							Solution:Check the estimated ink levels remaining 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.
For more information on print cartridges, see 
Print cartridge troubleshooting.

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:
To clean the glass
1.Turn off the HP All-in-One, and raise the lid.
2.Clean the glass with a soft cloth or sponge slightly moistened with a nonabrasive
glass cleaner.
CAUTION:Do not use abrasives, acetone, benzene, or carbon tetrachloride
on the glass, since they can damage it. Do not place or spray liquid directly
on the glass. The liquid might seep under the glass and damage the device.
3.Dry the glass with a dry, soft, lint-free cloth to prevent spotting.
4.Turn on the HP All-in-One.
To clean the lid backing
1.Turn off the HP All-in-One, unplug the power cord, and raise the lid.
NOTE:Depending how long the HP All-in-One is unplugged, the date and
time might be erased. You might need to reset the date and time later, when
you plug the power cord back in.
2.Clean the white document backing with a soft cloth or sponge slightly moistened
with a mild soap and warm water.
Wash the backing gently to loosen debris. Do not scrub the backing.
3.Dry the backing with a dry, soft, lint-free cloth.
CAUTION:Do not use paper-based wipes, as these might scratch the
backing.
4.If further cleaning is needed, repeat the previous steps using isopropyl (rubbing)
alcohol, and wipe the backing thoroughly with a damp cloth to remove any residual
alcohol.
CAUTION:Be careful not to spill alcohol on the glass or exterior of the HP All-
in-One, as this might damage the device.
Printouts seem blurry or fuzzy
Cause:The fax sender is using a low resolution or the original was poor quality.
Solution:Ask the sender to increase the resolution and to verify the quality of the
original.
Cause:The paper loaded in the input tray 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.

							Solution:Load paper with the print side down. For example, if you are loading
glossy photo paper, load the paper with the glossy side down.
Printouts have vertical streaks
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 on choosing paper, see 
Understand specifications for supported
media.
Cause:The glass or automatic document feeder of the sending fax machine is dirty.
Solution:If you have vertical lines or streaks on the fax, the senders fax machine
might have dirt or dust on the glass or automatic document feeder. Check with the
sender to see if the glass or automatic document feeder is clean.
Printouts are slanted or skewed
Cause:The paper is not feeding properly or is loaded incorrectly.
Solution:Make sure the paper is loaded correctly.
To load full-size paper
1.Remove the output tray.
Print quality troubleshooting 143
 
						

							2.Slide the paper-width guide to its outermost position.
3.Tap a stack of paper on a flat surface to align the edges, and then check the paper
for the following:
• Make sure it is free of rips, dust, wrinkles, and curled or bent edges.
• Make sure all the paper in the stack is the same size and type.
4.Insert the stack of paper into the input tray with the short edge forward and the
print side down. Slide the stack of paper forward until it stops.
CAUTION:Make sure that the HP All-in-One is idle and silent when you load
paper into the input tray. If the HP All-in-One is servicing the print cartridges
or otherwise engaged in a task, the paper stop inside the device might not be
in place. You could push the paper too far forward, causing the HP All-in-One
to eject blank pages.
TIP:If you are using letterhead, insert the top of the page first with the print
side down. For more help on loading full-size paper and letterhead, refer to
the diagram engraved in the base of the input tray.

							5.Slide the paper-width guide inward until it stops at the edge of the paper.
Do not overload the input tray; make sure the stack of paper fits within the input
tray and is no higher than the top of the paper-width guide.
6.Replace the output tray.
7.Flip the tray extender up toward you.
NOTE:When you use legal-size paper, leave the tray extender closed.
Cause:The original might have been loaded incorrectly into the sending fax
machine.
Solution:Ask the sender to check that the fax was sent correctly.
Cause:More than one type of paper is loaded in the input tray.
Print quality troubleshooting 145
 
						

							Solution:Load only one type of paper at a time. When you are printing faxes, make
sure letter, A4, or legal paper is loaded in the input tray.
The print quality of the fax I received is poor
Cause:The phone line connection is noisy.
Solution:If the failure was due to noise on the phone line, contact the sender to
have them resend the fax. The quality might be better when you try again. You can
check the sound quality of the phone line by plugging a phone into the telephone wall
jack and listening for static or other noise. If the problem persists, turn Error
Correction Mode (ECM) off and contact your telephone company.
To change the ECM setting from the control panel
1.Press Setup.
2.Press 5, and then press 6.
This selects Advanced Fax Setup and then selects Error Correction Mode.
3.Press 
 to select On or Off.
4.Press OK.
Cause:The sending fax machine is having problems.
Solution:Ask the sender to check the sending fax machine for any problems. Also
check to see if faxes from other senders have the same quality problems.
Cause:The glass or automatic document feeder of the sending fax machine is dirty.
Solution:If you have vertical lines or streaks on the fax, the senders fax machine
might have dirt or dust on the glass or automatic document feeder. Check with the
sender to see if the glass or automatic document feeder is clean.
Cause:The print cartridges need to be cleaned or might be out of ink.
Solution:Check the estimated ink levels remaining 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.

							self-test report shows a problem, clean the print cartridges. If the problem persists,
you might need to replace the print cartridges.
For more information on print cartridges, see 
Print cartridge troubleshooting.
Cause:The sender incorrectly loaded the originals in the sending fax machine.
Solution:Check with the sender to see if they correctly loaded the originals in the
sending fax machine or accidentally sent a blank page.
Cause:The HP All-in-One picked up two sheets of paper while printing the fax.
Solution:If the HP All-in-One has only a few sheets remaining, load more paper in
the input tray. If there is plenty of 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.
Cause:The paper loaded in the input tray is not suitable for your fax.
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.
Ink is overspraying the paper when I copy or print a photo
Cause:A small amount (a few millimeters) of overspray is common when making
a copy of a photo. If there are more than a few millimeters of overspray, it might mean
the HP All-in-One thinks the paper loaded is wider than it actually is.
TIP:One way to tell if ink is overspraying the paper is to check the back side of
pages you print after running a copy or print job. If the back side of the page has
ink streaks, the HP All-in-One might have over sprayed your previous copy or print
job.
Solution:Check the paper size setting. Set the paper size to match the paper
loaded in the input tray.
To set the paper size from the control panel
1.In the Copy area, press Menu repeatedly until Copy Paper Size appears.
2.Press 
 until the appropriate paper size appears.
3.Press Start Copy Black or Start Copy Color.
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 OK on the control panel of the HP All-in-
One.
