Silly me, it wasn't "almost white" but rather a valid scan of the scanner's background! Managed not to check the actual page is in place, sorry for being *that* stupid that day... Retested as of RELEASE_1_0_24-296-g0655b05 and these are the results with a USB2-connected crop of Canon devices: MF8540Cdn: scanimage OK, xsane OK (75/150/300/600, colour/bw) (at least "Good" by me) MF6140dn and iR1133if: scanimage/xsane OK _BUT_ only once, sort of (might be "Basic", don't know if this passes for git) Now there's a problem with 6140 and 1133 that looks like this: - scanimage produces a file (which is fine); - second scanimage in a row hangs; - xsane hangs too when trying to preview/scan; - turning "remote scan" off and on is not enough; - turning the device off and on (with subsequent selection of scan mode plus "remote scan") helps; - scanimage would hang the same after xsane; - several consecutive scans using a running xsane instance are OK (e.g., different density). 6140 also exhibited weird behaviour at 600dpi (the sound's also different from 75/150/300 which scanned just fine): the head might have been hitting the edge for a second or two with the result being gray bands along the scanning direction at the end of the file, I've uploaded a (8Kx5K) sample here just in case: http://fly.osdn.org.ua/~mike/tmp/sane-pixma/Canon-MF6140dn-xsane-600dpi.jpeg 1133 didn't hit that (the 600dpi sound is also different) but the image quality suffers from some kind of a "cellular" effect, see http://fly.osdn.org.ua/~mike/tmp/sane-pixma/Canon-iR1133iF-xsane-600dpi.jpeg (300dpi and lower are fine though). Again, 8500 had neither of these problems for me now -- never got stuck whatever scanimage/xsane/scanimage I did, the image wasn't distorted, the head didn't hit anything. At least so far. :) Thank you! -- ---- WBR, Michael Shigorin / http://altlinux.org ------ http://opennet.ru / http://anna-news.info -- sane-devel mailing list: [email protected] http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/sane-devel Unsubscribe: Send mail with subject "unsubscribe your_password" to [email protected]
