An electrophotographic printing machine frequently employs sensors. Sensors are mounted on brackets within the printing machine. Most sensors are secured using two or more fasteners to hold them in position. This requires the operator to use two hands. One hand is used to hold the sensor in place and one to tighten the fastener. The use of two fasteners requires additional time. Alternatively, the sensor detector and emitter may be mounted on a common bracket with the rear detector being fixed. The front emitter has the ability to float up or down within the slot and is held in position by a spring loaded arm. When the required position is achieved, the emitter is locked into place by the use of one nut. This spring loaded arm acts as a secondary tie down. This allows a person to adjust a sensor and lock it into position using only one hand. The adjuster is located on a shaft held to the mounting plate with a curved spring washer and E-ring. The curved spring washer provides the force that keeps the adjuster in a fixed position. By pushing in and rotating the adjuster up or down, the sensor can be aligned. For releasing the adjuster holds the sensor in position while the locking fasteners is tighten. The sensor may be adjusted in either the vertical or horizontal direction.
