Empty cartridges left for more than 3 days do not always give a successful re-fill.

Please check before filling that your colours correspond with the instructions.

Assemble the needle and syringe, place the needle into the ink inlet hole and push until slight resistance is felt. Remove the needle from the cartridge, this will allow you to see a small amount of colour on the needle.

If the colours are different from those on the instructions supplied, then fill the chambers as per the appropriate colour sequence in your cartridge.

Put the cartridge on some paper towels in an area where you can tolerate a spill.

Peal off the top label.

Very S-L-O-W-L-Y inject ink into each chamber until the sponge is full. A little ink might come out of the top when full, so cover up the other two holes while filling one.

When finished, replace the top label or leave it off (it will make no difference in the printing).

Replace the cartridge and run 1 - 3 cleaning cycles as per printer instructions.

If necessary leave cartridge in printer for up to 8 hours.

The cartridge will print just like a new one. Even though the cartridge prints correctly, the ink level gauge will not read full after a refill. It is possible to  reset the ink level gauge back to full but it does not work on every cartridge.
This will allow you to reset the ID system & Ink Level Indicator built into the printer.
