Fast A4 Business Printing
The Epson WorkForce Pro WF-3820 uses Epson's PrecisionCore business inkjet technology to deliver fast, professional-quality office documents.
Print speeds reach up to 21 ISO pages per minute in black and 11 ISO pages per minute in colour, making it well suited to invoices, quotations, reports, correspondence, presentations and everyday business documents.
Automatic 2-Sided Duplex Printing
Built-in automatic duplex printing allows the WF-3820 to print on both sides of compatible paper without manually turning pages over.
Automatic 2-sided print speeds reach up to 12 ISO ppm black and 7 ISO ppm colour, helping businesses reduce paper consumption while producing professional double-sided documents.
35-Sheet Automatic Document Feeder
The integrated 35-sheet Automatic Document Feeder (ADF) makes scanning, copying and faxing multi-page A4 documents considerably easier than feeding each page individually on the scanner glass.
The WF-3820 is therefore particularly useful for offices regularly handling invoices, contracts, forms and other multi-page documents.
250-Sheet Paper Cassette
A 250-sheet front paper cassette provides practical capacity for everyday business printing and reduces the frequency of paper refills compared with smaller home inkjet printers.
The WF-3820 supports common office media including A4, A5, A6, B5, B6, Legal and envelopes, with borderless printing available on selected media sizes including A4.
2.7" Colour Touchscreen
The built-in 2.7-inch colour touchscreen LCD provides convenient access to printing, scanning, copying, faxing and network functions directly from the printer.
Wired & Wireless Network Connectivity
The WF-3820 offers flexible connectivity for individual users and shared office environments.
- ✔ USB 2.0
- ✔ USB Host
- ✔ Ethernet 10/100
- ✔ Wi-Fi
- ✔ Wi-Fi Direct

Built-in Ethernet allows the WF-3820 to operate as a shared network printer, while Wi-Fi and Wi-Fi Direct provide convenient wireless printing from compatible computers and mobile devices.
Print, Scan, Copy & Fax
The WorkForce Pro WF-3820 combines four essential office functions in one compact machine:
- ✔ Print – fast A4 black and colour business documents
- ✔ Scan – flatbed and multi-page ADF scanning
- ✔ Copy – convenient standalone colour and monochrome copying
- ✔ Fax – integrated office fax functionality
Epson 812 & 812XL DURABrite Ultra Ink
The Australian Epson WorkForce Pro WF-3820 uses the Epson 812 ink cartridge family, available in both Standard Capacity and High Capacity 812XL versions.
| Ink | Capacity | Approx. Yield |
| Epson 812 Black | Standard Capacity | 350 Pages |
| Epson 812 Cyan / Magenta / Yellow | Standard Capacity | 300 Pages Composite Colour |
| Epson 812XL Black | High Capacity | 1,100 Pages |
| Epson 812XL Cyan / Magenta / Yellow | High Capacity | 1,100 Pages Composite Colour |
Epson 812-series cartridges use DURABrite Ultra ink technology and are designed for sharp business text and professional colour documents.
For regular business printing, the higher-capacity 812XL cartridges provide more printing between cartridge replacements and can reduce the frequency of consumable changes.
Replaceable Maintenance Box
The WF-3820 uses the Epson C13T671500 Maintenance Box. The maintenance box is user-replaceable and is also shared with several other Epson WorkForce models, including the WF-3825, WF-4830 and WF-4835.
