<span lang="EN-US">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.</span></p>
<p class="MsoNormal" style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><span lang="EN-US">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 ?</span></p>
<p class="MsoNormal" style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><span lang="EN-US">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?</span></p>
<p class="MsoNormal" style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><span lang="EN-US">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.</span></p>
<p class="MsoNormal" style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><span lang="EN-US">I suppose for instance that when a scanner is scanning a document in a 300dpi resolution, it's speed is constant.</span></p>

<span lang="EN-US">Thanks very much for all your insight.</span></p><p class="MsoNormal" style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><span lang="EN-US"><br></span></p><p class="MsoNormal" style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">

Is it really necessary to remodel the scanner? Alternatively,<br>
you might use a lens/mirror system to project an image of your<br>
large object onto a standard A4 flatbed scanner. You would have to<br>
provide additional lighting for the object, and you would have<br>
to to something to protect your scanner from stray light, but<br>
it should be possible.<br>
<br>
You will, of course, not achieve a greater image resolution.<br>
<br>
