piece of paper. This means that if you were to print images or large blocks of colour or text, your cartridge will run out much faster.
FAQs
How do I connect my MFC Brother printer to wi-fi?
The easiest way to connect your Brother MFC-9840CDW printer to wifi is by using your printer control panel. Find ‘Network Settings’ in the menu and find the ‘wireless setup’ or ‘WLAN setup’
option. The screen will then guide you step-by-step through entering your Wi-Fi network name and password. Your printer will then attempt to connect, and you should see a confirmation message
once successful.
Can you use any toner with Brother MFC-9840CDW printer?
No, you’ll need to use the toner cartridges specifically designed for the Brother MFC-9840CDW printer (which are the TN135 products listed on this page). This is because each Brother printer
model has unique specifications, so each uses a different toner cartridge and drum unit. However, you can use toner cartridges from any trusted manufacturer as long as they are compatible with
the Brother MFC-9840CDW printer. Often third-party cartridges are a preferred option for customers as they come at a lower price point but produce the same print results.

Do you sell laser printer maintenance kits?

Hi there, we do sell maintenance kits but mostly for HP and Lexmark printers. I don't think we can get them for Brother machines.
Q
Is the TN135P cartridge pack a genuine Brother cartridge or a compatible? I want to make sure I buy Brother cartridges because of my warranty.

Hi Tina, the TN135P cartridge Pack is an original Brother cartridge set, however, there are great savings if you buy the Compatible version with the reference RETN135P and there's no need to worry because using our compatible cartridges in your printer won't affect your warranty. Just for your peace of mind if anything did go wrong (which has never happened in my 9 years in the business) then we would be more than happy to arrange for an engineer to fix your printer and if it can't be fixed then we'll replace it with a brand new one! :)
