Epson NX635 Ink Cartridges
Shop ink cartridges for your Epson Stylus NX635, which uses the Epson 138 ink cartridges series. Ink Depot has supplied quality consumables for this printer since Nov 2013. Our 4.8 Google rating shows that our customers consistently receive high-quality cartridges backed by reliable performance. Designed for home office document printing, this unit relies on individual tanks like C13T138192 Black and C13T138292 Cyan, so you only replace empty colours.
Expected Page Yield and Output Performance
Epson calculates page yields for 138 ink cartridges using ISO/IEC 24711 standard testing methods for inkjet printing. Actual cartridge output depends on document density, print head cleaning cycles, and overall page coverage during daily use.
| Cartridge Number | Type | Colour | Page Yield | Cost Per Page |
|---|---|---|---|---|
| 138 | High Yield | Black | 380 | $0.035 |
| 138 | High Yield | Cyan | 420 | $0.032 |
| 138 | High Yield | Magenta | 420 | $0.032 |
| 138 | High Yield | Yellow | 420 | $0.032 |
Cost Per Page = Total Cartridge Price ÷ Page Yield (at 5% coverage). Prices based on Compatible cartridges.
Understanding Compatible Epson 138 Cartridges
Compatible 138 ink cartridges offer an economical alternative for daily document printing while maintaining crisp text and accurate colours. Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. Every compatible cartridge is manufactured to fit seamlessly into your printer.

Ordering Options and Australian Delivery
For routine document printing, purchasing multipacks like the C13T138695 four-colour set reduces overall replacement costs compared to single units. If you primarily print black text, stock extra C13T138192 cartridges to avoid running out mid-job. All compatible products include a money-back guarantee under our returns policy. We dispatch directly from local warehouses in Perth, Brisbane, Sydney, Melbourne and Adelaide to ensure prompt transit. Free delivery applies on all orders over $99.

Pro Tip for Epson 138 Inks
Always leave empty cartridges installed in the printer until you are ready to insert a replacement, as leaving a slot empty can dry out the integrated ink delivery nozzles.
