Arrangement and method for determining the position of a unit in an electrophotographic printer or copier

摘要

In an arrangement and method for determining a position of a unit in an electrophotographic printer or copier, a sensor arrangement is provided which comprises two sensors and an actuating element. Each sensor outputs a sensor signal dependent on a position of the actuating element, the position of the actuating element with respect to the sensors changing dependent on a position of the unit. In a first position of the unit, the actuating element is positioned such that the first sensor and the second sensor each output a first sensor signal. In a second position of the unit the actuating element is positioned such that the first sensor outputs a second sensor signal and the second sensor outputs the first sensor signal. In a third position of the unit the actuating element is positioned such that the first sensor and the second sensor each output the second sensor signal. In a fourth position of the unit the actuating element is positioned such that the first sensor outputs the first sensor signal and the second sensor outputs the second sensor signal.
