[GreenKeys] Model 28 - Top edges of letters barely visible

[Jack Hart]

Jim,

There's a small set-screw below the typebox that adjusts the "tilt" of the
typebox against the platen. Give it a tweak. Usually, this adjustment
is never touched...but, platen wear could call for the tweak.
Also, make sure the typebox is OK...clean and lubricated.
Not to be mentioned, but worth it...check the ribbon, too!

73,
Jack K0TTY
NNNN

I have a 28 KSR I am refurbishing, and its printing on a loop, but the top
half of all characters is faded or not visible.  New ribbon. Cleaned the
type box.  I've increased the hammer spring tension adjustment, it gave me a
bit more of the tops but mostly just made the bottoms darker.  I slow
motioned the machine by turning the motor by hand and the hammer strikes
perfectly horizontally but it appears to be striking toward the tops of the
plungers.  Is there some kind of vertical alignment adjustment?

I have read about platens hardening with age.  Hopefully thats not the
problem.

Thanks,
Jim
