18 Troubleshooting
No exposure: A completely
black picture indicates that no
light reached the negative.
Check that your equipment is
functioning (shutter, flash
sync, etc.) This also can be
caused by failure to insert the
film envelope all the way into
the the holder when loading
the film; failure to withdraw
the envelope before exposing
the film; or failure of the
holder to catch the metal cap
when the envelope was
inserted. Check the film
loading instructions. If this
trouble occurs frequently,
check the film holder for
possible malfunction.
Black edge: Failure to
withdraw the protective
envelope fully before making
an exposure will produce a
black strip along the edge of
the picture. Always withdraw
the envelope as far as
possible before exposing the
film.
Missing corners: With black
and white film, this can be
caused by pulling too fast;
with colour film it can be
caused by pulling either too
fast or too slowly. Pull
straight, at medium speed,
without hesitation.
English
Spots: Deposits of dirt or
foreign matter on the steel
rollers will cause evenly
spaced spots or marks
across the length of the
picture. Inspect and clean
the rollers regularly.
Streaks: If your pulling
motion is uneven or jerky
when removing the film
envelope, the rollers will
leave impressions across the
picture in the form of vertical
streaks. Always pull
smoothly without hesitation.
Detached envelope: If the
film is loaded backwards, the
envelope will detach
completely when withdrawn
for exposure. To gain access
to the negative (which
remains inside the holder),
open the hinged cover and
disengage the rollers just as
you would for cleaning.
Move the control arm to P (9)
and withdraw the negative by
pulling the negative tab.
