[sane-devel] Canon ImageClass MF3010
Hi Nathan, If you are willing to do some beta testing, we can try to implement your scanner into SANE. If possible we need a reference scan logfile from Windows. Please use usbsnoop (http://benoit.papillault.free.fr/usbsnoop/) to sniff a complete color sample scan of approx. 5mm x 5mm @ 75 dpi from Windows XP. If you cannot create the reference scan logfile from Windows, I can implement your scanner similar to existing ones next to your scanner's usb product id. Then we'll need some patch iterations while testing.

I believe it's supposed to be supported under the pixma backend. It wasn't detected at all with sane-backend 1.0.23, once I added the product id to udev rules, sane-find-scanner will detect it, but scanimage -L does not. dmesg [ 8764.657596] usb 1-3: new high-speed USB device number 10 using ehci_hcd [ 8764.813796] usb 1-3: New USB device found, idVendor=04a9, idProduct=2759 [ 8764.813810] usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 8764.813819] usb 1-3: Product: MF3010 [ 8764.813826] usb 1-3: Manufacturer: Canon Inc [ 8764.813831] usb 1-3: SerialNumber: 112130031CCB [ 8764.822501] usblp 1-3:1.1: usblp1: USB Bidirectional printer dev 10 if 1 alt 0 proto 2 vid 0x04A9 pid 0x2759 sane-find-scanner found USB scanner (vendor=0x04a9 [Canon Inc], product=0x2759 [MF3010]) at libusb:001:010 found USB scanner (vendor=0x0403, product=0x6001) at libusb:001:007 but still no joy. Does anyone have any info on this scanner?

[sane-devel] Pulstek OpticBook 3800
Hi! I've recently bought Pulstek OpticBook 3800, hoping that it is almost the same thing as 3600, and I wont need much configuring with it. This hopes died when I did sane-find-scanner, it said found USB scanner (vendor=0x07b3 [PLUSTEK INC], product=0x1300 [USB2.0 SCANNER], chip=GL847) at libusb:001:020 and 3600 is GL841 :-( What did I do: I've cloned Genesys_Model plustek_3600_model in backend/genesys_devices.c replaced GENESYS_GL841 with GENESYS_GL847, added correct vendor and product id for this clone in device list there, built and installed it, and also added vendor and product id into /etc/sane.d/genesys.conf Result was the following scanimage makes the scanner move it's head (not always sane, sometimes it tries to move out of device physical limits) and turn the lamp on and off. Scanning goes with turned off lamp, and the result file if always filled with 0x00, even if i put external light source over the scanner. This is my limits of what I can do myself without your help. I did not found any info about how to turn some debugging output (-v -v -v -v -v does not give much information about what sane is trying to do with the scanner) I did not found any guides about how to debug devices in such cases. If you can help me with these question, or even can guide me through the debugging process, this would be great. As I can understand GL847 chip is supported by SANE and we should do calibration and other staff like these... What I should do first?
[sane-devel] HP Scanjet 3000
Is there any way to make an HP Scanjet 3000 work on Ubuntu? Ubuntu does not even recognize a device has been plugged in. Any help would be appreciated. Thanks. -- next part -- An HTML attachment was scrubbed... URL: http://lists.alioth.debian.org/pipermail/sane-devel/attachments/20130418/cb039602/attachment.html
[sane-devel] plustek backend - lamp-switch option
Hi, Am 16.04.2013 08:24, schrieb Gerhard J?ger: Hi, On Sunday 14 April 2013 16:03:49 Alexander Hofmann wrote: [...] Does that mean that the scanner supports scanning with the lamps off? (e.g. to scan negatives)? no. Switching the lamps while scanning is performed by the backend. Indeed, I located the code (calls to usb_LampOn in plustek-usb.c)... If so, how should I use that option? This option is available to provide a way for a possible frontend like XSane for switching on or off the lamp manually for example before doing a scan. Could be interesting when skipping the warmup option - which is in fact only useful for CCD based scanner that hav a CCFL lamp. Ok, so not what I was searching for. Switching lamps off and on during scans/calibration steps when using CCFL tubes might not be the best idea either... Regarding writing a backend, this one could be a starting point http://www.sane-project.org/backend-writing.txt That one helped me out: I was able to add a new option, dark-scan to the plustek backend, that causes the driver to switch of the lampes the moment the scan begins. It works like a charm - digitizing old S/W negatives works, and so does scanning pictures projected by scanner cameras. As the scanner is recording red, green and blue channels one by one, color's not possible of course, except with using filters and scanning the image thrice, witch might produce some interesting results when using IR, I've yet to check that. If there's interest in the change, I could try to provide a patch, although I'm not very familiar of using git... Thanks for the help, Alexander -- next part -- A non-text attachment was scrubbed...
