HP Scanjet N9120 Reviewers’ Guide
The new HP Scanjet N9120 Document Flatbed Scanner offers fast, unattended scanning
with time-saving productivity features. With a duty cycle of 5,000 pages per day, this
robust, reliable machine is ideal for customers seeking a dedicated departmental document
management scanner.
Save time with rapid scan speeds and a 200-page ADF
The HP Scanjet N9120 offers fast, precise dedicated document scanning - up to 50 pages
per minute (ppm) and 100 images per minute (ipm) in black and white, greyscale or colour
at 200 dpi, using the 200-page automatic document feeder (ADF).3
The ADF automatically pulls documents through the scanner for convenient, unattended
scanning. Simply drop a stack of documents - up to 200 pages - in the ADF and press a
button to scan the entire stack while you attend to other work. The ADF features automatic
duplexing for quick, easy scanning of large scan jobs. Dual scan heads simultaneously scan
both sides of the page in a single pass, so you can save time and increase productivity.
Customise scanned documents
The scanner features an integrated ink imprinter4 to
help you accurately track scanned hard-copy
documents. The integrated imprinter allows you to
customise scanned hard-copy pages by printing a
page number, character string, or distinguishable
mark on the back of the scanned page. Vertical
print capabilities are programmed to support date,
time, document count, and custom messages - up to
40 characters. The imprinter features are easily
accessible through included ISIS and TWAIN
drivers (see Easy Integration for more information).
Reliably scan every page
The HP Scanjet N9120 uses ultrasonic double-feed detection to reliably scan each and
every page. The scanner stops when a double feed (two or more pages) is detected and
notifies you to reset the paper in the automatic document feeder. There’s no need to double
check - when the scan is complete, you can feel confident every page has been captured.
Built-in hardware page rotation saves time by eliminating the need to manually rotate hardcopy pages. The scanner allows for rotation in the hardware, so you get the results you
expect while maintaining fast A4 scanning.
Speeds attained by using 200 dpi monochrome, greyscale or colour modes with A4 paper in landscape mode using
hardware compression.
The integrated ink imprinter requires an optional HP ink cartridge. Not included, sold separately.
HP Scanjet N9120 Reviewers’ Guide
Quickly complete common scanning tasks
The HP Scanjet N9120 has two Quick Start buttons on the front control panel which allow
for quick scanning startup. The Scan button launches the HP Smart Document Scan Software
where you can select a profile to scan from, or start a scan using the HP Smart Document
Scan Software profile assigned to the button. You can easily produce single or multiple
copies of scanned documents or images using the dedicated Copy button and an existing
default printer—the copies go directly to the default printer assigned to the PC connected to
the scanner.
NOTE: The PC must be powered on and an existing printer selected to create a copy from a
scanned document or image.
Additional buttons automatically launch specific tasks:
Cancel - Cancels a scan or copy job in progress.
Tools - Launches the HP Scanner Tools Utility where you can associate the scanner Quick
Start buttons with scanning software, get status information, maintain the imprinter, and
view information on scanner settings and maintenance.
Attention LED - Provides status information about the scanner.
Power Save - Turns off the lamp and places the scanner in Power Save mode (saves energy
when the scanner is not in use). When you are ready to begin scanning again, press the
Power Save button to wake up the scanner (see Start scanning jobs faster).
Selecting scan profiles
Scanning profiles provide a fast, efficient way to scan. You can configure settings for
numerous profiles for specific, frequently used scanning functions. Profiles describe the scan
settings, profile options, and destination of the scanned document, such as a SharePoint
portal, FTP, Microsoft® Word, or others. You can create customised scan profiles using the
included HP Smart Document Scan Software - then assign the profiles to Quick Start buttons
on the control panel where you can easily launch them. See the onscreen Help for details.
The HP Smart Document Scan Software includes a set of predefined scan profiles for typical
scanning tasks. You can create new profiles, as well as modify, upgrade, delete or restore
profiles at any time. See the HP Smart Document Scan Software onscreen Help for details.
HP Scanjet N9120 Reviewers’ Guide
Start scanning jobs faster
HP’s proprietary Instant Lamp-on scanning technology keeps the scanner lamp warm and
stable so the Scanjet N9120 is always ready to scan. This innovative technology reduces
start-up time when the scanner bulb has been turned off.
High-quality results
HP scanners feature technology that delivers an optimal combination of scanning resolution
and performance for fast, high-quality scans. You can easily adjust the resolution to fit any
job. Scan documents in low resolutions to get the smallest file size, or scan with higher
resolution (up to 600 dpi) for better image quality. For getting the best image from difficult
documents such as those with coloured backgrounds, the HP Scanjet N9120 includes Kofax
VirtualReScan® (VRS®) Professional software. The Kofax VRS Professional software is easily
utilised simply by checking a box in the “Scan” section of a scanning profile in the HP
Smart Document Scan Software.
Note: The Scanjet N9120 speed specifications of 50 ppm/100 ipm are based upon
scanning at 200 dpi. Selecting higher quality settings increases the time it takes to capture
a scan.
HP Scanjet N9120 Reviewers’ Guide
Reliably scan a variety of paper sizes
The HP Scanjet N9120 accommodates a
variety of hard-copy documents, from A6 to
A3-sized media, including index cards,
questionnaire forms, surveys, medical
records, mortgage documents, ledgers,
magazines and more. The scanner captures
A3-sized documents through the ADF or the
flatbed scan surface. The automatic
document feeder accepts varying paper sizes
from 70 – 300 mm wide and 148 – 864 mm
The A3-size flatbed can be used for scanning items such as thin paper, excerpts from thickbound materials and books, and worn or stapled documents that cannot be sent through the
automatic document feeder.
