Changing target_code makes a difference (just to make sure my

Hello again.
Considering I wasn't able to play with gamma values in code, I took
sample scan images with a calibration sheet for all combinations of:
target_code = { 0x, 0x1000, 0x2000, ..., 0xe000, 0xf000 } in
descending order
resolution = { 75, 100, 150, 300 }
I uploaded the images to the following URL:
http://blog.alvarezp.org/files/scan-hp3670/calibration/
The 300 dpi scans are bigger, of course, but I found different scan
results for different dpi. I wonder if this is just a cheap scanner.
Anyway, I find 0x4000 to have the best value to have no solarization but
the higher the dpi, the darker the images.
While trying to fix the images in Gimp with the Levels and Curves tool I
find that green is more sensible to low light so its 0 point should be
moved to about 15/255 to prevent the shadows to come out greenish. Also
it needs a gamma of about 1.20 to balance the midtones out.
Blue needs a gamma of about 0.80. Red is ok.
Hope this helps.
Hello,
many thanks for your work. Once I fixed an intermittent issue in
LiDE 210 head parking, I'll use all these information to improve HP3670
color scan quality.
Regards,
Stef

However, you were right, the image quality has problems. Using target_code = 0xe000, the currently coded value, I get a bluish and saturated image. I tried lowering target_code across multiple values down to 0x4000. The lower the value, the better the quality but the darker the image.

This is, two small vertical correctly white-balanced sections are noticed at the left and right extremes. For example, at 0x8000, the image is not saturated anymore, and the image is way better white-balanced overall. However, the image is noticeably darker image (75% of the histogram with typical white at 55% luminosity).

At 0x4000, I don't get bluish stripes and perfect white-balance, but it results in only half of the histogram. I tried tweaking the o value (offset?) but I didn't seem to find any kind of pattern, except that if I set it too high I get badly colored stripes, so I just left them at their original values. Thanks again. Hello, the offset shouldn't be touched. For some undocumented reason the ASIC needs it to have the shading coefficients match the right pixels. target_code is giving the desired target value for white.

I'd like to correct myself. Please take my previous message with a grain of salt (or disregard it altogether). I'm noticing that xscanimage is behaving differently than scanimage, regardless of whether I recompile both sane-backends and sane-frontends or just sane-backends. I noticed this because xscanimage is not affected when target_code is changed (and after a make make install), but scanimage is. I need to find some ground on this. Apparently scanimage *is* regenerated when sane-backends are recompiled. So far, I have repeated some of the tests with scanimage only and target_code seems to be too high for my taste. 0x8000 seems like a lot better value. I'm still testing though.

Hi. I'm trying to get my HP Scanjet 3670 under Linux. The scanner works (it scans and all) but the scan has some color distortion. I confirmed the scanner works: here is a comparison of a section of a scanned image in both, Windows and Linux: http://blog.alvarezp.org/files/scan-hp3670/scan-hp3670-win7.jpg http://blog.alvarezp.org/files/scan-hp3670/scan-hp3670-linux.png The scan is a black and white section of a creased document. Even the problem itself is very unstable. Sometimes the whole page is distorted, sometimes only gray shades are. *Once* in my 40-like attempts the output was acceptable but I could not reproduce this success case. I noticed, though that solid strong colors are usually not distorted. I wanted to find out if this was an introduced bug, but I could only compile as back as 1.0.22 + 2 commits and it failed too. Before that, there is a V4L compilation blocker that prevented me from going further back. I tried looking at the code but I realized I understand very little (near to nothing) about how a scanner works. Is this a SANE bug? What can be done to make it properly work? Thanks.

