  • 3Cell degradation: Natural battery wear from intensive use.
  • 4Defective cable: High internal resistance in the cable preventing correct charging.

Solutions

Quick Diagnosis

The error is visualized via flashing status LEDs when you attempt to send a photo to print from your mobile device.

Step-by-Step Solution

  1. Connect charger: Use a wall charger providing at least 5V/1A.
