Abstract
An example print apparatus is described as including a fuser roller, a pressure device that generates wear on a section of the fuser roller surface, and a wear detection engine that identifies a degree of wear on the surface of the fuser roller. An example fuser roller may include a tube, a heating element, and a plurality of layers having a detectable pattern. An example print apparatus may include a wear detection engine having an emitter, a detector, and a controller that identifies a wear pattern based on data provided by the detector in response to activation of the emitter and determines a degree of wear based on the identified wear pattern.
