The Xerox DocuMate 3125 is an A4 desktop document scanner. Durability tests support a daily duty cycle of 3,000 pages. The scanner uses a CIS (contact image sensor) and an LED light source for efficient power consumption. The unit offers a 50-sheet document feeder for document. The DocuMate 3125 has ultrasonic double feed detection so that stapled or other misfed documents can be sensed before they are crumpled, destroyed or cause a jam.
