Open the ink door on the front of the printer and read the label on the cartridge already fitted — the Brother code (for example LC3717) is printed on the end face. You can also check the model badge on the front of the machine against the Compatible Printers tab above, or print a supplies or configuration page from the printer’s menu. If you are still unsure, message us the printer model and we will confirm it for you before you order.

It fits MFC-J3930DW, MFC-J2330DW, MFC-J3530DW and MFC-J2730DW. The full list is in the Compatible Printers tab above. If your model is not listed, please check with us before ordering rather than assuming a near-match — Brother part numbers change between otherwise similar models.

Brother quotes yields against ISO/IEC 24711, an independent test that prints a fixed reference page repeatedly and measures how many pages an ink cartridge produces. It is a comparison benchmark rather than a promise — heavy graphics, photos or dense text use more ink per page and reduce the figure, while light text stretches it. Per-colour figures for this family are listed in the Page Yield tab above.

Every ink cartridge we sell is sourced through official Brother distribution channels for the UAE and arrives in sealed Brother retail packaging. Genuine supplies keep your printer’s warranty valid — damage caused by third-party ink cartridges is generally not covered by Brother.

Choose the LC3719XL if you print regularly — it holds more ink for a smaller increase in price, so the cost per page is lower. The LC3717 makes more sense for light or occasional printing, where a large cartridge could sit part-used for a long time. Both fit the same printers, so you can switch between them at any time.

Yes. The LC3717 and LC3719XL are physically interchangeable and are listed by Brother for the same printer models — the higher-capacity version simply contains more ink. You do not need to change any printer setting when you switch.
