I can also confirm that the MP450 still works, and that I believe is a generation 1 machine.

[sane-devel] Status of Avision
Hi Mike, Sorry for the late reply... For the sake of future Avision users scanning the mail archive, I'm going to list the known issues with the backend. ?I've only recently taken over maintenance of the backend, so these are the only two issues I'm aware of: I'm glad someone is doing some work on Avision again. I still have problems with my Avision scanner. I outlined the problem in this message: http://lists.alioth.debian.org/pipermail/sane-devel/2009-September/025343.html The short recap is that I can't scan anything with Linux. The unit does work under Windows. If you need more information or anything else I can do, please let me know. Best regards, Jeroen Eeuwes
[sane-devel] Status of Avision
According you your last post, you ran: $ export SANE_DEBUG_AVISION=7 $ scanimage -l 5mm -t 5mm -x 15mm -y 15mm 2 scanner-name.log scanner-name.png This command will scan a 1cm square area on one page. You might be able to test multiple pages using the -b option. Another thing to try is changing the size of the scan area, since a small area scans perfectly, it would be interesting to know what the boundaries are.

[sane-devel] Status of Avision
Hi Mike, According you your last post, you ran: $ export SANE_DEBUG_AVISION=7 $ scanimage -l 5mm -t 5mm -x 15mm -y 15mm 2 scanner-name.log scanner-name.png I just did a git clone of the sane-backends repository (AFAICR I did that in 2009 too). I ran this command: sudo SANE_DEBUG_AVISION=7 /usr/local/bin/scanimage -l 5mm -t 5mm -x 15mm -y 15mm 2 AV220G-5-15.log AV220G-5-15.png That worked OK. Actually this is an improvement but this didn't work right in 2009 :) Another thing to try is changing the size of the scan area, since a small area scans perfectly, it would be interesting to know what the boundaries are. I increased the size of the -x and -y parameters. That's OK until I use 202 for both the x or y parameter. The results in behaviour are a bit different than last time. Now the units sits idle for a while, it tries to 'eject' a page (even though the page had already gone through the system), it is idle again and then it beeps very loudly (until turned off). If I turn the scanner off scanimage will end without generating a valid png file. It does the same if I put multiple pages in the scanner. It will go through page 1 and 2. Then it will start to pull page 3 in the scanner, but it stop once it is in and then the unit starts beeping. Note, this is all without the -b option. I tried -x 200mm -y 250mm and vice versa but the results were the same. The -x 200mm and -y 200mm work, but I get only about 2/3 of the page. That matches the command of course, 200mm is about 2/3 of the length of an A4. Attached is the log from this (failed) command: sudo SANE_DEBUG_AVISION=7 /usr/local/bin/scanimage -l 5mm -t 5mm -x 200mm -y 250mm 2 AV220G-5-250.log AV220G-5-250.png I tried with -x 20mm and -y 300mm. That worked OK! I had the entire length of the page, but only a small bit. I increased the -x (in large steps) until it stopped working. At 150mm it said Segmentation fault. After a bit of trying I found that -x 120mm -y 300mm works OK, above 120 it will not work. Sometimes it will say Segmentation fault immediately, sometimes the unit will eject a non-existing page and starts beeping. I did not get the -b or --batch command to work at all. That gives the same faulty result: 1 page 'scanned', 1 page 'ejected', the third page stuck and a loud beep until turned off. If scanimage works OK I'll get a readable image file. If it doesn't then I have a file which can't be read. GIMP just says not a valid file, GPicView says Premature end-of-file encountered. Geeqie will show the file, but the image is only shown a bit (depending on the size of the file: sometimes half, sometimes less). What can I try next? ;) Best regards, Jeroen Eeuwes -- next part -- A non-text attachment was scrubbed...

After pulling commit e72c0f548eebfae0171ab8a2e2a74174c1bd96ae, the pixma backend works correctly with my MX850; there is no corruption, even on widths indivisible by 32.

[sane-devel] HP ScanJet G2410
Hi, I am trying to get HP ScanJet G2410 working with SANE, USB-Identification: usb 0x03f0 0x0a01 I've tried following drivers: genesys hp3900 hp4200 hp5400 hp hp_rts88xx hpsj5s Following drivers didn't even list the scanner in xsane: hp5400 hp hp_rts88xx hpsj5s hp3900 hangs during init hp4200 hangs during acquisition of preview genesys always acquired the same preview (left half white, right half black). And the noise the scanner makes during scanning is horrible. Is there anything I can try to help you support this scanner?

[sane-devel] HP Scanjet 8270 / Avision backend / ok but strange issue
Dear all, I've just received this HP Scanjet 8270 (ADF) scanner two days ago and I'm in the process of getting it working with my Debian Testing workstation. As this scanner needs the latest version of the avision backend, I've recompiled the libsane-backends Debian package after having replaced the avision.* files in the source as stated on the avision backend web page. I've now reinstalled the package and the scanner works almost flawlessly for what I've tried up to now (ADF works, gray / color no issue). However, though I own another old Epson scanner which I can use as a regular user, It seems I can only use the new HP as root... No need to say I'm a member of the scanner group... I've tried to locate various information concerning the possibility of specifying users permissions for usb devices but all the information I can find seems to concern old kernels / udev... systems... Is it possible that it is related to the backend itself ??? Any hint ? I haven't recompiled the whole of sane (only the backends), is it a possible source of this issue ? Thanks anyway for the development of the avision backend.

Thanks Dustin for your feedback. The issue of memmove vs memcpy appears in the last phase of image processing, to reduce the scanned line width, in order to get an exact scanned area width, and get rid of the Pixma modulo 32 line width. Il this case, the cropped line is copied above the scanned line, that explains the overlap situation, but the cropped line is always smaller, so no risk of buffer overflow. When the width is an exact multiple of 32, the cropped and original lines are exactly identical. What is weird here, is that the effect of overlap in memcpy does not seem to produce the same effect on different systems ! Looks some systems have memcpy to copy correctly above the original line, but not others. Anyway, the memmove here handles correctly the overlap situation, so this issue should be solved now.
