![]() ![]() The only solution that I could find involved copying /usr/lib64/sane into /usr/lib/sane. Because I have no scanner problems with my working version (17.1), it seems logical that the problem occurs because of changes in 17.3. If you’ve tried all these things and still have a problem, we’d really appreciate it if you’d send a Problem Report.Ĭlick here to find out how to Submit a Problem Report. I upgraded from 17.2 to 17.3 and encountered a problem attempting to get simple-scan to recognize my HP 5740.If youre using a USB Scanner, try using a different USB cable or port. If you’re still getting stripes with transparencies, make sure nothing is blocking the small rectangular calibration area on the glass. Make sure your scanner is plugged in and turned on before you start VueScan.If you’re getting stripes, try re-doing the “Scanner | Calibrate” command.The latter suggestion worked, as I reported after trying it. One suggestion given was to install Vuescan another was to install a Windows XP virtual machine and run the scanner in it. If you still can’t scan transparencies, make sure the cable from the lamp in the scanner lid is plugged into the back of the scanner and that the cover is off the lamp in the scanner lid. 1 Back in October I asked for help because Canon does not have a Win 7 driver for my LiDE 50 scanner.If you can't scan transparencies, try the x32 version of VueScan. Try a newer (and preferably shorter) USB cable. If you can’t scan transparencies, try the x32 version of VueScan. Try turning your scanner off and back on again and rebooting your computer - then run VueScan again.Try a newer (and preferably shorter) USB cable. 1 Back in October I asked for help because Canon does not have a Win 7 driver for my LiDE 50 scanner.Try turning your scanner off and back on again and rebooting your computer - then run VueScan again.Try running VueScan and use the “File | Default options” command - then see if the problem goes away.Make sure you’re using the newest version of VueScan (check /rebates/&.com252fmac-computers252f34ruq-when-try-open-vuescan-says-scanner-not.I really liked RawTherapee for my DSLR scans and it even has a Film Negative plugin but at the moment it only works on true RAW files, not what vuescan calls "raw file" (I understand this will be possible in next RT version though).Here are some things you can do to solve problems with VueScan: I know others suggest to get the RAW file out of vuescan and continue with another software, but I don't really have good options on Linux. I would have hoped that there was some option to keep the inverted image but without introducing this compensation based on film type. I don't really like to play around with this potentially destroying the quality of a specific film type. If that fails, reinstall the scanner using the Minolta software. If the 'device manager' still shows a yellow triangle, right click and select 'properties' and see if there is a better driver available. On the other hand, this seems like introduces some kind of compensation to account for a typical density distribution of B&W films (vuescan says most films are similar to that of T-Max, which I'm not sure is really true). Once the computer registers the scanner properly, you seldom have to repeat this process. One problem with this is that it is difficult to choose a CI value that works for all images. In fact, the documentation explicitly states that at this point it is best to select T-MAX 100 and then play with the CI (contrast index) options available to get a reasonable histogram. I initially followed some recommendations about using "generic color negative" but the blacks and sometimes the whites really go out of the histogram and get clipped, so I don't think that is the right approach. I still have color correction set to "none" (as this also modifies the curve). ![]() ![]() However, I found out (and confirmed) that there's a very sensitive step that completely alters the look of the image, which is the part where you select film brand/type/etc. I excercised the "lock exposure" workflow and also found that (for my Minolta Dual Scan III at least) it seems it is better to scan in 48RGB (instead of 16bit grayscale, which seems to only choose one channel) and let vuescan convert to gray in software. Last night I decided to experiment a bit on vuescan on older B&W negatives as I always feel very unsure about the process to get a "decent" image. ![]()
