[GreenKeys] On a 14 is that Little cylinder of plastic all there is to the Platen? Jan KD6EM

I gave in, broke down and bought a coverless 14 typing reperforator on Ebay.  
I just had to see the chadless tape with the printing on it that all and the 
books keep talking about.  I just got it yesterday.  Too much excitement this 
close to Christmas!  Well, I cleaned the unit, replaced the few wires, oiled 
her up, and she flew into action.  Punching and tape feeding and noise making, 
but no printing with a new ribbon yet.  The keys were coming down in the right 
order and missing the wire ink ribbon holder.  The only way I can get the 
unit to print is if I put excessive slack in the ink ribbon.  The ribbon wheels 
turn super free, but it seems that when the slack is taken up on the ribbon, 
the visible printing goes away.  Does the little plastic cylinder that acts as 
the platen have anything to do with this?  Can the platen be adjusted up or 
down? Is there a rubber part that fits on top of this plastic 1/4 inch diameter 
cylinder? Underneath the plastic cylinder there appears to be an aluminum disk 
with a tiny hole in the center.  Would there be a rubber cushion under this 
aluminum disk.  Would there be a spring under this disk?  

Hope someone can solve the mystery. 
Thanks,
