Solutions

Diagnostic

The E-01 error appears when the status LED blinks constantly. Check if the tape is centered in the support and the flap does not block the reader sensor.

Step-by-Step Solution

  1. Remove roll: Open the compartment cover and extract the label roll.
  2. Clean sensor: Using a soft, dry cloth, clean the optical paper sensor located at the base.
  3. Reinstall: Insert the tape ensuring the label edge sticks out of the output slot.
  4. Reset: Close the cover and press the feed button once.

Maintenance

Avoid using low-quality generic labels, as excess adhesive can contaminate the optical sensor. Perform a printhead cleaning every 3 rolls using an original cleaning kit.

When to call a technician

If the E-01 error persists after sensor cleaning and testing with a new roll, the main board likely isn't reading the sensor signal.
