[GreenKeys] Weak print on 14 reperf

[epvgk at limpoc.com]

All this talk of print adjustments reminded me... my Model 14 reperf prints pretty
light. It's one that has a lever to lift the ribbon, and I can see that the position
and shape of the wire ribbon guide is important (on mine it's kind of beat up), but 
I wonder if anything else is adjustable. 

I can get by using really densely saturated ribbons but i'd rather it print darker.
The little platen nub is pretty new looking (a gift from a greenkeyer) but also fits
quite loosely in its hole, and i dunno if that's how it's supposed to be either. 

thanks!
