Solve paper-feed problems
Media is not supported for the printer or tray
Use only media that is supported for the printer and the tray being used. For more
information, see 
Media specifications.
Media is not picked up from a tray
• Make sure media is loaded in the tray. For more information, see 
Load media. Fan
the media before loading.
• Make sure the paper guides are set to the correct markings in the tray for the media
size you are loading. Also make sure the guides are snug, but not tight, against the
stack.
• Make sure media in the tray is not curled. Uncurl paper by bending it in the opposite
direction of the curl.
• When using thin special media, make sure that the tray is completely loaded. If you
are using special media that is only available in small quantities, try placing the special
media on top of other paper of the same size to help fill the tray. (Some media is
picked up more easily if the tray is full.)
• If you are using thick special media (such as brochure paper), load media so that the
tray is between 1/4 and 3/4 full. If necessary, place the media on top of other paper
of the same size so that the stack height is within this range.

• Make sure the output tray extender is fully extended; otherwise, printed pages may
fall off the printer.
NOTE:When printing documents larger than A3/11 x 17 inches, extend the
output tray extender all the way and tilt the paper stopper.
• Remove excess media from the output tray. There is a limit to the number of sheets
the tray can hold.
Pages are skewing
• Make sure the media loaded in the trays is aligned to the paper guides. If needed,
pull out the trays from the printer and reload the media correctly, making sure that the
paper guides are correctly aligned.
• Load media into the printer only when it is not printing.

							Scan takes too long
•Check the settings
◦If you set the resolution too high, the scan job takes longer and results in larger
files. To obtain good results when scanning or copying, do not use a resolution
that is higher than needed. You can lower the resolution to scan more quickly.
◦If you acquire an image through TWAIN, you can change the settings so that the
original scans in black and white. See the onscreen Help for the TWAIN program
for information.
•Check the status of the printer
If you sent a print or copy job before you tried to scan, the scan starts if the scanner
is not busy. However, the printing and scanning processes share memory, which
means that the scan might be slower.
Part of the document did not scan or text is missing
•Check the original
◦Make sure that you loaded the original correctly. For more information, see 
Load
an original on the scanner glass.
◦If you are copying a borderless original, load the original on the scanner glass,
not the ADF. For more information, see 
Load an original on the scanner glass.
◦Colored backgrounds can cause images in the foreground to blend into the
background. Try adjusting the settings before you scan the original, or try
enhancing the image after you scan the original.
•Check the settings
◦Make sure that the input media size is large enough for the original that you are
scanning.
◦If you are using the HP software provided with the printer, the default settings in
the HP software might be set to automatically perform a specific task other than
the one that you are attempting. See the onscreen Help for the HP software for
instructions about changing the properties.
◦If you have selected a picture scanning option, the HP software automatically
crops the image. However, if you want to scan the entire page, complete the
following steps:
Windows: From the HP software, click Scanner Actions, click Scan
Properties, and then select Scan the entire glass.
Mac OS X: From the HP software, click Scan, select the Pictures scan profile,
click Profile Settings, and then clear the Crop check box.

							Text cannot be edited
•Check the settings
◦When you scan the original, make sure that you select a document type that
creates editable text. If text is classified as a graphic, it is not converted to text.
◦If you are using a separate OCR (optical character recognition) program, the OCR
program might be linked to a word-processing program that does not perform
OCR tasks. For more information, see the documentation provided with the OCR
program.
◦Make sure you have selected an OCR language that corresponds to the language
used for the document you are scanning. For more information, see the
documentation provided with the OCR program.
•Check the originals
◦When scanning documents as editable text from the ADF, the original must be
loaded into the ADF with the top forward and face up. When scanning from the
scanner glass, the original must be loaded with the top facing the right edge of
the scanner glass. Also, make sure the document is not skewed. For more
information, see 
Load an original on the scanner glass or Load an original in the
automatic document feeder (ADF).
◦The software might not recognize text that is tightly spaced. For example, if the
text that the software converts has missing or combined characters, rn might
appear as m.
◦The accuracy of the software depends on the image quality, text size, and
structure of the original and the quality of the scan itself. Make sure that your
original has good image quality.
◦Colored backgrounds can cause images in the foreground to blend too much.
Error messages appear
Unable to activate TWAIN source or An error occurred while acquiring the
image
◦If you are acquiring an image from another device, such as a digital camera or another
scanner, make sure that the other device is TWAIN-compliant. Devices that are not
TWAIN-compliant do not work with the HP software.
◦Make sure that you have connected the USB cable to the correct port on the back of
your computer.
◦Verify that the correct TWAIN source is selected. In the software, check the TWAIN
source by selecting Select Scanner on the File menu.
Scanned image quality is poor 
The original is a second-generation photo or picture
Reprinted photographs, such as those in newspapers or magazines, are printed by using
tiny dots of ink that make an interpretation of the original photograph, which degrades the
quality. Often, the ink dots form unwanted patterns that can be detected when the image

							is scanned or printed or when the image appears on a screen. If the following suggestions
do not solve the problem, you might need to use a better-quality version of the original.
◦To eliminate the patterns, try reducing the size of the image after scanning.
◦Print the scanned image to see if the quality is better.
◦Make sure that the resolution and color settings are correct for the type of scan job.
Text or images on the back of a two-sided original appear in the scan
Two-sided originals can bleed text or images from the back side to the scan if the
originals are printed on media that is too thin or too transparent.
The scanned image is skewed (crooked)
The original might have been placed incorrectly. Be sure to use the media guides when
you place the original on the scanner glass. For more information, see 
Load an original
on the scanner glass.
The image quality is better when printed
The image that appears on the screen is not always an accurate representation of the
quality of the scan.
◦Try adjusting your computer monitor settings to use more colors (or levels of gray).
On Windows computers, you typically make this adjustment by opening Display on
the Windows control panel.
◦Try adjusting the resolution and color settings.
The scanned image shows blots, lines, vertical white stripes, or other defects
◦If the scanner glass is dirty, the image produced does not have optimum clarity. See
Maintain the printer for cleaning instructions.
◦The defects might be on the original and not a result of the scanning process.
Graphics look different from the original
The graphics settings might not be suitable for the type of scan job that you are
performing. Try changing the graphics settings.
Take steps to improve the scan quality
◦Use high-quality originals.
◦Place the media correctly. If the media is placed incorrectly on the scanner glass, it
might skew, which causes unclear images. For more information, see 
Load an original
on the scanner glass.
◦Adjust the software settings according to how you plan to use the scanned page.
◦Use or make a carrier sheet to protect your originals.
◦Clean the scanner glass. See 
Clean the scanner glass for more information.
