Theory - The ink in these cartridges are retained because
1. Put the cartridge on some paper towels in an area
2. With a rubber
band tightly put on the orange cap that covered the outlet port. 3. For the Black 902 cartridge fill
the syringe with 13 ml. of black
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. Another alternative method InstructionsStep 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 5) Replace the cartridge and run 1 -
3 cleaning cycles as per printer instructions.
