[GreenKeys] Model 26 feed issues - carriage shifting

[Richard Knoppow]

    I can't see what is going on well enough from the video. I 
assume the paper is not feeding correctly. On a typewriter this 
could be caused by a couple of things, one is the paper slipping 
in the feed rollers but you seem to have addressed that. BTW, I 
would use rubber belt dressing rather than brake fluid.
    I don't know how the platen it turned in the Model 26 but, 
again, if its like a typewriter there is a ratchet gear on one 
end which has a stop pawl. If the gear is slipping on the shaft 
of the platen or if there is play in the pawl it will cause the 
roller to wander a bit. You should be able to feel this by trying 
to move the platen with your fingers. I wonder how the line feed 
is accomplished in the 26, presumably there is a solenoid which 
causes the roller to turn. Perhaps there is a problem with the 
linkage from solenoid (if there is one) to the roller.
    Just some thoughts based on having worked on typewriters, 
maybe not applicable to the Teletype machine.
