AR-M550/M620/M700  DETAILS OF EACH SECTION  6 - 91
C. Operational descriptions
(1) CCD/lens unit
This machine employs the reduction optical-type line CCD (Charge
Coupled Device) of scan resolution of 600dpi and 7400 pixels.
CCD scan is performed by shifting the scan positions sequentially by the carriage unit (lamp and mirror) scan or moving the document with the SPF.
Lights reflected by the document are reflected by each mirror to form images on CCD elements through the reduction-type lens. The CCD converts the
optical energy into electrical energy (analog). (Photoelectric conversion)
(2) CIS unit
The image sensor which scans back document images is attached to the SPF. The close-contact type image sensor (Contact Image Sensor) with
scan resolution of 600dpi and 7196 pixels is employed.
For the CIS to scan documents, the scan position is sequentially shifted by shifting the document by the SPF, and the LED light in the unit is radiated
to the back of the document, and photo energy is converted into electric energy (analog signal).
(3) Image signal flow
The image signal converted into electric energy (analog signal) is A-D
converted on the CCD PWB. Image processes such as white balance
and shading correction are performed on the scanner control PWB.
The image signal is then sent through the mother board to the MFP
control PWB.
In the MFP control PWB, image process is performed according to the
setting content of the operation panel. The image data are converted
into laser lighting signals (VIDEO signals), and sent through the mother
PWB and the PCU to the LSU (Laser Scan Unit). 
In the LSU, the VIDEO signals are converted into laser beams, which
are radiated onto the drum.
