1. Scanning Mechanism
The Scanning Mechanism consisting of Lens, CCD PC Board Assembly, Mirrors (551,552), Scanner
Lamp (501), Lamp Base Bracket (516) and Mirror 2 Bracket (525), is used to scan originals.
• The Mirror 1 (551) and Mirrors 2 (552) reflect image information, in the form of light, through the Lens.
• The Lens focuses the image information and passes it to the CCD.
• The CCD, mounted on the CCD PC Board, converts the image information into an electrical signal.
• The Inner and Outer Timing Belts (502 & 503) driven by the Scanning Motor (131), move the Scanner
Assembly.
2. Transmit Mechanism
a. When ADF is used, originals are scanned on the Glass S (116). The Glass L Assembly (117) is used
when scanning on the Platen.
b. The Scanning point is established by the Photo Sensor (554) for Size.
c. Document size is manually set when the Platen is used.
d. The Transmit Mechanism starts feeding and scanning originals based on the above Document Size
Setting.
e. When scanning is completed, the Scanning Motor (131) stops rotating and the Lamp Base and
Mirror 2 Brackets (516 & 525) return to the standby position.
