[sane-devel] Epson CX7400 support

Is there a schedule that would tell me approximately when 2.10.0 will be released? I can't really give a date but we're aiming for first half of this month. The epson backend seems to have trouble with a number of all-in-one devices, AFAIK. I have taken a look at it in the past, comparing to the epkowa backend (part of iscan), but couldn't quite put my finger on it. FWIW, you can use the epkowa backend just fine with scanimage and xsane. Is there a tutorial/howto or something to that effect, which would tell me how to do this? I don't see an option in scanimage parameters where I can specify a backend. Do I need to change the sane config file, instead? All you have to do is install iscan and pick a device that mentions the epkowa backend. If you comment the epson backend out in dll.conf, there is no need to pick one. If you leave the epson backend enabled, XSane will show you a little dialog where you can pick the device. You'll see something like epson:003:004 epkowa:003:004 Oh, BTW, the iscan packages are available from http://avasys.jp/ and some distributions include it in their list of packages, openSUSE for example.

[sane-devel] BRIGHTNESS / CONTRAST controls
Le Monday 05 November 2007 21:42:47 jazz_johnson at verizon.net, vous avez
?crit?:
I've been debugging my hs2p backend and have a question about
BRIGHTNESS/CONTRAST controls.
Following the ibm, bh, and sp15c backends, I initialized a SANE option
OPT_BRIGHTNESS in
init_options()
{
s-opt[OPT_BRIGHTNESS].name = SANE_NAME_BRIGHTNESS;
s-opt[OPT_BRIGHTNESS].title = SANE_TITLE_BRIGHTNESS;
s-opt[OPT_BRIGHTNESS].desc = SANE_DESC_BRIGHTNESS;
s-opt[OPT_BRIGHTNESS].type = SANE_TYPE_INT;
s-opt[OPT_BRIGHTNESS].unit = SANE_UNIT_NONE;
s-opt[OPT_BRIGHTNESS].constraint_type = SANE_CONSTRAINT_RANGE;
s-opt[OPT_BRIGHTNESS].constraint.range = s-hw-info.brightness_range;
s-val[OPT_BRIGHTNESS].w = 128;
}
where struct SANE_range brightness_range = {
1, 255, 1 /*min,max,quant*/
}
since the IS450 has a brightness range [0,255] with 0 being an alias for
the default value of 128 (the midpoint of the odd interval [1,255])
I also defined an analogous OPT_CONTRAST for the contrast function
under the Enhancement Group.
When I bring up Xsane, though, I have two brightness controls, one under
the Enhancement Group with the interval [1,255] labeled Brightness,
and the other under the main Xsane window with the interval [-100,100] with
a Sun symbol for the brightness control. The Xsane contol works with the
Preview window and the Histogram window. I also have analogous dual
controls for contrast, with the Xsane control (labeled with a contrast
symbol) working with the Preview/Histogram windows.
I obviously just want one brightness control and one contrast control. I
don't care whethor the range is [-100,100] or [1,128] or [0%,100%], just
so long as when I set my window parameters I translate to [1,255]
Are BRIGHTNESS/CONTRAST predefined somewhere?
When I reference s-val[OPT_BRIGHTNESS].w am I referencing a value
in the range [-100,100] or [1,255] ?
Hello,
Xsane has a software contrast and brightness correction (the ones in
the -100,+100 range). It also provides a software gamma correction. All these
are independent from the backend and work on the scanned data after they have
been received.
They can be turned off (from the configuration pane in prefrences
menu), so
only the controls implemented in your backend would be used.
Regards,
Stef

It (iscan) doesn't upload firmware for the CX7400. Moreover, firmware uploads would be lost when you power-down the device (long enough). I'm curious as to how you installed and removed iscan. My current best bet is that the epkowa backend is still found in a place where SANE finds it, typically in /usr/lib/sane/, and epkowa.conf is still on the system as well. If you installed with `rpm -U` and removed with `rpm -e` everything ought to be gone after removal. Maybe you're using a less common, as in one we don't test with, distribution and things didn't go as they were intended to. Let me know what distribution you're using and how you installed and removed iscan. Were there any messages by any chance? Also, what device names do you get with `scanimage -L`? If there's any that start with 'epkowa:' the backend's still there somewhere.

[sane-devel] Plustek module problem
I think replug means taking the plug out and putting it back. This how I have configured. I have in plustek_pp.conf [kernel] device /dev/pt_drv option warmup-1 option lOffOnEnd-1 option lampOff -1 In dll.conf I have commented everything else, but plustek_pp. I have no /dev/pt_drv, I have none of the other numbered ones either.

Which device do you miss? You should try and use the plustek_pp backend with the parport_pc and pp_dev modules... - Gerhard
[sane-devel] Plustek scanner problem
I got the module loaded and scanimage -L gives: device `plustek_pp:/dev/pt_drv0' is a Plustek 9636T/12000T flatbed scanner But no graphical frontend finds it. Jarmo Outinen
[sane-devel] Brother 210C scanner/fax/printer help
Hi Everyone On the Sane.org site there are instructions to contact Dmitri Katchalov regarding work with Brother drivers. I was not able to contact him. I would like to begin trying to reverse engineer Windows only devices for use in Linux. I thought I would practice with my unsupported all-in-one printer/scanner/fax. I have a feeling this might not be the easiest place to start. Does anyone know if there are specific issues with the Brother line? Any guidance you can provide before I get started would be great. Thanks in advance for your time-Patrick

Hello, reading the SANE Docs, I found that it is possible to set up the Environmental variable for a larger buffer size: SANE_SG_BUFFERSIZE, I have my RICOH_IS420 scanner hooked uo to Fedora core 6 and it is working well, I just want to set up the variable to a larger size ,but I don't knoe how??, which files need editing ??

You can set environment variables from a shell, i.e., a command line window and start a Sane frontend from the _same_ shell, like so: export SANE_SG_BUFFERSIZE=131072 xsane But if the scanner works fine, there should not be any need to do this. This option is useful only in the case that a scanner stops the scan head very often during a scan. Increasing the buffer size and thus increasing the amount of data transferred for one read command can help to reduce the number of such scan head stops. But I assume that a document scanner like the IS420 does not show such scan head stops. Abel

[sane-devel] Business card scanner - scanshell 800dx
All, I want to make this scanner work with SANE. I opened up the scanner and looks like this scanner uses Genesys Logic 842 chipset (very similar to 841). I'm able to make few modifications to the genesys backend and make this scanner recognized by scanimage program. The lights come on and even the xsane recognizes the scanner. However, I'm unable to make the motor work. Anybody has any idea on this? If the scanner works, I will make my modifications available to the community. thanks -krish -- next part -- An HTML attachment was scrubbed...
