[sane-devel] Can't get Canon MP360 working
Hi Martin,
Your scanner seems to use the same command set as MP700/MP730 but there are
still some differences, e.g. the command sequence for reading image data, the
length of the interrupt packet (16 instead of 8 bytes) etc. You can derive
your code from pixma_mp730.c in the pixma backend. (Please download the
backend from http://home.arcor.de/wittawat/pixma. I haven't updated CVS yet.)
Add your scanner to the device list at the end of pixma_mp730.c:
DEVICE("Canon PIXMA MP360", 0x263c, 1200, 636, 877, 0),
The backend should detect your scanner now. You may try scanning a _small_
area but don't expect that it'll work. Unfortunately, the source code is not
documented. If you have any questions, just ask! :-)
Regards,
Wittawat

[sane-devel] Re: Best Scanner for Sane
In response to the question of what I'm planning to scan,, it's mostly going to be text for OCR, but there will probably be a photo or 2 from time to time. So I'm trying to figure out the best scanner to do that with using sane. Thanks, Terrence
[sane-devel] Dell 1815dn
Hi, I discovered today that a binary SANE (and CUPS) driver for Linux is provided for Dell 1815dn multifunction printer/scanner/copier. Since it is provided by the manufacturer I presume that it supports the full set of functionality but I don't have one of these devices so I can't confirm for definite. cheers, Jon == Jon Chambers = http://www.jon.demon.co.uk, 020 8575 7097, 07931 961669 =
[sane-devel] Problem with sane plustek_pp
Hi, From the sane-backend 1.0.17 version to 1.0.18, I have a small problem with my scanner plustek p12. Although it scans images correctly, the carriage of the scanner does not return, after scan or pre-scan. This is truth as for slackware 10.2, updated from current, as for Fedora Core 5. Doing the downgrade for the version 1.0.16, the scanner comes back to works correctly. Someone has a solution for that? -- []s, Flavio J. M. Lopes flavi...@wnetrj.com.br

SANE2 could require that the frontend support jpeg, and that could become the default for the 'format' option. allan > > Yours, > -- "so don't tell us it can't be done, putting down what you don't know. money isn't our god, integrity will free our souls" - Max Cavalera From terren...@ak.net Tue Aug 22 17:57:51 2006 From: terren...@ak.net (terren...@ak.net) Date: Tue Aug 22 17:59:19 2006 Subject: [sane-devel] Best scanners to use with SANE?

I cannot help you in IRC but I'm interested in your driver. If the protocol is similar enough, perhaps you can reuse the code of the pixma backend. What have you done so far? Have you already captured some USB traffics? If so, can you upload the log files somewhere in the internet? I could try to modify the pixma backend so that you need to add only protocol specific codes and don't need to worry about SANE API for the present. Regards -- Wittawat Yamwong Hannover, Germany
[sane-devel] Error when reading from Fujitsu fi-5120c
I'm using Ubuntu 6.06 with all the latest updates and Sane backend 1.0.18 compiled from source along with Xsane .0991. When I try to scan using scanimage or xsane either as root or as normal user I get the following error. "Error during read: Error during device I/O." I've read just about every instruction on setting up Sane and so far I can't get it to work. I did get it to work once, but then it stopped. I believe I manually changed the usb permissions. I've tried to figure out the hotplug stuff, but so far I've failed at everything. Can anybody tell me what I'm doing wrong or not doing?
Re: (ÈðÐÇÌáʾ-´ËÓʼþ¿ÉÄÜÊÇÀ¬»øÓʼþ)Re: [sane-devel] Image Compression doesn't support in SANE protocal
Yes, xsane can save file in a compressed format. But before that we must decompress the data from scanner and then transfer it to xsane and then xsane compress the image So we can't use the compressed data from scanner directly, then the scanner's speed is slow down. - Original Message - From: "Ren?

Well that stinks as you lose a lot of detail with the lossy jpeg decompression. Maybe let's add the JPEG frame type rather soon (even in SANE 1) and let's add an IR (infra red) frame specification on the way as good film scanner deliver for dust and the-like removal. Yours,
[sane-devel] Image Compression doesn't support in SANE protocal
I found no image compression support is added in SANE. When scanning with high resolutions such 600 x 600 dpi and uses color scan, the result image will be very large! So many scanners support compress transfer:scanner compress the image data and transfer compressed data to driver. In SANE the images transfered between backend and frontend are strict limited.I think it' better if SANE add some file transfer type like TWAIN. -- next part -- An HTML attachment was scrubbed...
