Solutions

Diagnóstico rápido

Error 0x97 typically locks the printer, preventing any operation. It occurs when a component, often the printhead, draws too much power or fails to send a correct signal to the mainboard. If your machine is stuck, check for physical resistance in the carriage path first.

Solución paso a paso

  1. Total power down: Disconnect all power and data cables from the device.
  2. Physical inspection: Ensure no paper bits or debris are blocking the moving parts.
  3. Hard reset: Hold the power button for 30 seconds while plugging the printer back into the wall outlet.
  4. Printhead check: Inspect the ribbon cables for signs of oxidation or wear.

Prevención y mantenimiento

Avoid pulling the ink carriage manually when powered on. Always use genuine Epson ink to prevent electrical surges or ink buildup on sensitive internal boards. Keep the unit away from dusty environments.

Cuándo llamar a un técnico

If the 0x97 error persists after the manual reset, the printhead assembly or the mainboard is likely damaged. Repair is not user-serviceable in this case and requires professional equipment.
