Step 1: The Tools/Supplies
Small Drill Bit
Ink Re-Fill kit
Empty Ink Cartridge
Step 2: Drill
so that you can fill the cartridge with new ink.
I messed up on making the hole, you have to drill it close to the 'front' of the cartridge.
Step 3: Fill er' Up
Lay down a paper towel then,
Fill your syringe with 10ml ink and fill your cartridge.
Step 5: Test the Cartridge
After your printer has stopped calibrating itself, you'll need to test your handiwork.
Print the attached file, if it comes out completely black, with no fading, you are good
if you have fading across the page, you need more ink.
