How to refill Epson SureColor P600 cartridges (T760)

Each refillable cartridge has three parts you need to know before you start.

• Refill plug: remove it to add ink, and put it back when you finish.
• Air vent plug: must be removed whenever the cartridge is installed in the printer. It lets air in so ink can flow out.
• Reservoir: the chamber that feeds the printer. It must contain ink at all times.

Cartridges that arrived already filled with ink (Ready2Go kits) are primed for you. Skip the priming steps and go to "Remove the air vent plug and install".

Empty cartridges must be primed before their first use. After that, priming is not needed again at refills.

1. Attach the adapter to the syringe.
2. Draw about 8 to 10 ml of ink into the syringe.
3. Remove the refill plug.
4. Hold the cartridge upright and push the syringe tip up into the outlet hole on the bottom until it meets some resistance.
5. Push about 1/8 in further, against the valve inside.
6. Inject the 8 to 10 ml of ink.
7. Withdraw the syringe and tip.

1. Add ink through the refill hole to finish filling the cartridge.
2. Push the refill plug back in.
3. Check the reservoir chamber. On a properly primed cartridge it is at least half full of ink.

Remove the air vent plug, then install the cartridge in the printer like a normal cartridge.

These cartridges use auto reset (ARC) chips. The chip resets itself to full only after the printer has run it down to empty. At that point the printer shows a cartridge not recognized warning for that color.

Removing and reinserting a cartridge before this warning does not reset the chip. The printer and the chip control this, and you cannot force it by hand.

Refill as soon as the warning appears.

1. Remove the cartridge that the printer reports as not recognized.
2. Remove the refill plug.
3. Fill the cartridge with the correct color.
4. Push the refill plug back in.
5. Check that the air vent hole is open.

Put the cartridge back in the printer. Because the printer had run the chip down to empty, removing and reinserting the cartridge resets the chip to full.

The cartridge is now full of ink and the chip reads full, so the ink level shown matches what is really inside.

While you are refilling one color, top up all the others too.

1. Remove the refill plug on each cartridge. The cartridge can stay in the printer.
2. Add ink until the cartridge is full.
3. Push the refill plug back in.

Topping up does not reset those chips. Each chip still resets only when the printer reports that cartridge as not recognized. Topping up protects the printer if an ink level estimate is wrong.

Print a nozzle check before you go back to printing, to confirm that every color is flowing.

If the reservoir of a cartridge empties completely, the cartridge must be primed again. This is never needed as long as the cartridges are kept topped up.

1. Prime the cartridge through the outlet with 8 to 10 ml of ink, as in First-time setup.
2. Finish filling through the refill hole and replace the refill plug.
3. Reinstall the cartridge with the air vent hole open.
4. Run head cleanings until the nozzle check is good again. It can take several, because air has to be purged from the ink tubes.

Each switch between Photo Black and Matte Black uses ink. Before a switch, the printer checks the chip level of the black it is switching to. If that chip reads too low, the printer refuses the switch. The chip cannot reset until it has been used down to empty, so you can end up stuck.

• Do not switch away from a black while its chip shows a very low level.
• Keep your original Epson black cartridges as recovery items. Take them out well before they reach low or empty, and store them.
• If you get stuck, install a black cartridge with a fuller reading, such as one of those original cartridges.

Print a document or a nozzle check at least once a week. Regular use keeps the nozzles clear. Printing twice a week also uses less ink overall, because the printer runs fewer maintenance flushes.

Keep switching between Matte Black and Photo Black to a minimum.
