Patent ID: 7236710

Claim:
An arrangement for determining a position of a unit in an electrophotographic printer or copier, comprising: a sensor arrangement comprising two sensors and an actuating element, each sensor outputting 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 the 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; and 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.
