Main trade-off
Ricoh ScanSnap SV600
The supported thickness is 30 mm, so very thick books are outside its specification.
Head-to-head
ScanSnap SV600 vs Canon CanoScan LiDE 400: SV600 covers larger open pages within thickness limits
The short answer
Choose the SV600 for larger open pages and repeated book scanning within its thickness limits. Choose the LiDE 400 for Letter-sized flat originals and high optical sampling when manual placement is acceptable.
Before you choose
The reasoning and the trade-offs
A wide original can choose the scanner before resolution does
The SV600 covers up to 17 by 11.8 inches for thin originals, roughly double the LiDE 400's 8.5-inch bed width. If a school art project or drawing exceeds the flatbed, overhead capture may avoid separately placed sections. Thicker originals have a tighter size allowance.
What this is based on
For SV600 originals over 5 mm thick, the maximum width is 400 mm, about 15.75 inches. The overall thickness limit remains 30 mm.

About this comparison
Compare overhead book scanning with a high-resolution flatbed. Original size, book thickness and page-turning work matter more than output dpi.
Choose the SV600 for larger open pages and repeated book scanning within its thickness limits. Choose the LiDE 400 for Letter-sized flat originals and high optical sampling when manual placement is acceptable.
Winner by situation
Start with what you need it to do
Repeated scanning of an open book within 30 mm thickness
The SV600's face-up placement and page-turn detection match that job.

Thick books over 30 mm
The SV600 limit excludes them, and Canon still needs suitable flatbed placement.

What matters in practice
The differences that matter
A wide original can choose the scanner before resolution does
The SV600 covers up to 17 by 11.8 inches for thin originals, roughly double the LiDE 400's 8.5-inch bed width. If a school art project or drawing exceeds the flatbed, overhead capture may avoid separately placed sections. Thicker originals have a tighter size allowance.
How we reached this conclusion
For SV600 originals over 5 mm thick, the maximum width is 400 mm, about 15.75 inches. The overall thickness limit remains 30 mm.
Book thickness can reverse the overhead recommendation
The SV600's 30 mm limit is about 1.18 inches. A thick bound volume outside that envelope is not automatically supported just because it fits under the camera head. The LiDE 400's lid can expand, but the book still needs to suit a flatbed workflow without forcing its binding.
How we reached this conclusion
Neither product provides universal support for all book thicknesses. Document condition and page curvature still matter.
Page-turn detection saves a repeated action, not the page turn itself
The SV600 can start a capture when it detects a page turn, which can help during a long book session. You still turn and position each page. The LiDE 400 requires manual placement and capture, but its higher optical sampling can be useful for detailed flat originals.
How we reached this conclusion
The SV600's 3-second scan interval excludes page handling, and its 1200 dpi output is not 1200 dpi optics. No OCR accuracy advantage is assumed.
Choice A
Ricoh ScanSnap, SV600
SV600
Leave a book open on the scan mat and capture pages from above without sending them through rollers.
- Best matched use
- You need to capture larger open pages from above
Checked facts

- Maximum area: 17 by 11.8 inches for originals up to 5 mm thick
- Thick-original boundary: 30 mm maximum, 400 mm width above 5 mm thickness
- Optical sampling: 218 to 285 dpi horizontal and 152 to 283 dpi vertical
Choice B
Canon, CanoScan LiDE 400
CanoScan LiDE 400
Place a photo or a book page on the glass when rollers would be the wrong way to handle it.
- Best matched use
- Your originals fit a Letter or A4 flatbed
Checked facts
- Scan method: Contact flatbed
- Maximum area: 8.5 by 11.7 inches
- Thick-original boundary: Expansion lid, check the original and lid clearance
- Optical sampling: 4800 dpi optical
Meaningful differences
What changes the fit
| What changes | Ricoh ScanSnap SV600 | Canon CanoScan LiDE 400 | Why it matters |
|---|---|---|---|
| Scan method | Overhead | Contact flatbed | The book stays face up under the SV600 rather than on the glass. |
| Maximum area | 17 by 11.8 inches for originals up to 5 mm thick | 8.5 by 11.7 inches | Larger artwork can exceed the Canon bed. |
| Thick-original boundary | 30 mm maximum, 400 mm width above 5 mm thickness | Expansion lid, check the original and lid clearance | The SV600's largest area does not apply to every thick book. |
| Optical sampling | 218 to 285 dpi horizontal and 152 to 283 dpi vertical | 4800 dpi optical | High output dpi is not the SV600's optical capture measure. |
| Power | AC adapter plus USB data | USB power and data | Canon avoids a separate wall adapter. |
What you give up
Every choice has a cost
If you choose Ricoh ScanSnap SV600
- Advertised output resolution is not the same as the variable 218 to 285 dpi horizontal optical sampling.
If you choose Canon CanoScan LiDE 400
- Auto Scan is not available when using upright scanning mode.
Recommendation switch
The decision flips if...
You repeatedly scan supported books or wider thin originals
Choose Ricoh ScanSnap SV600. Overhead placement and page-turn detection add practical value.
Letter-sized flat detail and USB power are the priorities
Choose Canon CanoScan LiDE 400. The LiDE 400 fits that different job.
The original cannot fit either documented area or thickness workflow
Choose neither. Choose a scanner with explicit support rather than forcing the original.
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.
