However, if I try to do three or more pages the scan stops in the middle of the scan and fails with the error below.

[sane-devel] genesys Canon Lide 210 aspect-ratio-problem at 600 dpi
On 25/04/2014 02:55, Andrew Kanaber wrote: I hit the same problem with a Canon LiDE 110. I tried measuring the distortion by scanning a sheet of graph paper in various modes. With sane 1.0.24 in 600dpi lineart and gray modes the scan is stretched vertically by about 30%. Color mode scans are actually also stretched at 600dpi, but much less noticeably by about 2%. The stretching is still visible though if you compare the scanned images side-by-side. With version 1.0.22 the lineart and gray scans are correct at 600dpi but the 2%-ish stretching is still present in 600dpi color mode. In case it helps I've put some of the scans up at http://www.chiark.greenend.org.uk/~akanaber/lide110/ Let me know if there's something else I can do that might help, Andrew M G Berberich wrote: Hello, Canon LiDE 210 with sane-backends 1.0.24 (libsane:amd64 1.0.24-1.1+b1 from debian testing) has problems with 600 dpi gray and lineart. In 600 dpi gray and lineart the scan is partial and aspect-ratio is not correct. Vertically only about ? of the area is scanned and then scaled to the area, horizontally all is fine. (So probably the driver sets the wrong scanline-skip (to small)). This worked in older versions, at least 1.0.22. 600 dpi Color-scanning works fine, so do preview, 300dpi and 1200 dpi in all modes. 2400 dpi and 4800 dpi do not work at all, but never did. MfG bmg Hello, the vertical resolution is given by the motor speed which is eventually an int. So rounding errors may give ~2% distortion: target=((exposure * dpi) / base_dpi)step_type; Maybe by decreasing or increasing slightly exposure time rounding errors could be mitigated, but changing exposure may raise other problems. If the windows driver can do it, I'll manage to find something. I'll check how the gray scan beahves. The change between 1.022 and 1.0.24 is to use the LINESEL function when we try to scan below the minimal scanning speed of the motor. This should affect scans below 600 dpi, but not 600 dpi which is the minimal scanning speed. 2400 and 4800 dpi scans works on my LiDE 210. So I'd need some logs or better information on what is not working for you. I'm currently working on shading calibration problems for gl646 based scanners (HP2400 and HP3670). I'll look into this issues when I have finished it. If you have time for it, you can open a bug in the bug tracker (https://alioth.debian.org/tracker/?group_id=30186) and assigned it to me.

[sane-devel] Is --resolution x? y? or x and y ?
I'm trying to scan from a Brother MFC7360N. The specs say the max optical
scan resolution is 600 x 2400.
scanimage -A
scanimage: rounded value of br-x from 215.9 to 215.88
scanimage: rounded value of br-y from 355.6 to 355.567
All options specific to device `brother4:net1;dev0':
Mode:
--mode Black White|Gray[Error Diffusion]|True Gray|24bit Color|24bit
Color[Fast] [24bit Color[Fast]]
Select the scan mode
--resolution 100|150|200|300|400|600|1200|2400|4800|9600dpi [200]
Sets the resolution of the scanned image.
--source FlatBed|Automatic Document Feeder(left aligned)|Automatic
Document Feeder(centrally aligned) [Automatic Document Feeder(left aligned)]
Selects the scan source (such as a document-feeder).
I've tried:
scanimage -vvv --format pnm -x 215.9 -y 279.4 --mode '24bit Color' -d
'brother4:net1;dev0' --x-resolution 100 --y-resolution 200 --source FlatBed
-p
scanimage: value for --x is: 215.9
scanimage: value for --y is: 279.4
scanimage: unrecognized option '--x-resolution'
So it seems that if the backend doesn't expose --{xy}-resolution it doesn't
exist.
If I set --resolution to to 100, do I get 100 x 100 ? 600 - 600 x 600 ?
But if 1200, do I get interpolated X 1200(optical 600) and optical Y 1200 ?

The frontend program can only do whatever options the backend exposes.
Since none of us wrote the brother backend, none of us can answer your
specific question.

[sane-devel] MX925: Scan via Display to SANE??
For MX920 Series scanners you need to install SANE Development Version 1.0.25 from git. Button support is working as described in sane-pixma manpage. Due to a problem with the webserver, http://www.sane-project.org/lists/sane-backends-cvs.html#S-PIXMA doesn't represent the recent git version. But the infos for MX920 are up to date. I'll commit a patch for ADF paper empty issue within a short time.
