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 speci fications.
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.
Media is not coming out correctly
• Make sure the output tray extender is fully extended; otherwise, printed pages may fall off the printer.

							• Remove excess media from the output tray. There is a limit to the number of sheetsthe 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 aligned correctly.
• Load media into the printer only when it is not printing.
• Remove and replace the duplexer.  Push the button on either side of the duplexer, and then remove the unit.
 Reinsert the duplexer into the printer.
Multiple pages are  being picked up
• 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 the tray is not overloaded with paper.
• When using thin special media, make sure that the tray is completely loaded. If you are using special media that is only avail able 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.
• Use HP media for optimum  performance and efficiency.

The printer might be coming out of Sleep mode after a period of inactivity, which
delays processing a short while. Wait until the printer displays the Home screen.
• Check the HP software
Make sure the HP software provided with the printer is installed correctly.
Scan takes too long
•Check the settings
 If you set the resolution  too high, the scan job takes lo nger and results in larger
files. To obtain good results, 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 pro cesses share memory, which
means that the scan might be slower.

•Check the original
 Make sure that you load ed the original correctly. For more information, see
Load an original on the scanner glass or Load an original in the automatic
document feeder (ADF).
 If you scanned the document from the  ADF, try scanning the document directly
from the scanner glass. For  more information, see 
Load an original on the

							 If you are using a separate OCR (optical character recognition) program, theOCR 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, the original must be loaded into the
scan tray with the top forward and face down. Also, make sure the document is
not skewed. For more information, see 
Load an original on the scanner glass.
 The software might not recognize  text that is tightly spaced. For example, if the
text that the software convert s has missing or combined characte rs, "rn" might
appear as "m."
 The accuracy of the software depend s 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 wo rk with the HP software provided with
the printer.
 If you are using a USB connection, make sure that you have connected the USB Device Cable to th e correct port on the back of your computer.
 Verify that the correct TWAIN source is selected. In the HP software, check the TWAIN source by selecting  Select Scanner on the File menu.
• Reload document and then restart job
Touch  OK on the printer control panel, and then reload the remaining documents in
the ADF. For more information see 
Load an original in the automatic document
feeder (ADF).
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 set tings are correct for the type of scan job.
 For best results, use the scanner glass for scanning rather than the ADF.
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 t hat is too thin or too transparent.
The scanned image is skewed (crooked)
The original might have been loaded incorrectly. Be sure to use the media guides when
you load the originals into the ADF. For more information, see 
Load an original in the
automatic document feeder (ADF).
For best results, use the scanner glass for scanning rather than the ADF.
The image quality is better when printed
