[scanner] sane: every second scan fails

Hi everybody,

I got a Canon MP510. I'm already in the group 'scanner' and using sane to scan images:

scanimage --format=tiff >image.tiff

scanimage -L shows:

device `pixma:05B43737_53450F' is a CANON Canon PIXMA MP510 multi-function peripheral

Every second time I get an error:

scanimage: sane_read: Error during device I/O

So i have to scan everything twice.

dmesg says:

usb 1-3: usbfs: interface 1 claimed by usblp while 'scanimage' sets config #1

'rmmod usblp' has no effect. /etc/sane.d/canon.conf seems to be ok.
so what is the problem?

Re: [scanner] sane: every second scan fails

Once I had a issue like yours, so I decided to go merciless against dll.conf. I deleted every single line which wasn't required by my scanner and problem solved.

p.s. check sane's man page about SANE_DEBUG env variable. It will help a lot debugging sane issues.

Luck


They say that if you play a Win cd backward you hear satanic messages. That's nothing! 'cause if you play it forwards, it installs windows.
