Discontinued. The MF212w (2015) was replaced by the MF232w and then the MF260 series; Canon 137 is still widely sold, including our compatible version.

What imageCLASS MF212w owners ask

These come from 425 owner reviews at Best Buy, answered in our words.

Why does it drop off Wi-Fi every day?

The most common complaint: it loses the router when the DHCP lease renews. Reserve a fixed IP address for the printer on the router; the MF212w has no Ethernet port, so that or USB are the only fixes.

Does it print two-sided?

No, and it has no document feeder. The MF244dw adds both with the same toner.

Is setup hard?

Owners are split; those who followed the manual's WPS steps report a painless setup, and Canon's phone support gets repeated praise.

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.

Is there a toner-saving mode?

One reviewer notes none in the printer settings; the driver's draft/toner-saver option does the job from the computer.

MF212w quirks worth knowing

24 pages a minute with a 250-sheet cassette, unusually large for an entry model.
It's louder than later models; noise is the second most-mentioned con.
Canon's MF260 replacements use 051 toner, so 137 spares don't carry over.
