Epson EcoTank ET-3850 Error 0x61: Carriage Fault

The Epson EcoTank ET-3850 error 0x61 signals a mechanical or electronic lock on the print carriage. When this error occurs, the printer detects that the carriage cannot move from end to end, which is typically caused by a small piece of paper, foreign objects, or dirt on the transparent encoder strip.

  • 4Worn flex cable powering the print head.

Solutions

Diagnóstico rápido

If you hear a loud thumping noise or the carriage attempts to move but halts abruptly, error 0x61 is occurring. Visually inspect the metal rail the carriage slides along to spot debris.

Solución paso a paso

  1. Turn off the printer and unplug the cord to prevent damage to the logic board.
  2. Open the scanner unit and move the print carriage manually from side to side gently.
  3. Clean the encoder strip (the transparent strip with lines) using a very soft cloth slightly dampened with isopropyl alcohol.
  4. Check that no external object is hindering the path.

Prevención y mantenimiento

Never force the carriage while the unit is powered on. Cleaning the encoder strip is essential; a dirty strip confuses the carriage position sensor. Using genuine ink prevents internal leakage that harms optical sensors.

Cuándo llamar a un técnico

If the 0x61 error persists after cleaning the encoder strip and freeing the carriage, the carriage motor might be burnt out or the main logic board is short-circuited.
