CCD Unit
Overview
The machine uses the CCD to expose and read an image and the image is read on a line-by-line basis.
CCD features 4 lines (R, G, B, B/W) and B/W line is used in B/W copy and R, G, B lines are used at color scan.
CCD overview
1. Integrated scanning configuration; CCD, lens, light source and mirror are integrated.
2. Light source: LED
3. Effective number of pixel: 7500 pix x 3 color lines, 7500 pix x 1 B/W line
4. Color filter: Colored filter (Red/Green/Blue)
[Optical path from LED]
The light generated from LED is reflected by an original and by the 5 mirrors. And then it is irradiated to the CCD through the lens.

Items | Description
CCD | Receives the reflected light that has gone through the lens and converts it into electric signal to output it.
Lens | Collects the light reflected by an original.
LED(light source) | Light source to expose an original to laser
Mirror No. 1 - 5 | Return the light
CCD PCB | CCD drive, analog image process, A/D conversion, A/D conversion, backup of the service mode about the reader and ADF
