Scanning Mechanism (Flatbed)
1. Scanning Mechanism
The Scanning Mechanism consisting of Lens, CCD PCB Assy (207), Mirrors, Xenon Lamp (204), Lamp
Base Bracket (224) and Mirror 2 Bracket (233), is used to scan originals.
• The Mirror 1 (264) and Mirrors 2 (265) 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 (202 & 203) driven by the Stepping Motor (201), move the Scanner
Assembly.
2. Transmit Mechanism
a. When ADF is used, originals are scanned on the Glass S (559). The Glass Assembly (557) is used
when scanning on the Platen.
b. The Scanning point is established by the Size Sensor 1 (270).
c. Document size is automatically set by the Original Size Sensor (1045) or 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 Stepping Motor (201) stops rotating and the Lamp Base and
Mirror 2 Brackets (224 & 233) return to the standby position.
During scanning, the Lamp Base Bracket (224) and Mirror 2 Bracket (233) 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 below. The location of these two brackets are established by the Size Sensor 1
(270) and the scanning length is established by the setting on the Touch Panel. The following illustrates
the Drive system.
