The catch
Canon imageFORMULA R40 II
With the trays extended, it opens out to 23.1 inches deep.
Side by side
Canon R40 II vs ScanSnap iX2400: iX2400 takes more paper and opens its tray less deeply
Quick verdict
Large loose-paper batches and a shorter open-tray depth favor the iX2400. The R40 II is the better fit when its TWAIN route works with your existing Windows software and a 60-sheet feeder is enough.
Before you buy
Why, and what it costs you
The forty-five-ppm headline isn't the same color job on both
For grayscale at 300 dpi, Canon rates the R40 II at 45 ppm, yet color at 300 dpi drops to 40 ppm. The iX2400 keeps its 45 ppm rating for A4 color at 300 dpi. With color originals, compare those mode-specific figures and not the two headline numbers.
Where this comes from
These are manufacturer ratings in both cases. Image processing, computer performance and saving time are not part of this comparison.
The catch
Ricoh ScanSnap iX2400
You can't choose destinations at the scanner, since it has no Wi-Fi or touchscreen.

In practice
Differences you will notice
The forty-five-ppm headline isn't the same color job on both
For grayscale at 300 dpi, Canon rates the R40 II at 45 ppm, yet color at 300 dpi drops to 40 ppm. The iX2400 keeps its 45 ppm rating for A4 color at 300 dpi. With color originals, compare those mode-specific figures and not the two headline numbers.
How we worked this out
These are manufacturer ratings in both cases. Image processing, computer performance and saving time are not part of this comparison.
On a shallow desk, the bigger feeder can win
The iX2400 holds more sheets, yet its listed operating depth is 18.78 inches against 23.1 inches for the R40 II. That saves 4.32 inches of front-to-back room. The stated access and cable allowances still apply, and feeder size by itself does not predict how well it fits a desk.
How we worked this out
23.1 minus 18.78 gives 4.32 inches. Both values are expanded operating dimensions and not closed storage dimensions.
A ninety-sheet folder and an existing app can pull in opposite directions
Ninety ordinary sheets go into the iX2400 in a single load but take two loads in the R40 II. If your software requires TWAIN, though, the application route of the Canon may matter more than skipping that reload. ScanSnap would need its own capture step, followed by importing the file.
How we worked this out
Confirm the exact application and OS. Exporting a supported file is not the same as acquiring directly inside an existing program. Canon’s 60-sheet rating is for A4 or smaller at 80 gsm, and larger sheets bring its stated capacity down to 50.

Spec by spec
Where they really differ
| Spec | Canon imageFORMULA R40 II | Ricoh ScanSnap iX2400 | In practice |
|---|---|---|---|
| Feeder | 60 A4 sheets at 80 gsm, 50 above A4 | 100 sheets | For packets of 61 to 100 sheets, the ScanSnap saves you a reload. |
| Color at 300 dpi | 40 ppm and 80 ipm | 45 ppm and 90 ipm | The 45 ppm headline for Canon holds in other modes. |
| Operating depth | 23.1 inches | 18.78 inches | With the ScanSnap, open-tray depth is 4.32 inches less. |
| Application driver | TWAIN route | ScanSnap-specific, no TWAIN | The software you already have can overturn a recommendation based on the feeder. |
| Power | AC adapter with USB data | AC adapter with USB data | The USB-C data connector alone powers neither. |
Trade-offs
What each pick costs you
With Canon imageFORMULA R40 II
- An AC adapter is required. Color scanning at 300 dpi is rated at 40 ppm, not 45 ppm.
With Ricoh ScanSnap iX2400
- An existing capture application can't use it, because there's no TWAIN support.
Change of plan
When the answer changes
You often go beyond 60 sheets and are able to use ScanSnap Home
Go with Ricoh ScanSnap iX2400. A refill is taken away by the 100-sheet feeder.
Your current application depends on TWAIN acquisition
Go with Canon imageFORMULA R40 II. That route works on the Canon.
You want scanning from a phone alone, with no computer connected
Neither model fits. Both configurations compared are USB host workflows and neither has Wi-Fi.
Decision guide
How to decide
Pick the iX2400 for large loose-paper batches and a shorter open-tray depth. Pick the R40 II if its TWAIN route fits the Windows software you already use and a 60-sheet feeder is enough.
The forty-five-ppm headline isn't the same color job on both
For the R40 II, Canon rates grayscale at 300 dpi at 45 ppm, but color at 300 dpi drops to 40 ppm. The iX2400 stays at 45 ppm for A4 color at 300 dpi. With color originals, compare those mode-specific figures and not the two headline numbers. Both are manufacturer ratings. Image processing, computer performance and saving time stay outside this comparison.
On a shallow desk, the bigger feeder can win
Even though it holds more sheets, the iX2400 lists an operating depth of 18.78 inches, against 23.1 inches for the R40 II. That saves 4.32 inches of front-to-back room. The stated access and cable allowances still apply, and feeder size alone doesn't predict how well it fits your desk. 23.1 minus 18.78 equals 4.32 inches. Both values are expanded operating dimensions. They do not describe closed storage.
A ninety-sheet folder and an existing app can pull in opposite directions
The iX2400 takes ninety ordinary sheets in a single load, while the R40 II needs two loads. But if your software requires TWAIN, the Canon's application route may matter more than skipping that reload. ScanSnap would need its own capture step, followed by importing the file. 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, and larger sheets reduce its stated capacity to 50.
What this page can’t tell you
- Manufacturer feed ratings leave out document preparation, OCR and saving time.
- Confirm the supported media, the scan mode, your current operating system and the destination before you purchase.
