Common causes

  • 1Battery pack deeply discharged from long storage.
  • 2Oxidation on the battery interface pins.
  • 3Internal hardware component failure (PMIC).
  • 4Charging cable voltage fluctuation.

Solutions

Quick Diagnosis

If the printer displays ERR-05 and shows a red blinking LED, it confirms the battery communication has failed. Check if it functions while connected to wall power.

Step-by-Step Solution

  1. Remove battery: Disconnect the unit from power and remove the battery.
  2. Clean terminals: Ensure contacts are free of debris.
  3. Test AC power: If the printer runs on AC alone, the battery is the source of the error.
  4. Charge: Insert and charge for 4 hours.

Prevention and Maintenance

Store batteries at room temperature and perform full charge/discharge cycles occasionally to keep cells balanced.

When to Call a Technician

If the unit fails to run even on direct AC power, the internal power circuitry may be failing, requiring authorized repair.
