Theory - The ink in these cartridges are retained because
the cartridges have an internal
sponge.
(see
picture above)
1. Put the cartridge on some paper towels in an area
where you can
tolerate a spill.
2. With a rubber
band tightly put on the orange cap that covered the outlet port.
If you no longer have the orange cap then put on a vinyl glove and put your
finger over the outlet port.
This will prevent ink from dripping out while you refill.
3. For the Black 902 cartridge fill
the syringe with 13 ml. of black
ink.
For the Color 902 cartridge fill
the syringe with 8 ml. of the appropriate color of ink.
4. Drill a hole into the colored circle that has
either K (black) or C (cyan) or M (magenta) or Y (yellow) on top of the
cartridge.
5. Put the syringe
needle at least half way down into the drilled hole and very S-L-O-W-L-Y inject ink.
6. After the ink is injected keep the
orange cap on or keep your finger over the outlet port for another minute.
This will give the ink time to soak up into the sponge.
7. Now take off the
orange cap or remove your finger from the outlet port and leave the drilled
hole open.
8. Put the cartridge(s)
back into the printer and run 1 - 3 cleaning cycles
as per printer instructions.

On the 902 series cartridges,
there is an electronic counter embedded in a small computer chip/board. This
counter starts at a high number and decreases for every character printed.
Eventually, the counter reaches zero. At this point, an error message is
generated by the printer. If you click "OK" to the error message, the
printer will continue to print. However, the ink level display will not show
correctly with that cartridge.
On some HP printers, simply click
through the error message and the various warnings. The printer should then
print fine. Notice that you will need to do this again when the other
cartridges run out of ink.
On other HP printers, hold the RESUME
or RESET button for about 10-15 seconds. This should reset the printer so
that it will print with the refilled cartridge.
Another alternative method
Instructions
Step 1) Put the cartridges on some paper towels in an area where you can tolerate a
spill.
Step 2) Turn the cartridge up side down so that the
outlet port of the cartridge is facing upward.
Step 3) Fill the syringe
with the appropriate color of ink
Step 4) Drip ink onto the felt pad in the outlet port.
The felt pad will quickly absorb the ink into the cartridge. If the felt pad
will not soak up any more ink and the ink just sits on top or you see some
ink coming out of the vent hole located on the opposite side then the sponge
is full. Dab a paper towel onto the felt pad to soak up any ink that did not
get absorbed into the cartridge.
It goes without saying that you want to put the correct color into the
correct chamber. Don't drip yellow ink onto the cyan felt pad and wonder why
you are now getting green.
Note: Do not pierce the felt pad with the needle of the syringe.
Step 5) Replace the cartridge and run 1 -
3 cleaning cycles as per printer instructions.

If necessary leave cartridge in printer for up to 4 hours
to allow the ink to saturate the entire sponge.
