Thanks Jim,
That's a good thing to know. Manually advancing the mechanism that way. Great way to trouble shoot by seeing all the action in slow motion.
I ran mine through that way and typed out the letters that are showing up low. When typed out by manually spinning the motor, they show up correctly in a nice straight line at the proper height.
Only when machine is powered do they go askew and low.

damn little springs !!!
look at it this way ... if the spring was not
important to proper function, chances are
Teletype would not have included it. :))
congrats on finding that obscure solution.

ps: too late now, but I was going to suggest
that since you are sure that the keyboard is
sending correct codes, turn the machine off
but leave it in the local loop. press a key on
the keyboard and then slowly rotate the motor
in the proper direction ... as you rotate, the
kbd should generate the proper mark and space
sequence for the letter you pressed; as you do
that, the local loop will be keyed, the selector
magnet will respond; the code selection bars will
respond to the selector magnet moving; and that
bit should set up properly on the code selection
bar of that bit. When all five code bits have been
generated by the kbd, the code selection bars
should be in the proper positions -- if they are,
then they are working ok; then you will have to
continue manually rotating the motor and watch
the typebox alignment and see if it is responding
correctly. This should all work in 'slow motion'
as you manually rotate the motor.
A code bar or other item missing a spring should
be spotted right away as it will not respond as
it should.
