To begin the inkjet refilling process, please remove all empty cartridges from your printer. Firmly attach a piece of tape to the bottom of each cartridge making sure that the "ink exit holes" are properly covered. The "filling holes" are located on the upper side of the ink cartridge. They can be found underneath the label.

Use the tool provided in the kit to punch through and expose the recessed inkjet refill holes. Note: some cartridge sets have ball bearings instead. If this is the case, please push the bearing through the hole into the cartridge.

Fill the provided syringe with the appropriate color of ink. - Push it into the filling hole of the cartridge as far as it will go (making sure the tip has almost reached the bottom of the cartridge).

Slowly inject the ink into the cartridge while withdrawing the needle from the refilling hole.

It is time to stop when ink becomes visible at the top of the hole. Note: remove a small amount of ink from the cartridge so it is not flush with the top of the opening.

Do not reseal the filling holes.

Remove the tape from the ink exit holes, and return the newly filled cartridges to the printer making sure to run 1-3 cleaning cycles, and print head alignment tools.

If you have a cartridge with a smart chip, it is important to reset the printer chip to ensure they function properly. This can be done with an Epson chip resetter...

It is important to remember:

When ink cartridges are empty they must be stored in an airtight bag with a damp cloth to prevent the ink distribution sponges from drying out.

Cartridges cannot be refilled forever. For best results it is recommended to change your printer cartridges after every 5 refills. - Be sure to avoid touching metal contacts on each cartridge when handling them. Static charges and can damage cartridges rendering them useless
