Select a profile whose page loading selection matches the edge you are feeding first.
◦
Scanning the following types of documents with the ADF might result in paper jams or damage
●
to the documents. To scan these documents, use the scanner glass instead of the ADF.
Wrinkled or creased documents Curled documents
Torn documents Documents with paper clips or
staples
Carbon paper Coated paper
Extremely thin, translucent paper Paper with adhesive notes or flags
attached
Load originals 7
Photos Overhead transparencies
Papers that are stuck together Paper with wet substances such as
glue or correction fluid
Smooth out any folds or curls in your documents before placing them into the feeder. If the
●
leading edge of a document is curled or folded, it may cause a paper jam.
When loading paper that is smaller than 148 mm (5.8 in) in width, place the long edge of the
●
page parallel to the paper guides.
To scan fragile documents (such as photos or documents on wrinkled or very lightweight paper),
●
place the document face down on the scanner glass.
Make sure that the hatch on the document feeder is securely latched. To properly close the
●
hatch, press until you hear a click.
Adjust the paper guides to the width of the documents. Make sure that the paper guides touch
●
the edges of the original. If there is any clearance between the paper guides and the edges of
the documents, the scanned image might be skewed.
When placing a stack of documents into the feeder, gently set the stack in the document feeder.
●
Do not drop the stack into the feeder.
TIP: The document load/detect LED on the clear portion of the document feeder input tray is
on when documents are positioned correctly.
To prevent skewing, always load stacks of documents of the same dimensions. However, if you
●
must load stacks of mixed document sizes, center all documents in the stack by width before
inserting them in the document feeder.
Clean the scanning rollers if the rollers are visibly dirty or after scanning a document that has
●
pencil writing on it.
How to load documents
1. Adjust the paper guides to the width of the documents. Take care not to overtighten the guides,
which can restrict paper feeding.
When scanning small originals such as checks, it is especially important that the paper guides fit
snugly against the edges of the original.
8 Chapter 2 Use the scanner
2. Fan the stack of document pages to ensure that the pages do not stick together. Fan the edge
that will be pointing into the feeder in one direction, and then fan that same edge in the opposite
direction.
3. Align the edges of the documents by tapping the bottom of the stack against the table top.
Rotate the stack 90 degrees and repeat.
4. Gently set the stack in the document feeder. Load the pages face up with the top of the pages
pointing into the feeder.
For best results, do not drop the stack into the feeder and do not tap the top edge of the stack
after you have placed it in the document feeder.
TIP: Avoid feeding a document with a leading edge that has been folded or frayed. When you
begin scanning, select a profile whose page loading selection matches the edge you are feeding
first to ensure that the scan reflects the orientation of the original document.
5. Verify that the paper guides are aligned with the edges of the stack.
Use the scanner glass
Place items that do not meet the specifications for the automatic document feeder (ADF) directly onto
the scanner glass.
Minimum size: No minimum size
Maximum size: 216 x 356 mm (8.5 x 14 in)
Load originals 9
NOTE: Not all the length of the scanner glass is in the active imaging area, so make sure to position
your originals as indicated by the reference mark on the edge of the scanner glass.
Place the original face down on the scanner glass, as indicated by the reference mark. For landscape
pages, place the page face down with the top of the page pointing toward the back of the scanner.
TIP: To scan multiple pictures at the same time, arrange the pictures that you want to scan on the
scanner glass with at least 6 mm (0.25 in) of space between items.

NOTE: Use the ISIS or TWAIN user interface to set the page size when scanning from third-
party applications.
NOTE: Some scanning and destination software might not support all of the page sizes that
the scanner accepts.
NOTE: HP recommends scanning long pages individually at a resolution of 300 dpi or lower.
16 Chapter 3 Useful scanner features
Reduce file size with hardware compression
The scanner supports multiple levels of JPEG compression to increase the rate of data transfer from
the scanner to the scanning software on the computer. The scanner compresses the data during the
scanning process. The scanning software can uncompress the data in order to create scanned
images. JPEG compression works on grayscale and color scans.
To enable JPEG compression in an HP Smart Document Scan Software profile, follow these steps:
1. Open the HP Smart Document Scan Software.
2. Select a scan profile, and then click Edit profile.
3. On the Scan tab of the Profile Settings dialog box, click Hardware Options.
4. Use the Data transfer slider to set the level of compression.
Higher quality turns off compression, resulting in slower data transmission.
●
Lower quality turns on compression, resulting in faster data transmission.
●
NOTE: Use the ISIS or TWAIN user interface to control compression when scanning from third-
party software.
Reduce file size with hardware compression 17
Filter out color from a document (color dropout)
You can filter out a color channel (red, green, or blue) or up to three individual colors. For specific
colors, the sensitivity setting controls how closely a scanned color must approximate the specified
color.
Removing colors from the scan might reduce the scan file size and improve optical character
recognition (OCR) results.
To select colors to eliminate from a scan in an HP Smart Document Scan Software profile, follow
these steps:
1. Open the HP Smart Document Scan Software.
2. Select a scan profile, and then click Edit profile.
3. On the Scan tab of the Profile Settings dialog box, click Color Dropout.
4. Under Color dropout, specify the color dropout settings.
Only the color dropout options available for your scanner are selectable.
For information about the color dropout settings, see the online help for the scanning software that
you are using.
NOTE: The color channel filter only applies to grayscale scans and to black and white scans.
Specific color filters apply to all color modes.
NOTE: Use the ISIS or TWAIN user interface to filter out color when scanning from third-party
scanning software.
Automatically crop scanned image
To automatically crop a scan, follow these steps:
1. Open the HP Smart Document Scan Software.
2. Select a scan profile, and then click Edit profile.
3. Select your crop options.
To automatically crop to the content of the document, click the Image Processing tab of
●

