James,

Perhaps Geotech might have such as Al Hrubetz suggests...but being as ink
stylus writing went out
long ago...one may have to resort to other (surplus...read: junk or unknown
condition substitutes) brands.
The tips of worn pens usually gets worn out or abrasively flattened to where
the ink flow smears all over
the place; rather than flow evenly and write with little snagging
"sharpened" pen tip effect...as you likely already know.  I've never figured
out how to "round out" or "smooth the outside and inside" of the writing
tips to effectively, re-use such.

Sometimes....the pen tip isn't exactly flat to the writing drum surface (the
prior tube gets bent up, down
or sideways...and this condition will give the impression that the pen isn't
working...you might check
that first....in all directions of movement.

Heated (electrical resistance) tips might be a consideration, but the
thermal paper prices are out of this
world for obtaining and prices are the same of course.

If you want to eventually take it email private, I do have a "junk box"
assortment of other brand pens; that ~~~might~~~be mechanically adaptable if
all else fails.  It might involve cutting, solder or glue or other
monstrocities of the original pen.  If you have a accurate micrometer or
vernier gauge that tells the outside and (rough) inside diameter of the
pen; that "might" help.  Chances are probably poor for a match; and it may
involve you "adapting" a different brand or size.  There is zero guarantee
of my junk; they may be worn out also, or dried ink clogged; I've not used
such for many years...it can be extremely frustrating to fuss with and get a
"good" one.
