The lens focuses the image from the scanned original onto the CCD through
the 1st, 2nd, and 3rd mirrors. The 1st carriage [A] which contains the xenon
lamp [B] and 1st mirror [C], moves from X to Y to scan the original vertically.
The 2nd carriage [D], which contains the 2nd [E] and 3rd [F] mirrors, moves
to keep the distance between the document and the CCD constant.
3. Scanner Reversing
After the image has been scanned, the carriages return to the home position.
The carriages are stopped when the first carriage activates the home position
sensor. If the scanner home position sensor is not activated within a certain
time, a home position sensor error will occur.
