[sane-devel] RS232 Scanner
Hi, I'm working on getting a RS232 scanner working on Linux. I see that Sane has some support for serial port scanners but not much. The scanner is attached to a POS system for retail sales and runs RHEL5. Unfortunately, I have no documentation for the scanner, I'm not even sure of the brand. There's a logo on the front which is 'G' followed by a globe symbol, followed by 'T' so it could be 'GOT' or 'GT'. There does not appear to be a model number although there is an identification place which is written in Chinese. I have a compiled diagnostic application (no source code) which can control the scanner and I have tried logging the system calls using the 'ltrace' command, so that I can figure out the protocol. I have tried writing a program to mimic the diagnostic application which sends the same commands to the serial port but the scanner does not respond. Does anyone have any expertise in RS232 scanner protocols? All my searching on the web reveals results for barcode scanners which appear to work very differently from image scanners. As a final note, I am trying to use the scanner for OMR - the diagnostic application returns an array of data relating to the marks entered on a slip of paper - if that is any use. Also, I can attach the log file of system calls made by the diagnostic application if that will help anyone. Any help would be greatly appreciated. Thanks, Dan Scott

i have quite a bit of omr experience, and have done a bit with rs232 in the past, but never scanners. do your logs show the actual data being passed? if so, i think your first effort should be to extract image from logs. allan On 7/30/08, Dan Scott danieljamesscott at gmail.com wrote: Hi, I'm working on getting a RS232 scanner working on Linux.

Hi, I think it's a bit simpler than that. The diagnostic software shows an array showing the marked boxes. Here's what I get form the diagnostic software when I scan a slip: Please select: Ticket count: 1 ticket data len=52 .. 1 2 3 4 5 6 7 8 9 0 A B C D .. 1 2 3 4 5 6 7 8 9 0 A B C D 1 * * * . . . . . * . * * . 21 . . . . . . . . . . . . . 2 . . . . . . . . . . . . . 22 . . . . . . . . . . . . . 3 . * . . . . . . . . . . . 23 . . . . . . . . . . . . . 4 . . . . . . . . . . . . . 24 . . . . . . . . . . . . . 5 . . . . . . . . . . . . . 25 . . . . . . . . . . . . . 6 . . . . . . . . . . . . . 26 . . . . . . . . . . . . . 7 . . . . . . . . . . . . . 8 . . . . . . . . . . . . . 9 . . . . . . . . . . . . . 10 . . . . . . . . . . . . . 11 . . . . . . . . . . . . . 12 . . . . . . . . . . . . . 13 . . . . . . . . . . . . . 14 . . . . . . . . . . . . . 15 . . . . . . . . . . . . . 16 . . . . . . . . . . . . . 17 . . . . . . . . . . . . . 18 . . . . . . . . . . . . . 19 . . . . . . . . . . . . . 20 . . . . . . . . . . . . .

but is this diag software output post-processed by the pc? if you have logs of the data in flight, and there is no image, then you dont need sane, you need a standalone app. allan On 7/30/08, Dan Scott danieljamesscott at gmail.com wrote: Hi, I think it's a bit simpler than that.

[sane-devel] RS232 Scanner
Hi, Thanks for your comments. I don't think that there is an image - the log file for the ltrace output is only ~40kb. I think that the scanner is returning the array and there is no post-processing by the diagnostic application. The scanner is also capable of returning an image of the scanned file. So I was hoping that I would be able to use sane to communicate with the scanner and work out what is happening. I was thinking that I would eventually need a standalone app - but I could use Sane for the image part of the scanning. Maybe even use/develop a backend for this scanner?

[sane-devel] CX6600 problem solved
Hi all, sorry this is such a long post.
It was a problem but I fixed it before asking for help by swapping the
usb connection back to the old USB 1.0 port Anyhow in case you might
be interested below is what I was going to send.
I still don't understand why /proc/bus/usb is empty though.
In the end either my usb2.0 card is damaged or the PCI bus cannot
handle it (It was made before PCI-E)
Thanks for all your efforts

I've got scanner problems with my Epson CX6600 attached to an old
Pentium II with a 200 watt power supply and I'm beginning to think
that I might have exhausted the physical capabilities of the machine.
Originally it had a 6GB disk and a CDROM. Also a USB 1.0. I now have 2
disks 80 40 GB, a dvdrv+- and cdrw+-, 2 ethernet cards (only one in
use so far), a USB 2.0 card (to which the CX6600 is attached).
My operating system is grml (http://grml.org) updated to Debian
unstable for many packages including the sane ones. Grml runs xinetd
and this is the appropriate entry in /etc/xinetd.conf and it looks
sound
service sane-port
{
socket_type = stream
protocol= tcp
wait= no
user= saned
group = saned
server = /usr/sbin/saned
server_args = saned
disable = yes
}
The problem is that the scanner hangs with the LCD reading
Scanning... when the scanner lamp has completed its action. This is
what I've investigated for myself before coming here:
# sane-find-scanner
found USB scanner (vendor=0x04b8 [EPSON], product=0x0813 [USB2.0

