Duplex color scanning used to work with this scanner, I don't remember
when... duplex lineart works without issues...
Could somebody do some duplex color netscanning tests with there systems?
Kind regards,

This layer should still be optional invisible for the end user. The few experiences I gathered the last days testing the scanner gives me the impression the following features should be added as some sort of filter that can be enable and lies between the driver and the scanadf (sane) output image. By default the scanner scans in duplex mode and scans all input available (no -x, -y or --page-width and --page-height) this should ensures no source data is missed. (this is currently not the case) This data is send to the filter and does the following: 1) recognizes document size 2) removes blank pages (backsides of input with nothing on it) 3) auto rotation and autodeskew extra like to have possibilities: 4) auto color detection 5) auto resolution selection depending on input sizes After this there will be a simple but good usable image that can be used for all other stuff. This output is what I expected when using scanadf without any options on an simple A4 of A8 or C5 input sized source. Yes- it would be nice to have a seamless 'middleware' layer which could clean the output of any sane driver. It need not be completely separate from the actual scanner driver, as they could all use a common external library to provide these features. That might simplify the user interface. Another option is to write a sane 'middle-end', but I'm not sure what form that code (and particularly its interface) might take. If there is anything I can do in the forms like sponsoring or spreading awareness please tell me. I would very much like to see these middle ware layer to become stable and available for all distributions? Is there a SANE developer doing some nice things at FOSDEM 2010 this year? I also would like to add colour balancing as one of the features making background really white, the ScanSnap seems to make backgrounds a bit blueish when doing colour scans. Would it be possible to share the technical datasheet of the chipsets and it's options/registers used to develop the device driver? I am interested in how primitive these chipets are because I for something that can do so little, the price is very high for a mass produced consumer product. The fujitsu chipsets are some of the most advanced available. They have jpeg output, full-speed duplex, USBSCSI, self-calibration, dynamic thresholding, noise removal, intermediate resolution interpolation, etc, etc. If you think this machine is bad, you should try to write a driver for a low-level chipset sometime. One that makes you calculate the motor slope tables and maintain all the per-cell shading info in an external file. That will teach you the true meaning of the word dumb. I am utterly grateful for the current fujitsu driver. I do have some experience with low-level chipset programming and it will indeed get you more humble. There are no publicly available docs for the S1500. It's protocol is very similar to that of old SCSI fujitsu machines, just wrapped in a USB packet, and some additional capabilities added. You can see the M3093 OEM Manual here: http://193.128.183.41/HOME/v3__product.asp?pid=51inf=docwg=0 Thanks, this OEM manual shows a lot of nice information to bad it is not public available for the S1500. There is especially a lot of nice information over what the ADF can handle. It does say it can do automatic page size detection. I still have to be honest that my 130 Euro HP scanner has a more stable ADF input feeder, causing more paper to go in and go out straighter. It is by far not as fast, and had no duplex, but the output quality is the same or even better because of better colour balancing. It can also not scan A8 buy the S1500 also need a lot of manual tweaking to scan different pager sizes without black banners. I added support for the S1500 to my scanadf post-processing systems and fixed some issues that came up when having a fast duplex scanner outputting multiple images at the same time :D http://www.powercraft.nl/pipermail/packages-commit/2009-December/000221.html https://secure.powercraft.nl/svn/packages/trunk/source/pct-scanner-scripts/pct-scanner-scripts-devel/ There will be a new Debian package in a few months after testing the current code for a while. It will eventually be available to all Debian based distributions. There is no OCR output yet because tesseract is not create enough quality yet. Thanks in advance, Kind regards, Jelle

Hi Allan, thank you for taking the time to response at my questions, m. allan noah wrote, on 22-12-09 21:18: # bug02: It seems ADF Back and ADF Front are outputing something that is not on the original paper, only ADF Duplex seem to work here... I would need a sample image. Are you sure you are running libsane 1.0.20? I tried to reproduce the results I encountered yesterday, but the scanner is now responding in a different way. (see the attachment) Did you connect the scanner to a windows machine in between these two tests? It is possible the windows driver updated the firmware... Nope there was no Windows near the machine, I try to live in a windows free zone. However I have not seem the behaviour again. So I am hoping on it just being an anomaly. # bug03: It seems around 15mm of text is missing from the bottom of all pages when trying to scan simple A4 pages. Page geometry: 5096x6600+0+0 please use the page width and page height options to set the actual size of the paper. if you are using a command line program, you should set those options before you set the x/y image size. The datasheet(1) is saying it can scan A4 paper and automatically recognizes document size, is this not supported in the device driver? the 'datasheet' does not describe the hardware, but rather the hardware+windows device driver. Some features, like auto cropping are software only features. This is common. You need a very smart ($1000+) machine to do this in hardware. That said- the git development branch of sane-backends does have a first attempt at a software implementation of these features. The device comes with a fujitsu scansnap carrier sheet to help guide documents through the scanning process. It seems the scanner is designed in a way to never have good scans but just scan the biggest area possible allowed by the size of the input and do all the processing later in the software. So the output of this device is especially messy because it seems intended for post-processing. Is it really that hard to scan A4 paper with a more then 500 Euro scanner? So far I only have been trying to get the basis functionality of the 100 Euro all in one HP scanner that I previous used, let alone get the functionality I really wanted like automatic different size business card scanning. Am I now just bitching and making no sense or is there something wrong? I know I am a perfectionist but I need it for the quality of the work I do. You are overreacting a bit, yes. It is not particularly hard to set an extra page-length option. I could have set the default to A4 length, but I'm in the US :) I can understand the settings being predefined for US Letter. I have no issues with that, but having to manually measure and set the --page-width and --page-height is something I did not expected to be necessary to get a good scan result. Having to predefine this for A4 is still a disappointment but expectable. Having to do the same for every business cards or special sized input papers would become something extreme annoying. # big black bars on the bottom of the pages, unusable for archiving and unprofessional for sending to other business partners big? wow, you are hard to please :) You could try the current development version of sane, and see if the software based cropping and length detection features help. If not, we accept patches... I know I can be demanding, sorry for this, I want to be able to set-up sane based scanner solutions on multiple locations and the usability and features should first reach my quality tress hold levels before I can deploying it. I have the feeling the driver is doing it's job, but the scanner needs an complete additional layer to become productive usable. This layer should still be optional invisible for the end user.

