Epson EcoTank WorkForce ET-4750 Ink Bottles
Your Epson EcoTank WorkForce ET-4750 uses the 502 cartridge series, which replaces standard desktop print modules with high-capacity refill bottles. As demonstrated by our 4.8 Google rating, we are committed to providing premium consumable cartridges. Having supplied dependable printing solutions for this printer since Nov 2017, we understand the long-term replacement behaviour of home office users who require balanced ink flow for continuous administrative duties without facing sudden empty-tank interruptions.
What to expect from each cartridge type
Real-world document longevity is governed by the specific layout density printed, but standard manufacturer output ratings conform to the ISO/IEC 24712 test metric for continuous fluid delivery configurations. Because these refill bottles contain massive ink volumes compared to classic desktop storage modules, users can complete extensive print runs before tracking fluid lines.

Choosing between genuine and compatible options
Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. Opting for premium third-party ink refills offers a direct path to minimizing daily printing costs while sustaining crisp monochrome text and vibrant graphic reproduction. To understand the operational characteristics of both options, read our detailed genuine vs compatible cartridges.
Managing continuous fluid supplies
Workplaces handling an even mix of marketing drafts and multi-page text forms usually achieve the best balance by purchasing full four-bottle value packs. For users printing text records exclusively, running standalone black bottles alongside the multi-packs prevents individual colour imbalances. All compatible bottles from our online catalogue carry a secure money back guarantee. Free delivery applies on all orders over $99 (conditions apply), shipped quickly from regional logistics hubs in Perth, Brisbane, Sydney, Melbourne, and Adelaide.

Pro Tip
When carrying out a refill, insert the bottle directly without squeezing the plastic body, as the automatic gravity-fed nozzle valve cuts off the fluid flow independently when the reservoir reaches full capacity, whereas physical squeezing can cause air pocketing or overfill spillage.
Frequently Asked Questions
Are the tips of the genuine and compatible T502 bottles uniquely keyed for each colour?
Yes, the T502 refill system employs a physical slot-and-key design on each bottle nozzle that only fits the corresponding colour port on the printer reservoir, preventing you from accidentally pouring the wrong ink colour into a tank.
Why is the black 502 ink bottle formulated differently from the cyan, magenta, and yellow bottles?
The black fluid uses a pigment-based engineering structure to produce highly durable, smudge-resistant text for professional documentation, while the three colour variants utilise dye-based fluids to ensure smooth, vibrant colour mapping on plain paper.
Can I top up the printer reservoirs before they are fully depleted?
Yes, you can refill any of the four ink channels at any stage before the fluid drops to the lower line, which is recommended to keep the internal delivery lines pressurised and completely free of air pockets.
