If the "Hanks Effect" was really so prominent, then we should see the commensurate rise in price of 5 Series Smith Coronas and particularly the Clipper and the Silent which he's also mentioned several times. In fact, he's said these would be the typewriter he'd keep if he had to get rid of all others. Given this fact, it has to be, in part, a variety of other factors which inflates the prices.

Personally I think that it's a combination of the fact that they were manufactured at the peak of typewriter use and manufacturing and before companies began using more plastic and cheaper manufacturing methods, but were also done in a later timeperiod when exterior design and color were on the rise as a differentiator in the marketplace. Quality, form, and function become part of a trifecta which drive desire and collectability.

It can be useful to take some mineral spirits, naphtha, or paint thinner and a tooth brush (or, even better, a brass bristle brush) to your typeface every now and then to clean the ink, dirt, paper, bits of ribbon, dust, etc. out of it. Doing it after changing ribbon is always a good idea. If you're really hard pressed, nail polish remover (acetone) or rubbing alcohol and a cotton ball along with a small pin tip for the loops of letters like 'a', 'o', 'p', 'g', etc. can be used.

How well (or not) your typewriter works from a print perspective can also change with the type of paper you're using, what your ribbon is made out of (usually nylon, silk, or cotton), how much ink it's got in it and how old/worn it may be. A good backing sheet behind your typing paper can also be helpful.
