The available scan area is reported by the scanner. It reports a different area for reflective and for transparent scans.
The Expression 1600/1680 did support transparency scanning of the full size of the glass - most (all?) other EPSON scanners don't support that. The reason is that it's fairly complicated to come up with a light source that can light a large area homogeneously.

Unfortunately I cannot tell the exact reason why (an update to a lib, kernel etc.) In fact scanimage works Ok but any other GUI frontend (xscanimage, xsane and kooka) doesn't work. xscanimage/xsane/kooka take several minutes and finish normally but hardware doesn't work at all and the result image is whole black and no errors (all needed debug flags set) given in console. I have tried: 1. To install old sane/xsane versions but none of them worked. 2. To use the above mentioned not working applications with a fresh start (deleting ~/.sane folder) with no effect. 3. To use the above mentioned not working applications as root - still no effect. I have no "/usr/lib/sane" entry in ld.so.conf I tried to have only one entry in /etc/sane.d/dll.conf for plustek but that does not help either. If you need debug from scanimage and xsane for comparison just tell me.... I have looked at them but found nothing interesting except the missing lines for the MOTOR hardware behaviour... -- PhobosK - A KBFX Team Member -------------- next part -------------- An HTML attachment was scrubbed...

So I wait any news from you or Karl in order to have the chance to use the whole transparency area and avoid the use of Winz for the big x-ray films, Bye Luca -------------- next part -------------- An HTML attachment was scrubbed...

The driver cannot detect the scanner. Any help and advice would be appreciated. L Briscoe
