement.
Another potential error is CR encoder failure. The encoder helps to determine the position of the CR assembly on the printer’s main board. If the encoder malfunctions or encounters any issues, it may lead to the error code display.
CR motor failure is yet another possible cause for the error. The CR motor controls the movement of the carriage assembly. If the motor fails or malfunctions, it may prevent the CR from functioning correctly, resulting in the error message.
CR Mechanism overload may also trigger the error. If too much load is applied to the CR mechanism or if it becomes obstructed, it could lead to this error code.
During troubleshooting, it is essential to check if any parts have become detached. This detachment could refer to numerous components within the printer such as cables, connectors, or FFC (Flexible Flat Cable) disconnections. Ensuring all parts are securely connected and attached is crucial in resolving this error.
Furthermore, motor driver failure can trigger the error code display. The motor driver is responsible for controlling the movement of motors within the printer, including the CR motor. If the motor driver fails, it can disrupt the CR’s functionality and prompt the error message.
Lastly, main board failure is a potential cause of the error. The main board acts as the central component responsible for communication and control within the printer. If the main board experiences a malfunction or failure, it can generate the error code.
In summary, troubleshooting the Epson R390 printer’s error code “OxOC” involves investigating possible causes such as CR PID lock error, CR encoder failure, CR motor failure, CR Mechanism overload, detached parts, cable or FFC disconnection, motor driver failure, or main board failure.
