Before loading documents, make sure that the ADF access doors are securely latched.
When loading a stack of documents, make sure that all of the documents are the same size.
The maximum capacity of the ADF is 200 sheets of 75 g/m2 (20 lb) paper. When using heavier paper, the
maximum capacity is decreased. Use the fill line, shown below, as a guide for the maximum height of the
document stack.

Load original documents

Chapter 1

•

For small or narrow documents, load the edge that is less than 148 mm (5.8 in) pointing into the feeder so
that the longer edge can be pulled into the feeder and passed along by the feed rollers.

•

When loading small or lightweight documents, such as A6 cards (index cards) or U.S. check carbons, load a
stack of at least five documents to ensure that the ADF properly detects and feeds the stack. When
scanning fewer than five small or lightweight documents, scan the documents by placing them on the
scanner glass.
When loading long documents that hang over the end of the input tray, pull out the input tray extender (1),
and then load the documents (2).

•

How to load documents
1.

Flip up the paper stop in the output tray that best matches the size of the documents that you are scanning.
Select the stop position that is closest to (and beyond) the edge of your documents as they come out of the
automatic document feeder (ADF).

Use the scanner

Fan the stack of document pages to ensure that the pages do not stick together. Fan the edge that will be
pointing into the ADF in one direction, and then fan that same edge in the opposite direction.

Align the edges of the documents by tapping the bottom of the stack against the table top. Rotate the stack
90 degrees and repeat.

Place the stack in the middle of the input tray. Load the stack face up. For fastest scanning, load the stack
with the left edge leading into the ADF.
NOTE: In the scanning software, choose the layout setting that matches the orientation of the originals
in the ADF.

Adjust the paper guides to the width of the documents. Take care not to overtighten the guides, which can
restrict paper feeding, but make sure that the paper guides touch the edges of the documents.
Load original documents

Chapter 1

Gently push the stack forward to trip the tray sensor.

Load an original on the scanner glass
Place items that do not meet the specifications for the automatic document feeder (ADF) directly onto the

Automatically rotate scanned pages
By default, pages fed through the automatic document feeder (ADF) appear in the scan output in the same
orientation as the pages in the ADF input tray. The scanner can rotate the scan data to produce a different
orientation in the scan output. For example, this feature is useful when you want fast scanning of pages that have
a portrait orientation. You can load the longer edge of these pages into the ADF input tray and obtain scan output
with the shorter edge of the pages at the top of the image.
To enable scanned page rotation in an HP Smart Document Scan Software profile, follow these steps:
1.
2.
3.

Open the HP Smart Document Scan Software.
Select a scan profile, and then click Edit.
On the Layout tab of the Profile Settings dialog box, select the appropriate options for Original Layout
and ADF Feed Direction.
NOTE: In other scanning software, the options for rotating pages are on the Layout tab of the ISIS or
TWAIN Advanced Settings dialog box.

Scan extra long documents
By default, the automatic document feeder (ADF) accepts a stack of originals up to 300 x 432 mm (11.8 x 17 in).
You can choose to scan pages up to 300 x 864 mm (11.8 x 34 in) through the ADF.
To enable long-page scans in an HP Smart Document Scan Software profile, follow these steps:
1.
2.
3.

Open the HP Smart Document Scan Software.
Select a scan profile, and then click Edit.
On the Layout tab of the Profile Settings dialog box, select Custom in the Size drop-down list, and then
type the actual page dimensions, up to 300 x 864 mm (11.8 x 34 in), in the Width and Height boxes.
NOTE: 1 In other scanning software, the page size settings are on the Layout tab of the ISIS or TWAIN
Advanced Settings dialog box.
NOTE: 2 Some scanning and destination software (including the Kofax VirtualReScan driver) might not
support all of the page sizes that the scanner accepts.
NOTE: 3 HP recommends scanning long pages individually at a resolution of 300 dpi or lower.

Filter out color from a document (color dropout)
You can filter out a dark background from the image content, for example black text on green paper or red
instructions on a form. Removing colors from the scan might reduce the scan file size and improve optical
character recognition (OCR) results. You can select to filter out a color channel (red, green, or blue) or up to three
specific colors. For specific colors, the sensitivity setting controls how closely a scanned color must approximate
the specified color.
To select colors to eliminate from a scan in an HP Smart Document Scan Software profile, follow these steps:
1.
2.
3.
4.

Open the HP Smart Document Scan Software.
Select a scan profile, and then click Edit.

filters apply to all color modes.
NOTE: 2 To filter out color in another scanning software, navigate to the ISIS or TWAIN Advanced Settings
dialog box. On the Color Dropout tab, specify the color dropout settings.

Useful scanner features

Set the background color for scans from the automatic
document feeder
When you scan from the automatic document feeder (ADF), you can choose a white or black background for the
scan. When the scan background contrasts with the color at the outside edges of the document, the scanning
software is better able to distinguish the edges of the scanned document. For example, use the black background
to scan a document that is printed on white paper.
To select the scan background color in an HP Smart Document Scan Software profile, follow these steps:
1.
2.
3.
4.

Open the HP Smart Document Scan Software.
Select a scan profile, and then click Edit.
On the Scan tab of the Profile Settings dialog box, click Advanced Settings.

Scan files are too large
If the saved scans have very large file sizes, try the following:
•

•
•
•

Verify the scan resolution setting:
◦
200 dpi is sufficient for storing documents as images.
◦
For most fonts, 300 dpi is sufficient for using optical character recognition (OCR) to create editable
text.
◦
For Asian fonts and small fonts, 400 dpi is the recommended resolution.
Scanning at a higher resolution than necessary creates a larger file with no additional benefit.
Color scans create larger files than do black and white scans.
If you are scanning a large number of pages at one time, consider scanning fewer pages at a time to create
more, smaller files.
Use the Kofax VirtualReScan software to process the scanned data. Kofax VirtualReScan compresses the
data, which can result in a smaller file.

The imprinter is not printing or the print quality is poor
If you reset the ink level in the HP Scanner Tools Utility the last time that you replaced the print cartridge, you will
receive imprinter status alerts when the ink level is running low. If you did not reset the ink level at the time that
you replaced the print cartridge, you might receive erroneous imprinter status alerts or the imprinter might run out
of ink before the HP Scanner Tools Utility reports that the ink level is low.
NOTE: To use the imprinter, load originals in the automatic document feeder (ADF). The imprinter cannot
print on pages placed on the scanner glass.
To remedy other imprinter problems, try the following:
1.
2.

3.
4.
5.

Verify that the Enable Imprinting check box is selected in the scanning software.
If the imprinter ink is smearing or leaving blobs of ink on the paper, remove the print cartridge, and then
gently wipe the copper contacts of the print cartridge with a clean, damp, lint-free cloth. Reinstall the print
cartridge, but do not reset the ink level in the HP Scanner Tools Utility.
Verify that the cartridge stall latch holds the print cartridge firmly in place.
Verify that the imprinter is positioned at one of the predefined locations that is inside the width of the paper
as it is fed through the ADF.
Clean and test the imprinter:
a.
Press the Tools ( ) button on the scanner front panel to open the HP Scanner Tools Utility. Click the
Imprinter tab, and then click Clean Imprinter.
b.
Ensure that the ADF has at least one piece of paper in the input tray.
c.
In the HP Scanner Tools Utility, click Test Imprinter.
d.
If the imprinter print quality is good, continue scanning. Otherwise, replace the print cartridge.
