Mechanical Operation
6.1.1.
Scanning Mechanism (Flatbed)
1. Scanning Mechanism
The Scanning Mechanism consisting of Lens, Color CCD PCB Assembly, Mirrors, Scanner Lamp,
Lamp Base Bracket, and Mirror 2 Bracket, is used to scan originals.
• The Mirror 1 and Mirrors 2 reflect image information, in the form of light, through the Lens.
• The Lens focuses the image information, and passes it to the Color CCD.
• The Color CCD, mounted on the Color CCD PC Board, converts the image information into an
electrical signal.
• The Timing Belt and Driving Wire are driven by the Stepping Motor, moving the Scanner Assembly.
2. Transmit Mechanism
a. When i-ADF is used, originals are scanned on the ADF (S) Glass. The Platen (L) Glass is used
when scanning on the Platen.
b. The Scanning point is established by the setting on the Panel, or by an Automatic Document Size
Detection Sensor.
c. Document size is manually set when the Platen is used, or is set automatically by the Document
Size Detection Sensor.
d. The Transmit Mechanism starts feeding, and scanning originals based on the above Document Size
Setting.
e. When scanning is completed, the Stepping Motor stops rotating, and the Lamp Base and Mirror 2
Brackets return to the standby position.
During scanning, the Lamp Base Bracket and Mirror 2 Bracket move in the direction of the Black arrow,
and while returning to standby position, it moves in the direction of the White arrow as shown in the
illustration. The location of these two brackets, and the scanning length are established by the setting
on the Panel. The following illustration shows the Drive system.
