The Xerox DocuMate 3125 is an A4 desktop document scanner with speeds of 25 ppm and 44 ipm (images per minute, duplex) in black and white, grayscale and colour at 200 or 300 dpi. 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 (based on 20 lb, 75-80 g/m2 paper) document feeder for document widths up to 8.5" (216 mm). Long capability is supported up 38" (965 mm). 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.
