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.
