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

[hwhall@aol.com]

The part pointed to by the screwdriver is the LF Push Bar. The spadelike part above it, near the step on the bar, is the Function Bail. Like you, I believe the Push Bar is out of position (too high) & the bail is catching it on every print cycle.

Okay, it’s been a while since I’ve fiddled with my 19, so decided to take it apart.  I did a real world test of taking off the one spring that’s not diagramed and it just caused LF to not feed… so I can’t see how the other spring would do anything much different (I now think my issue was that it would not LF because the spring was off… oh well).  However, looking at the bottom-left of the printing unit… you said you reassembled it after cleaning (or something), right?  I wonder if that either:

1 — photo attached — the part that I’m pointing to with the screwdriver (and to the right… the part being the LF lever) are slightly misaligned to where they're constantly getting caught on the upper tooth of the lever and is getting pushed to do a LF whenever the shaft rotates.

2 — the veins are slightly bent (or misaligned) to where it constantly throws a LF signal onto the teeth (slightly more unlikely but possible).

Please forgive my terminology if it’s off but it’s been years since I’ve poured over this stuff ;p .

One I point out with a pen and the other — again, not immediately obvious in the diagram that I looked at, is in the left-center frame-portion of the vertical video.  For some reason I remember that the one that went missing on mine was next to the platen, but I could be wrong.  A screenshot of that portion next to the patten is also attached.
