Excellent desktop scanner for bulk scanning. I have purchased over 40 of these over the years. They integrate well with TWAIN applications. Very good a dealing with different paper weights and sizes. Consumables are cheap (You will need to replace the feed rollers every 100k documents scanned). I cant comment on the bundles software as I don't use it. But the driver preforms very well. I have used them in terminal server environments, VDI environments and with thin clients with very good results.
What Panasonic have to say...
Reliable paper feed mechanism - Accurate processing of documents with various thicknesses
The paper feed rollers rotate independently left and right to reduce document
skewing during scanning.
The Active D ouble-Feed P revention Roller prevents double-feeding by reversing
rotation to separate documents that have stuck together,and then feeds the
leading document first
Document output control
The output speed is automatically lowered for documents that are 148 mm
or shorter, and the exit guides keep the document from slipping.
This stops longer documents from sliding under shorter ones to prevent the
output order from changing.
Advanced image processing & Improved scanning quality
The brightness and contrast of scanned images are automatically adjusted,
even on documents with varying paper colours and text hues, to produce scanned
images with suitable brightness.
Missing image detection and prevention
When a scanned image is missing due to an inadvertently folded corner
(dog-ear) or a document that is extremely skewed, scanning is automatically
and temporarily stopped. T he user can then decide to rescan, or to continue
scanning as is.
