Tips and Tricks refill Brother inkjet cartridge

These tips are mostly common-sense, but the refilling method is perhaps unique. It helps you to ensure that your cartridge is filled properly with minimal chance of ink leakage when cartridge replaced in your Brother Printer.
Caution: ensure your replacement ink is high quality with correct viscosity otherwise you will be forever print head cleaning.
I strongly recommend replace cartridge with genuine Brother after at most 5 fills, to ensure non deterioration of cartridge seals.
