Magnification in Sub Scanning Direction
To vary the magnification of sub scanning direction, the machine operates as below depending on the original reading methods and the magnifications.
1) Magnifications in book mode
To suite the selected rate of magnification, the machine changes the speed of original reading and executes data processing on main controller PCB 2.
e.g.) Reduction to 25%: an original is read at 260mm/s, and the data is processed for 25% reduction (skipping for 4/1) by the main controller PCB 2.
e.g.) at 100%: an original is read at 260mm/s.

Operation | Magnifications
25% to 50% | 50.1% to 199.9% | 200% to 400%
Speed change of original reading (mm/sec) | 260 | 260 | 130
Digital magnification process (%) on the main controller PCB 2 | 25 to 50 | 50.1 to 199.9 | 100 to 200

2) Magnifications in ADF mode
To suite the selected rate of magnification, the machine changes the speed of original reading and executes data processing on main controller PCB 2.
e.g.) Reduction to 25%: an original is read at 260mm/s and the data is processed for 25% reduction (skipping 4/1) by the main controller PCB.
e.g.) Enlargement to 200%: an original is read at 130mm/s and the data is processed for 100% direct reproduction by main controller PCB.

Operation | Magnifications
25% to 50% | 50.1% to 199.9% | 200% to 400%
Speed change of original reading (mm/sec) | 260 | 260 | 130
Digital magnification process (%) on the main controller PCB 2 | 25 to 50 | 50.1 to 199.9 | 100 to 200
