Paper Handling and Feeding
The input tray and automatic document feeder of the i780 Scanner is designed to stack and feed
up to 500 sheets of 75 g/m
sizes.
The feeder accepts a wide variety of paper weight, with no operator intervention necessary after
the initial loading. While the automatic document feeder works best with similar size documents, it
also handles the feeding of mixed document sets (batches) consisting of varying paper weight
and sizes in a reliable manner.
The feeder includes a gap release for the operator to easily bypass the separation feature when
feeding documents such as folders or envelopes.
Auto Orientation/Auto Rotation
For documents that contain mostly text, the scanner will analyze each document to determine
how it was fed and will rotate the image to the proper orientation at rated speed.
Ultrasonic Multifeed Detection
A reliable ultrasonic multi-feed detection system has been integrated into the i780 Scanner. Three
detection zones allow for greater feeding flexibility and can be independently enabled/disabled to
further customize and increase productivity of a scanning application. (left-, center-, and right-
edge) while still benefiting from multi-feed detection.
Sensors may be enabled or disabled, depending on your application. For example, if you know
that the right side of the document has a Post It
Multi-feed detection is enabled through the host software. Sensitivity levels (high, medium and
low) can be set to control how aggressively the scanner will work to determine if more than one
document is fed into the transport. Multi-feeds are triggered by detecting air gaps between
documents. This allows multi-feed detection to be used with applications containing documents
with mixed thicknesses.
• High sensitivity is the most aggressive setting and good to use if all documents are similar in
thickness of no greater than 75 g/m
• Medium sensitivity is the default and good to use if your application has varying document
thicknesses or labels attached to the documents.
• Low sensitivity is the least aggressive setting and is less likely to detect labels, poor quality
or wrinkled documents as multi-fed documents.
The operator can select either option when the system determines that multiple documents have
been fed through the scanner.
• Beep and Continue: beeps when a multifeed has been detected and will continue scanning.
• Beep and Stop: beeps when a multifeed has been detected and stops scanning. When this
occurs, the scanner will need to be re-enabled to resume scanning.
• Beep and Pause: beeps when a multifeed has been detected and pauses scanning. When
this occurs, the operator can quickly resume scanning by pressing the start button on the
scanner.
