Service Error: Internal Sensor Failure (Unspecified)

This error indicates a problem with an unspecified internal sensor. The printer may not be able to perform certain functions accurately.

• 1Faulty or disconnected trailing cable affecting carriage position sensor data.
• 2Malfunctioning Encoder Strip (EES) or its associated sensor, leading to inaccurate carriage positioning feedback.
• 3Defective Media Advance Sensor (MAS) or Media Edge Sensor (MES) preventing proper paper loading or movement detection.
• 4Issues with the Printhead Carriage Assembly, specifically internal sensors related to printhead alignment or drop detection.
• 5Intermittent or complete failure of a specific sensor on the Main PCA (Printed Circuit Assembly) due to component degradation or power fluctuations.

• Printer displays error code 0x00F20001 immediately upon power-on or during initialization.
• Inaccurate or inconsistent printhead alignment, leading to poor print quality or vertical banding.
• Media loading failures, where the printer struggles to detect paper edges or advance the media correctly.
• Carriage stalls or erratic movement, sometimes accompanied by grinding noises, indicating loss of position awareness.
• Printer fails to complete diagnostic tests related to printhead or media handling, often freezing or restarting.
