On the results, I was already my old Epson scanner went far beyond my needs (I do that digitizes paper documents, I have another scanner for negatives and slides). There, 4800 dpi, is well beyond what we need to reproduce a paper document (printers rarely go beyond the resolution of 600 dpi, unless you want to enlarge the details of a postage stamp ).
LED technology eliminates warm-up time.
The dust removal software works when the dust is on clear areas ... but not on very dark areas.
The scanner not out JPEG images (8 bits) even if the analysis is done on a broader range of light. We can make things better by going to the histogram, correcting the limits and the curve and see ... but we can not zoom in visualization but only viewed on a large screen (4K if possible).
This scanner can also be used via Photoshop / Import / extension WIA / which has some automation (recognition of the size of the image) but treats only the output image into 8 bits and no opportunity to go tinker the settings or to make an exit in TIFF mode on 48bits.
In terms of analysis with great color depth is below what was my old Epson 1640 scanner (which allowed to go tinkering raw images in TIFF mode), even if it wins the scanner Plan congestion, consumption, resolution and scanning speed.
If you only have standard documents to be processed, or if you need simple corrections, that's good. If you want a more pointed work, for example on old documents that you want to emphasize certain details ... will go upmarket. Still, for the price, it's good.
