The catch
Canon MF662Cdw
Lacks an automatic document feeder.
Side by side
Canon MF662Cdw vs MF665Cdw: Books still go on the glass, but 665 feeds loose stacks
Quick verdict
Loose document stacks, two-sided originals or fax point to the MF665Cdw. When copying mostly means a book page or a single sheet, the simpler MF662Cdw fits, and both are rated at 26-ppm for color printing.
Before you buy
Why, and what it costs you
Sixty faces to capture come from thirty double-sided pages
The MF665Cdw feeds the 30-sheet packet and scans both sides in one pass. With the MF662Cdw, each face has to be placed on the glass. What this shows is a difference in handling. It is not a measured time saving.
Where this comes from
30 sheets x 2 faces=60. MF 665 has a 50 sheet duplex ADF, MF 662 only a flatbed.
The catch
Canon MF665Cdw
Special media that it supports has to be fed one sheet at a time through the bypass.

- Why pick it

Canon MF665Cdw
- Why pick it
- Double-sided paperwork needs scanning
- Fax matters to you, or so does scanning loose sheets unattended
- The catch
- Special media that it supports has to be fed one sheet at a time through the bypass.

In practice
Differences you will notice
Sixty faces to capture come from thirty double-sided pages
The MF665Cdw feeds the 30-sheet packet and scans both sides in one pass. With the MF662Cdw, each face has to be placed on the glass. What this shows is a difference in handling. It is not a measured time saving.
How we worked this out
30 sheets x 2 faces=60. MF 665 has a 50 sheet duplex ADF, MF 662 only a flatbed.
The feature you are paying extra for goes unused on a book
Books fit on the flatbed of either. The MF665Cdw feeder helps with separate supported sheets, which means the upgrade gains less for someone copying bound material than for someone processing forms.
How we worked this out
Each platen accepts Sheet, Book. An ADF is on MF 665 alone.
On the headline specs that count, color printing ends in a tie
Each is rated 26 Letter ppm and has a 250-sheet cassette with a one-sheet feed. The reasons to buy the 665 are its document intake and fax. It does not print handouts any faster.
How we worked this out
Print speed and paper input shared, per the manufacturer.

Spec by spec
Where they really differ
| Spec | Canon MF662Cdw | Canon MF665Cdw | In practice |
|---|---|---|---|
| Scanner feed | Flatbed only | 50-sheet single-pass duplex ADF plus flatbed | Pick the 665 if your work involves loose stacks. |
| Fax | No | Yes | Telephone-line fax as a requirement points to the 665. |
| Letter color output | Up to 26 ppm | Up to 26 ppm | Adding the scanner brings no faster print engine. |
| Standard paper input | 250-sheet cassette plus one-sheet feed | 250-sheet cassette plus one-sheet feed | Capacity for ordinary printing is unchanged. |
Trade-offs
What each pick costs you
With Canon MF662Cdw
- Supported special media has to be loaded sheet by sheet through its one-sheet manual feed.
With Canon MF665Cdw
- Canon’s published recommended range is exceeded by recurring workloads above 2,500 pages a month.
Change of plan
When the answer changes
Loose multipage packets are part of your regular scanning
Go with Canon MF665Cdw. The ADF spares you repeated flatbed placement.
All you copy are the odd bound or single-page originals
Go with Canon MF662Cdw. This work is already covered by the flatbed.
A thick stack of envelopes has to be loaded and left unattended
Neither model fits. A one-sheet multipurpose feed is on each. Confirm the media restrictions in the manual.
Decision guide
How to decide
The MF665Cdw is the one for fax, two-sided originals or stacks of loose documents. Copying a book page or single sheet is simple enough for the MF662Cdw, and the pair share a 26-ppm rated color print speed.
Look first at the paper that lands on your desk
Signed forms arriving in a packet are where the 665 earns its place. One book page a week does not create that need. Since both printers can output two-sided color documents, what matters is how paper gets into the scanner.
Single-pass scanning solves one particular problem
A 50-sheet single-pass feeder is built into the 665, and it reads both faces of supported originals so you do not have to flip the stack. Mixed front-and-back paperwork is where that counts, since a missed reverse page there would cost you.
A fax modem is not an online fax service
Fax is something the 665 adds. Before you build a purchase around it, check what connection it requires and what your telephone service provides. Scanning to files on the 662 is not the same as having fax hardware.
Different paper types still take careful handling
A 250-sheet cassette and a one-sheet bypass are common to both. Upgrading the scanner does not make the 665 a bulk special-media printer, so match size, weight and supported media to the tray you will use.
What this page can’t tell you
- No matched hands-on tests sit behind the rated print speeds. They are manufacturer figures.
- Toner yields are tied to standardized test documents and shift with what you print.
