Good at dispensing labels, needs improvement on general function

Labels dispense clean and consistent, but the machine randomly turns itself off. Seems to have some sort of built-in auto-off function that no one wants. Also, one of the two machines we bought had a sharp edge on the label feeding lip. Every time a label was dispensed, the machine would rip the backing. We used a file to smoothen out the edge. We also found that when using the machines under our bright warehouse lights, the sensor would often trip. We had to move the machines to an area not directly underneath our lights.
