2.1 Transmitting Mechanism (Feeding and scanning documents)
The transmitting mechanism consists of the document stacker, automatic document feeder
(ADF), document feeding related rollers, scanner, and document sensors. (For details about
the sensors, refer to Section 2.4.)
For the drive power source, refer to Section 2.3.
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 and ADF parts) feeds those documents into the equip-
ment, starting from the bottom sheet to the top, page by page. Each document advances to
the scanner, and then it is fed with the white pressure roller and document ejection roller.
