I could scan.....but there is a problem with usblp:

$ scanimage -L
device `pixma:04A91743_3052EF' is a CANON Canon PIXMA MX870
multi-function peripheral

$ scanimage -T
scanimage: scanning image of size 638x877 pixels at 24 bits/pixel
scanimage: acquiring RGB frame, 8 bits/sample
scanimage: reading one scanline, 1914 bytes...  FAIL Error: Error
during device I/O

$ dmesg |tail -1
[ 5880.817977] usb 2-1.5: usbfs: interface 1 claimed by usblp while
'scanimage' sets config #1

I found many threads about this, but not sure what's wrong :(
