When scanning with the debug options enabled, there will be a file=20 called plustek-pic.raw Can you send me the files from your gentoo-box and from the IXP? Please scan something which contains some colors and or stripes to see the mismatch. =46rom the logs you've currently sent I can't see any problems. The regis= ter settings seem to be okay, even the calibration steps seem to work on the two boxes. The only difference I see is, that on the gentoo box, scanimage seems to get serveral lines in one transfer, while on the IPX each line is transfe= rred. The next odd thing is, that on the IXP you'll get some 0 data, but why? You'll probably send me all the raw files you get from one scan... Gerhard
