Delivery by Amazon as always fast.
Connection and installation: Windows 64bit 8.1 quickly and easily.
The configuration of the basic settings with the optically very easy (or objectively) designed Canon software worked without any manual or other search within minutes.
Operation: Sensible scanning speed, practical one-touch keys, acceptable noise levels. Scan results as expected convincing. If required extensive configuration options.
Conclusion: I am completely satisfied with 120. For document-heavy scanning operation highly recommended. Also test scans of original images to make a good impression
