Abstract: Certain examples described herein relate to calibrating a cleaning element for a printhead. A print medium sensor is aligned with a nozzle plane of the printhead to detect displacement, during a print job, of a print medium out of the nozzle plane. Relative movement between the cleaning element and the printhead is enacted. During this movement, activation of the print medium sensor is detected. A reference position for the cleaning element is stored based on the detected activation.
