Original vs. Compatible Cartridges

When buying ink for your Brother MFC-J5945DW, you typically have two main options:

Original (OEM) Cartridges

Manufactured by Brother. These offer guaranteed reliability and print quality but typically come at a higher price point. They are the best choice for printing high-resolution photos or archival documents.

Compatible / Remanufactured

Made by third-party companies. These are often significantly cheaper than original cartridges. Quality can vary between brands, but reputable suppliers offer guarantees. These are often a cost-effective choice for everyday document printing.

When to Replace Your Ink

You should look into replacing your cartridges when print quality begins to fade, colors appear missing, or your printer displays a "Low Ink" warning. For inkjet printers like this, it is recommended to replace cartridges as soon as quality drops to prevent the printhead from drying out or clogging.

Tip: If you print infrequently, run a print head cleaning cycle once every few weeks to keep the ink flowing smoothly and prevent blockages.
