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.

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.
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.
