Canon imageCLASS MF665Cdw: Setup, Drivers, Ink and Common Problems

Is the Canon imageCLASS MF665Cdw right for you?

The MF665Cdw headlines the five-model colour laser line Canon announced in September 2025 for home and small offices, replacing the MF656Cdw as the fax-equipped touchscreen colour MFP. Canon pitched the family on faster first-page times and stronger security for hybrid workers. As a brand-new model, toner part numbers and real-world reliability are not yet well documented, so treat the details here as provisional.

Setting up the Canon imageCLASS MF665Cdw

Connect Ethernet or use the touchscreen Wi-Fi wizard, then install the current MF660C series package from Canon USA for scanning and faxing. Set an administrator password during first boot and run colour calibration after installing the starter toners. Check the toner label inside the front door before ordering replacements.

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 Canon'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 Canon imageCLASS MF665Cdw uses the following consumables. Match the number exactly when you buy: the same printer family often uses several different cartridge numbers by region.

• Canon genuine toner cartridges for the MF660C series (confirm the cartridge number on the toner label)

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.
