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, do not remove them
unless they need to be 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.
