Hello Winni,
You should read the linux README included with the SANE source, to
show you how to compile.
Then you can avoid making such a mistake as trying to write into your
system directories.

Re: [sane-devel] Canonscan N 650U LIDE Scanner does not scan but makes terrible noise AGAIN !
Hi,
thanks for the answer.
Last year Andrea Vai helped me out. Now, I checked to repeat the
procedure of recompiling as Andrea told me and before him Gerhard told
Andrea.
One question to the developers? Last year with the end of october,
Andrea Vai and I attributed out tiny effort with the Canonscan N 650 to
bring out the the new sane-backends-1.0.24 or sane-backends-1.0.25. If I
still do have sane-backends-1.0.23 with Ubuntu 14.04 LTS then I guess
something went wrong?
For me virtualbox solved my problem. WindowsXP32 guest and Linux host.
But to make virtualbox work is not just made by installing it...
Regards,
Winni

Hi, I wrote the message below two months ago. Even after recompiling the latest sane-backends 1.0.24 I have to do the tweak with the symlinks described below. Furthermore scanimage -L only find the scandevice when root, which is not the most sensible solution. Is there somebody who can help out or at least tell me where I might find a solution to this problem.

Hi, A couple of weeks ago, I was confirming this bug with the help of Andrea Vai. Gerhard J?ger wanted to implement the changed speed into the script until release. Now, with a new version of Linux Mint 15 I downloaded, configured and compiled/installed the sane-backends 1.0.24. The bug is still there! Unfortunately my mailserver automatically deleted the info for tweaking this bug manually. Is there anybody who can help me? Thanx, Winni

[sane-devel] Canonscan N 650U LIDE Scanner does not scan but makes terrible noise
Hi, with the help of Andrea Vai I was able to modify the file plustek-usbdevs.c @ line 2064 entering 0.76 for dMaxMotorSpeed. After that Andrea Vai showed me via Email recompiling sane-backends-git20130901 Only recompiling did not work, so we had to rename and modify the symbolic links in /usr/lib/x86_64-linux-gnu/sane from libsane-plustek.so - /usr/lib/sane/libsane-plustek.so.1.0.22 libsane-plustek.so.1 - /usr/lib/sane/libsane-plustek.so.1.0.22 to libsane-plustek.so - /usr/lib/sane/libsane-plustek.so.1.0.24 libsane-plustek.so.1 - /usr/lib/sane/libsane-plustek.so.1.0.24 output scanimage -L [sanei_debug] Setting debug level of plustek to 5.

Most of time when I get noise
from my LIDE30 is when the head moves back for some alignment to the

I'm a bit confused here (honestly I didn't follow the thread careful
enough - sorry). You're talking about a LiDE30 - right?
This one is different to the N650U wrt settings of the motor...
I
tried to power the scanner from my bench supply with success but only
very slight changes to my scan results. I did measure the voltage at
the scanner down a 1.8M cable I got off ebay which had 24awg conductors
and it hovered around 4.6V. I was concerned more about power since I
noticed when connected into a cable powered hub it actually makes the
noise nearly all the time and other times read errors are produced.
Interestingly the specifications for the scanner want a 1.5M cable or
less from canons website which means probably a very short cable since
they seem to come in standard lengths.
This point seems also to be important. I was not aware that Andrea has
connected its scanner to an USB hub.
[...]
Anyway, FYI Andrea is currently testing some tweaked motor settings
for the N650, maybew this is the way for you to go as well. The only
thing you need to do is to recompile the plustek backend with
changed settings. Check the file plustek-usbdevs.c, around line 2330
you should find the following:
/** Canon N1240U/LiDE30 */
static HWDef Hw0x04A9_0x220E =
{
0.72, /* dMaxMotorSpeed */
0.30, /* dMaxMoveSpeed */
IIRC MaxMotorSpeed is used during scanning, so if the scanner gets
stuck during a scan, try and lower that value. MaxMoveSpeed should
have influence on the speed while moving the scan head.
HTH,
Gerhard

