Our take
The imageCLASS MF424dw stands out as a monochrome document MFP that handles two-sided output and duplex originals. Canon rates it up to 40 pages per minute and specifies a 50-sheet duplex ADF that scans both sides in one pass. Wi-Fi, Ethernet, and USB provide flexible connections, while 350 sheets of standard input and a recommended monthly range of 500–4,000 pages define its workgroup scale. It is a strong fit for paper-heavy black-and-white workflows that need fax and scanning without color.
An office that processes two-sided originals and wants both wired and wireless connections in a mono MFP..
Choose another model if color is required, if the regular workload exceeds 4,000 recommended pages monthly, or if a larger standard paper reserve is needed.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Canon documents print, copy, scan, and fax with automatic duplex printing.
- The 50-sheet duplex ADF scans both sides in one pass.
- Wi-Fi, Ethernet, and USB provide multiple documented connection choices.
What to weigh up
- Output is monochrome only.
- The 250-sheet cassette plus 100-sheet bypass provide 350 sheets of standard input.
- A 40 ppm rating is a manufacturer specification, not a guaranteed pace for every job.

Full review: how the features affect your choice
What the features mean for you
A mono MFP for the full paper cycle
Canon's U.S. support record identifies the MF424dw as a monochrome laser multifunction model for print, copy, scan, send, and fax tasks. This mix is useful in an office where paper documents arrive from several directions and staff need to return them as digital files or faxes. It does not provide color, so presentations and color markup belong on another device. The exact dw model designation matters for its wireless and duplex capabilities; do not transfer those features from a nearby imageCLASS product without confirming the full model name.
Rated output and duplex support reports
Canon rates printing up to 40 pages per minute and documents automatic duplex output. That pairing suits recurring mono reports because the printer can turn each page while maintaining a substantial rated pace. Actual completion time varies by file and job handling, so the rating is a comparison point rather than a promise. Two-sided output can reduce manual handling for multi-page documents. A buyer with primarily single-page jobs may place more value on the fax and scanning functions than on duplex, while a report-heavy team can use both features regularly.
A duplex ADF changes scanning work
The MF424dw has a 50-sheet duplex automatic document feeder that Canon describes as single-pass duplex scanning. This can streamline packets with information on both sides of each sheet by avoiding a second manual pass. The feeder still holds a finite stack, so large archives need to be divided into loads. It also matters that duplex scanning is separate from duplex printing: this model documents both. If the main workload is digitizing two-sided originals, that combination is more important than a generic all-in-one label.
Use the two paper inputs deliberately
Canon specifies a 250-sheet cassette and a 100-sheet bypass, for 350 sheets of standard input. The cassette can hold the everyday paper, and the bypass can be useful when a job uses another stock or size. This is a moderate reserve for a shared office and means larger queues require periodic replenishment. The figures describe the model's standard input, not supplies or accessories currently present in a used offer. Check tray condition and confirm that paper sizes needed for the office are compatible with the exact setup.
Choose the connection that fits the office
Canon documents Wi-Fi, Ethernet, and USB. Wi-Fi allows more flexible placement, while Ethernet supports a fixed shared-network connection and USB a direct workstation. That range is useful when an MFP must serve people across a small office, but the intended network still needs to be configured and tested. Confirm the exact offered model is MF424dw and that its ports and wireless functions work. A manufacturer's interface list cannot establish the configuration, security state, or driver compatibility of an individual machine.
The 500–4,000 page range is a selection aid
Canon recommends monthly use from 500 to 4,000 pages. This documented range gives a buyer a way to compare ordinary office usage with the maker's intended workload. It is not a statement about toner cost, unit condition, or maximum duty cycle. Consider routine monthly output and the number of two-sided documents the office processes, then weigh the feeder and tray capacities against how often someone can replenish them. If fax and duplex scanning are not needed, a simpler printer may be easier to maintain; if color is required, this mono model is the wrong output type.
Compare for your needs
Compare a color MFP if color output is a hard requirement, or a print-only model if document capture and fax are unnecessary.
