[sane-devel] Canon Pixma MP280: Error during device I/O

[Lars Noschinski]

Hi everyone,

I am trying to get an Canon Pixma MP280 to scan an image. I am using  
the sane-backends-1.0.23,
(packaged for Ubuntu from  
https://launchpad.net/~nathan-renniewaldock/+archive/sane) on Ubuntu  
12.04.
The scanner is detected without a problem, but if I try to scan an  
image, scanimage returns "Error during device I/O". Before this error  
occurs, I can hear that the scanner is moving its head shortly.  
Despite the error being "ETIMEDOUT", scanimage does not run for a long  
time; and most of that time is spent in device discovery.

$ scanimage --version
scanimage (sane-backends) 1.0.23; backend version 1.0.23

$ scanimage -L
device `pixma:04A91746_501A39' is a CANON Canon PIXMA MP280  
multi-function peripheral

If I search for ETIMEDOUT in the bugtracker, I find a few bugs which  
might be related (312918, 313894, 313952);
but none of them came to a conclusion. Please let me know whether you  
need more information or whether I should attach this information to  
one of the existing bugs.

Best regards,
