Any way to fix a slightly bad scan?

[Russkitav]

I have a comic that has bad scanning with pictures like where you can see that a little bit of the righthand side is blurry. On some of the pages in this comic, there are pieces of text that lie within the blurry zone (they can still be read, but they're blurry). It is not possible for the source to be scanned again, so I am wondering if there is some sort of editing solution. I would greatly appreciate any assistance in resolving this issue. Thanks.

If you use Photoshop, one way is to use the selection tools like the magic wand set at a low tolerance to select the grayed out areas (careful not to include the line drawings and use brightness and contrast. to increase the white.

Use the eraser on the dark splotches on the page edges.
