2.General:
3.Action:
SF-2050 / 2052 / 2150
Since the ADU drawer spring is so long as to impair the workability during assembly, it is
changed with the shorter spring in order to improve the productivity.

2.General:
SF-2052 / 2150 : 1st mass production
3. Change of front cover/tray cover fastening screws (productivity improvement)
SF-2050 / 2052 / 2150
Since there is not any margin between the installation hole of the front cover and tray
cover and the head of the screw, the head of the screw is sometimes sunk during
production when the screw is tightened with motorized driver, etc. Therefore, the screw is
changed as the countermeasure.
