A conditioner includes a pressure roller assembly, a heating element, a drive motor, a current sensor, a plurality of print media sensors, and a controller. The heating element heats the pressure roller assembly. The drive motor rotates the pressure roller assembly. The current sensor senses a current of the heating element. The plurality of print media sensors sense the movement of print media through the conditioner. The controller is to turn off the heating element in response to any one of detecting an anomaly in the sensed movement of the print media or detecting a sensed current outside a predetermined range.
