Cleaning the Sensors
Bank notes are often soiled, particularly by dust. The
dirt deposits on the sensors during the counting
process. Soiled sensors are the most frequent cause
of malfunctions.
Clean the sensors with the brush supplied. Open the
bank note counter to clean the sensors. How to open
the bank note counter is described in the following
steps.
A frequent source of errors is soiling of the sen­
sors (see Cleaning the Sensors).
