Product Technical Overview
DADF Scanning
In the DADF mode, the carriage is positioned under the constant velocity transport (CVT)
glass. The carriage remains stationary while the document is moved across the CVT glass by
the DADF.
The stationary half rate and full rate mirrors are used in the usual way to reflect the image
through the lens to the CCD.
In all copy modes, the document is only scanned once regardless of the number of copies
required. Refer to Figure 6.

Image Flow
The image data from the CCD image sensor are sent to the ESS PWB via the CCD ribbon
cable. Shading compensation and white and black correction are then applied to the image
data. Refer to Figure 7.
