[GreenKeys] Model 15 Print Quality

[Richard Knoppow]

    If you have not already try picking out the hollow places on 
the B (or other letter). The safest tool is a wooden toothpick 
but a pin will do and with care will not scratch the surface. 
Very often the hollows get clogged with material from the ribbon 
or just compressed dust. Normal cleaning with a stiff brush may 
not get all of it so its worth trying. You can also inspect the 
surface of the type with a strong magnifying glass to see if any 
is worn or chipped. If there is about the only cure is replacing 
the type face but if its readable you can just live with it. I 
think the Model 15 dates from the mid- 1930s so the machine may 
be very old.