Hi, thank you for the reply. With the essential help from Gerhard we

That makes sense, as Gerhard suggested me:
---
Are you able to compile the Plustek backend? If yes, you might play
with the following values in the file plustek-usbdevs.c @ line 2064 and
2065
There you see the following:
** Canon N650U/N656U */
static HWDef Hw0x04A9_0x2206 =
{
0.86, /* dMaxMotorSpeed */
0.243, /* dMaxMoveSpeed */
I would suggest to reduce the 0.86 to 0.80 or 0.76, compile and install
the
backend and try again - you should also test various resolutions.
Another suggested setting was to use 0.85 and 0.240...
I tried with 0.76/0.243 and it seems to work (20+ scans at various
resolutions without noise).
But now what? Which are the best settings? Do we have to assume that the
best settings are any that seem to be working, or use some criteria and
choose them among the ones mentioned above?
Winni, can you confirm that this works for you too?
FWIW, In windoze I can use SnoopyPro which logs USB messages to
scanner with timestamps. So it could be measured to some degree.
...for example, might I try to do such a measurement, or it's not worth
it?
Thank you very much,
Andrea

[sane-devel] Canonscan N 650U LIDE Scanner does not scan but makes terrible noise
Hi, Further testing shows it still makes noises and missing steps due to motor lockup on my LIDE30, even when externally powered (hack). I played with the resolution as this seems to change the motor step and certainly higher resolutions kind of recover but low ones, quick movements fail to start. I am using turn off all calibration so not sure if this is part of the issue. It does not do this with the twain drivers in Windoze on the same scanner.

Try different USB cables, assuming we are not talking about PP scanners? I found out getting a short cable, like 1foot (molex brand) with conductor writing on plastic as 22awg/C2 gives better performance with no noise yet but I've still to play. Just in case this is actually a power issue, not that I want to suggest there is nothing else wrong. The cables I got off ebay at long lengths didn't work at all.

Most of the time it starts with the horrible noise but sometimes it works. I'd say every 5th try works. Even calibrating under XSane results in that noise... I searched for a plustek config file but could not find it. By the way, there is a hint about awfull noise in the FAQ.gz at /usr/share/doc/libsane/plustek/ SYMPTOM: Scanner makes awful noise PROBLEM: This can have two major causes: - You have an ASIC96001/3 based scanner, then the sensor hits the scanbed: !!! TURN OFF SCANNER POWER !!! - You have an ASIC98001 based scanner, then the motor control does not work correctly -- hit the cancel button SOLUTION: - For the first case (ASIC 96001/3), there's no solution available. This happens, when the driver can't keep track of the stepper motor. The image you get is normally unusable. The second case is often reported when the printer driver lp.o is already loaded. So remove lp.o before loading pt_drv. Regards, Winni

[sane-devel] Canonscan N 650U LIDE Scanner does not scan but makes terrible noise
Hi, Just a comment from my playing with LIDE30. Try different USB cables, assuming we are not talking about PP scanners? I found out getting a short cable, like 1foot (molex brand) with conductor writing on plastic as 22awg/C2 gives better performance with no noise yet but I've still to play. Just in case this is actually a power issue, not that I want to suggest there is nothing else wrong. The cables I got off ebay at long lengths didn't work at all. Unfortunately the LIDE30 does not have an external power option, perhaps others in their ranges do.

[sane-devel] Canonscan N 650U LIDE Scanner does not scan but makes terrible noise
Hi, my Canonscan N 650U LIDE Scanner does not scan but makes terrible noise, as if the scan unit is going in the wrong direction. The scanner works fine with Win XP 32-bit OS: Linux? Kanotix Dragonfire (Debian based) 64-bit scanimage (sane-backends) 1.0.22; backend version 1.0.22 Software: Xsane, Xscanimage It does not make a difference using XSane or XScanimage. First I have to choose the source device which is plustek:libusb:006:003 Any help is appreciated. Regards, Winni -- next part -- An HTML attachment was scrubbed...

First I have to choose the source device which is plustek:libusb:006:003 Just a shot in the dark and an obvious question but if you have a lock slider button on the base, I guess you checked that the scan mechanism has been unlocked? I have a Canon (different model but still a flatbed) and once I forgot to unlock it and had similar symptoms to you until I unlocked it -- mike c -- next part -- An HTML attachment was scrubbed...
