button until approx. 2 cm of the printer paper is protruding
from the housing and then close the door.
10.7 Replacing the Cleaning Paper
A red marker on the cleaning paper indicates the end of the paper roll during operation.
The remaining paper is sufficient for two or three more charge measurements. After that, the roll must
be replaced.
Corrupt measurement results: A check for cleaning paper is not performed
automatically. The system also works without cleaning paper. In this case, the sensor is
not cleaned and the samples mix with sample residues from previous sample
measurements.
1. Cut the end of the paper roll at an angle.
