The scanner is used, but in great cosmetic and working condition.
There is only one minor scuff on the cover's corner, shown on photo. Otherwise like new.
Comes in original box with all original accessories.
The glass surface has micro scratches from use, but it doesn't affect the scans at all.
They are so thin and hardly visible, I couldn't even make a picture of them. Only visible if you have good eyes and look very closely with a good light and under a certain angle.
Also, the glass has accumulated some dust underneath, especially around edges, which also doesn't affect the scans.
The biggest issue I see is that there are few hardly visible vertical hair lines on the scans, best visible when you make a color scan of a pure white paper in high resolution. Please see the sample of a scanned book page. If you zoom in enough, you'll see few pink and yellow vertical hairlines.
This never really bothered me, especially since I mostly scanned books in black&white. Anyway, I have to let you know and you decide.
After making the scan I found a few dust specs on it, but these can be cleaned. There's always some dust attracted when scanning the books.
You can't find any cheaper in this condition.
Really great tool, I am only selling because I am moving and have to downsize.