Bus 001 Device 001: ID :
# scanimage i.pnm
#
So scanimage seems to exit 0 as a success but the scanner LCD hangs
with the message Scanning... I think that this tells me it has not
received a terminate signal although scanimage has exited with one.
The supposed image file is not readable.
# head i.pnm
P4
# SANE data follows
848 1169
... and lots of blurb
Peculiarly the kernel process shows nothing in the usb bus - so I
don't understand how lsusb works.
# ls -l /proc/bus/usb
total 0
The only relevant message from the system log is this:
# tail /var/log/syslog
Jul 30 08:35:00 grml kernel: usb 4-4: usbfs: interface 1 claimed by
usblp while 'scanimage' sets config #1
But that is no help as this message was there when the scanner did work.

[sane-devel] RS232 Scanner
Hi, 2008/7/30 m. allan noah kitno455 at gmail.com: So I was hoping that I would be able to use sane to communicate with the scanner and work out what is happening. backwards. you have to work out what is happening, _before_ you write the sane driver :) Not quite. I was hoping that the scanner would already work with sane. :) at least partially. Then I could get the basic protocol from the code. do you have windows drivers for the image scanning part? if so, i would use a usb-serial converter and benoit's usb sniffer to get a log, and see if you can extract the image data. No, unfortunately I have no documentation/driver other than this diagnostic application. I'm thinking I'll have to figure out the manufacturer and ask them for protocol documentation. It's a shame there's no standard for serial port scanners! Would avoid a lot of work. Thanks for your comments. Dan

Hello!! We have maded a big frame (lika a door) with rail for the ccd's of the scanner. We take some test with the motors. Now we need try two scanner in parallel. It's possible to setting xSane to start two scanner at same time? How? What i need about softwares? I'm on Ubuntu with xSane ecc. Thank a lot for responses.

We also think about a Frankenstein-scanner made of various parties other scanners (A4 course). We need to do so because we not have a budget large. We have also seen this site http://www.artila.com/, there are some controller and engine, the controller contains a small linux and may be (as we understood) used to control engine or electrical appliances. We plan to use it to manage the engine scanner. you think we can use for our project? Is possible to build a mega-scanner with part of A4 scanner? There's an engineer among yourselves? i have a mechanical engineering background, and like any good engineer, i am telling you, keep it simple. use a camera- they are cheap, have a much greater depth of field, are designed to work with ambient light conditions, the list goes on. the scanner idea is art, not engineering. allan -- Email.it, the professional e-mail, gratis per te: http://www.email.it/f Sponsor: Aggiorna la playlist del cellulare con tante nuove suonerie!

[sane-devel] help with profiles
I am new to the Linux world (via Ubuntu 8.04) and like most of what I am experiencing. However, there is a lot to learn in the transition from Windows XP. I was pleased to see that Ubuntu came with Xsane preloaded and that Xsane fully supported my Epson Perfection 2450 Scanner. However, I soon learned that the fact that Xsane supports it does not mean it automatically finds and loads all the associated software it needs to properly run the scanner. I have been posting questions to the Ubuntu mailing lists and looking over the Xsane web site (appreciate the documentation), and discovered that I am supposed to add something called printer and scanner ICM profiles. My printer is an HP 722c deskjet printer. When I follow the instructions on the website, I got to preferences, setup, and copy, and then have to type in the model number of my printer. I then try to browse for the ICM profile and it takes me nowhere useful that I can find. Ubuntu easily found and mounted my peripherals, including the printer and digital camera. However, I am stuck on getting the scanner to work properly. If I ignore a lot of error messages, I can get it to scan a color image in grayscale, but that won't do the trick. I find that I use a scanner for a lot of what I do on a computer. Is there any way I can easily find the profiles Xsane seems to be asking for? Gordon Small
[sane-devel] help with profiles
you should not need anything other than libsane and xsane installed to get scans. the ICM type stuff is useful for color correction, but is not required to get color scans. try this at the command line: scanimage --mode=color test1.pnm and then look at test1.pnm and see if it looks correct. that will cut xsane out of the loop. allan On Wed, Jul 30, 2008 at 2:00 PM, gordonsmall User gordonsmall at bellsouth.net wrote: I am new to the Linux world (via Ubuntu 8.04) and like most of what I am experiencing.

