3.3 SCANNER DRIVE

A five-phase stepper motor [A] drives the scanner. The 1st [B] and 2nd [C]

scanners are driven by this scanner drive motor [A] via 2 scanner wires. For

easyservicing, the wires at the front side and the rear side are the same.

In full size mode, the 1st scanner speed is 105 mm/s during scanning, and

720 mm/s when the scanner returns. The 2nd scanner speed is half that of

the 1st scanner.

In reduction or enlargement mode, the scanning speed depends on the

magnification ratio (M: 0.25 to 4.00) i.e., 105/M mm/s. The returning speed is

always the same (720 mm/s). The image length change in the sub scan

direction is done by changing the scanner speed, and in the main scan

direction it is done by image processing on the scanner IPU board.

The number of scans depends on the color selection mode as shown in the

following table:
