Thanks for the quick response!  I haven't actually gotten to take a look at the magic margin, because I couldn't figure out how to open up the paper table-thingy.  I will try playing with it and see if I can get some penetrating oil in there and see if it loosens things up.  It has to be meant move over at least a little--there would be no point in the extended-sized carriage if I couldn't get the margin further to the right than it was currently.  

@tricnomistal: If I understand what you're describing, your right margin doesn't move at all, and it's currently set around the mid point of a letter-sized sheet of paper? I'm also assuming that when you type you have to use the margin release key halfway through every line?

Indeed, that is pretty much the scenario.

Thanks again to everyone for the responses.

I have a quick update: After removing the cover over the margin controls (the paper table?) And manually moving the right margin, it was obvious that the margin control itself was not to blame.  Instead, there seems to be a problem with the functionality of the right KMC key.  Though I am not enough of an expert to describe properly what is happening, it seems as if the key is doing what it is intended to do--raise and lower the bar with the margin controls on it--but the key doesn't seem to raise the bar high enought to unlock the right-side margin control device.

I hope that makes sense; I wish I could describe it all more accurately.

Anyways, if nothing else, I can now use my typewriter without hitting the Margin Release key with each line.  I fear pulling it apart any further to try and fix the key only to have something else go wrong.  Also, this little fix allowed me to find some other minor flaws, like the fact that the ribbon reverse doesn't seem to work and the bell only likes to ring when I manually slide the carriage.  Nothing I can't live with for the present.

Thanks again for the help!

Any other tips and suggestions are still quite welcome.

If the bar is not raising high enough, it could either be lots of dirt somewhere, or an adjustment. The bell sounds like it needs some degreaser. That happened with mine too.

By the amount of dust on the inside of the inside I would say that there is a build up somewhere that is preventing the key movement.  Though with how complicated it is on the inside (compared to my portables), I doubt I will want to do too much dissasembly for cleaning--as much as I would like to.  I have a bottle of oil that I might try and use on the bell mechanism.  Hopefully that helps.  Thanks!
