Head-to-head
Canon R40 II vs ScanSnap iX2400: iX2400 holds more paper with less open-tray depth
The short answer
Choose the iX2400 for large loose-paper batches and a shorter open-tray depth. Choose the R40 II when its TWAIN route fits your existing Windows software and a 60-sheet feeder is enough.
Before you choose
The reasoning and the trade-offs
The forty-five-ppm headline does not mean the same color job
Canon rates the R40 II at 45 ppm for grayscale at 300 dpi, but color at 300 dpi falls to 40 ppm. The iX2400 remains rated at 45 ppm for A4 color at 300 dpi. For color originals, compare those mode-specific figures rather than the two headline numbers.
What this is based on
Both are manufacturer ratings. Image processing, computer performance and saving time remain outside this comparison.
Main trade-off
Ricoh ScanSnap iX2400
No Wi-Fi or touchscreen for choosing destinations at the scanner.

About this comparison
Compare color-mode speed, open-tray depth and 60- versus 100-sheet feeding. The right USB scanner depends on your software and typical packet.
Choose the iX2400 for large loose-paper batches and a shorter open-tray depth. Choose the R40 II when its TWAIN route fits your existing Windows software and a 60-sheet feeder is enough.

What matters in practice
The differences that matter
The forty-five-ppm headline does not mean the same color job
Canon rates the R40 II at 45 ppm for grayscale at 300 dpi, but color at 300 dpi falls to 40 ppm. The iX2400 remains rated at 45 ppm for A4 color at 300 dpi. For color originals, compare those mode-specific figures rather than the two headline numbers.
How we reached this conclusion
Both are manufacturer ratings. Image processing, computer performance and saving time remain outside this comparison.
A shallow working desk can favor the bigger feeder
Despite holding more sheets, the iX2400 lists an operating depth of 18.78 inches versus 23.1 inches for the R40 II. That is 4.32 inches less front-to-back room. You still need the stated access and cable allowances, but feeder size alone does not predict desk fit.
How we reached this conclusion
23.1 minus 18.78 equals 4.32 inches. Both values describe expanded operating dimensions rather than closed storage dimensions.
A ninety-sheet folder and an existing app can point opposite ways
Ninety ordinary sheets fit once in the iX2400 but need two loads in the R40 II. If your software requires TWAIN, however, the Canon's application route may be more important than avoiding that reload. ScanSnap would require its own capture step followed by importing the file.
How we reached this conclusion
Confirm the exact application and OS. A supported file export is different from direct acquisition inside an existing program. Canon's 60-sheet rating applies to A4 or smaller at 80 gsm. Larger sheets reduce its stated capacity to 50.

Meaningful differences
What changes the fit
| What changes | Canon imageFORMULA R40 II | Ricoh ScanSnap iX2400 | Why it matters |
|---|---|---|---|
| Feeder | 60 A4 sheets at 80 gsm, 50 above A4 | 100 sheets | The ScanSnap avoids a reload for packets between 61 and 100 sheets. |
| Color at 300 dpi | 40 ppm and 80 ipm | 45 ppm and 90 ipm | Canon's 45 ppm headline applies to other modes. |
| Operating depth | 23.1 inches | 18.78 inches | The ScanSnap needs 4.32 fewer inches of open-tray depth. |
| Application driver | TWAIN route | ScanSnap-specific, no TWAIN | Existing software can reverse the feeder-based recommendation. |
| Power | AC adapter with USB data | AC adapter with USB data | Neither is powered solely by the USB-C data connector. |
What you give up
Every choice has a cost
If you choose Canon imageFORMULA R40 II
- It needs an AC adapter, and color scanning at 300 dpi is rated at 40 ppm rather than 45 ppm.
If you choose Ricoh ScanSnap iX2400
- It does not provide TWAIN support for an existing capture application.
Recommendation switch
The decision flips if...
You regularly exceed 60 sheets and can use ScanSnap Home
Choose Ricoh ScanSnap iX2400. The 100-sheet feeder removes a refill.
TWAIN acquisition is essential to your current application
Choose Canon imageFORMULA R40 II. The Canon supports that route.
You need phone-only scanning without a computer connection
Choose neither. Both compared configurations are USB host workflows without Wi-Fi.
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.
