Cleaning the Optical Window when Dirty
Different methods will work better under different conditions depending on load and
medium. What is the best approach?
Note:
Clean sets 3RG7838-1AA are available for cleaning
the optical window. They contain a special cleaning
agent and suitable cleaning cloths. Two sizes are
available. For more information, see the chapter
entitled "Accessories and Spare Parts".
Please note:
Generally it is sufficient to remove particles relatively
quickly moving the cleaning cloth horizontally. If
cleaning takes longer (for example because of
fingerprints), the scanner will report the fault in optical
window monitoring (after cleaning, press "Restart").
