# ADF mechanism

The ADF mechanism of this product is composed of the Paper loading mechanism and the Paper feed mechanism. The CIS Module on the fixed scanner mechanism and the CIS Module on the ADF mechanism read both sides of the document at the same time.

#Operation during the ADF paper loading/paper feeding

Documents loaded on the Document Support is released from the Set Guide by the drive force of the ALD Motor, and then fed into the paper feed mechanism by the ADF Separation Roller Assy and the Acceleration Roller. The retard separation method is used for paper separation, and each document is separated by the ADF Retard Roller. To support document feeding up to A3/Ledger, four sensors are mounted in the Document Support for document size detection.

The paper is loaded/fed while stopping the Register Roller. These status is kept for a certain period of time after the paper reaches the Register Roller to bend the paper during the skew correction.
