Genuine vs Compatible Ink Bottles
Choosing compatible 31 and 32XL ink bottles offers significant savings for everyday printing without compromising print quality. "Under Australian Consumer Law, using compatible cartridges does not void your printer warranty." All alternative supplies are thoroughly tested to match manufacturer performance.

Replacement Print Heads
The HP Smart Tank Plus 555 uses modular print heads, including the M0H50AA Black and X4E75AA Tri-Colour units, which house the thermal ink nozzles. Experience Tip: Replacing the print heads restores crisp text and vibrant colour saturation if physical nozzle wear occurs over extended high-volume bottle usage.

Refill Pro Tip
Never wait for ink tank reservoirs to dry out completely before topping up; keeping ink levels above the minimum fill line prevents air bubbles from entering the print head supply tubes.
Frequently Asked Questions
Do I need to replace M0H50AA or X4E75AA print heads every time I refill the ink bottles?

Can I mix compatible 31XL ink bottles with genuine HP ink in the tanks?
Yes, compatible 31XL and 32XL inks are fully chemically compatible with genuine HP ink formulations, allowing you to top up existing reservoirs without draining them.
How long can HP 31 and 32XL ink bottles be stored before opening?
Sealed HP ink bottles have a shelf life of up to 24 months when stored upright in a cool, dark environment away from direct sunlight.
