							Check the estimated ink levels
You can easily check the ink supply level to determine how soon you might need to 
replace a print cartridge. The ink supply level shows an estimate of the amount of ink 
remaining in the print cartridges. Actual ink levels may vary.
TIP: You can also print a self-test report to see if your print cartridges might need to 
be replaced.
NOTE: If the print cartridges were used before being installed in the product, or have 
been refilled, the estimated ink levels on the  Estimated Ink levels tab may be 
inaccurate or unavailable. 
NOTE: Ink from the cartridges is used in the printing process in a number of different 
ways, including in the initialization process, which prepares the product and cartridges 
for printing, and in print head servicing, which keeps print nozzles clear and ink flowing 
smoothly. In addition, some residual ink is left in the cartridge after it is used. For more
information, see www.hp.com/go/inkusage .
To check the ink levels from the HP Photosmart Software 
1. In the HP Solution Center, click Settings, point to Print Settings, and then click 
Printer Toolbox .
NOTE:You can also open the Printer Toolbox from the Print Properties dialog 
box. In the  Print Properties dialog box, click the Features tab, and then click the 
Printer Services  button.
The Printer Toolbox appears. 
2. Click the Estimated Ink Level tab. 
The estimated ink levels for the print cartridges appear.

Replace the print cartridges
When the ink level for the print cartridge is low, a message appears on your computer 
screen. You can also check the in k levels by using the software installed with the HP All- 
in-One. Follow these instructions when the ink level is low.
NOTE: Ink level warnings and indicators provide estimates for planning purposes 
only. When you receive a low-ink warnin g message, consider having a replacement 
cartridge available to avoid possible printing delays. You do not need to replace the 
print cartridges until print quality becomes unacceptable.
To order print cartridges for the HP All-in-One, go to www.hp.com/buy/supplies . If

Use ink-backup mode
Use the ink-backup mode to operate the HP All-in-One with only one print cartridge. The 
ink-backup mode is initiated when a print cartridge is removed from the print cartridge 
carriage. During ink-backup mode, the product can only print jobs from the computer. 
You cannot initiate a print job from the control panel (such as copying or scanning an
original).
NOTE: When the HP All-in-One operates in ink-backup mode, a message is 
displayed on screen. If the message is displayed and two print cartridges are installed 
in the product, verify that the protective piece of plastic tape has been removed from 
each print cartridge. When plastic tape covers the print cartridge contacts, the product 
cannot detect that the print cartridge is installed.

Store the print cartridges
Follow these guidelines to maintain and store HP print cartridges and to ensure consistent 
print quality. 
• When you remove a print cartridge from the product, store it in an airtight plastic 
container to prevent the ink from drying out. 
• Keep all unused print cartridges in their original sealed packages until they are 
needed. Store print cartridges at room temperature (15–35 degrees C or 59–95
degrees F). 
• Do not remove the plastic tape covering the ink nozzles until you are ready to install 
the print cartridge in the product. If the plastic tape has been removed from the print 
cartridge, do not attempt to  reattach it. Reattaching the tape damages the print 
cartridge.
CAUTION: Always turn the product off with the On button before you unplug the 
power cord or turn off a power strip. This allows the product to store the print cartridges 
properly. When you store the product, always  leave the active print cartridges inside 
the product.
Align the print cartridges
Aligning the print cartridges ensures high-quality output. The HP All-in-One prompts you
to align and calibrate the print cartridges every time you install a new print cartridge. Make
sure you align the print cartridges when prompted to ensure excellent print quality.
NOTE: If you remove and reinstall the same print cartridge, the HP All-in-One will 
not prompt you to align the print cartridges. The HP All-in-One remembers the 
alignment values for that print cartridge, so you do not need to realign the print
cartridges.

Clean the print cartridge contacts
CAUTION: Do not clean the print cartridge contacts unless you are having a problem 
with print quality and other measures have not been successful. For more information,
see  “Print quality troubleshooting” on page 98.
Clean the print cartridge contacts if you get repeated messages on your computer screen 
prompting you to check a print cartridge after you already have cleaned or aligned the
print cartridges, or if the Check Print Cartridge light is blinking. 
Before cleaning the print cartridge contacts, remove the print cartridge and verify that 
nothing is covering the print cartridge contacts, then reinstall the print cartridge. If you 
continue to get messages to check the print cartridges, clean the print cartridge contacts. 
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 use platen cleaners or alcohol to clean the print cartridge 
contacts. These can damage the print cartridge or the product.

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 in clude 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 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.
