HP Scanjet N8400 Scanner Series 
N8420 • N8460 
Easily scan, save, and manage documents, 
using a reliable flatbed scanner. 
Rapid duplex scanning 
Perform fast, single-pass, duplex scanning at speeds of 
up to 35 pages per minute (ppm) and 70 images per 
minute (ipm) with the HP Scanjet N8400 Scanner 
Series.
Improve workflow by creating up to 30 scan profiles 
for a variety of document types—such as paper size, 
file location, and more—using the included HP Smart 
Document Scan Software (SDSS). Assign four common 
profiles to one-touch buttons to instantly execute 
pre-assigned settings. 
Scan loan and mortgage documents, medical records, 
and ledgers using the legal-size flatbed scanner. And 
with HP dual-sensor technology, you’ll see scanned 
text clearly, and get excellent, 3-D detail in images. 
Enjoy the convenience of a copier—use the one-touch 
Copy button to send a scan to the default printer. 
Increase efficiency 
Confidently scan up to 1,500 pages per day with this 
robust scanner. Reliable HP technology ensures the 
scanner will work throughout the day, to give you the 
scans you need. 
Capture each page, every time you scan. If more than 
one sheet begins to feed, ultrasonic double-feed 
detection stops the scanner and notifies you to reset 
the paper in the automatic document feeder (ADF). 
Spend less time preparing documents for scanning, 
and see higher-quality results with Kofax® 
VirtualReScan®. Get clear scans at 200 dpi or scan at 
up to 600 dpi
Quickly turn stacks of hard copies into digital files, 
while you attend to other work. Just drop a stack of up 
to 100 legal-size sheets into the ADF, and press a 
button to begin scanning. 
Reduce start-up time and get your scans when you 
need them. Patented HP technology keeps the lamp 
warm and ready to scan.

management tools (see page 3 for more information).

included Scansoft® PaperPort® software. Convert 
scans into editable text, with the power and accuracy
