[GreenKeys] Model 14 Help

[Jim Haynes]

If the adjustments haven't been messed with - if the machine was working
right at some point - then usually a good lube job takes care of it. 
Which may involved working the parts back and forth quite a bit to free
them up if they have been stuck.

You can analyze the errors to get a better idea of what is going wrong.
Compare the code bits for what was sent with those for what was printed.
So you may find that a particular bit is being gained or lost, and that
will direct you to that part of the mechanism.

I have found in ex-Western Union machines a green varnish-like substance
formed on the separator plates of the selector.  I guess W.U. at some
point used an inappropriate lubricant that reacted with the nickel
plating to produce the varnish.  These I had to completely unstack the
selector separator plates and clean them and reassemble.

If the machine has a keyboard you can turn the motor by hand and see if
it makes errors at low speed or only when at full speed.
