Our take
The Canon Color imageCLASS MF644Cdw is a color laser MFP for a small office that needs more than print output. Canon identifies item 3102C005 and lists print, copy, scan, fax, and send functions. The printer is rated up to 22 pages per minute on Letter, with standard automatic duplex. Its 50-sheet ADF scans both sides in one pass, and its connections include Wi-Fi and Gigabit Ethernet. The recommended monthly range is 150–2,500 pages. That combination makes the model unusually complete at a desk, but the modest paper reserve and moderate recommended ceiling are meaningful limits for a larger queue.
A small office that needs color, fax, and duplex document intake as well as automatic two-sided printing, and expects a moderate monthly volume..
Choose another model if your team routinely exceeds Canon's 2,500-page monthly recommendation, needs a high-capacity paper system, or only wants an inexpensive print-only device.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Canon lists print, copy, scan, fax, and send functions, so one machine covers several office document tasks.
- The 50-sheet feeder scans two sides in one pass, reducing manual handling for double-sided originals.
- Wi-Fi and Gigabit Ethernet provide distinct wireless and wired network paths, alongside USB.
What to weigh up
- The recommended monthly range ends at 2,500 pages, below the guidance on heavier workgroup printers.
- The standard 250-sheet cassette and one-sheet bypass are a small reserve for a shared office with frequent replenishment needs.
- Canon's product page establishes original capability, not the present condition, supplies, or seller terms of any used or renewed unit.

What the features mean for you
Do you need all five office functions?
Canon lists printing, copying, scanning, fax, and send for the exact MF644Cdw. That matters when employees move between paper originals, digital files, and outgoing fax work during the day. Its color engine can handle graphics and color-coded documents as well as black text. A print-only unit may be simpler if those extra functions sit unused, but this model has a clear role when the office wants one shared device for mixed paper workflows. Fax and network scanning still depend on the office's own line and setup.
What does one-pass duplex scanning change?
The 50-sheet ADF is specified as a single-pass duplex feeder, so it captures both sides of an original as sheets move through once. This can save handling for contracts, forms, and packets with printing on both sides. It is distinct from automatic duplex output: the printer also turns sheets automatically when creating two-sided prints. Check whether the ADF's stated sheet capacity covers your typical batch and confirm that the specific used device includes its feeder assembly. Canon documents capacity, not the condition of an offered machine.
Will its speed and monthly guidance fit?
Canon rates the MF644Cdw up to 22 ppm on Letter and recommends 150–2,500 pages per month. The speed is a manufacturer maximum under defined conditions, not a guarantee for every file or connected computer. The monthly range is the better workload comparison point; it should not be confused with the higher duty-cycle ceiling. This model suits a moderate queue where color and scanning matter more than high-volume throughput. If your actual pages regularly approach or exceed the range, compare an enterprise printer with a higher recommendation and larger paper reserve.
Which connection matches the room?
Canon lists Wi-Fi 802.11b/g/n, Wi-Fi Direct, Gigabit Ethernet, and USB. Wi-Fi can place the unit without a network cable at the device; Ethernet offers a wired shared connection; USB serves a directly attached computer. These options are not interchangeable in every office, especially where a network policy requires wired access or where the printer will be away from an access point. Confirm the intended print, scan, and fax paths with the devices and network you use. A specification cannot establish that a used port or radio is still working.
How much paper will the standard tray hold?
The standard cassette holds 250 sheets and the bypass accepts one sheet. That setup can cover ordinary desk and small-office printing, with the bypass available for a one-off envelope or alternate sheet. It does not provide a deep paper reserve or multiple standard drawers for keeping different stocks loaded. In a shared environment, refill frequency and media changes may matter as much as rated speed. Think through whether people will print mostly from one tray and whether you can accept loading special media individually before choosing this all-in-one.
What else to compare
For a higher monthly workload, compare a workgroup color MFP with a larger standard tray and higher published recommendation. If you do not need fax or duplex scanning, a simpler color printer may be easier to place and maintain.
Before you buy
Does the MF644Cdw fax?
Yes. Canon lists fax among the MF644Cdw's core functions, along with print, copy, scan, and send.
Can its document feeder scan both sides in one pass?
Yes. Canon specifies a 50-sheet single-pass duplex ADF, which captures both sides during one feeder pass.
What is Canon's recommended monthly range?
Canon lists a recommended range of 150–2,500 pages per month; its separate duty-cycle maximum is not a routine target.

The decision
The MF644Cdw is a versatile moderate-volume color MFP whose fax and one-pass duplex ADF distinguish it from simpler models. Its 2,500-page recommended ceiling and limited standard paper capacity define the trade-off.
