Main trade-off
Brother ADS-3100
There is no Wi-Fi or Ethernet connection.
Head-to-head
Choose the ADS-3350W when more than one computer needs the scanner or you want named touchscreen jobs. The ADS-3100 is the simpler fit for one USB-connected computer handling the same size of scan packets.
Before you choose
The ADS-3350W can sit on Ethernet or Wi-Fi instead of being tied to one computer's USB port. In a shared home office, that can avoid moving a laptop or passing the cable between users. It does not guarantee that every device on a guest or isolated network can reach it.
What this is based on
Both devices retain USB. Network visibility depends on the router and supported application.
Main trade-off
There is no Wi-Fi or Ethernet connection.
Main trade-off
A 2.8-inch screen gives less viewing area than Brother's 4.3-inch models.


Compare a dedicated USB scanner with a shared network model. The useful upgrade is access and job selection, not a faster 60-sheet feeder.
Choose the ADS-3350W when more than one computer needs the scanner or you want named touchscreen jobs. The ADS-3100 is the simpler fit for one USB-connected computer handling the same size of scan packets.
Winner by situation
Both have the same feeder capacity and rated speed.
Ethernet avoids physically moving the USB connection.
Both feeders take 60 suitable sheets.
The touchscreen makes destinations visible at the scanner.
What matters in practice
The ADS-3350W can sit on Ethernet or Wi-Fi instead of being tied to one computer's USB port. In a shared home office, that can avoid moving a laptop or passing the cable between users. It does not guarantee that every device on a guest or isolated network can reach it.
Both devices retain USB. Network visibility depends on the router and supported application.
Each feeder takes 60 ordinary sheets. A 90-sheet packet needs a first load and one reload whichever model you buy. If reducing feeder visits is the main goal, the ADS-3350W's screen is not the upgrade that solves it.
Ceiling of 90 divided by 60 equals two loads. Thick or mixed originals can lower effective capacity.
Named touchscreen jobs on the ADS-3350W can keep a household archive, invoices and shared work records as separate choices. If every scan goes to one inbox and one person does the sorting, the ADS-3100's simpler controls are less of a compromise.
Saved jobs still need correct initial setup and destination access. This is a workflow advantage, not an error-rate claim.

Brother, ADS-3100
Give one computer a 60-sheet scanner for recurring paperwork without adding wireless setup.

Brother, ADS-3350W
Share a 60-sheet scanner over Ethernet or Wi-Fi and choose routine jobs from its touchscreen.
Meaningful differences
| What changes | Brother ADS-3100 | Brother ADS-3350W | Why it matters |
|---|---|---|---|
| Network access | USB only | Wi-Fi and Ethernet plus USB | The ADS-3350W can serve a reachable shared network. |
| Job selection | Physical controls | 2.8-inch touchscreen | Named jobs are available without returning to the computer. |
| Feeder capacity | 60 sheets | 60 sheets | The upgrade does not remove a refill for a 90-sheet packet. |
| Single-sided scan rate | 40 ppm at Letter 300 dpi | 40 ppm at Letter 300 dpi | The documented single-sided feed rating gives no speed reason to upgrade. |
What you give up
Recommendation switch
Choose Brother ADS-3350W. The ADS-3350W adds both Ethernet and Wi-Fi.
Choose Brother ADS-3100. The scan engine and feeder cover the same ordinary packet size.
Choose neither. Compare a 100-sheet model such as the ADS-4900W.
