Service Error: General Internal Hardware Failure

This is a general critical hardware failure that cannot be specifically identified. It indicates a major problem with an internal component.

• 1Malfunction or failure of the Main PCA (Printed Circuit Assembly) due to component degradation or power surge.
• 2Failure of the Carriage PCA, responsible for controlling printhead movement and ink delivery, often due to electrical shorting or overheating.
• 3Defective or failing Power Supply Unit (PSU) unable to deliver stable and sufficient power to internal components.
• 4Corruption or malfunction of the printer's firmware, leading to incorrect hardware initialization or operation.
• 5Failure of a critical motor (e.g., carriage motor, paper axis motor) or its associated encoder strip/sensor, preventing proper movement.

• Printer fails to power on or powers on but immediately displays the error code without further operation.
• Printer attempts to initialize but carriage remains stationary or moves erratically before displaying the error.
• Unusual noises (e.g., grinding, clicking) coming from internal components before the error appears.
• Control panel becomes unresponsive or displays garbled text/graphics.
• Printer continuously reboots or cycles through power-on sequence without reaching a ready state.

1. 1

   Turn off the printer and unplug it. 2. Wait 5 minutes, then plug it back in and restart. 3. If the error persists, service is required.
