Cleaning with Ethanol:
Refer to safety instructions on
.
Attention: Ensure that no liquids enter the interior
of the device!
Spray the entire surface to be cleaned with
ethanol (cover the opposite surface).
Moisten a lint-free cloth with a small amount of
ethanol and remove the liquid by wiping the cloth
in the same direction applying a little bit of
pressure. A thin film of alcohol (which will
evaporate) should be left on the surface.
Note: Cleaning is successful if the film of alcohol
does not form any drops and evaporates without
leaving any streaks. Repeat the procedure if
necessary!
Dust (To Be Removed Directly Before Scanning)
Remove dust from the glass plate using a
grounded antistatic brush and oil-free
compressed air.
Note: Do not blow the compressed air over the
glass plate in short blasts as this would cause
condensation. Use a steady stream of air over the
plate!
The tray can be driven through an antistatic
device beforehand to avoid static charge.
