I have opened the following ticket for 4800 dpi scanning on Canon LiDE 220:

I just want to confirm, does this scanner support 4800 dpi x 4800 dpi
scanning as indicated in the manufacturer specification? I was
checking 4800 dpi scan in GIMP and I see blocks of 2 duplicated pixels
in the X direction when scanned using SANE but not when using Canon
ScanGear on Windows.