Can you raise genesys debug trace level and run scanimage -L again ? export SANE_DEBUG_GENESYS=255 export SANE_DEBUG_GENESYS_LOW=255 export SANE_DEBUG_GENESYS_GL646=255 scanimage -L 2probe.log Then send the log. You can compress it to get the attachment smaller. Regards, Stef

Since I will be building a new Fedora 14 environment (Amahi.org), with a vanilla Fedora 14 install, on different hardware (just got it in today, need to assemble it) and will hook the scanner to that, I'll wait and see how that goes. Thank you Kasper PS actual scanning with the TRUST does not work, although it is recognized by scanimage -L by the regular user, but that is some other matter, did not try it with the Live Fedora 14 -- next part -- An HTML attachment was scrubbed...

Basically, the process is to record USB logs of the scanner working under windows, then process them to extract commands and register settings, then modify the genesys_gl646.c code to handle it the same. There is some documentation at http://stef.dev.free.fr/sane/genesys/index.html . The C code involved is not high, all you'll have to do some modification of existing code. There is allready an device description of the 3670c in genesys_devices.c . To do a quick test, you can uncomment (remove the '#' at the start of the line) the usb id of your scanner in genesys.conf (which is usually located at /etc/sane.d), then try to use it from scanimage. It should be detected and I expect it to fail during warm-up. Regards, Stef Hello Thanks for the reply! I made some USB-logs with USB Snoopy and tried to decode them with the decode.sh script, but the resulting file is always empty.

[sane-devel] HP scanjet 3670 why there's no suport?
Hi guys this is my first mail. well, i have this scanner and it's still not supported (there have mail in mai archive about genesys backend from 3 years ago!), so i'm into an intersitng situation. My first question is why this backend does not support my scanner. And my second question is what can i do to help the developement of the backend (since for instance i can start as tester i also can learn a bit of C and the SANE patterns of backends and under a more experienced programmer do something. Actually i'm a java programmer, but i have some time (sunday's midnigth, :D) and really want to scan my old photos without buy a new scanner. Oh, about the thread (http://lists.alioth.debian.org/pipermail/sane-devel/2003-November/009360.html), how can i help these guys? is there some code available for now? BTW: thanks guys for a project like it: i had used (for example) an LiDE20 and it worked really perfect.

Hi, I have a hp scanjet 3670 and noticed there isn't support for it. I am a programmer but not very experienced (only 2 yrs of hobby game-programming C++ C and asm). Are there any efforts for supporting this scanner? My only os now is suse linux 9.0. So now I cannot use it :( I would like to help but I fear I am not skilled enough / dont have the time.

Hi Great Job! I know that Hp is not producing all the chipset, but in fact if we can know who is this 3rd party would be a first step... After it will be better of course if we can have an agreement with them and have the doc... thanks for your investigations Mike Sanjay Chigurupati wrote: Hi, I tried contacting HP too. Had met Bdale garbee at Linux Bangalore meet. he said he would try to see if he could help. will send him one more e-mail and see if it works. also tried contacting one of the R D people.

Hi, 1. Is there any usbsnoopy log published on-line in the Internet for the HP3670 and/or HP2400 models? 2. Preview scan will be enough for a initial analysis. Does the scanner work after the preview scan then using usbsnoopy? 3. You said you dont' receive anything in the log, but does the scanning software reveice any image? 4. Does the scanner head move? Thanks in advance. Adrian P.J. Mickael Profeta wrote: Hi, sanjay.chigurup...@lntinfotech.com has a HP scanjet 2400 and it seems to be the same driver.

At least I don't remember anyone posted a link to code or a website for that scanner. If that doesn't happen some weeks after the first announcement, this usually menas that the project is dead. But I like to be surprised otherwise :-) Anyway, even if someone worked on this project, you could still try to write a backend for any of the other unsupported scanners. The list is so long, you shouldn't have trouble to find one :-) Bye, Henning

Hi, Mike is also working on the scanner driver. I am working on the version for scanjet 2400c, which seems to use the same driver as scanjet 3670 c. Maybe we could co-ordinate. I e-mailed directly but for some reason it bounced off ur id.

