Fig.6.2

When scanning multipart paper with the Manual Feed Selector set to “AUTO”, the Double-feed Prevention Roller is
pressed against the Separation Roller, and this results in a separating force being applied to the document, which will separate
the layers, resulting in damage to the document.
This problem can be avoided by scanning multipart paper with the Manual Feed Selector set to "MANUAL".
The Double-feed Prevention Roller is retracted from the Separation Roller, and so the multipart paper can be fed
and scanned as if it were a single sheet of paper.
Note:

Do not scan multipart paper with the Manual Feed Selector set to “AUTO”.
When scanning multipart paper, be sure the Manual Feed Selector is set to “MANUAL”. 

Fig. 6.3

The Paper Feed Motor drives either the Paper Feed Roller mechanism or the Hopper lift mechanism depending on the direction
of its rotation.
The drive system is shown on Fig.6.3.
(a) The gear train (1) belongs to the drive system for the Paper Feed Roller and Separation roller.
(b) The gear train (2) belongs to the drive system for the Hopper Lift.
(c) The gear train (3) belongs to the drive system for the Paper Feed Roller, Separation Roller and Hopper Lift in common.

When the Paper Feed Motor rotates in the direction of the arrow A, the Paper Feed Roller is activated accordingly.
Conversely, when the Paper Feed Motor rotates in the direction of the arrow B, Hopper Lift Mechanism is activated.
The Gear trains marked with(*) are equipped with one-way clutches. Thus, rotation in one direction will drive the intended
gears but the opposite motion does not generate reverse movement.

1. The Hopper is mounted on the Lift Roller of the Hopper Lift Arm.
2. The Hopper Lift Arm is supported by the Hopper Cam through the Hopper Spring.
3. The Hopper Cam is an eccentric type cam, and is connected to the Hopper Lift Gear Train (Gear Train (2)) mentioned in Fig.6.3.
4. When the Hopper cam is in condition as shown in Fig.6.4.2, the paper can be set.
5. When the Hopper cam rotates in the direction of arrow as shown in Fig.6.4.3, it pushes up the Hopper Spring, and enables paper
    to be fed by attaching the Hopper to Paper Feed Roller.
6. The Hopper Cam continues to rotate until it goes to the position as shown in Fig.6.4.2 to let the Hopper go down.

1. When paper is set on the Flatbed Glass, and the scanning command is issued from PC, the Carriage Motor rotates to drive
the CIS Carriage.
2. After scanning the specified area, the Carriage Motor rotates in reverse, and the CIS Carriage returns to its home position.
