I apologise for my previous message which was not enough clear.
In fact, it seem's that if I do a 2400 dpi scan which does not work, then the following 3200 dpi scan are bad. But it works again if I restart xscanimage. But for me the 16 bit depth doesn't work. If I try to open the file with gimp, the following message is displayed : PNM : invalid intensity maximum value Patrick.