Hi It seems that we are now at least 3 to be interested to write a driver for 2400/3600 hp scanjet series. I can organize a bit the group if you want, creating an ugly but functionnal web page, a mailing list if you thing it can be usefull and in the future, when we have a bit of code a cvs server... Tell me if you find it usefull For the time, I think we should try to get as much information as possible. I try with hp with no valuable answer (always answer that it is not the good service) If someone wants to try and to get some specification that can help... If not I think we should try to get some log of the usb activity under windows and try to understand what is going on... Then we may start writting a piece of code. I cc sane devel list, If someone is interesting to join, just tell. If someone more used to create driver has some advices, don't hesitate to say... Best regards Mike

Where do I have to begin from?

Or when you have a website describing your efforts or even code so we cann add a link to it. Don't hesitate to ask questions. Bye, Henning

Hi there is also an Elite MT ram chips but I do not take the number, can provide it if it can help. the number on the EliteMT chipset is: EliteMT (100MHz) M1B416256A DZC1HF2GJ I don't know of anyone. First you should check if the USB descriptors look similar to one of the other HP (or other) scanners. SOme information about backend writing is on our homepage. After forcing the scanner module to recognize the scanner, I test the hp_scan.c programm in the scanner.txt doc of the kernel, but with no reponse of the scanner. then amble% scanimage -L device `hp4200:/dev/usb/scanner0' is a Hewlett-Packard HP-4200 flatbed scanner but when I try to run xsane: host/uhci.c: uhci_result_control() failed with status 4c [c13ee0c0] link (013ee062) element (013ef240) 0: [c13ef240] link (013ef270) e0 Stalled NAK CRC/Timeo Length=7 MaxLen=7 DT0 E ndPt=0 Dev=2, PID=2d(SETUP) (buf=088db9a0) 1: [c13ef270] link (0001) e3 IOC Active Length=0 MaxLen=7ff DT1 EndPt=0 Dev=2, PID=69(IN) (buf=) scanner.c: ioctl_scanner: control_msg returned -110 May this means that the driver would be near th hp4200 one? And that I can use it as a starting point? The windows .inf file seems to say that the driver is the same than the one for 2400 series and I see that someone was interested to write a driver for 2400c. Is there something already done? We may get in touch to work together... Bye, Mike

After forcing the scanner module to recognize the scanner, I test the hp_scan.c programm in the scanner.txt doc of the kernel, but with no reponse of the scanner. Well, I would have been surprised if that had worked. That program is only for the older hp scanners (those that are supported by the SANE hp backend). If it had worked, you could have used the hp backend. then amble% scanimage -L device `hp4200:/dev/usb/scanner0' is a Hewlett-Packard HP-4200 flatbed scanner The hp4200 backend is not included in SANE. If I remeber correctly, it detects any HP scanner so that doesn't mean taht it's supported by that backend. scanner.c: ioctl_scanner: control_msg returned -110 I'm not really surprised :-) May this means that the driver would be near th hp4200 one? And that I can use it as a starting point? May be possible but I don't think so. hp4200 is an old backend and that would mean they use the old chipset again. It's a LM9830 parport chipset and a PV8630 parallel port-USB bridge. The windows .inf file seems to say that the driver is the same than the one for 2400 series and I see that someone was interested to write a driver for 2400c. Is there something already done? We may get in touch to work together... Everything I know is in our lists. Just contact the person mentioned there. There is also a similarity reported to the 2300 series, but I don't know if that's really the case. Bye, Henning

Hi I just bought a HP scanjet 3670 scanner and discover that it is not supported under linux... I do not have many new infomations than those already written in the page http://www.sane-project.org/unsupported/hp-scanjet-3670c.html I can just add what is written on the chipset: 26-00204-00A 0310FGGSH-10 there is also an Elite MT ram chips but I do not take the number, can provide it if it can help. I am very interested in writting a driver for this scanner, so if you can help me start and tell me if somebody has already done something or not I will be very glad helping and trying to write the driver. I will appreciate any informations and helps Sincerely Mickael
