Using the Inkjet Print Cartridge
Storage Container
You can use either the color inkjet print cartridge
supplied with the printer (HP51625A), or either of the
following black inkjet print cartridges, purchased
separately: large black (HP51626A) or black
(HP51626G). However, you can only use one of these
inkjet print cartridges in the printer at one time.
Always store the inkjet print cartridge that is not
currently being used in the storage container. The
storage container protects the ink nozzles from
damage and prevents the ink from drying out
while the inkjet print cartridge is not in use. This
prolongs the life of the inkjet print cartridge,
protecting your investment.
1.
Determine which inkjet cartridge you are storing:
• To store the black
inkjet print cartridge,
make sure the arrow on
the top of the black
inkjet print cartridge
points toward the
cartridge clip on the left
of the storage container.
• To store the color inkjet
print cartridge, make
sure the arrow on the
top of the color inkjet
print cartridge points
toward the cartridge clip
at the back of the
storage container.
2. When removing an inkjet print cartridge from
the storage container, be sure that the
cartridge clip is disengaged, then lift the print
cartridge out of the storage container.
