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

Using the eyelet screw provided (or a power drill with a 3/32 inch bit) drill a hole between the sealed filling holes. Alternatively, with an awl or other hard blunt object push the sealing bearings into the cartridge.

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

Seal the filling holes with adhesive tape.

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.
