Canon Color imageCLASS MF665Cdw Review – Reliable All-in-One Laser

Quick Verdict

The Canon Color imageCLASS MF665Cdw is a capable mid-range all-in-one color laser printer that covers the basics — and then some — for small offices and workgroups. After three weeks of real-world use, I can say the 26 ppm print speed, duplex ADF, and 5-inch touchscreen genuinely earn their keep. It's not the cheapest option in its class, and the toner running costs deserve a hard look before you commit. But for a reliable, self-contained wireless printing hub that doesn't need hand-holding every time a deadline hits? It mostly delivers. I'd score this around 4.3 out of 5 for most office environments.

What Is the Canon Color imageCLASS MF665Cdw?

Let's cut to the chase: the Canon Color imageCLASS MF665Cdw is a color laser all-in-one built for offices that need to print, scan, copy, and fax without juggling four separate machines. It sits in the mid-tier of Canon's imageCLASS lineup, offering wireless connectivity, automatic duplexing, and a document feeder that handles two-sided originals in a single pass. The spec sheet lists 26 pages per minute in both color and monochrome, which on paper sounds plenty fast enough for a five-to-ten-person team.

I unboxed ours on a Monday morning — rain tapping the window, coffee getting cold on my desk. The setup wizard on the 5-inch color touchscreen walked me through Wi-Fi in about twelve minutes, which is faster than I expected from a Canon product out of the box. By 9:15 I had my first test page rolling, and by 10:00 the ADF had chewed through a 30-page contract without a single jam. That early reliability set the tone for the rest of the review period.

Hands-On Review

After the first week, the Canon MF665Cdw had settled into a rhythm on my desk — print jobs came through from two laptops, a work tablet, and occasionally my phone when I was too lazy to walk back from the conference room. The wireless connection held steady even when the office Wi-Fi was congested, which isn't something I can say about every printer I've tested.

What surprised me was the print quality on the color output. Marketing material for color lasers often oversells vibrancy, but the MF665Cdw genuinely produces punchy, readable charts and client-facing graphics. I printed a batch of proposal covers with our company logo, and the deep red and navy looked consistent from page one to page fifty — no noticeable drift or banding. That steadiness matters when you're sending documents out the door.

The duplex ADF is where this printer earns its keep in a busy office. I ran a 22-page legal addendum through it on a Thursday afternoon, and the one-pass double-sided scan took under two minutes total. That's the kind of throughput that keeps a small team from bottlenecking at the scanner. By contrast, the single-sheet multipurpose tray irritated me every time I needed to feed an envelope or a half-sheet insert — there's no bypass tray beyond that one slot, so you're pulling the main cassette for anything outside of letter/A4.

Noise is worth mentioning. The MF665Cdw isn't loud during normal print runs, but the cooling fan cycles on after heavier jobs and runs for a good thirty seconds. In an open-plan office, that hum registers. It's not a dealbreaker, but it's the kind of thing nobody mentions in the product listings. I also noticed the toner cost adds up faster than I initially estimated — the high-capacity Toner 075 cartridges last longer than standard, but the per-page cost still skews higher than comparable inkjet systems if you're printing thousands of pages per month.

Who Should Buy It?

The Canon Color imageCLASS MF665Cdw makes the most sense for small offices and workgroups — typically five to fifteen people — who need reliable color output without a dedicated IT staff. If your team prints client-facing proposals, contracts with color highlights, or marketing one-pagers on a regular basis, the color laser engine justifies the upfront cost over a monochrome unit.

Home offices with multiple connected devices will appreciate the wireless simplicity and mobile printing support. The touchscreen is intuitive enough that non-technical users can navigate it without a manual.

Legal practices, real estate offices, and consulting firms that regularly process two-sided contracts and multi-page packets will get the most value from the duplex ADF. The one-pass scanning genuinely saves time when you're handling originals daily.

Skip this printer if your print volume is minimal — a few pages a week — and you mostly work in black and white. An entry-level monochrome laser or a well-reviewed inkjet will cost you significantly less over time in consumables. Also skip it if you're hoping for glossy photo output; this is a business laser, not a photo printer, and the toner isn't formulated for that.

Alternatives Worth Considering

If the Canon Color imageCLASS MF665Cdw feels like more printer than you need, the HP Color LaserJet Pro MFP M479fdw is a direct competitor with a comparable feature set. HP's interface leans slightly more toward enterprise IT management, which some offices prefer. The Canon edges it out on touchscreen usability in my experience.

The Brother MFC-L8900CDW is another strong alternative, particularly if your office already runs Brother equipment and values the lower cost-per-page on high-yield toner. The Brother ecosystem has a slightly steeper learning curve for initial setup, but the ongoing operational costs can be kinder to your budget at high volumes.

For tighter budgets where color laser isn't strictly necessary, the monochrome-only Canon imageCLASS DANCE LBP236dw delivers faster single-sided speeds and a lower price point, though you lose the scanner, copier, and fax entirely.

FAQ

Final Verdict

The Canon Color imageCLASS MF665Cdw is a solid mid-range choice for offices that need a dependable all-in-one color laser without enterprise-level complexity. The 26 ppm engine, duplex ADF, and wireless stack work as advertised — and the 5-inch touchscreen is genuinely pleasant to use compared to the cramped button clusters on older Canons. Toner cost remains the biggest ongoing concern, and the limited multipurpose tray is a frustration worth knowing about before you buy. For what it is — a self-contained, low-fuss color printing hub — it does the job well enough that I'd recommend it to most small-office buyers.
