Step-by-Step Instructions

Step 1 - Installing the software on your computer

Install the software from the manufacturer's website: quantexlab.com/en/download.html
(according to your operating system type and bitness).

Step 2 - Getting the latest firmware for the adapter

Launch the new ScanDoc software on your computer using the desktop shortcut.

Scanner serial number input form

When you first launch the program, a form for entering serial numbers will appear. Enter your scanner's serial number.

If your scanner has serial number s/n: 01230, then enter number 1230.
If you have multiple scanners, enter their serial numbers separated by commas, for example: 25478, 1230.

The program will then automatically download the firmware files from the internet for your scanner.

Step 3 - Putting the scanner into bootloader mode

This is only necessary if you were working with the old software and are now switching to the new one.
If you were already working with the new software, skip this step.
