    Abstract: A method comprises switching on a first radiation source of a plurality of radiation sources. The plurality of radiation sources are for delivering radiation towards a print area of a printing apparatus. Each of the plurality of radiation sources may be connected to control circuitry via one of a plurality of circuit terminals. The method may further comprise detecting, using a detector, a change resulting from radiation from the first radiation source. The method may further comprise determining, using a processor, based on the detected change, connection information indicative of the circuit terminal to which the first radiation source is connected.

    Abstract: Examples relate to a 3D printing system comprising a connection to a 3D printing chamber; an energy source to apply energy to a 3D build material and an energy source chamber separate from the 3D printing chamber. The energy source chamber contains the energy source. The 3D printing system comprises an air valve system, the air valve system comprising a first valve element selectively connecting the energy source chamber and the connection to the 3D printing chamber and a second valve element selectively connecting an external air input and the connection to the 3D printing chamber. The 3D printing system also comprises a first sensor measuring a temperature representative of a temperature in the 3D printing chamber and an air valve controller connected to the air valve system to regulate the temperature in the 3D printing chamber in function of data provided by the sensor.

    Abstract: In one example in accordance with the present disclosure a print media lighting system is described. The system includes a multi-colored array of lighting elements to illuminate a print media as the print media passes through an illumination zone of a printing device. The multi-colored array of lighting elements are alterable based on a target lighting profile. The system also includes a control device electrically coupled to the multi-colored array of lighting elements. The control device alters emission characteristics of the lighting elements to adjust an actual lighting profile towards the target lighting profile.
