Solutions

Diagnóstico rápido

The error E-205 appears when the printer attempts to move the ribbon but the sensor does not register rotation. This often happens when the ribbon has come loose or the cartridge is incorrectly seated in the print head holder.

Solución paso a paso

  1. Remove ribbon: Open the top cover and carefully remove the existing ribbon cartridge.
  2. Visual check: Verify that the ribbon sensor gear rotates smoothly without obstructions.
  3. Install consumable: Insert a new original ribbon, ensuring the fabric is taut and correctly aligned.
  4. Print test: Run a test print to validate that the sensor detects proper rotation.

Prevención y mantenimiento

Avoid manually refilled inks, as excess lubricant can contaminate optical sensors. Clean the cartridge area with mild compressed air each time you replace the consumable.

Cuándo llamar a un técnico

If the error persists after testing with two different cartridges, the internal ribbon sensor may be miscalibrated or damaged.
