•Check the original
Make sure that the original is placed on the scanner glass correctly. For more
information, see 
Load an original on the scanner glass.
•Check the device
The device might be coming out of PowerSave mode after a period of inactivity, which
delays processing a short while. Wait until the device reaches the READY state.
•Check the software
Make sure the software is properly installed.
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 device
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, 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 Solution Center software, click Scan Picture, click
Advanced Picture Settings, and then select Scan the entire glass.
Mac OS X: From the HP Scan software, click Scan, select the Picturesscan
profile, click Profile Settings, and then clear the Cropcheck box.
Text cannot be edited
•Check the settings
◦Make sure the HP software (or any additional OCR software) is properly installed.
◦When you scan the original, make sure that you select a document type or save
the scan in a format that creates editable, searchable text. If text is classified as
a graphic, it is not converted to text.
◦Your OCR program might be linked to a word-processing program that does not
perform OCR tasks. See the product software Help for more information about
linking programs.
•Check the originals
◦Make sure that you placed the original correctly on the scanner glass. For more
information, see 
Load an original on the scanner glass.
◦The OCR program might not recognize text that is tightly spaced. For example, if
the text that the OCR program converts has missing or combined characters, rn
might appear as m.
◦The accuracy of the OCR program 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. Try
adjusting the settings before you scan the original, or try enhancing the image
after you scan the original. If you are performing an OCR operation on an original,
any colored text on the original does not scan well, if at all.

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 device 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 device 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

more information. If cleaning does not correct the problem, the scanner glass or
lid backing might need to be replaced.
◦The defects might be on the original and not a result of the scanning process.
•Unclear text
Try adjusting the settings. Make sure that the resolution and color settings are correct.
•Size is reduced
The HP software settings might be set to reduce the scanned image. See the product
software Help for more information about changing the settings.

Solution:You are using the wrong type of phone cord. Make sure you are using
the phone cord that came with the device to connect the device to your phone line. If
the phone cord that came with the device is not long enough, you can use a coupler
to extend the length. You can purchase a coupler at an electronics store that carries
phone accessories. You will also need another phone cord, which can be a standard
phone cord that you might already have in your home or office.
Solution:Other equipment that uses the same phone line as the device might be
in use. Make sure extension phones (phones on the same phone line, but not
connected to the device) or other equipment are not in use or off the hook. For
example, you cannot use the device for faxing if an extension phone is off the hook,
or if you are using a computer dial-up modem to send e-mail or access the Internet.
The device is having problems sending and receiving faxes
Solution:Make sure the device is turned on. Look at the display on the device. If
the display is blank and the Power light is not lit, the device is turned off. Make sure
the power cord is firmly connected to the device and plugged into a power outlet.
Press the Power button to turn on the device.
After turning on the device, HP recommends you wait five minutes before sending or
receiving a fax. The device cannot send or receive faxes while it is initializing after
