Checking changing paper sheets for presence


The presence of paper sheets and transparent sheets is to be reliably detected, even if changes constantly occur between transparent and non-transparent sheets during printing. The check takes place in a dusty environment.


PRK 18 retro-reflective photoelectric sensors are used. Here, an additional teach function – which is performed on every format change – ensures reliable detection of the respective material.
