7 Maintaining Your Films
Use the following precautions when handling your own films.
7.1 ANSI Cartridge
1
Allow a length of 700mm or
more for the film leader (the
blank section of film at the
beginning of a reel of tape)
and the trailer (the blank
section of film at the end).
2
Keep the edge of the leader
cut straight, especially when
the edge is folded, to ensure
that the film is unwound
smoothly.
In this case, however, make
sure that the leader is
700mm or more long.
If the length of the leader is
less than 700mm, splice a
leader tape to the leader us-
ing black tape to ensure the
specified length.
3
The film should not be twist-
ed 90° or more in either di-
rection when the
approximately 300-mm-long
leader is advanced out of
the reel and held straight
downward.
