Abstract
A sheet inspection station including pneumatic means for guiding the sheet past one or more measurement sensors in non-contacting fashion, thus eliminating measurement error resulting from fiber/dust buildup associated with friction between the sheet and conventional guide rails. Air is directed from components, that extend from a sensor surface, onto the sheet surface.
