Refilling Hewlett Packard HP 303, HP 303XL, HP 305 or HP 305XL Tri-Colour Ink Cartridges

Refilling Hewlett Packard HP 303, HP 303XL, HP 305 or HP 305XL Tri-Colour Ink Cartridges

Refilling the HP 303, HP 303XL, HP 305 or HP 305XL tri-colour ink cartridge at home is very easy and can offer you great results, with very little equipment. All you need is at least one syringe, plus some universal cyan, magenta and yellow ink. Simply remove the label, widen the fill holes (if necessary) and fill the relevant chambers of the HP 303, HP 303XL, HP 305 or HP 305XL ink cartridge with the amount of ink mentioned below.

When refilling the Hewlett Packard ink cartridges below, we recommend injecting the following amount of ink into the respective cyan, magenta and yellow chambers:

HP 303/T6N01AE: 3ml (9ml Total)
HP 303XL/T6N03AE: 3ml (9ml Total)
HP 305/3YM60AE: 3ml (9ml Total)
HP 305XL/3YM63AE: 3ml (9ml Total)

Even though the original HP 303, HP 303Xl, HP 305 or HP 305XL contain different amounts of ink, the sponges within are the same size, so you can use the 3ml of cyan, magenta and yellow ink (9ml total) in either type of cartridge when refilling.

This guide is intended purely to show where to inject the ink into these cartridges and how much we recommend using. For full refill instructions for these cartridges, please click here.

In all likelihood, you will be able to fit more ink in the HP 303XL, but we are yet to get our hands on sufficient empties to experiment. We will endeavour to update this article and produce new videos when we have them, but would recommend you playing safe with this lower fill for now.
