Epson 138 Ink Cartridges

Expected page output and replacement cycles

Epson 138 ink cartridges are rated according to ISO/IEC 24711 standards for inkjet printing. The Black cartridge yields approximately 380 pages, while the Cyan, Magenta, and Yellow cartridges yield up to 420 pages based on 5% page coverage under standard operating conditions.

What to know about compatible cartridges

Using compatible Epson 138 cartridges provides significant savings for high-volume text and everyday colour documents. Under Australian Consumer Law, using compatible cartridges does not void your printer warranty.

Pro Tip

Epson individual ink printers require all four ink slots (Black, Cyan, Magenta, and Yellow) to contain a recognised cartridge with available ink before printing any job, even monochrome text.

Match Your Printing Habits to the Right Epson 138 Ink Cartridge Pack

Watching the budget? Compatible cartridges match the fit and yield of genuine ink at a lower price, from $13.43 for a single 138 cartridge or 4-pack 138 for $46.20.

For a high-volume office, buying in bulk cuts the cost per unit further - the 5-Pack 138 Compatible (from $60.44) works out cheapest per cartridge.

Frequently Asked Questions

Can I print in Black if one of the colour 138 cartridges is empty?

No. Epson four-colour print systems require active ink signals across all four cartridges to run periodic maintenance cycles and protect the permanent printhead from drying out.

Why do Cyan, Magenta, and Yellow cartridges deplete during text printing?

Epson printers periodically flush small amounts of ink across all nozzles during head maintenance to maintain print quality, which consumes slight amounts of colour ink even on pure Black documents.

How should spare Epson 138 compatible cartridges be stored?

Keep cartridges sealed in their original vacuum packaging at room temperature, upright, and away from direct sunlight to prevent air pockets from forming near the ink outlet valves.

Is C13T138192 the same as Epson 138 Black?

Yes, C13T138192 is Epson's official part number for the standard 138 Black ink cartridge. Both codes refer to the exact same cartridge model and fit identical printer slots.
