							Clean the area around the ink nozzles
If the HP All-in-One is used in a dusty environment, a small amount of debris might
accumulate inside the device. This debris can include dust, hair, carpet, or clothing fibers.
When debris gets on the print cartridges, it can cause ink streaks and smudges on printed
pages. Ink streaking can be corrected by cleaning around the ink nozzles as described
here.
NOTE:Clean the area around the ink nozzles only if you continue to see streaks
and smudges on your printed pages after you have already cleaned the print
cartridges by using the control panel or the software you installed with the HP All-in-
One.
Make sure you have the following materials available:
•Dry foam rubber swabs, lint-free cloth, or any soft material that will not come apart or
leave fibers.
TIP:Coffee filters are lint-free and work well for cleaning print cartridges.
•Distilled, filtered, or bottled water (tap water might contain contaminants that can
damage the print cartridges).
CAUTION:Do not touch the copper-colored contacts or ink nozzles. Touching
these parts can result in clogs, ink failure, and bad electrical connections.
To clean the area around the ink nozzles
1.Turn on the HP All-in-One and open the print cartridge door.
The print carriage moves to the far right side of the HP All-in-One.
2.Wait until the print carriage is idle and silent, and then unplug the power cord from
the back of the HP All-in-One.
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.
3.Lightly press down on the print cartridge to release it, and then pull it toward you out
of the slot.
NOTE:Do not remove both print cartridges at the same time. Remove and clean
each print cartridge one at a time. Do not leave a print cartridge outside the HP All-

The HP All-in-One will not turn on
Cause:The HP All-in-One is not properly connected to a power supply.
Troubleshooting 123
 
						

							Solution:
•Make sure the power cord is firmly connected to both the HP All-in-One and the
power adapter. Plug the power cord into a grounded power outlet, surge protector,
or power strip.
1Power connection
2Power cord and adapter
3Grounded power outlet
•If you are using a power strip, make sure the power strip is on. Or, try plugging
the HP All-in-One directly into a grounded power outlet.
•Test the power outlet to make sure it is working. Plug in an appliance that you
know works, and see if the appliance has power. If not, then there might be a
problem with the power outlet.
•If you plugged the HP All-in-One into a switched outlet, make sure the switch is
on. If it is switched to on but still does not work, then there might be a problem
with the power outlet.
Cause:You pressed the Power button too quickly.
Solution:The HP All-in-One might not respond if you press the Power button too
quickly. Press the Power button once. It might take a few minutes for the HP All-in-
One to turn on. If you press the Power button again during this time, you might turn
the device off.
CAUTION:If the HP All-in-One still does not turn on, it might have a mechanical
failure. Unplug the HP All-in-One from the power outlet and contact HP. Go to:
www.hp.com/support. If prompted, choose your country/region, and then click
Contact HP for information on calling for technical support.

							Communication problems over a USB connection
If the HP All-in-One and computer are not communicating with each other, try the
following:
•Look at the display on the HP All-in-One. If the display is blank and the Power button
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 Power button to turn
on the HP All-in-One.
•Check the USB cable. If you are using an older cable, it might not be working properly.
Try connecting it to another product to see if the USB cable works. If you experience
problems, the USB cable might need to be replaced. Also verify that the cable does
not exceed 3 meters (9.8 feet) in length.
•Make sure your computer USB ports are enabled. Check the documentation that
came with your operating system for more information.
•Check the connection from the HP All-in-One to your computer. Verify that the USB
cable is securely plugged into the USB port on the back of the HP All-in-One. Make
sure the other end of the USB cable is plugged into a USB port on your computer.
After the cable is connected properly, turn the HP All-in-One off and then on again.
•If you are connecting the HP All-in-One through a USB hub, make sure the hub is
turned on. If the hub is on, try connecting directly to your computer.
•Check other printers or scanners. You might need to disconnect older products from
your computer.
•Try connecting the USB cable to another USB port on your computer. After you check
the connections, try restarting your computer. Turn the HP All-in-One off and then on
again.
For more information on setting up the HP All-in-One and connecting it to your computer,
see the Setup Poster that came with the HP All-in-One.
Troubleshooting tips 125
 
						

