Scanner Drive
ˆ
The scanner motor drives a gear that turns a small drive belt. This drives the
scanner drive shaft.
ˆ
Pulleys on the ends of the shaft drive timing belts that drive the 1st scanner.The
first scanner is attached to timing belts, which drive the 2nd scanner with the 2nd
scanner's pulleys.
ˆ
When you scan in book mode, the 2nd scanner moves at half the speed of the
1st scanner. (Scanner speed is faster for reduction printing, and slower for
enlargement printing.)
ˆ
You can adjust magnification in the sub-scan direction with SP 4008. This will
adjust the motor speed.
ˆ
You can adjust the main scan direction with SP 4009
