Canon imageCLASS MF249dw: Setup, Drivers, Ink and Common Problems

Is the Canon imageCLASS MF249dw right for you?

The MF249dw was the complete version of the MF240 family, with fax and NFC added to the ADF, duplex and Ethernet of the MF244dw. It was popular with accountants and medical offices that still fax, and the 2,400-page Cartridge 137 kept costs sensible. Like its siblings it is now discontinued, but drivers remain available and the hardware is durable enough that many are still in daily use.

Best for: Offices that still need laser fax with ADF and duplex

Setting up the Canon imageCLASS MF249dw

Connect Ethernet or pick a 2.4 GHz network from the LCD, plug in the phone line and run the fax setup guide for your number and receive mode. Install the full MF240 package for scanning and PC faxing. Tap an NFC-enabled Android phone on the panel with Canon PRINT Business installed to print directly.

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 MF249dw uses the following consumables. Match the number exactly when you buy: the same printer family often uses several different cartridge numbers by region.

• Cartridge 137

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.
