Lexmark MS621dn: wired mono printing with a larger included drawer review

A larger main drawer is already included

The Lexmark MS621dn is an earlier reference for a wired workgroup that needs monochrome output and a substantial supplied main paper stack. The included 550-sheet drawer and 100-sheet multipurpose feeder distinguish it from smaller 250-sheet-drawer variants. Wireless remains optional, and the larger maximum input still requires separately installed hardware.

This description covers exact US part 36S0400, marked discontinued by Lexmark. Confirm the regional unit, accessories, consumables and compatible software for a real offer. The original specifications establish the configuration rather than stock, warranty entitlement or the condition of an individual machine. Similar speed or screen size does not make a nearby model's supplied tray or radio part of this package.

Understand the ordinary workload and print modes

Lexmark recommends 2,000–20,000 printed pages monthly and separately lists a 175,000-page maximum duty cycle. Use the recommended range to judge routine work. The duty ceiling is a different comparison measure, and neither it nor the engine's speed removes the need to manage paper, toner and the pattern of jobs.

The declared maximum is 50 one-sided Letter pages per minute in black. Automatic print duplex is separately rated at 24 Letter sides per minute. These are maker declarations, not measured results from this article. Letter, Legal and A4 have positive support in the normal input paths and automatic duplex. The guide's duplex paper-weight range is 60–90 gsm, narrower than the multipurpose feeder's overall 60–216-gsm range, so heavy-sheet acceptance does not guarantee two-sided suitability.

Use the included stack and configure any expansion

Standard input is 650 sheets on the specified 20-pound or 75-gsm basis: 550 in the main drawer and 100 in the multipurpose feeder. Both support the ordinary Letter, Legal and A4 sizes. Keeping envelopes or alternate stock in the multipurpose input changes what is loaded for an ordinary document run. Envelopes follow the separate one-sided routine with size and type set correctly at the printer and in software.

The documented maximum is 2,300 sheets with optional drawers. Check the actual supported combination, physical installation and any stand requirements before depending on that expanded configuration. The original guide instructs users to make added hardware available in the driver. The included 550-sheet main drawer is useful on its own, but catalogue expansion is not a promise about the offered package.

Wired sharing and the separate front USB input

Standard interfaces are USB Type-B for a computer and gigabit Ethernet for shared networking. A separate front Type-A port supports the documented flash-drive printing routine. Keep those roles distinct when choosing a cable or a walk-up workflow. The exact US page lists MarkNet N8370 and N8372 wireless hardware as options rather than included radios.

AirPrint and Mopria operate through suitable shared networking, including an Ethernet printer reached by a mobile device on office Wi-Fi. A direct USB computer alone does not supply that shared path. Confirm current software compatibility. The guide describes confidential jobs held in memory and a disk-dependent invalid-PIN setting, but verify the exact submission and release procedure before treating protected collection as a purchase requirement.

Monochrome hardware and regional supplies

The 2.4-inch color LCD controls a monochrome print-only machine. Lexmark's exact support classification confirms no document scanner, copier or fax hardware. Generic print-and-scan software names do not change that physical scope. Choose a multifunction device if staff need to capture paper originals at the machine.

Supplied toner is declared at 6,000 standard pages under ISO/IEC 19752. Exact US replacements include 56F1U00 at 25,000 pages, 56F1X00 at 20,000, 56F1H00 at 15,000 and 56F1000 at 6,000, with regular 56F0UA0 also rated at 25,000. The imaging unit is separate and has its own declared estimate and use conditions. Match region and Return Program terms rather than calculating current running cost from yield alone.

The body measures 15.7 inches wide, 14.7 deep and 11.9 high at 34.8 pounds before access clearance. Check the actual electrical label and cord. Choose this configuration when the supplied main stack and wired mono routine fit, comparing optional wireless and expansion as separate hardware decisions.
