Quick Verdict
The Epson WorkForce Pro WF-3820 is a wireless color inkjet all-in-one built for small offices that need print, scan, copy, and fax with real paper capacity to back it up. Its 250-sheet main tray and 35-sheet automatic document feeder handle noticeably more volume than a typical home printer, and Epson's business-oriented WorkForce line is built around business documents rather than photos. The tradeoffs are a plain, function-first design and cartridge-based ink that costs more per page than a refillable tank printer. At a typical street price well under its $199.99 list price, it's a solid value for small office paperwork.

Who This Printer Is For
This is a good match for a small office or busy home office that regularly scans or copies multi-page documents and needs enough paper capacity to avoid constant refilling. The automatic document feeder and fax support cover real business needs that a basic home inkjet skips, and the 250-sheet main tray means less time spent reloading paper during busy periods. It's also a reasonable pick for anyone who wants Epson's print quality without stepping up to a cartridge-free EcoTank model.
Who Should Skip It
Skip it if you print in high volume every day, since standard ink cartridges will cost more over time than a refillable tank printer like an Epson EcoTank model. It's also more machine than you need if you only print occasional single pages at home — a smaller, cheaper inkjet will serve that use case just as well without the added footprint and paper capacity you won't use.
What People Love
Owners consistently mention how much paper capacity this printer holds compared to typical home inkjets, with the 250-sheet tray and 35-sheet ADF getting called out as genuinely useful for office-style workloads. Print speed and quality for text documents get solid marks, and several buyers specifically mention upgrading from a smaller inkjet and appreciating the reduced need to refill paper constantly. The fax function, while less commonly used, is noted as a helpful inclusion for small business needs.
The Legitimate Complaints
The most common complaint is ink cost over time, since standard cartridges cost more per page than a refillable tank system, which matters if you print heavily every day. Some owners also mention that setup and driver installation can be finicky on certain operating systems, and a smaller number report occasional paper feed jams with the automatic document feeder if pages aren't loaded carefully.
How It Compares
- Canon PIXMA MG3620 (Cheaper, ~$104): Print, scan, copy without ADF or fax — best for basic home printing on a tight budget.
- Epson WorkForce Pro WF-3820 (This Model, ~$100-200): Print, scan, copy, fax with 250-sheet capacity and ADF — best for a small office with real paper volume.
- HP OfficeJet Pro 9125e (Upgrade, ~$200): Faster print speeds and a two-sided automatic document feeder — best for a busier office needing quicker turnaround.
Cheaper Alternative: Canon PIXMA MG3620
If you don't need fax or an automatic document feeder, our Canon PIXMA MG3620 review covers a simpler, less expensive all-in-one for basic home printing.
Upgrade Pick: HP OfficeJet Pro 9125e
For a busier office that scans two-sided documents often, our HP OfficeJet Pro 9125e review covers a step up with faster speeds and two-sided scanning.
Ink and Supplies
The WF-3820 uses Epson 822 (standard yield) or Epson 822XL (high yield) ink cartridges in black, cyan, magenta, and yellow. Castle Ink stocks compatible Epson 822/822XL cartridges at a meaningful discount to genuine Epson pricing, which helps offset this printer's higher cost per page compared to a tank-based system.
Frequently Asked Questions
Does it support automatic two-sided printing?
Yes, automatic duplex printing is built in for both copies and print jobs.
How much paper can it hold?
The main tray holds up to 250 sheets, and the automatic document feeder holds up to 35 sheets for scanning, copying, and faxing multi-page documents.
Is this a tank-based or cartridge-based printer?
It's cartridge-based, using Epson 822/822XL ink cartridges. If you want a refillable tank system instead, an Epson EcoTank model would be a better fit.
What It Actually Costs to Run
The purchase price of an inkjet tells you very little about what it costs to own. The WF-3820 takes Epson 822 and 822XL DURABrite Ultra cartridges, and the gap between those two sizes is the single biggest lever on your running cost — the standard cartridges exist mainly because they are what ships in the box.
Two things work in this printer’s favour on cost. The first is that DURABrite Ultra is a pigment ink rather than a dye, so text on plain paper comes out sharp, dries fast and does not smear under a highlighter — you are not forced onto expensive coated paper to get a professional-looking document. The second is that the same 822 cartridges fit the WorkForce Pro WF-4820, WF-4830 and WF-4834, so an office running more than one Epson can standardise on a single ink set instead of stocking three.

Things Worth Knowing Before You Buy
None of these are reasons to avoid the WF-3820, but they are the things owners wish they had known on day one.
Pigment ink does not like sitting idle. Every inkjet dries out if unused, but pigment inks are less forgiving than dyes. If this printer is going to sit untouched for weeks at a time, print a page of colour once a week — it uses far less ink than the cleaning cycles you will otherwise trigger trying to unclog it.
There is a maintenance box, and it is a consumable. Epson WorkForce Pro models collect waste ink in a user-replaceable box. Eventually the printer will tell you it is full and stop until you swap it. It is inexpensive and takes a minute to change, but it catches people out because nobody expects a second consumable.
Wireless can be sticky after a router change. Like most network printers, the WF-3820 holds on to the address it was given. If it starts showing as offline after your router restarts, that is a network address problem rather than a fault — our guide to why printers keep going offline has the permanent fix.
More Questions Owners Ask
Can I use compatible cartridges in the WF-3820? Yes. Epson will show a message noting the cartridge is not genuine; the printer keeps working. As with every manufacturer, it is worth buying from somewhere that stands behind the cartridge with a replacement warranty rather than chasing the lowest price on a marketplace.
Will it print if one colour is empty? No. Like almost every colour inkjet, all four cartridges need ink installed before it will print anything, including a black-and-white document.
Is it worth buying XL cartridges from the start? For almost everyone, yes. The XL cartridges cost more up front and dramatically less per page. The only case for standard cartridges is a printer that genuinely prints a handful of pages a month, and even then the XLs will usually still work out cheaper before they expire.
How does it compare to an EcoTank? Different economics entirely. An EcoTank costs considerably more up front and much less per page, which pays off at high volume. For moderate home-office volumes the WF-3820 with compatible XL cartridges lands in a similar place for a fraction of the initial outlay.
Bottom Line
The Epson WorkForce Pro WF-3820 delivers genuine small-office functionality — real paper capacity, an automatic document feeder, and fax — at a price that's often discounted well below its list price. It's a smart pick for office-style workloads, though heavy daily printers will save more long-term with a refillable tank printer instead.
