■Fixed Thickness Mode
This unit scans while detecting the paper thickness and automatically adjusts the paper thickness setting. However, when scanning extremely thick or thin paper documents, the automatic adjustment may function less effectively, resulting in paper jams.
Paper jams in this instance can be prevented by setting the paper thickness to a fixed setting.
The paper thickness is set by “Manual Thickness Adjustment” (See “Manual Thickness Adjustment” P. 53).
Pressing the function key to which the “fixed thickness mode” is registered (default: function key 2) lights the function key lamp.
To return to automatic detection of paper thickness, press the key to which the Fixed Thickness mode is registered to turn the lamp OFF.
■Double Feed Detection
This scanner has a “double feed detection” function. This function memorizes the thickness and length of the first document sheet to be used as the standard document during continuous scanning, and automatically detects a double feed (simultaneous feeding of two or more pages), and displays an error when a double feed is detected.
Pressing the function key to which
To disable double feed detection, press the key to which double feed detection is registered to turn the lamp OFF.

MEMO
●As the first document sheet is used as the standard for detecting double feed, double feed may not be detected if the first document sheet is double- fed. Check the scanned image to see if the first document sheet was fed and scanned correctly.
●Double feed detection is not possible on documents having a width of 130 mm (5.1 in.) or less.
●A double feed is automatically judged and an error message displayed when an original 5 cm (2.0 in.) longer than the standard document or an original 1.5 times thicker or more than the standard document is detected.
●A double feed is automatically judged and an error code displayed when the stack of documents contains a document 5 cm (2.0 in.) or more shorter than the reference length.
●When the double feed function is set to ON by a function key, double feed is detected by both the document length and thickness. Detection of double feed by either document length or document thickness cannot be set to function keys.
Though this function can be set in the driver or the application, the function key does not light in this case. The function key lights when detection of double feed by both document length and thickness are both set.
●The double feed detection settings are reset when the power is turned OFF.
