[sane-devel] SANE for Epson scanner is not working
Mark Deiss writes: Hi developers, I have Ubuntu LTS 12.04.1 LTS / 32 bit and also a Epson Perfection V10 flatbed scanner. I can't get it working and hope that it is just a matter of configuration. I do all what is needed to avoid that I have to use a Windows machine just to have the scanner working. I will post you all information I have and hope you can figure you why it is not working. Download driver of http://www.avasys.jp/lx-bin2/linux_e/scan/DL2.do That page no longer exists. Please download Image Scan! for Linux packages via http://download.ebz.epson.net/dsc/search/01/search/?OSC=LX Have a look at the FAQ for which packages you need to install at http://download.ebz.epson.net/faq/linux/faq_ls_2.html 2 packages: install first: iscan-data_1.13.0-1_all.deb than: iscan_2.28.1-3.ltdl7_i386.deb These packages are old and miss the non-free plugin needed for the V10. You need the following Debian packages for your architecture iscan_2.29.1-5 iscan-data_1.19.0-1 iscan-plugin-gt-s600_2.1.2-1 /etc/sane.d/dll.conf has line epson2 active /etc/sane.d/epson2.conf The epson2 backend (in its default setup) is known to cause long delays in device recognition and occasionally prevent the epkowa backend from doing its job. Try disabling it. enabled line: usb 0x04b8 0x012d This should not be necessary. On command line Scanimage -L is hanging. No response at all. Time out after ca. 1 minute. After pulling the USB cable or time out the response is: device `epkowa:usb:001:004' is a Epson (unknown model) flatbed scanner under root the same. Add line epkowa to file dll.conf before the line epson2. In epkowa.conf line usb is enabled and usb 0x04b8 0x012d When you install iscan from binary packages it automatically enables itself. When you install the plugin package, it automatically adds itself to the list of supported devices. There is *no* needs to do anything but install the required packages. Things should work out of the box. Too bad. This is not working Cost me some swearing. Hope this helps, -- Olaf Meeuwissen, LPIC-2 FLOSS Engineer -- AVASYS CORPORATION FSF Associate Member #1962 Help support software freedom http://www.fsf.org/jf?referrer=1962

[sane-devel] [Regression][Patch] genesys: Canon Lidescan 60, head does not return
Hi,
after upgrading from Ubuntu 10.04 (lucid, libsane-1.0.20-13ubuntu2) to
ubuntu 12.04 (precise, libsane-1.0.22-7ubuntu1), the scan head of my
Scanner stopped returning to its starting position after each scan.
I traced the problem down in sane-backends to
commit eba438b9
don't wait head to be parked at end of scan to improve scan speed
- issue slow_back_home without wait flag at end of scan
- ensure head is parked at scan start and at close
- issue slow_back_home before doing digital processing
The problem appears to be caused by
diff --git a/backend/genesys.c b/backend/genesys.c

[sane-devel] gscan2pdf v1.1.0 released
gscan2pdf - A GUI to produce a multipage PDF or DjVu from a scan. http://gscan2pdf.sourceforge.net/ Only two clicks are required to scan several pages and then save all or a selection as a PDF or DjVu file, including metadata if required. gscan2pdf can control regular or sheet-fed (ADF) scanners with SANE via libsane-perl, scanimage or scanadf, and can scan multiple pages at once. It presents a thumbnail view of scanned pages, and permits simple operations such as cropping, rotating and deleting pages. OCR can be used to recognise text in the scans, and the output embedded in the PDF or DjVu. PDF conversion is done by PDF::API2. The resulting document may be saved as a PDF, DjVu, multipage TIFF file, or single page image file. Much refactorisation of code was carried out to allow more regression tests and reduce duplication. The libsane-perl frontend feels much snappier as a result. Changelog for 1.1.0: * Fix applying default settings to widgets in scanimage dialog Closes debian bug #682818 (Presets aren't working) * Fixed bug editing OCR output. * Add profiles to libsane-perl frontend * Fixed switching to last directory on open/save * Fixed extracting image resolution in non-English locales Closes bug 3572463 (After update suse 12.2 pdf blank page) * Much refactorisation of code to allow more regression tests and reduce duplication * Fixed bug importing multipage PDF Closes bug 3574898 (Always imports all pages of a PDF) * Update to German translation (thanks to Jari) * Update to Greek translation (thanks to Stavros Kakaliantis) * Update to Gujarati translation (thanks to Vishal Goswami) * Update to Occitan (post 1500) translation (thanks to C?dric VALMARY) * Update to Turkish translation (thanks to Utku BERBERO?LU)

Hello,
like you wrote in bugtracker #313909, a flag is needed to the
device description of the LiDE60. Thanks for testing it.
It would be great if you could test the latest git source version.
I have improved a few things regarding head parking.
Regards,
Stef
