10.9 Functions of SCANNER ASSY
10.9.1 Document Scanning
The SCANNER ASSY consists of the Image Input Terminal (IIT) and the Duplex Automatic Document Feeder
(DADF). Document scanning is performed by the Carriage Assy in the Image Input Terminal.
10.9.2 Document Scanning at Platen (IIT)
The Carriage Assy consists of the LED Array for illuminating a document, the CCD Image Sensor for photo
electronic converting image data, the mirrors, and the lens.
By the drive from the Carriage Motor, the Carriage Assy in the IIT moves at the shifting speed corresponding
to the set magnification and irradiates the document by the LED array. The optical image of the document irra-
diated by the LED array is reflected by the multiple mirrors, passed through the lens, and then scanned by the
CCD Image Sensor.
