Document stacker
  





2.1.1 Automatic document feeder (ADF)
If the operator sets documents on the stacker and starts the transmitting operation, the ADF
(consisting of the separation roller ASSY and ADF parts) feeds those documents into the
equipment, starting from the bottom sheet to the top, page by page. Each document ad-
vances to the scanner, and then it is fed out of the equipment with the white pressure roller.
