Hi,
I've been trying another way of looking at things and was wondering whether it would be possible to remove the motor from a scanner but still keep it functional. I know that I can manually start the scanner and place its head into zero position. Is it possible to tell the scanner to scan a 2 meters long surface and therefore to remain on/in scanning position long enough? And then, from the drivers, to obtain a 21,7cm x 200cm jpg ? In most of the scanning software, you can set the exact size of the surface you want to the scanner to scan, by defining a surface that is less than the maximum scanning surface: would the opposite be possible, and tell the scanner to scan more than 21,7 x 29? If that is the case, I could very well use an independently operated motor that I would control to move the scanner head along the surface, at a speed matching the constructor specification. I suppose for instance that when a scanner is scanning a document in a 300dpi resolution, it's speed is constant. Thanks very much for all your insight. 2010/7/14 Ulrich Deiters <ulrich.deiters at gmx.de> > Is it really necessary to remodel the scanner?
