Cleaning the cassette sensor/peel sensor
•
The cassette sensor and peel sensor are easily influenced by the environment. Sensitivity may
deteriorate due to corrosion caused by dust and moisture outdoors.
•
Labels are issued by engaging the white gear and the cassette gear. If dust or labels are left inside
the mechanism or behind the cassette, the cassette cannot be fully inserted, and a label feeding
failure may occur.
