The Epson Stylus C66 printer uses Epson T044120, T044220, T044320 and T044420 cartridges. There are two cartridges, one for black and one for colour. The colour cartridge contains yellow, magenta and cyan ink. Instead of spending money and buying new cartridges when the old run out, simply refill your old cartridges. The printer will notify you when the ink cartridges are getting low. Epson cartridges are some of the most difficult to refill because each one contains a memory chip. Besides refilling the cartridge, the chip must be reset.

    Refill Epson C66 Ink Cartridges

  1. 1

    Place paper towels on the table where you are refilling the cartridge. This protects the table from ink spills. Wear rubber gloves if you do not want to stain your fingers.

  2. 2

    Reset the memory chip in the cartridge with the Epson Chip Resetter. Insert the cartridge into the chip resetter. The pins on the resetter will come into contact with the microchip on the print cartridge. Ensure that the resetter is properly aligned. Hold the cartridge in place until the green LED light on the resetter flashes green. If the light does not flash, then ensure that all the pins are in contact with the microchip.

  3. 3

    Drill a hole with a thumb drill just above the H where it says "push" on the top of the cartridge. Drill a second hole at the upper right-hand corner of the label. The second hole is located just above the first hole. One hole is used to refill the cartridge, and the other is to let air out of the ink chambers.

  4. 4

    Push the plunger all the way down on the syringe. Place the tip in the ink and slowly draw the plunger back. The syringe will fill with ink.

  5. 5

    Insert the syringe needle into one of the drilled holes. It can be inserted a maximum of 1 centimetre into the cartridge.

  6. 6

    Push the plunger down very slowly. The ink needs to run through the different internal chambers of the ink cartridge. Filling the cartridge too fast will result in ink coming out of the air hole. Colour cartridges will need a maximum of 10ml of ink. A black cartridge takes 25ml of ink.

  7. 7

    Stop adding ink once you reached the maximum ink listed in Step 6 or when ink starts to bubble out of the second hole.

  8. 8

    Replace the cartridge into the printer, and let it sit in place for 24 hours. The ink will settle to the bottom of the cartridge and the air will rise to the top.
