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.
Claims15
A method comprising:
- switching on a first radiation source of a plurality of radiation sources, the plurality of radiation sources for delivering radiation towards a print area of a printing apparatus, wherein each of the plurality of radiation sources is connected to control circuitry via one of a plurality of circuit terminals;
- detecting, using a detector, a change resulting from radiation from the first radiation source;
- determining, using a processor, based on the detected change, connection information indicative of the circuit terminal to which the first radiation source is connected.
Apparatus comprising:
- a plurality of heat sources to direct heat towards a print area of a printing apparatus, wherein each of the plurality of heat sources is connected to control circuitry via one of a plurality of circuit terminals;
- a sensor to measure a change in temperature resulting from heat from a particular heat source of the plurality of heat sources;
- and
- processing apparatus to calculate, based on the measured change in temperature, connection information identifying the particular circuit terminal to which the particular heat source is connected.
A machine-readable medium comprising instructions which, when executed by a processor, cause the processor to:
- activate, successively, each heat lamp in a plurality of heat lamps, the plurality of heat lamps for directing heat towards a print area of a printing apparatus, wherein each of the plurality of heat lamps is connected to control circuitry via one of a plurality of connectors;
- identify, using detection apparatus, a thermal change caused by heat from each heat lamp;
- and
- ascertain, based on the identified thermal change for each heat lamp, mapping information identifying the particular connector to which each heat lamp is connected.
