6.4.2 SCANNER DRIVE
Book Mode
Scanner drive motor [A] and timing belt drive the scanner drive shaft [B]. The drive shaft
drives the pulleys attached to the two scanner wires [C] (front and back). The scanner wires
move the 1st and 2nd scanners [D] on their rails. The 2nd scanner speed is half that of the
1st scanner.
The scanner interface board (SIO) controls the scanner drive motor.
In reduction or enlargement mode, the scanning speed depends on the magnification ratio.
The returning speed is always the same, whether in full size or magnification mode. The
image length change in the sub scan direction is done by changing the scanner drive motor
speed, and in the main scan direction it is done by image processing on the BICU board.
Magnification in the sub-scan direction can be adjusted by changing the scanner
drive motor speed using SP4-008.
ADF mode
The scanners are always kept at their home position (the scanner home position sensor [E]
detects the 1st scanner) to scan the original. The ADF motor feeds the original through the
ADF. In reduction/enlargement mode, the image length change in the sub-scan direction is
done by changing the ADF motor speed. Magnification in the main scan direction is done in
the BICU board, like for book mode.
