Epson WF-4720-4725 Error 0x0070
The Epson WF-4720-4725 is a high-performance printer that occasionally encounters error code 0x0070, which is displayed on the printer’s screen. This error message typically indicates an issue related to the I/S load position, such as excess speed error, encoder error, or a contaminated encoder scale.
One possible cause of this error is a disconnected or broken FFC (Flat Flexible Cable) that connects the encoder sensor to the printer’s main board. If this cable is damaged or not properly connected, it can result in the error code 0x0070.
Additionally, an encoder sensor failure or a motor driver failure can also trigger this error message. The encoder sensor is responsible for detecting the position of the printing head as it moves across the page, and any malfunction in this component can lead to the error code.
Another potential cause is a contaminated encoder scale. The encoder scale is a strip with fine lines that assist in measuring the printing head’s position accurately. If this scale becomes dirty or contaminated with ink, it can cause errors in position detection and lead to error code 0x0070.
Lastly, in rare cases, the error may be attributed to a main board failure. The main board controls various operations of the printer, and if it malfunctions, it can result in the I/S load position excess speed error.
To troubleshoot this error, you can start by checking the FFC and ensuring it is securely connected. If it is damaged, a replacement might be necessary. Cleaning the encoder scale with a soft cloth or a specialized cleaning solution can help resolve contamination issues. If these steps don’t solve the problem, it’s advisable to contact Epson customer support or a professional technician who can diagnose and repair more complex issues such as encoder sensor failure, motor driver failure, or main board failure.
