paper. If you are printing on other types of paper, such as labels or transparencies,
check that you have selected the correct paper type in the HP Photosmart software.
For more information, see:
•“
Set the paper type for printing” on page 31
•“
Load full-size paper” on page 21
Cause: The copy or print quality setting on the HP All-in-One is set too low.
Solution: Check the quality setting. Use a higher quality setting to increase the
amount of ink used for printing.

The text edges are jagged
Cause: The font is a custom size.
Solution: Some software applications offer custom fonts that have jagged edges
when enlarged or printed. Also, if you want to print bitmapped text, it might have
jagged edges when enlarged or printed.
Use OpenType or TrueType fonts to ensure  that the HP All-in-One is able to print
smooth fonts. When selecting a font, look for the TrueType or OpenType icon.
The printout has a horizontal band of distortion near the bottom of the page
Cause: Your image has light blue, gray, or brown hues that print near the bottom
of the page.
Solution: Load high-quality paper in the input tray and print the image with a high
print quality sett ing, such as Best, Maximum dpi , or High Resolution . Always make
sure the paper you are printing on is flat. For best results when printing images,
use HP Premium Plus Photo Paper.
If the problem persists, use the software you installed with the HP All-in-One or
another software application to rotate your image 180 degrees so that the light blue,
gray, or brown hues in your image do not print at the bottom of the page. Print the
image using six-ink printing. To do so, install the photo print cartridge in place of the
black print cartridge. With the photo print cartridge and the tri-color print cartridge
installed, you have a six-ink system, which provides enhanced quality photos.

Colors run into each other on the printoutCause: The print or copy quality setting is set too high for the type of paper loaded
in the HP All-in-One.
Solution: Check the quality setting. Use a lower quality setting to decrease the
amount of ink used for printing or copying.
For more information, see:
•“
Change the print speed or quality” on page 32
•“
Change copy speed or quality” on page 55
Cause: The paper type is not suitable for the HP All-in-One.
Solution: Use HP Premium Papers or any other paper type that is appropriate for
the HP All-in-One.
For more information, see:
“
Information on paper” on page 81
Cause: You are printing on the wrong side of the paper.
Solution: Load the paper with the print side down. For example, if you are loading
glossy photo paper, load the paper  with the glossy side down.
For more information, see:
“
Load full-size paper” on page 21
Cause: You are using non-HP ink.
Solution: HP recommends that you use genuine HP print cartridges. Genuine HP
print cartridges are designed and tested with HP printers to help you easily produce
great results, time after time.
NOTE: HP cannot guarantee the quality or reliability of non-HP ink. Printer
service or repairs required as a result of printer failure or damage attributable to
the use of non-HP ink will not be covered under warranty.
Cause: The print cartridges need to be cleaned.
Solution: Print a self-test report to determine if there is a problem with the print
cartridges. If the self-test report shows a problem, clean the print cartridges. If the
problem persists, you might need to replace the print cartridges.

Cause: The copy or print quality type setting on the HP All-in-One is set too low.
Solution: Check the quality setting. Use a higher quality setting to increase the
amount of ink used for printing.
For more information, see:

installation.
Solution: Allow half an hour for the  print cartridge to recover.
Cause:The print cartridges need to be cleaned or might be out of ink.
Solution: Check the estimated ink levels remain ing in the print cartridges. If the
print cartridges are low or out of ink, you might need to replace the print cartridges.
If there is ink remaining in the print cartridges, but you are still noticing a problem,
print a self-test report to determine if there is a problem with the print cartridges. If the
self-test report shows a problem, clean the print cartridges. If the problem persists,
you might need to replace the print cartridges.

on page 83 .
Cause:There might be fiber or dust built up around the ink nozzle area on the print
cartridges.
Solution: Check the print cartridges. If it looks as though there are fibers or dust
around the ink nozzles, clean the ink nozzle area of the print cartridge.
For more information, see:
“
Clean the area around the ink nozzles” on page 74
Printouts or copies are faded or have dull colors
Cause: The print cartridges need to be cleaned or might be out of ink.

Cause:The print quality setting on the HP All-in-One is set too low.
Solution: Check the quality setting. Use a higher quality setting to increase the
amount of ink used for printing.
Cause: The paper type is not suitable for the HP All-in-One.
Solution: If the paper you are using is too fibrous, the ink applied by the HP All-in-
One might not fully cover the surface of the paper. Use HP Premium Papers or any
other paper type that is appropriate for the HP All-in-One.
For more information, see:
“
Choose papers for printing and copying” on page 18
Cause: The paper type setting is incorrect.
Solution: Change the paper type setting to match the type of paper loaded in the
input tray. The HP All-in-One automatically detects the paper type for plain and photo
paper. If you are printing on other types of  paper, such as labels or transparencies,
check that you have selected the correct paper type in the HP Photosmart Software.
For more information, see:
“
Set the paper type for printing” on page 31
Cause: Copying a poor-quality picture, such as a newspaper photo, causes bands,
checks, or stripes to appear on your copy. These are called moiré patterns.
Solution: To reduce moiré patterns, try placing one or more clear plastic sheet
protectors directly on the glass, and then place the original print side down on top of
the sheet protectors.
Cause: Debris might be stuck on the glass or on the back of the document lid; this
causes poor copy quality and slows down processing.
Solution:

Cause:More than one type of paper is loaded in the input tray.
Solution: Load only one type of paper at a time.
Paper is not picked up  from the input tray
Cause: There is not enough paper in the input tray.
Solution: If the HP All-in-One is out of paper or there are only a few sheets
remaining, load more paper in the input tray. If there is paper in the input tray, remove
the paper, tap the stack of paper against a flat surface, and reload the paper into the
input tray. To continue your print job, press  Start Copy Black on the control panel of
the HP All-in-One.

carriage (including any packing materials), and then turn the HP All-in-One on again.
Cause: The computer is not communicating with the HP All-in-One.
Solution: If the HP All-in-One is not properly connected to the computer,
communication errors can occur. Make sure the USB cable is connected to the HP All-
in-One and the computer as shown below.
If the connections are secure, and nothing has printed several minutes after you sent
a print job to the HP All-in-One, check the status of the HP All-in-One. In the
HP Photosmart Software, click  Status.

Cause: The HP All-in-One is turned off.
Solution: Look at the On button located on the top of the HP All-in-One. If it is not
lit, the HP All-in-One is turned off. Make sure the power cord is firmly connected to
the HP All-in-One and plugged into a power outlet. Press the  On button to turn on the
HP All-in-One.
Cause: The HP All-in-One experienced an error.
Solution: Turn the HP All-in-One off, and then unplug the power cord. Plug the

Solution:The printer driver status might have changed to either  offline or stop
printing .
To check the printer driver status
1. In the HP Solution Center, click the device tab.
2. Click  Settings .
3. Click  Status .
If the status is  offline or stop printing , change the status to  ready.
Cause: A deleted print job is still in the queue.
Solution: A print job might remain in the queue after it has been cancelled. The
cancelled print job jams the queue and prevents the next print job from printing.
From your computer, open the printer folder and see if the cancelled job remains in
the print queue. Try to delete the job from  the queue. If the print job remains in the
queue, try one or both of the following:
• Disconnect the USB cable from the HP All-in-One, restart the computer, and then
reconnect the USB cable to the HP All-in-One.
• Shut down the HP All-in-One, restart the computer, and then restart the HP All-
in-One.
