Solutions

Diagnóstico rápido

Error 02 appears on the screen when the printer cannot maintain a stable power link. If the device only works while connected to AC power but shows the error when unplugged, the battery is the source of the issue.

Solución paso a paso

  1. Extraction: Remove the battery pack.
  2. Cleaning: Wipe the gold contacts with a clean cloth.
  3. Verification: Check for debris in the battery bay.
  4. Charge cycle: Connect to power for a full cycle.

Prevención y mantenimiento

Perform full charging cycles regularly and avoid third-party adapters. In very cold environments, allow the device to warm up before attempting to print to keep the battery at peak performance.