In the past I have sniffed some serial protocols using Mark Russinovich's PortMon: http://technet.microsoft.com/en-us/sysinternals/bb896644.aspx It doesn't work when they directly access the serial port, though. About the scanner not responding to your replicated commands, could it be that you need to change some of the other serial lines (DTR, RTS)? Daniel

A SANE image is a rectangular area. The rectangular area is subdivided into a number of rows and columns. At the intersection of each row and column is a quadratic pixel. A pixel consists of one or more sample values. Each sample value represents one channel (e.g., the red channel). Each sample value has a certain bit depth. The bit depth is fixed for the entire image and can be as small as one bit. Valid bit depths are 1, 8, or 16 bits per sample. If a device's natural bit depth is something else, it is up to the driver to scale the sample values appropriately (e.g., a 4 bit sample could be scaled by a factor of four to represent a sample value of depth 8). So the answer is yes. Hope this helps, -- Olaf Meeuwissen, LPIC-2 FLOSS Engineer -- AVASYS Corporation FSF Associate Member #1962 Help support software freedom http://www.fsf.org/jf?referrer=1962

that case, the configuration files are below /usr/local/etc/sane.d/. If you want them where your distribution put them, you need to rebuild and reinstall after running ./configure --sysconfdir=/etc Hope this helps, -- Olaf Meeuwissen, LPIC-2 FLOSS Engineer -- AVASYS Corporation FSF Associate Member #1962 Help support software freedom http://www.fsf.org/jf?referrer=1962

Looks like in the end there was mistake on my end, that didn't let sane detect my scanner. You see, with my distribution two packages are shipped: sane-backends and sane-backends-libs. Before installing sane from sources i did remove sane-backends but didn't do the same with sane-backends libs. Since sane is installed from sources to a different place (/usr/local), rather than the one from package, libs from rpm stayed perfectly intact and it was them that sane was using when looking for scanner, not recompiled ones. So i removed sane-backends-libs and my scanner got perfectly detected. At least we're getting somewhere. But of course scanner won't scan. Ok, it would scan, but it's output doesn't resemble whatever was scanned - it looks just like red stripes on black background. And there are problems with scanner head. Usually before scanning scanner head goes couple of centimeters forward and adjusts light intensity, then goes back and starts scanning. With sane, it does the same, but with a louder sound, which makes me a little worried. And most importantly, scanner doesn't know where to stop. When scanning from XSane sometimes scanner head just goes about one centimeter and stops, beepeing strangely. Sometimes it goes 2/3 of scanner length, and it does so *very fast* with an odd sound, then finishes scanning and goes back with same speed and sound. When running scanimage from commandline, the sound and speed are quite the same as normally (by 'normally' i mean like it works on proprietary system with proprietary drivers), until scanner head bumps into the wall. When you stop it there, and look at the resulting image, about 2/3-1/2 is filled, so scanner head has a rather long way to go. Any ideas what to do with that? -- Igor G Novikov septagramm at gmail.com -- sane-devel mailing list: sane-devel at lists.alioth.debian.org http://lists.alioth.debian.org/mailman/listinfo/sane-devel Unsubscribe: Send mail with subject unsubscribe your_password to sane-devel-request at lists.alioth.debian.org

'quality calibration' ON and OFF doesn't change a thing. Scanning in windows is fine, no issues. Any ideas? Thanks in advance.

- replace linux specific ppdev code with sanei_* equivalent functions. - make sure the code is still compatible with latest SANE releases (in this case, it is better to check code from Debian's sane-backends-extras, for which Julien has made a great job making the code at least compilable for latest releases) and follows SANE guidelines for inclusion into the repository. - test on actual hardware to make sure it still works after changes (would require help from community if the developer lacks hardware to test). And longer term tasks for better support: - implement calibration support - improve support for large width scans at high resolutions (the windows driver does this very well with little backtracking even on a emulated Bochs VM). - implement support for some Vivid Pro II variants (not based on the same chipset as my device). - implement support for the rare USB variants I could even offer access to the geniusvp2 project at SourceForge for those interested on helping, but I think it is much easier to just download the latest code from CVS (or even better, take the code from Debian's sane-backends-extras package), and work based on it. Then I should simply deactivate the project at SF, since it would make no sense anymore to keep it after inclusion in SANE repository. Anyone interested? Regards, -- Anderson Lizardo

$ scanimage scanimage: sane_start: Document feeder out of documents scanimage: Received signal 15 scanimage: Trying to stop scanner scanimage: Received signal 15 scanimage: Aborting There may be a status of some kind I can check from SANE without crashing before I try scanning but I haven't found it yet. Is there any way to prevent this from killing my server in the meantime or is catch the biggest gun I have for that? Thanks, - Ian
