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 device and cartridges
for printing. In addition, some residual ink is left in the cartridge after it is used. For

Handle the print cartridges
Before you replace or clean a print cartridge, you should know the part names and how
to handle the print cartridges.
1 Copper-colored contacts
2 Plastic tape with pink pull tab (must be removed before installing)
3 Ink nozzles under tape
Hold the print cartridges by their black plastic sides, with the label on top. Do not touch
the copper-colored contacts or the ink nozzles.
NOTE: Handle the print cartridges carefully. Dropping or jarring cartridges can cause
temporary printing problems, or even permanent damage.
Replace the print cartridges
Follow these instructions when the ink level is low.
NOTE: When the ink level for a print cartridge is low, a message appears on the
display. You can also check the ink levels by using the printer Toolbox (Windows) or
the HP Printer Utility (Mac OS).
