Multifeed Detection
Your scanner has a selectable function that can alert you when a
multifeed occurs. A multifeed is when two or more documents pass
through the feeder simultaneously.
NOTE: The Scanner 3500 has a different multifeed detection setup
than the Scanner 3510, Scanner 3520, Color Scanner 3590C,
or Color Scanner 4500.
Enabling Multifeed
Detection for the
Scanner 3500
When enabled, this function causes an alarm tone to sound when a
multifeed is detected (alarm volume must be set higher than 0--see
Step 3).
When enabling multifeed detection, you can
• choose to detect a multifeed by length
• set the alarm volume
• choose whether scanning is to
- stop when a multifeed is detected
or
- continue with an audible alarm to indicate multifeeds
1. Select a number in the Length Detection box to set the length limit.
The Multifeed Stops Scanning check box is enabled.
2. Select the unit of measure (inches, millimeters, or pixels).
NOTE: Users of the ISIS-compatible device driver:
When defining a multifeed detection length limit, it is
recommended that you set the limit at least 0.7 inches (18 mm)
longer than the length of the documents you are scanning.
