This sensor based blank sheet detection system includes a sensor on the top side of the machine and another sensor on the bottom side. These sensors automatically teach themselves & do not need time consuming set up. When sheets are passed, the system automatically inspects the sheets on both top side and bottom side. If the sheet is blank on either 1 side or both sides, the system immediately stops the machine and counts that sheet as a bad sheet. Good count, bad count and total count are displayed on screen. This system is robust and very cost effective.
