How can we help you?
The MS840 is a plug-and-play laser scanner.  It does not require 
a driver and should be recognized as a generic HID device by 
your computer, similar to a standard keyboard. This allows you 
to scan into any eld that you could normally type into. 
Unitech’s  professional  support  team  is  available  to  quickly 
answer questions or technical-related issues. Should equipment 
issues occur, please contact a Unitech Service Representative
