But simply consider this Pixma scanner: can we call it a scanner? Or rather an electronic microscope?
Cannot see a detail on a photograph? just scan it with your Pixma at 4800 dpi …
and you get about 50 x zoom magnification!


Just take a look at the rightmost image. Open, it. Guess a new carpet design? Nope, simply a detail of a classic French "Marianne" stamp (here, a full view at 600 dpi), as seen by the Pixma MP610, at 4800 dpi...
Now, some simple orders of magnitude...
- 4800 dpi means a resolution of 2.54 cm/4800 = 5.3 µm
- this is ~1/1.000 of a millimeter, or 1/1.000.000 of a meter
- and also simply… ~10000 times the atom size (1 Angström = 1E-10 meters) …
So ... Will future scanners be able to display … the paper sheet atoms?!
Installation
Nothing new, the same procedure as for previous version of this driver applies:
- simply install the latest sane-backends library (either 1.0.20 or latest git development and follow the installation instructions given in this post.
- Then, select in your frontend (Xsane, Kooka, …) a scan resolution of 75, 150, 300, 600, 1200, 2400, or 4800 dpi ... and start scanning...
WARNING:
Be very careful when scanning at such high dpi values, because you’ll get TREMENDLY HUGE ENORMOUS amount of data and file sizes!
You could fill up your entire disk space in one scan!
Watch carefully the frontend indications about file sizes, before clicking the scan button!
Note also that in case of very large images (like more than 20000 pixels width or height in Xsane...), a frontend crash might occur, due to the large image size...
