8-1. Image Quality
Problem
High D-Min
Top 1/2 to 1 inch of the film
appears lighter in density.
Top 4 inches of each film is
slightly lighter in density or
there is a light density band on
the top 3/4 inch of the film.
Long scratches in various
locations on the film.
Cause
Film aged or not stored
properly.
Stripper felt pad has come
loose from metal backing plate
or metal backing plate has
bowed in the middle. This
allows leading edge of film to
bump into felt pad, causing film
to hop. This condition causes
leading edge of film to cool at a
much faster rate than rest of
film, resulting in light density.
Film exiting the processor is not
uniformly cooled. (Film is not
staying in contact with lower felt
stripper pad.)
Dirt and debris are built up in
the film path.
Solution
Run transport test to process
film without imaging. If film is
bad, advise customer of
storage procedures and/or
FIFO usage of film.
1. If felt pad has started to
detach, replace the pad
assembly.
2. If metal backing plate is
bowed, raising the middle,
remove pad assembly and
gently re-form the assembly so
it lays flat when attached to the
stripper assembly.
Inspect the felt stripper pads to
ensure they are in good
condition. Replace as
necessary.
Inspect and clean (as
necessary) the following areas,
in order:
Two part guide assembly
that guides film from film
tray into separator
assembly.
Stainless steel "scoop" that
guides film from separator
assembly to imaging area.
Front edge of film tray that
film rides over as it leaves
tray.
Guide plates that make up
the densitometer.
Plates that guide film into
processor assembly and
hold processor entrance
switch.
