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 equipment,
starting from the bottom sheet to the top, page by page. Each document advances to the scanner
with the LF roller, and then it is fed with the document ejection roller.
