Scanner Moving Mechanism

• The Scanner is driven by the Scanner Motor at a speed according to the set zoom ratio
calculated with reference to the speed of the full size mode.
• The Scanner is detected at its home position by Scanner Home Position Sensor 1.
• Scanner Home Position Sensor 2 determines the home position of the Scanner when the
AF-9 is used.

• The 2nd/3rd Mirrors Carriage travels at a speed half that of the Scanner, thereby keeping
constant the optical path length between the original and PC Drum.
