missing reagent to the correct
reagent vial. You have one
minute to add reagent after
which some slides may be
skipped. Check Run Log for
“Insufficient Reagent **Skipped
Slides**” message.

in the correct locations in the

environmental conditions are
contributing to the drying of the
slides (i.e. direct sunlight,
heating/air conditioning vents,
hoods, etc.)
