The invention provides a wiping assembly in an image forming device, to clean at least one sensor lens in the image forming device. The wiping assembly includes a bracket to move between a first position and a second position across the sensor lens. Further, the wiping assembly includes a wiper to clean the sensor lens. The wiper is located between the bracket and a sensor housing, which supports the sensor lens. The wiping assembly includes a spring to actuate the movement of the bracket between the first position and the second position. The movement of the bracket is actuated by the movement of a print media tray and/or the movement of a toner cartridge.
