I experience the same speed problem, either with xsane or simple-scan, with the same scanner HP Scanjet 3670. I think it is related to sane-backends, not simple-scan
I did a few tests : In a Windows XP virtual machine (Virtualbox 4.0.4 with USB2 support), on my computer : - the initialization takes between 12 and 16 seconds - the scan at 300 dpi takes 55 seconds - the scan at 600 dpi takes around 4 minutes - the scan at 1200 dpi takes around 30 minutes On the same computer, on Lucid 64bits, with the latest version of sane-backends (sane-backends - 1.0.22-0ubuntu1~lucid2 , taken from the PPA : https://edge.launchpad.net/~robert-ancell/+archive/sane-backends/+packages ) : - the initialization takes between 16 and 20 seconds. That seems to depend on the dpi settings and/or the fact that a previous scan has been made or not - the scan at 300 dpi takes 55 seconds - the scan at 600 dpi takes around 8 minutes - the scan at 1200 dpi takes around 90 minutes (I stopped it before the end) That would lead to the following assumptions for the linux driver : - the initialization time seems very long to me, but it might be "normal" on that scanner - the scan time is normal at 300 dpi, but should be improvable at 600 dpi (4 minutes vs 8 minutes) and 1200 dpi (30 minutes vs 90 minutes) ** Summary changed: - simple-scan is very slow when scanning at 600-1200 dpi + HP Scanjet 3670 is very slow when scanning at 600-1200 dpi ** Package changed: simple-scan (Ubuntu) => sane-backends (Ubuntu) ** Changed in: sane-backends (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/703322 Title: HP Scanjet 3670 is very slow when scanning at 600-1200 dpi -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
