It might be a semidefect scanner when it gets stuck i can only get it to move back if i shake it a bit, else it just keeps being stuck somewhere when i press scan before the head is in position. if i wait patiently and never press scan before the head has come back to the start it seems to work now. so I guess the problem has solved itself, thanks for any help offered.

[sane-devel] vertical lines how can i help
i posted earlier that i got vertical lines when scanning and not in windows with canons driver on a canoscan n650u lide scanner. how can i help debug this problem/ is there any windows software i can use to get to what the windows driver is doing which sane apperently isnt it seems to be compensating for bad optics in the scanner, it doesnt like reflective images, it scans everything else ok. thanks Michael Ole Olsen
[sane-devel] vertical lines along image when scanning and not in windows
i am using a canon canoscan lide 650u i get vertical lines when scanning using xsane from debian etch, i also tried never xsane (testing) without better results the problem doesn't happen in windows with canons driver http://shell2.eushells.com/~dh/naff.png it is much more visible at higher dpi and resolutions, seems that you can see the scanning cable and head-sliding pipe reflected in the image somehow. i tried calibrating and all settings available in xsane, the problem doesn't happen with my scanjet 6300c which is also usb. any ideas what can be the cause? if you need usb driver output from windows i can perhaps supply you with it(i got vmware running) thanks, Michael Ole Olsen
[sane-devel] A few small problems with xsane
I got 3 issues while using xsane with my HP Scanjet 6300C: - Scanner button not working - No lamp turn-off - Scanner head moves forth/back while scanning and seems to be calibrating each time before scan (delay before scan=5-8seconds) I'm currently testing it on debian/testing. I cannot get xsane to switch off the scanner lamp automatically, it only works when you manually press the turn off lamp button in advanced settings for the scanner. if i just close xsane it never gets turned off, and im worried that it will eventually overheat the scanner's CCD sensor or just reduce the lamp lifetime, which isn't that long. the only thing which seems to work is rmmod'ing the usb module or unplugging it. also the scan buttons on the scanner doesn't work what could be the issue?, I am using libusb and no scanner modules loaded/in kernel. I tried various backends and xsane versions (mostly etch and testing) with no results. also I am having problems with the scanner stopping while scanning, even on lowest speeds for 175dpi and above. is it not possible to set scan speed slower than Slow in advanced settings dialog? i.e. set it manually using an integer value parameter to sane-backend. if I reduce the dpi, it scans without stopping, but I need to scan at 320dpi. Thanks, Michael Ole Olsen gnu at gmx.net
[sane-devel] HP ScanJet 6300C head moving back/forth during scan 200dpi
Hello, I am having problem using my HP ScanJet 6300C with libusb and xsane+sane backend from debian testing. I have also tried debian etch version on another computer with same issues, and I even tried downgrading my sane backend (then it went completely insane and almost broke the scanner). Right now im testing on a cometely fresh install of Debian/testing. There are no scanner modules loaded/in kernel and the kernel is PREEMPT 2.6.23.9 When I do a scan, it waits about 6-8 seconds before scanning (just like it is calibrating), then it moves the scanner head back and forth while scanning (only when i get over approx. 200dpi) I did read somewhere on this mailinglist, that it had to do with USB bandwidth, so the scanner must wait at above 200dpi for the transfer of data to complete over USB. I'm using it with a high-speed USB 2.0 hub, so i dont see how there could be any kind of transfer-bottleneck. I tried adding 'option enable-image-buffering' to top of /etc/sane.d/hp.conf just like man sane-hp says to make it global, with no results. I tried enabling debugging a few times, the output didn't seem useable, but I can post it if needed. I have had the same issues with a plustek scanner (Canon LIDE 30) and libusb: grinding noise and scanner head moving forth and back while scan 200dpi. Can anybody help me sort this out? best regards Michael Ole Olsen gnu at gmx.net
[sane-devel] HP ScanJet 6300C head moving back/forth during scan 200dpi
Hello again It's a USB-2.0 machine (the hub is integrated on the motherboard, ASUS A7N8X deluxe), and I have had no other issues with the usb hub running fullspeed; I get fine transfer speed to my camera with gphoto2 and to my usb-sticks. No problems under Windows and also no problems when using the scanner with scsi or scanner-server (rj45), so the scanner isn't wrecked. I cannot use the SCSI feature on this computer though - and I don't have the scanner server here, that's why I want to use it with USB. /michael ole olsen On Mon, 14 Apr 2008, m. allan noah wrote: On Mon, Apr 14, 2008 at 10:34 AM, Michael Ole Olsen gnu at gmx.net wrote: Hello, I am having problem using my HP ScanJet 6300C with libusb and xsane+sane backend from debian testing.

