Brother MFC-L9670CDN: Setup, Drivers, Ink and Common Problems

Is the Brother MFC-L9670CDN right for you?

The MFC-L9670CDN is the top of Brother's current color all-in-one range, adding a 10.1-inch tablet-style touchscreen and support for the 15,000-page TN-815 cartridges over the MFC-L9610CDN. It is an enterprise device placed under managed print contracts, with workflow apps and card authentication. Print and scan speeds match its sibling at 42 ppm. Home and small-office buyers will find it far beyond their needs.

Best for: Enterprise departments needing a managed color MFP with the biggest toner yields

Setting up the Brother MFC-L9670CDN

Deploy over Ethernet with server-hosted PCL6 or PostScript drivers, set admin credentials, and configure LDAP, scan-to-SharePoint and authentication. The large touchscreen hosts custom Brother Solutions Interface apps. Leave firmware management to the service partner.

1. Unbox and prepare. Remove every piece of shipping tape and packing material, install the toner cartridge and drum unit, and load paper in the tray.
2. Join your Wi-Fi. Keep the printer close to the router for setup. Most printers only connect to the 2.4GHz band, so if your router broadcasts one merged network name you may need to split the bands temporarily. See our Wi-Fi guide if it will not join.
3. Install the setup app. Use Brother's official app rather than a driver you found on a search result — third-party driver sites are the most common source of printer malware.
4. Add the printer. On Windows 11: Settings › Bluetooth & devices › Printers & scanners › Add device. On macOS: System Settings › Printers & Scanners › Add Printer.
5. Print a test page and run a scan if this is an all-in-one, so you find any problem now rather than when you are in a hurry.

Ink, toner and supplies

The Brother MFC-L9670CDN uses the following consumables. Match the number exactly when you buy: the same printer family often uses several different cartridge numbers by region.

• TN-810XL high-yield toner set
• TN-815BK/C/M/Y ultra high-yield toner (15,000 / 12,000 pages)
• DR-810CL drum unit
• BU-800CL belt unit
• WT-800CL waste toner box

High-yield (XL) versions almost always cost less per page if you print regularly. On third-party ink and toner, read our honest assessment first, and note that some manufacturers push firmware that rejects non-original chips.
