I bought a Noritsu LS-600 but it did not come with any software. What is the best way to acquire it?
You can download an old version (6.5) of the twain drivers and software on the Facebook group: “Noritsu Scanner Users”
The most recent version (7.0 TWAIN for Windows 10 and EZ Controller 6.7 for Windows 10) is available directly from Noritsu. Note that you will have to create a business account with them to buy it.
