[GreenKeys] Figures characters printing lightly

[Steve Garrison]

Duncan the characters are in line OK (figures characters are just faint) so I'm not going to mess with platen for the moment. I'm now thinking it is the ribbon lift that isn't lifting quit high enough when the platen shifts to its upper position causing the character on the top of the pallet not to have the ribbon between it and the paper.  Therefore all I'm getting on the paper is some residual ink on the type face.

This is a TT-4A, so the adjustment is a small star wheel that shortens or lengthens the linkage when rotated.  I'll have to experiment with it after getting my demo set up later today as I have never adjusted this before.  Clockwise or counterclockwise that is the question!

I'll be demoing the TTY texting setup I have based on John Nagle's work at the ARRL booth at an IEEE conference in Atlanta this week.  I decided to use the TT-4 as we are limited on space and it is the smallest of my stash of TTYs.
