I need 300 dpi for my paintings and drawings works, but I don't found how much maximal dpi has this scanner.

How do I calibrate this scanner to make the scanned document full size? I didn't find anything about this, not even in the manual. Images scanned at A2 size become smaller. How to resolve this? I have already requested this information via email, but no one has responded.

Hallo, kann das Gerät auch im Standalone-Betrieb arbeiten? Gibt es eine Buchwippe dafür?

Hello, could you tell how about drawings? Is it scan accurate? I mean proportions of lines and figures, I going to ask to buy this one for scan old drawings, that are scaled 1:1, but not sure, I tried with professional camera and photo give bad proportions of geometry, that hard to take something close when put in CAD program, but there is chance, that I used wrong fokus and had bad angle ( not sure about 90 degree)

It looks like it would be stupid to buy! I mean, if you do not bother to answer check questions from potential costumers for the last 6 month, how will you react if somebody ever gets a fault?!
I was about to buy this model, but I'll try instead to find a brand who gives a sh*t.
