Epson T40W Ink Cartridges
Your Epson Stylus Office T40W uses the 103 series ink cartridges alongside standard 73N options. Designed for wireless office document output, this printer runs an individual four-colour ink system. Upgrading from standard T1051 black cartridges to high-yield T1031 alternatives substantially reduces print costs during continuous document runs. Our 4.8 Google rating reflects a long-standing track record of premium cartridge performance.
Expected Page Output and Replacement Cycles
Page yields for high-yield 103 series and standard 73N ink cartridges are measured using ISO/IEC 24711 standard test protocols under continuous print testing. High-yield T1031 black cartridges contain significantly higher ink volume than standard T1051 cartridges, substantially reducing cartridge changeovers for office document workflows.

Choosing Between Genuine and Compatible Options
Compatible cartridges offer a cost-effective choice for everyday office document printing without compromising text sharp clarity. Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. Learn more about performance differences in our genuine vs compatible cartridges guide.
Selecting the Right Cartridge Setup
If you print mainly text documents and invoices, fitting high-yield T1031 black cartridges provides the lowest operating cost per page. If you print occasional colour charts or mixed media, standard 73N colour cartridges (T1052, T1053, T1054) offer a low upfront cost. Compatible cartridges are backed by a money back guarantee for peace of mind. Browse our full range of Epson ink cartridges online.

Pro Tip
When replacing cartridges on the Epson Stylus Office T40W, always install high-yield 103 series black cartridges (T1031) instead of standard 73N black (T1051) if you print heavily; the high-yield cartridge fits into the identical physical slot while delivering more than four times the printed pages.
Frequently Asked Questions
Can I mix 103 high-yield cartridges and 73N standard cartridges in the same printer?
Yes. The Epson Stylus Office T40W recognises each cartridge slot independently, allowing you to run a high-yield T1031 black cartridge alongside standard 73N cyan, magenta, and yellow cartridges without issue.
Why does the T1031 black cartridge offer a lower cost per page than the T1051?
The T1031 extra high-capacity cartridge contains over four times the usable ink volume of a standard T1051 cartridge, yielding approximately 995 pages compared to 230 pages while sharing the exact same slot dimensions.
What should I do if a compatible cartridge is not recognised upon installation?
Remove the cartridge, inspect the gold chip contacts on the base to ensure they are clean, reinsert the cartridge firmly until it clicks into place, and power cycle the printer to reset the reader.
