Multifeed Detector
The multifeed detector picks up an ultrasonic signal that determines when there is more
than one sheet of paper entering the scanner.
NOTE:
Some documents, such as folded card stock, laminated documents, or labels/sticky
notes, may trigger the multifeed alarm. You can prevent unwanted multifeed alarms by
setting the multifeed ignore by size. Please refer to Section 5.3.3.5, Setting the
Multifeed Ignore by Size of this manual for more information.
If the scanner detects a multifeed, remove the documents held in the exit rollers and
unscanned documents in the exit tray, place them in the feeder, and then press the
CLEAR button to continue scanning.
If you wish to ignore the multifeed alarm, press the MULTIFEED IGNORE button if the
multifeed detection is set to STOP. After a multifeed is detected and the MULTIFEED
IGNORE button is pressed, the multifeed detection returns to STOP on multifeed.

Document Skew
Document skew occurs when a document enters the scanner at an angle. Skew happens
for several reasons:
• Documents are poorly prepared (not neatly stacked).
• Document guides are not properly adjusted.
• There is dust buildup on the feeder rollers. The feeder rollers should be cleaned to
solve this problem. Refer to Section 6.8, Cleaning the Transport Area .
• The transport is not fully closed.
NOTE:
The scanner's automatic de-skew capability through VRS can compensate for
document skew. Please refer to the skew section in the Kofax VRS User Manual for
more detail.

Clearing Scanner Document Jams
Follow the directions below to clear a document jam:
1. If a jam occurs, the scanner might stop itself. If the scanner does not stop, press the
STOP key on the scanner control panel or the application software.
2. Open the transport using the opening handle on the lower right side of the control
panel.
