4-6Chapter 4 Other Functions3. User Mode FunctionsThe following functions are available in the User Mode.■ Separation Mode SettingIf double feeding or a paper jam occurs, change toSeparation Mode.HI: Use if friction between sheets is great, and you arefeeding documents that are difficult to separate.Normal: Use this setting normally.LO: Use when feeding fine documents.IMPORTANTOn [HI], as the separation power is great, the paper may tear. Ifthis happens, use [Normal] or [LO].■ Buzzer (Beeper) Control SettingThe beeper (“buzzer”) sounds when you press the controlpanel keys and when a scanning error occurs.ON2: The beeper sounds when a scanning error occurs,and when a control panel key is pressed.ON1: The beeper sounds when a scanning error occurs.OFF: The beeper never sounds.■ Double-Feed Control SettingSelect whether double feed detection is enabled when inCount-Only mode. If set to [ON], double feeds aredetected during feeding in Count-Only mode.There are two methods of double feed detection,comparing the length of documents and detectingunevenness between documents by ultrasonic sensors,which can be set according to the ISIS/TWAIN driver.(See p. 8-5)In Count-Only mode, double feed is set to be detected byultrasonic sensors.■ Staple Detection SettingSelect whether staple detection is enabled when the Count-Only mode is enabled.ON: Detects staples in the Count-Only mode.OFF: Does not detect staples in the Count-Only mode.Staple detection during scanning is set with the ISIS/TWAIN driver. (See p. 8-5)■ Staple Detection Level SettingSets the staple detection sensitivity level.[1] is the default setting, [2] provides higher sensitivity,and [0] provides lower sensitivity.
