[GreenKeys] M28 printer FIGS-LTRS weirdness

[Nick England]

I just adjusted the oscillator rail left shift link age and voila! - now my
M and period match up and my errant # has disappeared.
Jerry Murphy diagnosed the symptoms and pointed me to the proper adjustment
for the cure. See below -

I confess that I am really slack when it comes to getting a "basement find"
unit running again. I have never gone completely through the entire
adjustment procedure. I just try to clean, dissolve the frozen grease,
re-lube, turn it on, and troubleshoot obvious problems. And I have never
had to make that typebox shift adjustment before.
Getting this printer going has been a good experience and I have learned
things that should come in handy in the future.....if I don't forget them
by the time the next basket case turns up on my bench.
Cheers,

Go to:  https://navy-radio.com/manuals/tty/573-115-700-iss7-6607.pdf   and
then look for adjustment 2.47 -  Printing Carriage Position.   2.47 will
make sure that the hammer is hitting squarely on the M typepallet.  When
you are satisfied that the print hammer is hitting the letter M correctly,
go to adjustment 2.48.  2.48 ensures that the print hammer is striking the
selected typepallet in the figures field squarely.  The adjustment calls
for checking with the letter O and the numeral 9 but feel free to use the
letter M and the period.  At this point, I feel pretty certain that you
will find that an adjustment is needed.   Check and see if adjustments 2.49
and 2.50 need any attention.
