The magnification ratios in the main scanning direction (front/rear) and in the sub scanning direction are adjusted.
Enter the adjustment value with 10-key, and press START key to save the entered value, and make a copy. (When the set
value is increased by 1, the magnification ratio is increased by 0.1%.)
The adjustment mode can be selected with the density select key. (Adjustment range: 1 – 99, Default: 50)
05 The current SPF mode sub scan direction magnification ratio is displayed on the LCD/7seg.
When START key is pressed, the entered data are obtained and saved into the EEPROM, and a copy is made. (When the set
value is changed by 1, the ratio is increased by 0.1%.) (Set range: 1 – 99, Default: 50)
