  • 1Printhead communication fault.
  • 2Ink seepage on mainboard.
  • 3Drive mechanism strain.
  • 4Voltage fluctuations.

Solutions

Diagnóstico rápido

If the 0x69 appears on your screen, the internal controller cannot communicate with the printhead unit. Avoid opening the printer while plugged in.

Solución paso a paso

  1. Full disconnect: Turn off and unplug for 15 minutes.
  2. Internal inspection: Ensure the carriage moves freely.
  3. Direct power: Connect to a wall outlet.
  4. Restart: Re-initialize the printer.

Prevención y mantenimiento

Keep the printer dry and in a dust-free environment. Use only the recommended ink to avoid clogging the internal sensors that could lead to error codes.

Cuándo llamar a un técnico

If the 0x69 error is persistent after a cold boot, the printhead flex cable or the head itself is likely defective.
