The catch
Epson ES-C220
No workflow for scanning straight to a phone is documented.
Side by side
The ES-C320W fits ordinary supported pages sent to a compatible phone or tablet through Epson Smart Panel, as long as you have AC power and a supported wireless connection. The ES-C220 fits when a nearby compatible computer handles the scans and its complete price is better. Both have a 20-sheet feeder. On either model, long originals need computer software, the straight path, hand support and the permitted resolution.
Before you buy
When long receipts are why you are buying, the mobile support on ES-C320W does not cover the job, since Smart Panel excludes long paper. Through the computer workflow, Epson permits paper over 15.5 inches and up to 120 inches at 50 to 300 dpi. If you need those lengths above 300 dpi, neither model meets the documented mode.
Where this comes from
Long originals are excluded from Smart Panel by Epson. Work through the computer software, at the resolution allowed for that length.
The catch
No workflow for scanning straight to a phone is documented.
The catch
Smart Panel does not work with long paper. Originals over 15.5 inches call for the computer workflow at 50 to 300 dpi.

Phone scanning, feeder limits the models share and the paper-path change that both compact Epson scanners need are covered here.
The document mechanism is shared by these two compact Epson models, and they differ mainly in wireless access. What is worth comparing is whether wireless holds up in the buyer’s actual document mode.
Which one fits
In Smart Panel, ES-C320W handles ordinary supported pages given a compatible mobile device, AC power and a supported wireless connection.
ES-C220 is not the mobile model, and on ES-C320W long paper is excluded from Smart Panel.
Each takes two 20-sheet loads and supports a computer workflow.
The tilted straight path and hand support at the entry and exit are needed on both. Use computer software and the permitted resolution. The upright footprint says nothing about the space or attention this job takes.
In practice
When long receipts are why you are buying, the mobile support on ES-C320W does not cover the job, since Smart Panel excludes long paper. Through the computer workflow, Epson permits paper over 15.5 inches and up to 120 inches at 50 to 300 dpi. If you need those lengths above 300 dpi, neither model meets the documented mode.
Long originals are excluded from Smart Panel by Epson. Work through the computer software, at the resolution allowed for that length.
For long originals the scanner has to tilt into the straight path. Epson also instructs you to support the sheet with both hands at the input and the output. Leave room, and expect to stay with the scan. A claim about compact vertical mode does not promise that a long receipt can run unattended in the same footprint.
Following the long-paper instructions means using the straight path and supporting the sheet at both entry and exit. The compact upright footprint does not apply to that procedure.
On either model, a 40-sheet packet still takes two initial feeder loads. What ES-C320W changes is where ordinary scans can go, and not how many sheets the feeder holds. If a large backlog is your problem, compare a larger ADF.
The published feeder on each holds up to 20 supported sheets. Wi-Fi changes how you reach the scanner and leaves that loading limit alone.

Epson, ES-C220
A computer scanner with a 20-sheet capacity and both upright and straight paper paths. For long originals you need the straight path, hand support and the allowed resolution.

Epson, ES-C320W
Phone scanning through Smart Panel works for ordinary supported pages, given AC power and a supported wireless connection. Long paper still needs a computer.
Spec by spec
| Spec | Epson ES-C220 | Epson ES-C320W | In practice |
|---|---|---|---|
| Input and duplex rating | 20 sheets, up to 30 ppm / 60 ipm | 20 sheets, up to 30 ppm / 60 ipm over USB | A larger feeder does not come with the wireless model. The published speed is no guaranteed result over mobile Wi-Fi. |
| Phone scanning | Computer-centered USB workflow | Epson Smart Panel over Wi-Fi | Decide based on the device that receives ordinary scans. |
| Long originals | Up to 120 inches in the correct path | Up to 120 inches, unavailable in Smart Panel | For long paper, the wireless model still depends on the supported computer workflow. |
| Compact-space claim | Vertical document path | Vertical document path | Because long paper runs through a tilted straight route, set aside space for that operating position as well. |
Trade-offs
Change of plan
Go with Epson ES-C320W. Pick ES-C320W for this phone workflow. Long paper still takes a computer, the straight path, hand support and the allowed resolution.
Go with Epson ES-C220. Favor ES-C220 when a compatible computer, AC power and the required paper path cover the job and its current complete offer is better. Long-paper jobs need hand support and cannot go through Smart Panel.
Neither model fits. Look into a larger ADF instead of the same feeder with Wi-Fi added.
Decision guide
For ordinary supported pages sent to a compatible phone or tablet through Epson Smart Panel, with AC power and a supported wireless connection, pick the ES-C320W. If a nearby compatible computer handles the scans and its complete price is better, pick the ES-C220. Both have a 20-sheet feeder, and on either model long originals need computer software, the straight path, hand support and the permitted resolution.
