Overview

The Epson WorkForce Pro WF-3730 is a four-function inkjet all-in-one built around Epson's Precision Core printhead technology — a piezoelectric inkjet architecture that delivers 20 ISO ppm black and 10 ISO ppm color output. Those numbers are measured against the ISO/IEC 24734 standard, which means they reflect continuous multi-page print jobs rather than single-page best-case figures. The 500-sheet paper capacity is split across two trays, enabling simultaneous loading of different media types — a meaningful operational feature for offices that regularly switch between letter, legal, and envelopes. Connectivity covers the full range: USB, 10/100 Ethernet, 802.11 b/g/n Wi-Fi, Wi-Fi Direct, and NFC, giving it broad compatibility with existing network infrastructure and mobile devices.

The WF-3730 is built for home offices and small workgroups where a single device needs to handle daily print, copy, scan, and fax duties without the toner cost structure of a color laser. Epson's published cost-per-page comparison — 30% lower than comparable color laser — is the central value argument, and it holds up in practice over high-volume use. The built-in fax is a genuine differentiator for offices that still operate fax-dependent workflows. The enforced genuine-cartridge requirement narrows the consumable options, but for users committed to staying within the Epson ecosystem, the WF-3730 delivers a reliable, full-featured output platform at a lower total cost of ownership than most laser alternatives in its tier.

Key Features

This printer is designed for use with Epson cartridges only, not third party cartridges or ink. Cartridges described as Compatible, Remanufactured, refilled or refillable may not work properly or at all. See product description for more details.

Pros & Cons

👍 Pros

  • Precision Core printhead delivers 20 ISO ppm black output, matching or exceeding many entry-level laser printers at this price point.
  • Dual-tray 500-sheet capacity significantly reduces paper-reload interruptions compared to single-tray printers in its class.
  • Documented 30% lower cost-per-page versus comparable color laser models — a measurable long-term operating cost advantage.
  • Full connectivity stack — USB, Ethernet, Wi-Fi, Wi-Fi Direct, and NFC — covers virtually every connection scenario without adapters.
  • Genuine all-in-one functionality (print, copy, scan, fax) eliminates the need for separate office peripherals.

👎 Cons

  • Locked to genuine Epson cartridges only — third-party ink is not supported, which removes the option to reduce consumable costs through aftermarket supplies.
  • Color output at 10 ISO ppm is half the black speed, creating a meaningful throughput gap on color-heavy print jobs.
  • No onboard cache memory listed in specifications, which can cause print queue stalls on complex multi-page documents sent from multiple network users simultaneously.
  • 802.11 b/g/n wireless does not support the 5 GHz band, limiting connection stability in congested 2.4 GHz environments.

Frequently Asked Questions

The WF-3730 prints at 20 ISO ppm black and 10 ISO ppm color. Those are ISO-standard measurements — real-world throughput on mixed document jobs runs slightly lower, but the Precision Core printhead architecture closes the gap with entry-level color laser on most office workloads.
Yes. The WF-3730 uses dual paper trays, so you can load standard letter in one tray and legal, photo paper, or envelopes in the other simultaneously — switching between them without manual reloading.
The printer supports 802.11 b/g/n Wi-Fi, Wi-Fi Direct (for direct device connections without a router), wired Ethernet at 10/100 Mbps, Hi-Speed USB, and NFC for tap-to-print from compatible mobile devices.
No. Epson has engineered the WF-3730 to function exclusively with genuine Epson cartridges. Third-party, remanufactured, or refilled cartridges may trigger errors or fail to print entirely. This is a documented hardware-level restriction, not just a software warning.
It's a full four-function all-in-one: print, copy, scan, and fax. The fax capability is built-in, making it practical as a standalone office machine without additional hardware.
