Print Cartridges: Storing Print Cartridges

Storing Print Cartridges

To maintain excellent print quality from your print cartridges:

• Keep all print cartridges in their sealed packages, at room

temperature (60-78° F or 15.6-26.6° C), until you are ready to

use them.

• Once installed, leave the print cartridges in their cradle at all

times to keep them from drying out or becoming clogged.

• Store unsealed print cartridges in an airtight plastic container.

• Do not unplug the printer until printing is complete and the print

cartridge cradles have returned to their home position on the

right side of the printer. The print cartridges will dry out if not

stored in their home position.

• Do not attempt to reattach the vinyl tape previously removed

from the print cartridges. Reattaching the tape will damage the

cartridges.

Only use the Power Button

on the front of the

printer to turn the printer on and off. Using a power

strip, surge protector, or a wall-mounted outlet switch to turn the

printer on and off may cause premature failure.

Cleaning Print Cartridges

When Do You Need to Clean?

Clean the print cartridges if your printed page is missing lines or

dots, or if it contains ink streaks.

If You See Missing Lines or Dots

Clean the print cartridges from the HP DeskJet

Toolbox by doing the following:

1 Open the HP DeskJet Toolbox. For more

information, see “HP DeskJet Toolbox” on page 13.

2 Click Clean the Print Cartridges and follow the on-screen

directions.

Note:

Unnecessary cleaning wastes ink and shortens the life of the

print cartridge.
