It is intended to leave no residue but if there are dyes
in the paper that it dissolves, it may leave rings. You need
to experiment a little. It will also dissolve some plastics
as well so always check first.
It is used to remove oils and old brake fluid from brake parts
in cars. I often use it to degrease parts that need to be extra
clean, such as when cleaning surfaces to epoxy.

I'm not sure if this will work for grease
pencils but
you might give this a try. Get a can of brake-clean from
the auto parts store. Place the page on a paper towel such
that the marked side is against the towel. Spray some
brake-clean, starting in a circular motion from outside of the
mark to the center. Remove from the towel before it dries.
Repeat with clean towel as needed.
I'd advise checking on some material that is similar first.
As I recall, I used this method on something like a sharpie
mark once. Use out side. Brake-clean will give you a real
bad hangover. It is mostly solvents and dry cleaning fluid.
I assume this evaporates to some considerable degree and does not leave
any marks or residue on the paper?

I haven't had any problem with it attacking plastics used on the disk
drives but I'd still recommend testing it first.

I use propan-2-ol for this. I recently did the drive in my Integral -- it
was so gummed up that one part appeared to be a stepped shaft. After
cleaning, it was shown to be a plain shaft with a couple of spacers on it!.
I would be very careful about spaying anything into a floppy drive. Not
only might it just move the gunge elsewhere (like onto the head!), but
also you don't want to disolve plastic parts, or even worse the enamel
insulation on the motor windings and head -- at least one enamel is
attacked by methanol! I prefer to take things a little more slowly, take
the disk holder apart, and clean all the parts seprately. It takes well
under 1 hour to do this, and I end up with a perfectly working drive.
