Head-to-head
Epson ES-400 II vs ES-580W: 580W holds bigger stacks, rated scan speed is equal
The short answer
Choose the ES-580W for 51- to 100-sheet packets, wireless access or direct USB memory saving. Choose the ES-400 II for shorter batches at one computer, since both share the same published 35 ppm scan rate.
Before you choose
The reasoning and the trade-offs
An eighty-sheet packet needs one fewer reload
The ES-580W can accept 80 ordinary sheets in its 100-sheet feeder. The ES-400 II's 50-sheet feeder needs two loads. That is useful when you want to start a folder before returning to another task.
What this is based on
The calculation assumes suitable uniform paper and excludes hand-fed special media.
Main trade-off
Epson ES-580W
The rated 35 ppm is lower than the newer ES-590W's 45 ppm.

About this comparison
Compare a 50-sheet USB scanner with a 100-sheet touchscreen model. Large packets and computer-free USB saving matter more than speed here.

What matters in practice
The differences that matter
An eighty-sheet packet needs one fewer reload
The ES-580W can accept 80 ordinary sheets in its 100-sheet feeder. The ES-400 II's 50-sheet feeder needs two loads. That is useful when you want to start a folder before returning to another task.
How we reached this conclusion
The calculation assumes suitable uniform paper and excludes hand-fed special media.
Paying more does not shorten the rated feed time
Both are rated at 35 ppm and 70 ipm for Letter scans at 300 dpi. A short 20-sheet packet fits either feeder. For that routine, the ES-580W earns its price through destinations and sharing rather than faster paper movement.
How we reached this conclusion
Finished job time varies with settings, host software and storage. No matched hands-on speed test is claimed.
A USB stick can remove the wait for the household computer
The ES-580W can save directly to a supported memory drive without a computer. This is useful when the shared laptop is occupied, provided the drive and format fit Epson's requirements. The ES-400 II normally needs its connected host to receive the files.
How we reached this conclusion
Direct USB capture is separate from cloud upload. Cloud workflows may still require software, network access and an account.

Meaningful differences
What changes the fit
| What changes | Epson ES-400 II | Epson ES-580W | Why it matters |
|---|---|---|---|
| Feeder | 50 sheets | 100 sheets | The ES-580W crosses an important packet-size threshold. |
| Connection | USB computer connection | USB and Wi-Fi | The larger model can be placed away from the receiving computer. |
| Controls | Buttons | 4.3-inch touchscreen | The screen provides on-device destination choices. |
| USB memory destination | No | Yes | Capture can happen before a computer is available. |
| 300 dpi scan rating | 35 ppm and 70 ipm | 35 ppm and 70 ipm | The upgrade is capacity and workflow, not rated feed speed. |
What you give up
Every choice has a cost
If you choose Epson ES-400 II
- The paper trays extend beyond its storage footprint.
If you choose Epson ES-580W
- Cloud workflows have account and software requirements that differ from direct USB saving.
Recommendation switch
The decision flips if...
Your regular packets contain between 51 and 100 sheets
Choose Epson ES-580W. The larger feeder directly removes a reload.
Short USB-connected batches cover the whole job
Choose Epson ES-400 II. The smaller model provides the same rated feed speed.
Originals cannot be separated from a book
Choose neither. 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.