Scanned image is fuzzy
Verify that the document original is not fuzzy.
Scanner operation problems 45
Use the Kofax Virtual ReScan Software which shipped with your scanner to process the scanned
data. Such software cleans up the image and compresses the data.
Check for any obstructions in the scanner paper path and make sure the paper width guides are
positioned appropriately. Try another scan.
Clean the scanning strip to the left of the scanner glass.
Check the JPEG compression setting. If scanner compression is high, scanned data might be lost by
the compression.
Scanned pages are out of order at the scan destination
Verify that the page order of the original document is correct before placing it face-up into the
document feeder.
Make sure that there are no staples, paper clips, or any other attached material (such as adhesive
notes) that may cause the pages to feed incorrectly.
Verify that pages are not stuck together.
Optimize scanning and task speeds
Several settings influence the total time for a scanning job. When you want to optimize scanning
performance, consider the following information.
To optimize performance, make sure your computer meets the recommended system
●
requirements. To view minimum and recommended system requirements, see
select your country/region, search on your scanner model, and then search on datasheet.
In the scanning software, choose the layout setting that matches the orientation of the originals
●
in the document feeder.
To optimize data transfer from the scanner to the scanning software on the computer, enable
●
scanner hardware (JPEG) compression. Typically, the use of scanner compression reduces the
time to complete all color scans and grayscale scans with resolution above 300 dpi. Scanner
compression affects the rate of data transfer only and can be used with all output formats.
NOTE: You cannot use scanner compression with black and white originals.
Saving a scanned image to a searchable format (for example, searchable PDF) takes more time
●
than saving to an image format because the scanned image is analyzed using Optical Character
Recognition (OCR). Turn on OCR only when you need a searchable document.
NOTE: For the best OCR results, scanner compression should be set to the minimum
compression level or disabled.
Scanning at a higher resolution than necessary increases scanning time and creates a larger file
●
with no additional benefit. If you are scanning at a high resolution, set the resolution to a lower
level to increase scanning speed.
The scan is completely black or completely white
www.hp.com,
The item might not be placed correctly in the document feeder. Make sure that the item you are trying
to scan is placed face up.
46 Chapter 5 Troubleshooting
Scanned images are not straight
Verify that the document feeder guides are centered on the scanner and set to an appropriate width
for the original being scanned. Make sure the paper guides touch the edges of the original.
Vertical white stripes appear on the printed page
The destination printer might be out of toner or ink. Scan a different original to the same printer to see
if the issue lies with the printer.
If the second scan has the same problem, try scanning to a different printer.
Vertical colored stripes appear on the printed page
Dust can build up on the scanning strip and cause artifacts in scanned images. Clean the scanning
strip (which is to the left of the scanner glass) with a soft, lint-free cloth that has been sprayed with a
mild glass cleaner.
Scan files are too large
If the saved scan files are very large, 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 Virtual ReScan Software which shipped with your scanner to process the
●
scanned data. Such software cleans up the image and compresses the data, which can result in
a smaller file.

hatch are closed.
If the pages look skewed as they feed into the scanner paper path, check the resulting scanned
●
images in the software to ensure that they are not skewed.
The pages might not be placed correctly. Straighten the pages and adjust the paper guides to
●
center the stack.
The paper guides must be touching the sides of the paper stack to work properly. Please ensure
●
that the paper stack is straight and the guides are against the paper stack.
The document feeder or output tray might contain more than the maximum number of pages.
●
Load fewer pages in the document feeder, and remove pages from the output tray.
Clean the scanner paper path to help reduce misfeeds. If misfeeds still occur, clean the rollers. If
●
misfeeds still occur, replace the rollers.
Scanning fragile originals
To safely scan fragile originals (photographs or documents on wrinkled or very lightweight paper)
place originals on the scanner glass. Do not use the automatic document feeder (ADF).
Paper does not feed from the scanner
Reload the pages into the document feeder, ensuring that they make contact with the rollers.
The automatic document feeder (ADF) hatch might not be securely latched. Open the ADF hatch and
then close it by pressing firmly.
A problem with the scanner hardware might exist. Follow this procedure to test the scanner:
1. Ensure that the power supply is securely connected between the scanner and a live electrical
outlet or surge protector. Check that the green LED on the power supply case is on to verify that
the power supply is functional.
2. If the power supply is connected to a surge protector, ensure that the surge protector is plugged
into an outlet and turned on.

3. Disconnect the power supply from the scanner and turn off the computer. After 30 seconds,
reconnect the power supply to the scanner and then turn on the computer, in that order.
4. Try to rescan.
Originals are curling up in the scanner output tray.
Under dry conditions, lightweight originals such as those printed on carbonless copy paper may curl
in the output tray. To minimize curl, flatten curled edges on the originals before placing them in the
document feeder. If you cannot flatten curled edges, make sure the curled edges are facing down
when you place the originals in the document feeder.
The bottom of the scanned image is cut off
By default, the scanning software can scan media that is up to 356 mm (14 in) long. For longer
pages, the end of the document is not included in the scanned image.
Verify that you have specified an appropriate page size in the scanning software.
The scanned images have streaks or scratches
After each step, try another scan to see if the streaks or scratches are still apparent. If so, then try the
next step. For information on cleaning the scanner, see the Care and maintenance section.
Check that the originals are clean and unwrinkled.
