Easy. It makes sense.

Now I have here even my two cents :)
After my old scanner component of a "multifunctional product" and no automatic document feeder has, I knew that the scanning of larger quantities of paper can develop into a sporty and time-consuming action.
So a second device was needed!
Not as a rough block, but a space-saving, stylish yet robust device ...
(All this is the Canon DR-C125)
Delivery was agreed to without much need to scroll through the manual, I was able to quickly install the software on my computer and connect the camera ready.
The scanning software is also relatively simple:
it can be Useful things set, such as simplex or duplex scanning (ie double-sided setting will be scanned in seconds), detection of blank pages, straightening a crooked sheet feeder (which virtually never in my several hours first paper Annihilation Session occurred!)
The scan results can then arrange (saving space) as a PDF file and their quality + expression are as good to designate.
Conclusion Therefore:
great invention for those who want their yellowed paper files say goodbye.
Fully mature technology, very good (and fast) results.
The high purchase price will hopefully pay off in high longevity !!!
