Main trade-off
Brother ADS-1800W
The 20-sheet office-paper feeder means two reloads after the first load for the stated 60-sheet job.
Head-to-head
Choose ADS-1800W for small batches between desks when a direct computer USB-C port supplies at least 15 W and your paper meets its limits. Its US base box has no AC adapter. Choose ES-590W for a recurring 60-sheet stack of clean, loose 80 g/m² Letter/A4 paper when you have AC power and space for its 612 mm open depth, more than 10 cm behind it, and a stack under 12 mm. That job needs one Epson load instead of three Brother loads, avoiding two reloads. Heavier paper changes those capacities. Neither is a flatbed for bound books or originals that must not pass through rollers.
Before you choose
For 60 clean, loose Letter/A4 sheets of one 80 g/m² stock, Brother needs three loads. Epson can hold the whole pile in one load if it stays under 12 mm thick. That removes two capacity-driven reloads. It does not remove preparation, checking or saving the result. If your normal pile contains 20 sheets or fewer, both can take it in one load and this reason to choose Epson disappears.
What this is based on
The calculation uses each manual's feeder rating for the same ordinary paper. Duplex changes the number of page images, not the number of physical sheets you load.
Main trade-off
The 20-sheet office-paper feeder means two reloads after the first load for the stated 60-sheet job.
Main trade-off
It needs the supplied AC adapter and an outlet, even when the data connection is wireless.


Compare Brother ADS-1800W and Epson ES-590W by paper loading, USB-C power and heavier forms, with setup limits that can change your choice.
A scanner you bring to a laptop and one that stays beside a weekly paperwork pile can do the same document job with different interruptions. Brother can save the search for a wall outlet. Epson can save repeat feeder loading. Neither benefit follows just from having Wi-Fi or a touchscreen.
Winner by situation
Epson avoids two capacity-driven reloads if the clean, loose stack stays under 12 mm. It still needs AC power and 612 mm open depth, with more than 10 cm behind the scanner. Brother handles the same supported paper in three loads with suitable power.
Brother can use its included cable directly from a USB-C port supplying at least 15 W, with space for the paper exit. Epson needs its AC adapter and open-tray space. Do not assume every USB-C laptop port qualifies.
With at most 20 clean, loose 80 g/m² Letter/A4 sheets, both can use one load. Brother still needs a qualifying host or separately purchased power supply. Check complete package cost, destination and working clearance rather than treating feeder size as a winner.
Those forms exceed Brother's standard-paper weight limit. Epson supports that weight up to 50 sheets and a stack under 12 mm, with AC power, the 612 mm open depth and more than 10 cm behind the scanner. This does not cover glossy photos or arbitrary card stock.
Both are document feeders. Use a suitable flatbed or overhead capture workflow when the original must not be separated into sheets or moved through rollers.
What matters in practice
For 60 clean, loose Letter/A4 sheets of one 80 g/m² stock, Brother needs three loads. Epson can hold the whole pile in one load if it stays under 12 mm thick. That removes two capacity-driven reloads. It does not remove preparation, checking or saving the result. If your normal pile contains 20 sheets or fewer, both can take it in one load and this reason to choose Epson disappears.
The calculation uses each manual's feeder rating for the same ordinary paper. Duplex changes the number of page images, not the number of physical sheets you load.
With a direct computer port supplying at least 15 W, Brother's included USB-C cable can carry the power needed for scanning. That can simplify moving between desks without finding an outlet for another adapter. A low-output port or USB-A adapter removes that advantage and needs optional AC power. Epson uses its supplied AC adapter. At a permanent desk with an outlet already available, this distinction may matter much less.
The connector shape does not establish the power output. The Brother US support article explicitly names both the threshold and the fallback purchase.
Suppose the recurring job is ten clean, uncoated Letter forms on 157 g/m² paper. That is already outside Brother's 128 g/m² standard-paper ceiling, despite being well below 20 sheets. Epson lists 50-sheet capacity at that weight, subject to its paper and stack rules. This is a media-fit reason to choose Epson independently of a large pile. Coated, damaged or irregular originals need separate handling checks.
These are published standard-paper limits. Brother's separate plastic-card slot does not extend the weight range for full-size paper.

Brother, ADS-1800W
A touchscreen duplex scanner with a 20-sheet feeder and a 3.1 lb body. Its included USB-C cable can power it from a direct computer port supplying at least 15 W. The US base package has no AC adapter.

Epson, ES-590W
A touchscreen duplex scanner with a 100-sheet rating for 80 g/m² Letter/A4 paper. It uses the supplied AC adapter and reaches 612 mm deep with trays open. Heavier paper reduces the load size.
Meaningful differences
| What changes | Brother ADS-1800W | Epson ES-590W | Why it matters |
|---|---|---|---|
| A 60-sheet office-paper job | Three loads, with two reloads after the first | One load, with no capacity-driven reload | This is a loading count for 60 clean, loose Letter/A4 sheets of the same 80 g/m² stock, within both paper limits. It is not a measured scan-time saving or a promise of unattended completion. |
| Working without an AC outlet | Included USB-C cable can use a direct computer port supplying at least 15 W | Uses the supplied AC adapter and an outlet | Brother can remove the wall-power step only with a qualifying host port. A USB-C connector alone is not enough, and its base box has no AC adapter. |
| Standard paper weight | 51.8 to 128 g/m², also 0.08 to 0.14 mm thick | 27 to 413 g/m² for supported standard paper | A clean uncoated 157 g/m² Letter form is outside Brother's standard-paper weight range. Epson lists up to 50 such sheets, not the 100-sheet office-paper headline. |
| Scanner body carried between desks | About 3.1 lb or 1.42 kg | About 8.2 lb or 3.7 kg | Brother is the lighter body to lift. Add the cables, power accessories and carrying protection you actually use before comparing the travel kit. |
| Direct USB-drive filing | USB mass storage up to 128 GB, FAT12/FAT16/FAT32/exFAT | Up to 2 TB, FAT/FAT32/exFAT, without password or encryption settings | Both have a touchscreen USB route without a computer processing each scan. Match the drive to the scanner and arrange power separately. Epson also excludes devices requiring a dedicated driver. |
| Space while paper is moving | Open the cover and support arms, with room for the sheets to exit | 612 mm scanning depth and 319 mm height with trays open | Storage dimensions are not the working footprint. For Epson, also allow cable access and more than 100 mm behind it when placed by a wall. Brother's short cabinet does not contain the whole moving sheet. |
What you give up
Recommendation switch
Choose Brother ADS-1800W. Choose ADS-1800W when its included cable removes the extra wall-power step. Leave room for document travel. A low-output port or USB-A adapter needs optional AC power instead.
Choose Epson ES-590W. Choose ES-590W to avoid two capacity-driven reloads. Allow its 612 mm open depth and more than 10 cm behind the scanner. This calculation does not promise unattended completion or faster finished files.
Choose Epson ES-590W. Choose ES-590W if AC power, the 612 mm open depth and more than 10 cm behind the scanner are available. Brother's standard-paper range stops at 128 g/m² even when the pile is small.
Choose neither. Choose an appropriate flatbed or overhead workflow. A document feeder and an optional carrier sheet do not provide stationary scanning.
What matters in practice
Count the times you reload a normal job, then check where power and moving paper will go. Verify the destination workflow separately.
