Our take
The Canon imageCLASS MF426dw is a monochrome fax MFP with a stronger office workflow than a basic all-in-one: Canon rates it up to 40 pages per minute on Letter paper, recommends 500 to 4,000 pages per month and includes automatic duplex printing. Its 50-sheet single-pass duplex ADF reads both sides of an original in one pass, while Wi-Fi and Gigabit Ethernet cover wireless and wired installations. This mix fits a small or medium office with regular paper capture and a shared queue. The standard tray capacity is useful but modest beside models designed for larger uninterrupted runs.
A small or medium monochrome office that needs fax, duplex capture and both wireless and wired networking..
It is not a color printer and may not suit a heavy department that needs more than 900 sheets of configured input or a larger output bin.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Canon specifies 40 ppm Letter output and a 500–4,000 page recommended monthly range.
- The 50-sheet single-pass duplex ADF handles both sides of originals, alongside automatic duplex printing.
- Wi-Fi, Wi-Fi Direct and Gigabit Ethernet provide flexible network placement.
What to weigh up
- Standard input is 350 sheets and standard output is 65 sheets, so longer jobs can require more frequent attention.
- Optional feeders increase paper capacity but add size and are not guaranteed to be present in a used offer.
- The monochrome engine cannot produce color pages, despite the color-capable scanner.

What the features mean for you
The workload guidance points to regular small-office use
Canon recommends 500 to 4,000 pages each month and rates the MF426dw for up to 40 pages per minute on Letter paper. These figures describe model-level guidance and rated output, not a performance promise for an older individual printer. They are useful when deciding whether a personal desktop model is too small or an enterprise floor device is unnecessary. The MF426dw adds copy, scan and fax functions for an office that handles paper throughout the day. If your work needs color output, this monochrome engine is the wrong tool even though its scanner captures color originals.
A duplex feeder saves time on both sides of a document
Canon lists a 50-sheet single-pass duplexing ADF, which reads both faces of an original in one feeder pass. It also documents automatic two-sided printing. Those functions work together for a paperwork routine that includes receiving duplex forms, scanning them and printing copies or new reports without manual page flipping. A small office can keep a file capture workflow moving without scanning the first side and then reversing the stack. Check feeder rollers and scan glass on a used device, because model specifications cannot tell you whether a particular ADF is clean or feeds evenly today.
Wired and wireless networking support a shared queue
The specification sheet lists Gigabit Ethernet and Wi-Fi 802.11b/g/n as standard, along with Wi-Fi Direct, USB and USB host ports. A site can choose a fixed network cable for a managed office or wireless placement where the printer does not sit beside an Ethernet jack. The 5-inch color touch panel provides local access to the device's multifunction controls. Verify the network security policy and driver compatibility before deployment. A printer can have the right port and still need configuration work, and the source does not establish the saved settings on a seller's unit.
Standard input is expandable but not unlimited
The base configuration holds 350 sheets: a 250-sheet cassette and a 100-sheet stack bypass. Canon lists 900 sheets maximum with optional cassettes, while output capacity is 65 sheets. That makes the standard device suitable for a regular small-office queue, but not a set-it-and-forget-it high-volume production station. Optional paper feeders occupy extra space and need to be confirmed on the specific machine. Consider the size of your normal run and how often someone can refill the cassette. For envelopes, thicker stock or one-off media, the bypass tray gives a separate path from the everyday paper supply.
Confirm the exact model and condition before relying on it
Canon documents fax, a 50-sheet duplex ADF, a 5-inch touchscreen and multiple network interfaces for the MF426dw. Those features make it useful but also create more components to inspect: the feeder, scanner glass, fax connection, Wi-Fi radio, Ethernet port and optional cassette. Canon's page confirms specifications for the model, not the present toner level, maintenance history or warranty on a specific used listing. Check the model label and the operating systems in use before buying. An Amazon model search carries the required referral tag and helps find listings, but it does not establish current availability or the accuracy of seller claims.
What else to compare
Compare the Canon MF525dw for a higher 2,000–7,500 page monthly recommendation and 650-sheet standard input, or Brother MFC-L2690DW for a compact Wi-Fi-only home-office role.

The decision
The MF426dw suits a small workgroup that needs fast monochrome printing, fax, duplex document capture and both common network paths. Its standard paper stack remains the practical limit.
