Take out the empty ink cartridge from the printer. Open up the empty cartridge’s ink refilling hole by removing its label.
2. For tri-color cartridges, find the correct ink refilling hole and tape the other holes to prevent accidental ink color mix-up. The refilling holes for tri-color cartridges generally follow this arrangement, from right to left: Cyan, Magenta, and Yellow.
3. Prepare the Ink Bottle for the empty cartridge and extract ink from the bottle using an injection. Draw out 10ml ink for black ink cartridges and 5ml for color cartridges. Adjust ink volumes accordingly, depending on the specific brand of your cartridges.
4. Insert about 0.25” of the needle tip inside the refilling hole and then slowly inject the ink into the cartridge.
5. Detach the plunger from the syringe and wash both of them thoroughly on running water from your sink faucet. Please make sure that the needle doesn’t touch you or the sink to avoid ink stains.
6. Repeat the same steps for each of the other Color Cartridges that you want to refill. Cover up the ink refilling hole with cellophane tape.
7. Locate the chip, which resembles a small circuit panel at the back of the cartridge. Press the chip’s locking clip with a paperclip or ballpoint to release it from the cartridge. Push the chip against the cartridge during the process.
8. Prepare the new chip and take it out from its packaging. Hold the chip from its rear sides and install it into the cartridge. Use the locking clip to secure the chip into place.
9. Reload the newly refilled ink cartridge into the printer.
