Head-to-head
Epson ET-4950 vs Canon GX6120: Scan both sides or load more originals?
The short answer
Choose ET-4950 for suitable two-sided Letter or A4 records and when fax is required. Choose GX6120 for larger one-sided stacks and alternating supported papers: it has a 50-sheet Letter feeder and separate 250-sheet cassette plus 100-sheet rear tray. Canon’s feeder is single-sided, and its scanner does not turn a 50-sheet stack into automatic both-side archiving. Epson takes 30 Letter sheets, but its duplex-scan advantage does not extend to Legal originals.
Before you choose
The reasoning and the trade-offs
A 40-sheet archive favors different printers depending on what is on the backs
Forty one-sided Letter originals fit within Canon’s 50-sheet feeder capacity in one load. Epson’s 30-sheet feeder needs two loads. If those same originals have useful content on both sides, Epson can capture the backs automatically for supported Letter or A4 paper, while Canon needs manual handling for the second side. The larger number therefore does not settle which printer asks less of an interrupted home worker. Count loads and side changes separately, then inspect the finished file on either model.
What this is based on
An interrupted home worker plus mixed one-sided and two-sided records crossed with feeder capacity and scan direction. Forty originals require one versus two loads, but no total-time winner is calculated.
Main trade-off
Canon MegaTank GX6120
No automatic two-sided scanning or fax. The larger feeder headline describes one-sided handling.

- Main trade-off
- 30-sheet output and a 30-sheet Letter feeder. Legal scanning is single-sided.
Canon MegaTank GX6120
- Choose it for
- Load up to 50 supported Letter originals for a one-sided scan batch.
- Keep plain paper in the cassette while another supported paper uses the rear tray.
- Main trade-off
- No automatic two-sided scanning or fax. The larger feeder headline describes one-sided handling.
About this comparison
Epson ET-4950 vs Canon GX6120 for two-sided records, long one-sided stacks and a shared work printer. Compare the handling behind the feeder capacities.
Both are refillable home-office all-in-ones with Ethernet and automatic duplex printing. A buyer stepping up for less manual work can plausibly choose between Epson’s smaller duplex feeder and Canon’s larger single-sided feeder with two paper sources.

What matters in practice
The differences that matter
A 40-sheet archive favors different printers depending on what is on the backs
Forty one-sided Letter originals fit within Canon’s 50-sheet feeder capacity in one load. Epson’s 30-sheet feeder needs two loads. If those same originals have useful content on both sides, Epson can capture the backs automatically for supported Letter or A4 paper, while Canon needs manual handling for the second side. The larger number therefore does not settle which printer asks less of an interrupted home worker. Count loads and side changes separately, then inspect the finished file on either model.
How we reached this conclusion
An interrupted home worker plus mixed one-sided and two-sided records crossed with feeder capacity and scan direction. Forty originals require one versus two loads, but no total-time winner is calculated.
The second tray can protect tomorrow morning’s routine
A child’s supported project paper can use the GX6120 rear tray while ordinary work paper stays in the 250-sheet cassette. That reduces the chance that the next person must unload one paper to restore the other. The driver still needs the correct source, size and type, and leftover settings can affect the next job. ET-4950’s single main input makes this a more direct reload-and-reset task. Canon’s advantage is strongest when the household genuinely alternates media, not when both trays would hold the same paper.
How we reached this conclusion
After-school projects plus next-morning work documents crossed with separate paper sources and the required settings reset. No claim of automatic error prevention or universal specialty-media compatibility.
Legal records and fax needs can overturn the attractive headline
Both feeders fall to ten sheets for Legal originals, and both require manual handling of the backs at that size. Canon’s larger Letter stack is no longer an advantage there. Epson also includes fax, while GX6120 is a print, scan and copy model. For a household handling long documents with an organization that still requires a compatible fax connection, check that requirement before paying for a faster print specification. Neither Letter-size glass solves a fragile Legal original that cannot use a feeder.
How we reached this conclusion
Long administrative paperwork plus an external organization’s required delivery method crossed with Legal capacity, flatbed size and fax function. Fax service and line compatibility remain buyer checks.

What changes the fit
| What changes | Epson EcoTank ET-4950 | Canon MegaTank GX6120 | Why it matters |
|---|---|---|---|
| Letter original feeder | 30 sheets, automatic both-side scanning. | 50 sheets, single-sided scanning. | Capacity and direction answer different questions. |
| Legal originals | 10 sheets, single-sided. | 10 sheets, single-sided. | For Legal paperwork, the headline Letter advantage changes on both machines. |
| Two papers in the household | 250-sheet main input. | 250-sheet cassette plus 100-sheet rear tray. | Canon can keep a supported second medium in a separate source. |
| Office functions and speed | Fax, Ethernet, 18 black and 9 color ISO ppm. | No fax, Ethernet, 24 black and 15.5 color ISO ipm. | Check the required function before comparing standardized speed. No mixed-job timing is inferred. |
What you give up
Every choice has a cost
If you choose Epson EcoTank ET-4950
- Changing the paper type in the main source can leave the next household user with another setup task.
If you choose Canon MegaTank GX6120
- A two-sided archive still needs a manual second pass and order check. Two print trays do not change that scanner limitation.
Recommendation switch
The decision flips if...
Most archived Letter forms have content on both sides
Choose Epson EcoTank ET-4950. Automatic both-side scanning addresses the repeated job.
Originals are mostly one-sided and the household alternates papers
Choose Canon MegaTank GX6120. The larger feeder and second print source address both tasks.
What matters in practice
Before you choose
A larger feeder reduces reloads for one-sided originals, while a smaller duplex feeder removes the separate job of turning the backs.
What this comparison cannot tell you
- No measured end-to-end scan or print timing.
- Automatic duplex scanning is size-limited on Epson.
- Separate paper trays do not establish support for every craft material.
