Claim Text:
1. An imaging apparatus, comprising: an imaging system comprising a print media path; an optical sensor, comprising: at least one light emitter, wherein the at least one light emitter is configured to output at least a first light intensity and a second light intensity that is higher than the first light intensity during an imaging or printing cycle; at least one light detector; and a controller electrically coupled to the at least one light emitter and to the at least one light detector, wherein: the controller is configured to activate the at least one light emitter to selectively output the first light intensity and the second light intensity; the controller is further configured to receive data from the at least one light detector, the data configured to enable the controller to compare an amount of light output from the at least one light emitter and received from the at least one light detector; the controller is further configured to perform a self-check on the imaging system to determine an amount of light output by the at least one light emitter by comparing an amount of light received from the at least one light emitter by the at least one light detector during the self-check to a threshold value; and the controller is further configured to increase at least one of a voltage and a current to the at least one light emitter during the imaging or printing cycle in response to the amount of light received by the at least one light detector being below the threshold value to increase the amount of light output by the at least one light emitter during the printing or imaging cycle.
