Solutions

Diagnóstico rápido

The error E-1 is marked by grinding noises or the carriage remaining stuck at one end of the rail. It is a clear warning sign of a mechanical constraint.

Solución paso a paso

  1. Turn off the printer and disconnect the power cable.
  2. Gently move the carriage from left to right to check for smooth operation.
  3. Wipe the metal carriage rod clean with a dry, lint-free cloth.
  4. Check that the ribbon cartridge is installed correctly and not obstructing the movement.

Prevención y mantenimiento

Applying a tiny amount of synthetic oil to the carriage rod every six months is recommended. Always ensure the printer path is free of debris to extend component life.

Cuándo llamar a un técnico

If the error E-1 remains after cleaning the rails, the motor belt or the carriage motor itself may be failing, requiring professional repair.
