- In this video, you will learn how to load the Scott Mod Slimroll Towel Dispenser System. Open the front cover using the push button or key. Remove the used core. The Scott Mod Towel Dispenser System combines a color-coded core plug and matching roll holders. Only the core plugs and matching roll holders will work together. Thread the sheet into the dispenser mechanism by placing the tail under the white stationary roll holder shaft, while rotating the emergency feed knob. Once the sheet is threaded around the drum, and can be seen near the dispenser opening, close the dispenser door firmly and begin dispensing. In this portion of the video, you will learn how to load the stub roll. When the main roll is approximately 2 1/3 inches in diameter or about the same size as the diameter of the main roll holders, you can move the roll of paper from the main hubs to the stub roll tray. Set the used roll of paper on the stub roll holder arms. Place a new roll of paper on to the main roll holder arms and feed the sides of the tail from the new roll, under the blue clip located on top of the stationary roll shaft. Push the towel tail down over the blue fin, which is located near the front of the module. This will keep the main roll from feeding until the stub roll is depleted. Close the dispenser door firmly and begin dispensing.
