Our take
Canon's imageCLASS MF455dw is a monochrome all-in-one that prints, copies, scans, sends, and faxes. The U.S. specification lists up to 40 ppm on Letter, standard automatic duplex printing, Wi-Fi, Gigabit Ethernet, USB, and a standard 250-sheet cassette plus 100-sheet multipurpose tray. Its 50-sheet single-pass duplex ADF can scan both sides of an original in one pass. Canon does not publish a recommended monthly print volume in the reviewed specification, so the workload range remains unknown. This makes the MF455dw a capable paper-workflow device, but a buyer who needs a documented monthly range should compare another model.
A small or midsize office needing a networked mono fax MFP that handles two-sided output and original scanning in one pass..
Choose another model if color output, a published recommended monthly volume, or a larger output bin is necessary for the office.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Canon lists print, copy, scan, send, and fax functions for this exact monochrome model.
- Automatic duplex printing and a single-pass duplex ADF handle both sides of output and originals.
- Wi-Fi, Gigabit Ethernet, USB, and a 350-sheet standard input support flexible shared use.
What to weigh up
- The checked Canon material does not give a recommended monthly print range.
- The 65-sheet output capacity is much smaller than the input supply and may need attention during longer jobs.
- The rated 40 ppm speed is a manufacturer specification, not a guarantee for a particular file or used unit.

Full review: how the features affect your choice
What the features mean for you
A mono MFP that includes fax and send functions
Canon lists print, copy, scan, send, and fax as standard functions. That gives a small office a single place to handle black-and-white documents and common communication tasks. The output is monochrome, so this is not suited to color graphics or marked-up pages. If fax is not used, a simpler printer may reduce complexity. The exact MF455dw name should be retained when checking offers because adjacent MF451, MF452, and MF453 models are distinct variants even though Canon groups their user guide.
Duplex output and duplex scanning are separate strengths
The MF455dw has standard automatic duplex printing and a single-pass duplex ADF. Those are distinct functions: the print engine turns output sheets, while the feeder captures both sides of originals in one pass. Canon lists a 50-sheet ADF capacity, making it useful for a stack of two-sided records. Buyers should still check supported original sizes and weights in the manual. This combination is a meaningful difference from a printer with only manual duplex or a simplex feeder, especially when both output and intake are routinely double-sided.
Several interfaces and 350 standard sheets
Canon documents USB, Gigabit Ethernet, Wi-Fi, and Wi-Fi Direct. Standard input combines a 250-sheet cassette with a 100-sheet multipurpose tray. That gives the office both wired and wireless connection choices and space for a second media type, while keeping refill needs visible. The 40 ppm Letter rating provides a published speed reference, but a job's actual pace varies with content and setup. The 65-sheet output capacity is comparatively limited, so a buyer should consider where stacks will collect during longer runs.
Keep monthly capacity unknown
Canon's checked U.S. specification does not provide a recommended monthly print volume for the MF455dw. Its rated speed and maximum pages per month, if found in a separate source, would not fill a recommendation field. The profile therefore leaves both endpoints null. This does not say the printer is unsuitable for a particular routine; it says the reviewed evidence does not support a numerical recommendation. Estimate expected use and compare with a model whose maker provides that guidance if workload planning is central to the decision.
Inspect the exact unit and its connections
The official spec sheet establishes the original feature set but not the state of a particular offer. Confirm the MF455dw label, toner condition, ADF rollers, scanner glass, duplex operation, network setup, firmware, and current driver compatibility. The model uses a 120–127 V supply according to Canon's brochure, which is relevant for deployment. The tagged Amazon destination searches for the exact name because the historical ASIN has not been proven as a current exact match. No current price, inventory, buyer-review consensus, or firsthand test result is claimed.
Compare for your needs
A mono duplex printer is simpler for print-only work, while a color MFP is needed for graphics or color originals.
