Remove the cartridge from the printer, clean the outlet area with a paper towel and seal the outlet holes with a fresh piece of adhesive tape.

Locate the filling holes underneath the label but do not remove the label itself

With the empty blunt tipped filling tube, puncture the label exposing the filling holes.

Following the instructions, insert the blunt filling tube as far as possible and inject the proper colour into each chamber. The slower you inject, the more ink the sponge will absorb.

Stop when ink appears at the fill opening. Pull back on the plunger slightly to prevent spillage. Caution: Overfilling will cause cross contamination of colours, ruining the cartridge.

Do not remove the sealing tape from the outlet holes and do not seal the filling holes you created.

When each chamber has been filled set the cartridge upright on a non-absorbent surface for 24 hours then install the cartridge into the printer as new. Run at least 2 printer cleaning cycles to return print quality to normal.