A hardware deskew feature straightens pages prior to scanning, reducing the likelihood of
documents becoming skewed or slanted during scanning.
Changeable ADF black and white backgrounds
The Scanjet N9120 allows you to easily switch back and forth between black or white
backgrounds to enhance the readability of scanned documents. The black background
improves image quality and allows software applications to better distinguish the edges of
scanned pages. The white background minimises the appearance of the outside edges of
scanned pages in digital files. See the HP Scanjet N9120 User Guide or the onscreen Help
for details.
Colour channel filter
A multicolour drop-out feature allows you to remove up to three distinct colours from
scanned documents or images. You can filter out a colour channel (red, green or blue) or
up to three specific colours from a scanned image, such as removing coloured lines from a
questionnaire form. This feature is useful for filtering out dark backgrounds from the image
content, for example, black text on green paper or red instructions on a form to enhance
readability. Removing colours from scans can improve the accuracy of optical character
recognition (OCR) or intelligent character recognition (ICR) results and reduce the size of
scanned files.
HP Scanjet N9120 Reviewers’ Guide

test with the ultrasonic double-feed detection feature disabled.
NOTE: The ultrasonic double-feed detection feature remains “on” until disabled in the
HP Scanjet N9120 Reviewers’ Guide
Evaluating scanning features
As you answer the following questions, consider the end-user’s needs. With the use of
document scanners - formerly limited primarily to scan technicians - now encompassing
individuals in a variety of business environments, ease of use becomes a particularly
important factor.
Does the device have a set of useful features?
Does it have productivity features such as switchable backgrounds, double-feed
detection, imprinters, etc.?
What productivity software is included? Does it include Kofax VRS?
How easy is it to learn and remember how to accomplish tasks? Do you need to open
different software to accomplish different tasks, or to see what settings to use?
Consider how well the feature set meets the needs of customers (business users and
users in large enterprise organisations).
How well does the product design fit its intended market?
Does the device support a variety of paper types, weights, and sizes?
How easy is it to select a specific application to send scanned documents, or to change
selections or scan settings?
How easy is it to create copies with a default printer?
Evaluating the capture software
As you evaluate the scanning software interface, consider the following:
Is the software easy to install and use?
How easy is it to perform basic tasks such as scanning documents and saving to PDF,
making a copy, and scanning to email?
Does the software provide a quick, easy path from capturing a document to archiving
it, or sharing it in an electronic format?
How easy is it to change default settings or select a different application to send
scanned documents?
Evaluating scanning performance
Scanners are often ranked by the number of pages per minute (ppm) scanned. This
indicator, somewhat like horsepower in a car review, gives some guidance but does not tell
the entire story. Scanning speeds are only one part of the time it takes to get a document
into a scanned file for archiving or sharing. The combination of scan features, such as the
time it takes to achieve common scanning tasks, software interface, paper handling
capabilities and overall ease of use, including training, must fit your needs to make your
project a success - regardless of the scanner’s speed rating. Also consider which ISV
applications the scanner works with.
As you perform each scan job, note the length of time it takes to complete each scan.
Consider the time to achieve a complete task, not just the scan.
The task buttons on the HP Scanjet N9120 control panel can help save time and
increase productivity with the capability to start common scan tasks simply with the
press of a button.
HP Scanjet N9120 Reviewers’ Guide
Evaluating scanning performance, continued
Consider integration of scanning applications with other common applications,
including innovative ways to eliminate steps and ease integration.
The HP Scanjet N9120 can be integrated with ISIS/TWAIN/WIA compliant
applications with the included ISIS, TWAIN and WIA drivers so you can set up the
scanner and begin scanning immediately.
The HP Smart Document Scan Software can also be used to integrate the scanning
application with third-party applications through the application link in the destination.
HP works with leading document management software vendors to make sure their
applications are compatible with HP products. See www.hp.com/go/gsc for a
complete listing of certified applications.
Other factors, such as the rate of data transmission from the scanner to the computer
are also important to consider.
The HP Scanjet N9120 supports Hi-Speed USB 2.0 for optimal data transmission
Ease of use is also an important attribute when considering overall scanning
performance. The speed of a very fast scanner may be negated by unintuitive or
cumbersome software, needing to utilise multiple applications to complete a task, or
confusing scanner controls.
Measuring scanning speed
There are many ways to measure speed. The quoted speeds for the HP Scanjet N9120 are
derived from common industry methods that measure typical scanning speeds without
influences such as software startup times, computer performance, lamp warm-up time from a
cold state, etc. The method below describes the process HP uses for measuring its quoted
Speeds are measured after machine warm up and application is initiated
The quoted speed is measured from the first page scanned to the last page ejected
using a 50-page stack size
Application used is HP Smart Document Scan Software
The system must meet recommended system requirements
Other applications running on the system may impact experienced scan speeds
Evaluating scan quality
Compare the quality - text, mixed text and colour graphics - of scanned documents with
scanned output from other comparably priced scanners. Again, it is important to consider a
combination of features, such as scanning performance, software interface, and overall
ease of use when making quality comparisons.
HP provides Kofax® VirtualReScan® Professional software to help the customer get the best
scan quality with difficult documents.