[sane-devel] HP ScanJet 6300C head moving back/forth during scan 200dpi
I think you may be right that the scanner is USB-1.1 , I have unfortunately only tested with scsi under windows and I dont have access to a Windows machine currently. What I could find out on google it seems to be usb-1.1 but im not 100% sure. I tried setting the scanning speed to low in xsane but the speed is the same as with normal speed still when scanning, i would think that this could fix the going back and forth of the scanning head because of the scanners potential usb-1.1 bottleneck ? /michael ole olsen gnu at gmx.net On Mon, 14 Apr 2008, m. allan noah wrote: no, i meant the scanner is usb 1.1. have you tried using the usb under windows? allan 2008/4/14 Michael Ole Olsen gnu at gmx.net: Hello again It's a USB-2.0 machine (the hub is integrated on the motherboard, ASUS A7N8X deluxe), and I have had no other issues with the usb hub running fullspeed; I get fine transfer speed to my camera with gphoto2 and to my usb-sticks.

I'm using it with a high-speed USB 2.0 hub, so i dont see how there could be any kind of transfer-bottleneck. it's a usb 1.0 machine? does it do this on windows? allan -- The truth is an offense, but not a sin -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.6 (GNU/Linux) iQIVAwUBSANxQiXlragqp/ZIAQKhuRAAkquaQNG5zNNJ1YSrXhAdCLLkAC9ymuIE Gg+cH1ca3EVZVMImM3u2SzM1ETJGCMf5KpGhFdeJd663UhWyNTlgLbkSjFzin3Ys q+W2zTkKqzSldQtWwzi8SRx00aJDlWq07btWLCK0DSfOtv6xAOh9hI6Mzgr3lGM2 jtlzJIVz8eWdVIRPHl3sf1esPVnuDBEdAYn6Cn/0oJBNFRX/V+N5AVnFkCXDoSEn qNYzWCCjWoNPFqC4ZzuD2EVck678twaxcji36kAmGDXscTWw65rOMxsKPMP4p5px EtVKsn+0x6NgsariuAtZvmlZqyoTkYU4BkMQWwLfCasszsWh+ka4/uBpguxj/8e0 KGKy3YkAw4H5MAr2H+sd+nFOLFaDanG75xb3wlXaDgtkSCk+Hkm/99+GI70XIEQK WC4Y7c5QtclbcgSxJM/Y+aNfur2l9Av2L+254EP7j66ZCDQh3dCKiYe2vQ1iM41i NHKeFBb7SIUsHihuEHQ6BmFwytMX3fZzaQ18HKcQlJDR6F8WOPbl2JGgi7d+guBd UXP2WgO+PUe5Ubgc+mlHaweF/RIsvGy+jmxUMuhnEftUaoXyByQkOFlJb1x5Z+p3 M2+jXFvY/bPzfXIMHU0sMHHsOShZck3KobX0z3gxLEMQ2U6A3lV2QqQFMaDDnFoN HvPzpPqPgBA= =p4Oi -END PGP SIGNATURE- -- sane-devel mailing list: sane-devel at lists.alioth.debian.org http://lists.alioth.debian.org/mailman/listinfo/sane-devel Unsubscribe: Send mail with subject unsubscribe your_password to sane-devel-request at lists.alioth.debian.org -- The truth is an offense, but not a sin
[sane-devel] HP ScanJet 6300C head moving back/forth during scan 200dpi
I found that I can scan at maximum of 160dpi at Slow scan speed. If there was a possible way to change scan speed to slower than slow, i.e. set some integer value for scanspeed, im sure it would make the scanner stop moving the head back and forth while scanning. if i set it to high scan speed it moves forth and back very often, and not so often at slow speed - tested with 200dpi is it possible to set scan speed with some argument to sane backend or such with hp libusb driver?

I have also tried debian etch version on another computer with same issues, and I even tried downgrading my sane backend (then it went completely insane and almost broke the scanner).

I tried adding 'option enable-image-buffering' to top of /etc/sane.d/hp.conf just like man sane-hp says to make it global, with no results. I tried enabling debugging a few times, the output didn't seem useable, but I can post it if needed. I have had the same issues with a plustek scanner (Canon LIDE 30) and libusb: grinding noise and scanner head moving forth and back while scan 200dpi. Can anybody help me sort this out? best regards Michael Ole Olsen gnu at gmx.net -- sane-devel mailing list: sane-devel at lists.alioth.debian.org http://lists.alioth.debian.org/mailman/listinfo/sane-devel Unsubscribe: Send mail with subject unsubscribe your_password to sane-devel-request at lists.alioth.debian.org
