1

Used to perform copy magnification ratio adjustment (main/sub scanning 
direction).

RSPF/Scanner

Adjustment

5

This adjustment is executed when a satisfactory result is not obtained when a 
different copy magnification ratio is specified and copying is made after 
adjustment of the sub scanning direction image magnification ratio with SIM 48-
1.
When there is an error in the copy magnification ratio in reduction copy, the 
adjustment value of high speed mode is adjusted.
When there is an error in the copy magnification ratio in enlargement copy, the 
adjustment value of low speed mode is adjusted. This is the magnification ratio 
adjustment in the scan system.
