Head-to-head
Canon MF662Cdw vs MF665Cdw: 665 feeds loose stacks, books still need the glass
The short answer

Before you choose
The reasoning and the trade-offs
Thirty double-sided pages mean sixty faces to capture
The MF665Cdw can feed the 30-sheet packet and scan both sides in one pass. On the MF662Cdw, every face needs placement on the glass. This is a handling difference, not a measured time saving.
What this is based on
30 sheets x 2 faces=60. MF 665 50 sheet duplex ADF. MF 662 flatbed only.

What matters in practice
The differences that matter
Thirty double-sided pages mean sixty faces to capture
The MF665Cdw can feed the 30-sheet packet and scan both sides in one pass. On the MF662Cdw, every face needs placement on the glass. This is a handling difference, not a measured time saving.
How we reached this conclusion
30 sheets x 2 faces=60. MF 665 50 sheet duplex ADF. MF 662 flatbed only.
A book does not use the feature you are paying extra for
Both have a flatbed that accepts books. The MF665Cdw feeder helps with separate supported sheets, so someone copying bound material gains less from the upgrade than someone processing forms.
How we reached this conclusion
Both platen accepts Sheet, Book. Only MF 665 has ADF.
Color printing is a tie on the useful headline specs
Both are rated 26 Letter ppm and have a 250-sheet cassette with a one-sheet feed. Buy the 665 for its document intake and fax, rather than expecting faster printed handouts.
How we reached this conclusion
Shared manufacturer print speed and paper input.

What changes the fit
| What changes | Canon MF662Cdw | Canon MF665Cdw | Why it matters |
|---|---|---|---|
| Scanner feed | Flatbed only | 50-sheet single-pass duplex ADF plus flatbed | Loose stacks are the reason to choose the 665. |

What you give up
Every choice has a cost
If you choose Canon MF662Cdw
- Its one-sheet manual feed requires individual loading for supported special media.
If you choose Canon MF665Cdw
- Recurring workloads above 2,500 pages a month exceed Canon’s published recommended range.
Recommendation switch
The decision flips if...
Your regular scanning involves loose multipage packets
Choose Canon MF665Cdw. The ADF removes repeated flatbed placement.
You only copy occasional bound or single-page originals
Choose Canon MF662Cdw. The flatbed already covers this work.
You need to load a thick envelope stack unattended
Choose neither. Both have a one-sheet multipurpose feed. Confirm the manual media restrictions.
What matters in practice
How to make the call
Start with the paper arriving at your desk
A packet of signed forms makes the 665 valuable. A book page once a week does not create the same need. Both printers can produce two-sided color documents, so concentrate on how you get paper into the scanner.
Single-pass scanning is a specific convenience
The 665 has a 50-sheet single-pass feeder. It scans both faces of supported originals without sending you back to flip the stack. That capability matters for mixed front-and-back paperwork where missing a reverse page would be costly.
Do not confuse a fax modem with online fax services
The 665 adds a fax function. Check the required connection and your telephone service before buying around it. The 662 can scan to files, but that alone is not the same thing as having the fax hardware.
Paper variety still needs individual care
Both have a 250-sheet cassette and a one-sheet bypass. The scanner upgrade does not turn the 665 into a bulk special-media printer. Check size, weight and supported media against the actual tray you plan to use.
What this comparison cannot tell you
- Rated print speeds are manufacturer figures, not matched hands-on tests.
- Toner yields use standardized test documents and vary with content.
