Diagnóstico rápido

The E-01 error indicates the printer has halted all operations for safety. This is a "System Error" requiring a full reboot. If the error appears after an update, it is likely a software corruption issue.

Solución paso a paso

  1. Unplug the printer and leave it for 5 minutes to clear internal board charge.
  2. Ensure the printhead carriage is not physically obstructed by small debris.
  3. Plug the power cable directly into a dedicated wall outlet.
  4. If the printer powers up, navigate to settings and check for firmware updates.
