[GreenKeys] M-15... Auto Line Feed After every printed character

[john WA4KWK]

Wayne thank you so much for your efforts. The spring is there.... looks
intact. Rotating the motor by hand.. the platen does a LF each cycle. Hard
to see but the LF Push Bar moves cleanly each cycle.
Not sure what to do next. But I will continue.

Thanks again,
John
