the rotary switch settings and corresponding amount shifted.
1. Set the ADF on the scanner.

4. Open and then close either the paper eject cover or the paper feed
cover. (The EEPROM initialization and sensor adjustment mode is set
with this motion.)
5. Press the push button directly attached to the control board to run the
adjustment program, and EEPROM initialization and the sensor
adjustment for each sensor are carried out.
