Report downloader for battery

Saved a battery report online? Use this on the device that is connected to the printer: type the 4-digit reference number and download the A4 report or the receipt for the Epson printer.

  1. Type the 4 digits
  2. Pick the control number, type the serial
  3. Download and print

The report can be downloaded once. After a wrong control number or serial the page locks, and after repeated failures the report is deleted.
