Thanks, but this leaves patches of Gray.

Fast and easy for pure black and white: Colors > Threshold... on your original scan (remove the white after)
Adjust with the sliders, if it's too harsh > then after Filters > Blur > Gaussian blur... just a bit to smooth it out
Or
Colors > Levels...
Click on number 1 then pick the black on your scanned doc, adjust with sliders (number 2) if needed
My favorite is a S curve with Colors > Curves... as it allows multiple controls
Red arrow is a darker part (blacks), yellow arrows is lighter part (whites)

Double the layer and put the top layer into multiply mode
or
assuming the background is white? duplicate the layer and colour to alpha it (making the white transparent then dulicate that layer a few more times.

Using threshold should make your grey darker this is actually your best option.
or
using curves you bring the curve down in the centre
or using levels at value bring the centre arrow to the right
Thanks. My original is not clean enough. Guess, Gimp is not magic
