Discontinued. The MF249dw was the top of Canon's MF240 series; its replacement MF260 series uses Canon 051 toner, but Canon 137 is still widely sold, including our compatible version.

What imageCLASS MF249dw owners ask

These come from owner reviews of the MF240 series at Best Buy and Amazon, answered in our words.

How is the MF249dw different from the MF247dw?

It was the top of the series: a 50-sheet feeder that scans both sides in one pass, plus NFC tap-to-print. Same 28-page-per-minute engine, fax, duplex printing and 137 toner.

Why does it drop off Wi-Fi?

Usually after sleep. Reserve an IP address on the router or use Ethernet.

Why does it say "non-Canon cartridge" with genuine toner?

Expired cartridges are the usual cause. Reseat and power-cycle; our compatibles carry a fresh chip and are replaced under our 1-year guarantee if refused.

Why are scans pale?

Raise the density setting and scan at 300 dpi; the scanner is adequate for documents, not photos.

Can I still get drivers?

Yes, from Canon's support site; AirPrint and Mopria also work without a driver.

MF249dw quirks worth knowing

The two-sided feeder makes it the only MF240 model that handles double-sided originals in one pass.
Touchscreen, 250-sheet cassette and single-sheet bypass slot.
Canon's MF260 replacements use Canon 051, so 137 spares don't carry over.