							Information on print cartridges
For best results, use HP print cartridges. The following tips help maintain HP print
cartridges and ensure consistent print quality.
•Keep all print cartridges in the original sealed packages until they are needed.
•Store print cartridges at room temperature (15.6°-26.6° C or 60°-78° F).
•Do not reattach the protective tape once it has been removed from the print cartridge.
Reattaching the plastic tape might damage the print cartridge. Place the print cartridge
in the HP All-in-One immediately after removing the plastic tape. If this is not possible,
store it in a print cartridge protector or airtight plastic container.
•HP recommends that you do not remove the print cartridges from the HP All-in-One
until you have replacement print cartridges available to install.
•Turn off the HP All-in-One from the control panel. Do not turn off the device by turning
off a power strip or unplugging the power cord from the HP All-in-One. If you
improperly turn off the HP All-in-One, the print carriage does not return to the correct
position and the print cartridges can dry out.
•Do not open the print cartridge door unless necessary. This exposes the print
cartridges to air, which reduces the life of the print cartridges.
NOTE:If you leave the print cartridge door open for a long period of time, the
HP All-in-One will recap the print cartridges to protect them from exposure to air.
•Clean the print cartridges when you notice a significant decrease in print quality.
TIP:You might notice a decrease in print quality if the print cartridges have not
been used for a long time.
•Do not clean the print cartridges unnecessarily. This wastes ink and shortens the life
of the cartridges.
For more information on print cartridges, see 
Print cartridge troubleshooting.
Information on paper
The HP All-in-One is designed to work well with most paper types. Test a variety of paper
types before buying a large quantity. Find a paper type that works well and is easy to
purchase. HP Premium papers are designed for the best quality results. In addition, follow
these tips:
•Do not use paper that is too thin, that has a slick texture, or that stretches easily. It
can feed incorrectly through the paper path, causing paper jams.
•Store photo media in its original packaging inside a resealable plastic bag on a flat
surface in a cool, dry place. When you are ready to print, remove only the paper you
plan to use immediately. When you have finished printing, return any unused photo
paper to the plastic bag.
•Do not leave unused photo paper in the input tray. The paper might start to curl, which
might reduce the quality of your printouts. Curled paper can also cause paper jams.
•Always hold photo paper by the edges. Fingerprints on photo paper can reduce print
quality.
•Do not use paper that is heavily textured. It can cause graphics or text to print
improperly.
Chapter 12
126 Troubleshooting
 
						

							•Do not combine different paper types and paper sizes in the input tray; the entire stack
of paper in the input tray must be the same size and type.
•Store printed photos under glass or in a storage book to prevent bleeding over time
from high humidity. Use HP Premium Plus photo paper for maximum performance.
Tips for using the automatic document feeder
Follow these simple suggestions to avoid common problems when using the automatic
document feeder.
•Remove any staples or clips from the original document.
•Make sure the paper is not too thick or too thin for the HP All-in-One to process.
•Do not overload the document feeder tray. The document feeder tray can hold up to
20 sheets of letter or A4 paper, or up to 15 sheets of legal paper.
•Do not use spiral or frayed paper. If you must use paper that has been removed from
a spiral binder, trim the edges.
•Do not load photos in the automatic document feeder. The automatic document
feeder can damage photos. Always place photos on the glass to scan or copy.
•Make sure the paper-width guides in the document feeder tray fit snugly against the
paper without bending the paper.
•Load your originals print side up into the document feeder tray.
Clear paper jams
If the paper was loaded in the input tray, you might need to clear the paper jam from the
rear door.
Paper can also jam in the automatic document feeder. Several common actions can
cause paper to jam the automatic document feeder:
•Placing too much paper in the document feeder tray. For information on the maximum
number of sheets allowed in the automatic document feeder, see 
Technical
information.
•Using paper that is too thick or too thin for the HP All-in-One.
•Trying to add paper to the document feeder tray while the HP All-in-One is feeding
pages.
To clear a paper jam from the rear door
1.Press in the tab on the left side of the rear door to release the door. Remove the door
by pulling it away from the HP All-in-One.
CAUTION:Trying to clear a paper jam from the front of the HP All-in-One can
damage the print mechanism. Always access and clear paper jams through the
rear door.

							2.Gently pull the paper out of the rollers.
CAUTION:If the paper tears when you are removing it from the rollers, check
the rollers and wheels for torn pieces of paper that might be remaining inside the
device. If you do not remove all the pieces of paper from the HP All-in-One, more
paper jams are likely to occur.
3.Replace the rear door. Gently push the door forward until it snaps into place.
