The Epson WorkForce Pro WF-M5399 Monochrome Printer (model C11CK77201) is a high-performance business inkjet engineered for reliability in busy workgroups and offices. Powered by Epson’s PrecisionCore Heat-Free technology, it delivers fast, consistent output with virtually no warmup time and low power consumption — making it a smarter, more cost-effective alternative to traditional laser printers.
Print at speed. The WF-M5399 produces sharp, professional monochrome documents at up to 25 ISO ppm with automatic duplex printing at 16 ISO ppm. First-page-out time is just 4.8 seconds, so your team never waits. Maximum print resolution reaches 1200 × 2400 dpi for crisp text and detailed graphics.
Go longer between ink changes. High-capacity Epson DURABrite Ultra Replaceable Ink Packs yield up to 40,000 ISO pages per black ink pack, dramatically reducing interventions and lowering your cost per page — save up to 50% compared to monochrome laser toner.
Handle serious paper volume. The standard 330-sheet capacity (250-sheet cassette plus 80-sheet rear tray) expands to 1,830 sheets with up to three optional 500-sheet cassette trays. A manual feed slot accepts paper sizes from 3.5″ × 5″ up to 8.5″ × 236″ banners. The recommended monthly page volume is 5,000 pages, with a maximum monthly duty cycle of 70,000.
Connect your way. Built-in Wi-Fi (802.11 a/b/g/n/ac), Wi-Fi Direct, Gigabit Ethernet, and Hi-Speed USB 2.0 give you flexible network and direct-connect options. Supports Apple AirPrint, Mopria Print Service, Epson Connect (Email Print and Remote Print), and the Epson Smart Panel app.
Enterprise-ready features. Full PCL 5/6 and PostScript 3 emulation for seamless integration with existing print environments. Security features include PIN-based job release, user access control, SSL/TLS encryption, and IPsec. Compatible with the Epson Solutions Suite for remote device management and diagnostics.
