The Snapscan homepage on http://snapscan.sf.net also mentions that you need at least 1.0.16-CVS. Oops, you're right. It was the snapscan chart that I was talking about and it does indeed say 1.0.16-CVS. However, that labelling system *was* confusing to me and I think my brain just read it as get .16 or newer instead of get newer than .16. I'm an experience unix user and I messed that up... my post was more for the noobs seeing this in the future to not have the headaches I did. Most of your other points are FC3 related, as far as I can tell. It may be a good idea to post these issues on a FC3 mailing list. OK. FC5 will probably have .17 anyways so it's not a big whoop. Thanks.

Hi, I'm new to the list. I just bought an Epson 3490 as it looked possible to make it work with linux and it got good reviews. It's working now, but with 3 hours of fighting... Help for other people trying this in the future: 0. A good site that helped me is: http://www.michaelminn.com/index.php?linux/peripherals.html 1. Someone should change the sane compatibility list to show that it does NOT work as of sane-backends-1.0.16. It should be noted you need CVS or .17 once it's released. 2. It's quite a bit of work for a FC3 user: must rpm -e sane-backends, sane-frontends, xsane and xsane-gimp and then compile/install yourself the first 3 packages from CVS source. 3. Must manually move the 2 hotplug files from sane-be source to /etc/hotplug trees. 4. Must get the firmware file from a Windows install of the scanner and put it somewhere in linux and change snapscan.conf to point to it. File is esfw52.bin in C:\WINDOWS\SYSTEM32 5. *** THE BIG PAIN *** I'm not sure if anyone knows why this happened: It might be FC3 specific. The problem was something in the system (I still don't know what) makes a symlink from /usr/local/lib/sane/libsane.so.1 - libsane-v4l.so.1.0.16. That's totally bogus. If I rm the symlink it just instantly pops back into existence!! Weird! This wouldn't have been a problem, but my /etc/ld.so.conf had /usr/local/lib/sane listed BEFORE /usr/local/lib and so this bogus libsane.so was being used instead of the real one in /usr/local/lib! Reversing the order in ld.so.conf solved the problem. Scanner works great now. If anyone knows WTF is up with #5, let me know. The scanner scans quick and looks good. I did a test at 600 dpi and it looks fine. Someone else reported it looked pixelated? Please email me if this appears to still occur as I want to make sure my scans are perfect. I haven't tried the TPU yet as I don't really need that feature. I'm willing to run whatever tests the devs may want and report back if that would help. Thanks to all the coders for their fine work.

Very good. Can you do some tests, e.g. do all resolutions work? Does the transparency unit work? There seems to be something odd about the geometry calculations for the driver. I.e. when I try to scan a full page, whether I specify the full -x and -y or simply say scanimage, it only gets the first 16.5cm for the width and 22cm for the length rather than the full 21.5cm x 27.5cm (US letter size). In Windows it correctly scans the whole page though. [That being with the Windows software that came with the scanner, of course.] Do you think this is a problem that is related to the firmware, to how SANE talks to the firmware or just with SANE itself? Just so I have a better idea to start looking into this myself - I'd like to have the issue resolved one way or the other before the time is up for returning the scanner... Thank you, Bjorn.

In Windows it correctly scans the whole page though. It wouldn't take 3200 resolution, instead giving the message scanimage: rounded value of resolution from 3200 to 2400 and then giving a scanimage: sane_start: Error during device I/O message. Unplugging and replugging the USB cable was required to do another scan after that. 2400 only gives the scanimage: sane_start: Error during device I/O message and it hangs for a while again. The next step down is 1200 which works fine, albeit slow. I haven't tried the transparency unit yet. The most critical issue thus seems to be that the driver doesn't copy the whole page. Is this something that's easy to fix, is there any way I can help out? Thank you, Bjorn.

Does all this mean that I need to load some firmware onto the scanner before I can use it, or should it work out-of-the-box with the snapscan backend? I'll try the CVS code a little later. Bjorn.

Hi, Does all this mean that I need to load some firmware onto the scanner before I can use it, or should it work out-of-the-box with the snapscan backend? Yes and no. The backend will download the firmware to the scanner automatically (as does the windows driver). See http://snapscan.sourceforge.net for more information. The firmware is only loaded into the internal RAM of the scanner. Once you switch off the scanner it is restored to it's original state. /Oliver

The firmware is only loaded into the internal RAM of the scanner. Once you switch off the scanner it is restored to it's original state. I see. It looks like I had to install the driver under Windows, then. Did a test scan in Windows and it worked. Then rebooted to Linux, and scanimage -L found device `snapscan:libusb:001:003' is a EPSON EPSON Scanner1 flatbed scanner and scanimage ran just fine, both the RPM version and the CVS version from 20050815. I found the driver in c:/WINDOWS/system32/esfw52.bin, copied it to /etc/sane.d and modified the firmware entry in snapscan.conf, and now it works even after rebooting both the scanner and the computer.

I recently got the Epson Perfection 3490 PHOTO scanner. It's connected through USB to my computer running Fedora Core 3, my SANE versions are # rpm -q -a | grep -i sane xsane-0.92-13 xsane-gimp-0.92-13 sane-frontends-1.0.12-4 sane-backends-1.0.15-1.4 sane-find-scanner finds the scanner at libusb:001:003, but scanimage -L just returns without finding anything (No scanners were identified.[...]). I added usb 0x04b8 0x0122 to /etc/sane.d/epson.conf, which made scanimage -L take longer ( 10 seconds) to return the same answer (No scanners were identified). Does anyone else have any experience with this scanner, and/or can tell me whether it is (or will be in the near future) supported by SANE? Any pointers on how I can make it work with SANE is much appreciated. Thank you, Bjorn.

Any pointers on how I can make it work with SANE is much appreciated. I got some infos and a patch concerning this scanner. I'll add support for it to the snapscan backend in the next few days. I'll let you know if the code is in CVS, so you can test it. /Oliver
