35mm curl in Epson 4870 holders

I'm new to this scanner, and wondering if there is no way to do
something to get 35mm negs to lie flat in the Epson holder? Will
putting a piece of clear glass on top of the negs help?
Thanks.

No. If you put glass on your negative you'll start to see newton rings. If
you can get your hands on anti-newton glass it might work. What's really
needed is a better carrier from Epson. Maybe another brand of scanner has a
better carrier which you can order as a part.
 
Have you tried flipping the negatives over to see if they scan better? I
know that sounds simple, but sometimes it really helps. You can easily
"flip" them bac to the correct orientation from within Photoshop.

Just to mention, Anti-Newton glas is bad idea,
it will certainly help you get rid of those Newton rings, but it will
also leave grainy structure on the image, due to it's surface.
And I'm speaking this from my classical Photographic knowledge, although
many photographers use that kind of a glass, many of them don't know
this, or they are blind ;).
If you must use something, there is a special kind of plastic foil that
is used with oil... but it is not suitable for batch scanning...

As for the films, what they need is proper storage...
then everything is a O.K.

I forgot to mention, Epson Perfection 4870 is not suitable for oil&foil
usage, it must be sealed before using this technique...
but don't bother with these if you don't scan large format
transparencies...

As you asked me in e-mail about proper storage of negatives...
To avoid curling of negatives, You should cut them in six frame strips
and insert them in special filling sheets that you can purchase in
nearby photo store. I use Kaiser sheets, as I can easily get them here
in Zagreb, the best ones for archiving are those made of special paper
(lookalike greasy), next on the list are those made of acetate (or
acetate and paper on one side), they are more transparent, but they tend
to stick on negatives and cause a static electricity, the last ones are
made of some kind of plastic, maybe polyethylene or polyacetate, they
tend to scratch emulsion and acetate base of films and static el. is
also big problem with them, bigger than with acetate sheets...

Anyway, immediately after developing and drying You should put them in
filing sheets, do not roll them back in the film canister box or so...

Some emulsions and bases tend to curl more than other, for example roll
format Fotokemika R25, well, put them in sheets and then between pages
of some big heavy book. After a week or two or maybe less you'll have
somehow flater negs...
If you develop yourself, there are also anti curling additives, but I
never used them, so I don't know if they are worth buying...

One more thing, if you have uncut curled b/w negative, you can resoak it
in plain water, add a drop or even smaller amount of liquid detergent
for dish washing, or Kodak Photoflo, or any similar product.
Then dry it in dust free environment hanged with some weight added at
the bottom...

In case of colour negative or slide film, you should ask in nearby photo
lab if they can help you with it, putting it through last bath in hanger
type machines and drying will help...
