Why should I use genuine Brother ink cartridges?

Genuine Brother cartridges are engineered for the MFC-J5845DW printhead and firmware. They help maintain accurate colour, reduce banding and clogging, and support proper ink level reporting. Using original LC3337 and LC3339XL cartridges also keeps the printer’s cleaning cycles and maintenance routines operating as intended.

What is firmware and why does it matter for Brother printers?

Firmware is the internal software that controls how your printer operates — from print quality and colour management through to ink detection, cleaning cycles and security.

Keeping firmware up to date can: • Improve reliability and print consistency • Fix known errors or bugs • Maintain security features • Ensure new cartridges are recognised correctly

Genuine Brother LC3337 / LC3339XL cartridges are designed to remain compatible after firmware updates, whereas non-genuine cartridges may fail or trigger error messages.

Can I use generic or compatible LC3337 / LC3339XL cartridges?

While generic cartridges may fit physically, they can cause issues such as: • “Cannot Detect Ink” or similar error messages • Loss of compatibility after a firmware update • Inconsistent colour or streaky prints • Increased risk of printhead clogging

For the most reliable results and to avoid compatibility problems, we recommend genuine Brother LC3337 and LC3339XL cartridges.

Does the Brother MFC-J5845DW support USB printer cables?

Yes. The MFC-J5845DW can be connected via USB. A USB printer cable provides a stable, direct connection and is often recommended for initial setup or where Wi-Fi is not available or reliable.