This output is what I expected when using scanadf without any options on an simple A4 of A8 or C5 input sized source. I don't have time any more to do coding myself, but I would really want some advice from you and other sane developer on what it would take to make the above working and available under GNU compatible licensing and compliant

Thank you Allen for taking the time to answer my questions, m. allan noah wrote, on 21-12-09 17:56: I'll admit it is a bit odd, but a few other backends do this as well, so I followed the trend of 'readable' options. I believe there is also a scanner model that has a flat-end extension so, the ADF prefix could make sense then, however back, front, duplex would be my preferred choices. All fujitsu scanners internally consider the 'front' of the paper to be the side which touches the paper tray. Is this not the case for the s1500? Yes the front is the side which touches the paper tray and the beginning seems to be the point where scanning starts. This means you have to turn the paper on top and rotate the front to back before placing the paper in the tray. This is really counter intuitive. Is this hard coded in the firmware of the scanner or something of the device driver? # bug02: It seems ADF Back and ADF Front are outputing something that is not on the original paper, only ADF Duplex seem to work here...

It also requires a firmware upload, is entirely reverse engineered. It has a smaller paper tray and is slower than other fujitsus. Most of the rest of the fujitsu machines (including the S1500) are much smarter, and I actually have documentation for them, and support a huge list of options. Unless you absolutely need the smaller footprint of the S300 (or the ability to run on USB power), I would definitely buy a 'normal' fujitsu. If money is an issue, see if you can still find an S500 or S510, or buy a used or refurbished fi-series machine (fi-5110C, fi-5120C, fi-6130). They show up on ebay quite often... So I got my self a brand new Fujitsun ScanSnap S1500, connected it to my networked saned Linux server, and tried to detect it with one of my sane capable scanadf clients.. but no joy. The other HP scanner was still detected. So debugging started.. :( See the email attachment. It seems the device node for the scanner does not have the correct group permissions set.

How about QA? Why not merge with sane and cups? I would really like to see all hp scanner and printers be merged with sane and cups so there is one system that supports multiple backends. Any thoughts? Best regards, Jelle

Please help, Best regards, Jelle de Jong Hello everybody, After more debugging with strace I discovered that the running command received a SIGHUP [1] singal, I tried all kind of things like wait, nohup, disown to keep the script called by scanadf running, but no luck. [1] --- SIGHUP (Hangup) @ 0 (0) --- Am I correct that your script is called from scanadf and it then receives SIGHUP after some time of running? If yes, did you try disabling bash's standard SIGHUP handling (which is to send SIGHUP also to it's children) trap SIGHUP IIRC another problem can be vanishing filedescriptors, like STDIN going missing. I see that you run some programs in background with nohup. If you want them to run completely independant you could try runnning them with disconnected filedescriptors, like program - - 2- Of course that can be impossible if you need them but depending of how your program works it may be a solution. Regards, Simon Thanks for the hints, I did not try to use the trap or redirections since I think the default behavior is kind of broken. Would somebody be willing to take a look at it? I also have the following question: I created the below project: http://mentors.debian.net/debian/pool/main/p/pct-scanner-scripts/ It is a bash script that wraps all kind of extra functionality to the scanadf tool. Maybe it would be nice if somebody could make scanadf2 or scantool for it as evolution or enhancement of the original tool? Best regards, Jelle de Jong

Kind regards, Jelle Due to the great tip of Allan to check if saned was working if I brought down the firewall, I got a bit further in my debugging. So I took down the firewall and tried to access the scanner on my client. It still did not work while I could not find any alarming things in my logs. I started the debug command to check things and now everything was working. I have no idea what is wrong here... I guess it is something in xinetd and the saned connecting but how could one debug such thing? Please see my attachment for more information and specific command outputs. Any help is appreciated, ps.

Hi Julien, Ok, I flushed out the dll.conf file and only added the net and hpaio lines. cat /etc/sane.d/dll.conf net hpaio When running saned in debug mount everything works fine from the client side.
