ADF / Scanner mechanism
ADF mechanism overview
The ADF unit of this product supports up to A4/Legal size, and the CIS method using a color CIS module is adopted for document reading.
The document size is detected by the ADF document width sensor and the ADF document length sensor of the document support.
In addition, both sides of the document can be read using the CIS modules installed in the ADF mechanism and SCN mechanism.
ADF Paper Loading / Paper Feeding Operation
Documents loaded on the Document Support is released from the Set Guide by the drive force of the ADF motor, and then fed into the paper feed mechanism by the Roller (Pickup/ Retard/ Separation), 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 A4/Legal, three sensors (ADF Document Length Sensor 1, ADF Document Width Sensor 1/2) are mounted in the Document Support for document size detection.
