Head-to-head
Canon RS40 vs Epson FF-680W: Epson shares photos wirelessly and feeds more documents
The short answer
Choose the FF-680W when the same machine must handle larger document batches and wireless photo sharing. Choose the RS40 for a fixed USB photo station when its 40-photo batch and CaptureOnTouch workflow suit your archive.
Before you choose
The reasoning and the trade-offs
More photos per load does not mean more documents per load
Canon lists 40 photos and 60 paper sheets. Epson lists 36 photos below 0.23 mm and 100 sheets of 80 gsm paper. A household archiving both loose prints and old paperwork can therefore prefer Canon's photo capacity but Epson's document capacity.
What this is based on
Do not mix the capacity units. Epson's marketing rounds its photo batch to 35, while the technical table gives 36 with a thickness condition.
Main trade-off
Epson FastFoto FF-680W
Photo capacity depends on thickness, and damaged or unsuitable originals need special handling.

About this comparison
Compare photo batches, handwritten backs and ordinary paperwork. Wireless placement and document capacity can matter more than a photo-speed headline.

What matters in practice
The differences that matter
More photos per load does not mean more documents per load
Canon lists 40 photos and 60 paper sheets. Epson lists 36 photos below 0.23 mm and 100 sheets of 80 gsm paper. A household archiving both loose prints and old paperwork can therefore prefer Canon's photo capacity but Epson's document capacity.
How we reached this conclusion
Do not mix the capacity units. Epson's marketing rounds its photo batch to 35, while the technical table gives 36 with a thickness condition.
The notes on the back may matter more than the print alone
Both have single-pass duplex capture, which helps retain dates or names on the back of suitable loose prints. Epson adds an app workflow for voice and text stories. That can be useful while a relative can still explain the scene, but it does not replace checking each saved image and annotation.
How we reached this conclusion
Scan both faces when the reverse carries information. Neither machine should receive a bound album or unsuitable damaged print.
Six-hundred-dpi optics should not be confused with enlargement output
Both specify 600 dpi optics and can produce 1200 dpi interpolated output. A larger output file does not establish twice the captured optical detail. For fragile or irreplaceable prints that do not meet feeder rules, investigate a flatbed workflow.
How we reached this conclusion
No matched image-quality or restoration test was performed. Follow each manufacturer's accepted-media rules.

Meaningful differences
What changes the fit
| What changes | Canon imageFORMULA RS40 | Epson FastFoto FF-680W | Why it matters |
|---|---|---|---|
| Paper-sheet capacity | 60 sheets | 100 sheets at 80 gsm | A mixed photo-and-paper archive may be limited by document capacity. |
| Photo batch specification | Up to 40 photos | 36 photos below 0.23 mm, marketing says 35 | Photo thickness and preparation affect usable batch size. |
| Connection | USB | USB and Wi-Fi | Epson can be placed without a USB cable to the receiving host. |
| Photo story tools | CaptureOnTouch photo corrections | FastFoto app supports voice and text additions | Epson can preserve explanations as well as the scanned image. |
| Optical resolution | 600 dpi | 600 dpi | 1200 dpi output claims on both do not mean 1200 dpi optics. |
What you give up
Every choice has a cost
If you choose Canon imageFORMULA RS40
- 1200 dpi output is interpolated, and the feeder is not for bound albums.
If you choose Epson FastFoto FF-680W
- Its 1200 dpi photo mode is interpolated rather than 1200 dpi optics.
Recommendation switch
The decision flips if...
Large document batches and wireless placement are regular needs
Choose Epson FastFoto FF-680W. The FF-680W adds 100-sheet paper capacity and Wi-Fi.
One USB photo station and Canon's software cover your job
Choose Canon imageFORMULA RS40. The RS40 can be sufficient without paying for wireless workflow.
The photographs are still glued into an album
Choose neither. Keep the album intact and use a flatbed or overhead scanner.
What matters in practice
Before you choose
What this comparison cannot tell you
- Manufacturer feed ratings do not include document preparation, OCR or saving time.
- Confirm the supported media, scan mode, current operating system and destination before purchase.
