3.4 COLOR CCD
The color CCD converts light reflected from the original into three analog
signals, one for each of the three basic colors Red, Green, and Blue. The
signals are called the R, G, and B signals. Each of the four scans (for toner
colors BkCMY) uses all three signals (RGB).
The CCD consists of three lines of 5000 elements at a resolution of 400 dpi
(15.7 dots/mm). To make the R, G, and B signals, each line has a color
separation filter (R, G, or B).
The lines are spaced 8 pixels apart for full size magnification. To correct for
these spacings, the R, G, and B signals must be synchronized. This is done
by delay memories in the scanner IPU board (refer to the Image Processing
section).
The CCD is mounted on the board with the lens block (the assembly is
known as the SBU: Sensor Board Unit). Therefore, to replace the CCD,
replace the SBU.
