[sane-devel] OT: list for discussing scanners in general ?
Is there a list for discussing the scanners ? For example I'm looking for a scanner that will do a sheet size of 12 x 18 -pete
[sane-devel] Proposed patch for scanimage in sane-backends-1.0.22
Does the backend for your scanner have a wait for button option ? Thats what I use, just wish my scanner had a jack on the back that let me plug in a foot switch. I'm marking off the days till the resellers warranty runs out so I can add one myself. On Sun, Jun 26, 2011 at 3:58 AM, Yoann Seeleuthner yogos2 at gmail.com wrote: Hello, I would like to suggest a patch to add a new option to scanimage. The idea is to allow user to sleep scanner for a time between two scans in batch mode. I did this patch because I wanted to scan a book manually, and batch mode was too fast (not enough time to turn page), whereas a script looping on normal mode was too slow (at least 6 seconds between two scans with my scanner). So this patch add an option (--batch-delay=INT) that sleep scanimage for INT seconds. This patch have been generated on sane-backends-1.0.22 with diff -cr sane-backends-1.0.22-old/ sane-backends-1.0.22/ patch.diff I hope you will accept it. Best regards.

[sane-devel] 90% off topic - color / gray test strip
I was thinking of having a strip on each side of the scanned documents, one for color and one for gray-scale but I'll admint it is a bit overkill. I've been looking at the different IT8 targets. I'll go with getting a Kodak one. It seems it varies quite a bit. but the price is reasonable. If anyone else is interested two URLs http://www.colorwiki.com/wiki/Test_Images and http://www.colorwiki.com/wiki/Kodak_IT8_%28Q60%29_Targets http://www.computer-darkroom.com/it8cal/it8_page_1.htm http://www.computer-darkroom.com/gamma/gamma_1.htm another source of targets http://www.targets.coloraid.de/ -pete On Tue, Jun 14, 2011 at 6:37 AM, m. allan noah kitno455 at gmail.com wrote: Do they really need to be strips?

[sane-devel] Gt-30000 and epkowa - Was Fwd: sanner still jogs - more buffering ?
My goal is something close to the advertised speed (8.058 seconds per page). I would be happy with say 10 seconds which is 24% slower. Would be OK at say 12 seconds which is almost 50% slower. Will 15 to 17 seconds work, yes. but 85% to 120% slower then advertised really hurts when ones ability to win contracts is based on ones reputation. It is a pity the electronics in the GT-3 are a bit 'old'. What would make this pretty much the perfect scanner would be a new board with 1-2 GB of RAM and a 1,000 MB/s Ethernet interface. Today building a dedicated controller costs no more to have 1 GB then 128 MB. The last design I did using a single commodity DDR-2 (or 3) memory module plus its connector cost less then 512 MB of non commodity memory. 1,000 MB/s Ethernet today is basically free. The only thing I would change in the scanner deck is from a CFL to LEDs. Call it the GT-3E5 (GT-30) and Epson would have a winner. -pete PS Many years ago I worked for a company under Seikosha and the mechanical part of our product was made by Epson.

Let me add to what I said Will 15 to 17 seconds work, yes. but 85% to 120% slower then advertised really hurts when ones ability to win contracts is based on ones reputation. I was asked to come up with a solution to scanning documents. I 'sold' the idea of using Linux and the GT-3. I selected the GT-3 based on two things, the first from talking to users for their opinion of reliability, my personal experience with Epson scanners and finally on the published specifications for performance I'll toss in that Epson (at least the scanner group) supports Linux via Sane. 10 vs 17 seconds may not sound like much, but when one is looking at over 100,000 documents it adds up pretty fast.

[sane-devel] Fedora 15epson2/scsi doesnt work but Fedora 11 - updated does
Olaf, I will give the Epkowa backend a try next (on a side note the URL in the sane documentation is 404) what I've done in the mean time is to download various versions of the sane backends and configure/make. here the results so far .22 - same results as the one from the Fedora distribution .21 - same .20 - works. This is the same version I have on the 'working' PC. -pete On Mon, May 30, 2011 at 5:13 PM, Olaf Meeuwissen olaf.meeuwissen at avasys.jp wrote: Pete Lancashire pete at petelancashire.com writes: CSI, Epson GT-3 backend epson.

[sane-devel] Fuji Lanovia C-550.
yep, thats why my offer for this thing is only $100. Be one of those projects with the goal of someday finding either some internal docs or a Mac with the code and dongle.

[sane-devel] sane over the net .. backend ?
I have a Epson GT-3 on a Fedora 11 box. running xsane it has what looks like all its features, for example the ADF can be duplexing. I've just set up saned on that box. The client I'm using is Linux Mint 9 (Ubuntu under the covers), it 'see' the GT-3 just fine but many of its features are not available, and the ADF eject does not work. Hoping this is a 'operator' error. -pete
