maintaining print cartridges The following suggestions will help maintain HP print cartridges and ensure consistent print quality: q Keep all print cartridges in their sealed packages in an upright position until they are needed. Print cartridges should be stored at room temperature (60-78 degrees F or 15.6-26.6 degrees C). q Do not remove the plastic tape covering the ink nozzles until you are ready to install the print cartridge in the printer. If the plastic tape has been removed from the print cartridge, do not attempt to reattach it. Reattaching the tape damages the ink nozzles. q If print cartridges are removed from their sealed containers, store them in an airtight container. For best results, store the black cartridge with the nozzle side up and the color cartridge with the nozzle side down. Do not allow anything to touch the nozzle plate. q Once the print cartridges are installed in the printer, leave them in the print cartridge cradle unless they are being manually cleaned. This prevents ink from evaporating or clogging the print cartridges. q Do not unplug the printer until printing is complete and the printer is turned off. Use the Power button to turn off the printer.

maintaining print cartridges
The following suggestions will help maintain HP print cartridges and ensure consistent
print quality:
Keep all print cartridges in their sealed packages in an upright position until
they are needed. Print cartridges should be stored at room temperature (60–78
degrees F or 15.6–26.6 degrees C).
Do not remove the plastic tape covering the ink nozzles until you are ready to
install the print cartridge in the printer. If the plastic tape has been removed
from the print cartridge, do not attempt to reattach it. Reattaching the tape
damages the ink nozzles.
If print cartridges are removed from their sealed containers, store them in an
airtight container. For best results, store the black cartridge with the nozzle
side up and the color cartridge with the nozzle side down. Do not allow
anything to touch the nozzle plate.
Once the print cartridges are installed in the printer, leave them in the print
cartridge cradle unless they are being manually cleaned. This prevents ink from
evaporating or clogging the print cartridges.
Do not unplug the printer until printing is complete and the printer is turned off.
Use the
Power
button to turn off the printer.
