Expected Page Output and Replacement Cycles

Page yields for Epson T502 ink bottles are measured using ISO/IEC 24711 test standards under continuous printing. Black T502 bottles provide expansive coverage for high-volume text output, while cyan, magenta, and yellow bottles deplete at lower rates during standard office document tasks.

Cost Per Page = Total Cartridge Price ÷ Page Yield (at 5% coverage). Prices based on Genuine cartridges.

Choosing Between Genuine and Compatible Options

Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. Choosing compatible T502 ink bottles delivers substantial savings for daily document production while maintaining vivid output across text and graphics. Learn more about performance standards in our guide to genuine and compatible cartridges.

T04D100 Maintenance Box Options

The T04D100 maintenance box collects excess ink flushed during printhead cleaning cycles. Experience Tip: The T04D100 maintenance box is a dedicated user-replaceable component designed to handle waste ink management independently of the ink bottle supply.

Best Way to Stock These Cartridges

For daily office text printing, stocking T502 black bottles ensures uninterrupted productivity, whereas balanced colour printing requires keeping cyan, magenta, and yellow spares on hand. Choosing compatible T502 bottles offers substantial savings backed by a money back guarantee. Review our returns policy for total peace of mind. All orders of genuine and compatible Epson ink bottles ship fast from our warehouses in Perth, Brisbane, Sydney, Melbourne and Adelaide. Free delivery applies on all orders over $99.

Pro Tip

Pro Tip: Store unopened T502 ink bottles upright in a cool, dark location and refill ink reservoirs before levels drop to the lowest line on the front tank window to maintain proper ink pressure.

Frequently Asked Questions

Can I mix genuine and compatible Epson T502 ink bottles in the same printer?

Yes, you can safely pour compatible T502 ink into an EcoTank reservoir that previously contained genuine Epson 502 ink without chemical reaction or print issues.

What happens if I top up the ET-3700 ink reservoirs before they are completely empty?

Topping up T502 ink before reservoirs empty is recommended; EcoTank reservoirs are designed for refills at any stage, ensuring continuous fluid supply to the printhead without waiting for low-ink warnings.

How does the keylock nozzle design work on T502 ink bottles?

Each T502 bottle tip is uniquely keyed to fit only its corresponding colour tank port on the EcoTank ET-3700, preventing accidental cross-colour contamination during refilling.

I recently purchased a Epson maintenance kit from the store, and I couldn’t be happier with my online shopping experience. Their website was user-friendly, making it easy to find the perfect item. The checkout process was smooth, and I received my order promptly. The product arrived in excellent condition, exactly as described on their website. I’m thrilled with the quality and will definitely shop again in the future. Highly recommended!”
