Any ideas or advice you may have would be
GREATLY appreciated.
The rightmargin works like what you are describing here.
Make sure the two pointers on the front of the machine
(the carriage indicator arrow will move between them)
are set to the left hand and right hand of the machine,
and not together.
If I recall, the carriage ball will no longer type when at the
rightmargin, so this is just a suggestion to try.
