Although the image above shows the most common arrangement some of these cartridges actually have a different colour layout on the inside. If this is your first time refilling the cartridge I would recommend probing it with a straightened paperclip to confirm the colours are all where they should be.
For these cartridges we recommend injecting the following amount of ink into each of the chambers (photo black/photo cyan/photo magenta):
HP 110/CB304AE: 3ml (9ml Total)
We recommend sticking to the lower fill for these cartridges as some have a smaller sponge and are physically restricted inside the cartridge. As such over filling them can result in ink spilling inside your printer.
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.
