Lexmark MS521DN A4 B&W Heavy Duty Mono Laser Duplex Printer 44PPM [36S0314]

The Lexmark MS521dn A4 Mono Laser Printer [36S0314] is a robust, high-performance black-and-white workgroup printer designed for businesses that need fast, dependable and economical document printing. Delivering print speeds of up to 44 pages per minute, automatic duplex printing, Gigabit Ethernet networking and support for ultra-high-yield toner cartridges, the MS521dn is built for demanding office environments with regular high-volume printing requirements.

With a recommended monthly print volume of 2,000 to 15,000 pages and a maximum monthly duty cycle of up to 120,000 pages, the MS521dn is significantly more capable than a typical entry-level desktop laser printer. Its combination of durable construction, expandable paper handling and toner capacities up to 25,000 pages makes it particularly suitable for busy offices, warehouses, accounting departments, schools and medium-sized workgroups.

Fast 44PPM Business Printing

The Lexmark MS521dn delivers black-and-white print speeds of up to 44 pages per minute, making it well suited to workgroups that regularly produce reports, invoices, correspondence, picking slips, forms and other business documents.

With first-page output in as fast as approximately 6 seconds, the printer is also responsive for shorter print jobs where users do not want to wait for a high-volume office printer to get started.

Built for Demanding Workgroups

The MS521dn is designed for medium-sized workgroups rather than occasional home printing. Lexmark recommends a monthly print volume between approximately 2,000 and 15,000 pages, making it an excellent option for offices that require consistent daily mono printing.

Its maximum monthly duty cycle of up to 120,000 pages demonstrates the substantial mechanical capacity of the printer, although the recommended monthly range should be used as the more practical guide for sustained everyday operation.

Automatic Duplex Printing

Built-in automatic two-sided printing allows the MS521dn to print on both sides of supported paper without requiring pages to be manually turned over.

This helps reduce paper consumption while producing professional double-sided reports, contracts, manuals and other business documents.

Gigabit Ethernet Networking

The MS521dn includes integrated Gigabit Ethernet (10/100/1000), allowing the printer to be shared across a business network by multiple users.

A Hi-Speed USB 2.0 Type-B connection is also provided for direct connection to a compatible computer.

Please note: Wi-Fi is not built into the standard MS521dn configuration. Businesses requiring wireless connectivity should use a compatible network configuration or supported optional wireless solution.

Flexible Paper Handling

The MS521dn provides a useful combination of standard and multipurpose paper handling for everyday office requirements.

The 100-sheet multipurpose feeder is particularly useful for envelopes, labels, speciality media and smaller print jobs without having to unload the main paper tray.

Wide Range of Supported Media

The Lexmark MS521dn supports a broad selection of standard business paper sizes including:

• A4
• A5
• A6
• Letter
• Legal
• Executive
• Statement
• Folio
• Oficio
• JIS B5
• DL Envelopes
• Other Supported Envelope & Universal Sizes

High-Yield Toner Options

One of the major advantages of the MS521dn for higher-volume users is its support for a range of toner capacities. Depending on the applicable cartridge type and Australian/New Zealand regional supply, the printer supports toner yields ranging from approximately 6,000 pages up to 25,000 pages.

Toner yields are declared in accordance with ISO/IEC 19752. Actual cartridge yield varies according to page coverage, print settings, document type and usage conditions. Lexmark toner cartridges are region-coded, so the correct Australia/New Zealand cartridge should be selected.

5,000-Page Starter Toner Included

The Lexmark MS521dn is supplied with a starter Return Program toner cartridge rated for up to approximately 5,000 pages, providing substantial initial printing capacity straight from the box.

This is significantly more starter toner than is commonly supplied with many entry-level laser printers and makes the MS521dn particularly attractive for businesses that need to begin higher-volume printing immediately.

Long-Life 60,000-Page Imaging Unit

The MS521dn uses a separate imaging unit with an estimated life of up to approximately 60,000 pages under Lexmark's specified usage conditions.

Separating the toner cartridge from the imaging unit allows toner to be replaced independently while the longer-life imaging component remains in service until replacement is required.

Business-Class Security

The MS521dn incorporates Lexmark's enterprise-oriented approach to print security, helping businesses protect documents, devices and network access.

This makes the printer particularly suitable for networked office environments where device security and controlled access are more important than on a basic personal desktop printer.

Product Specifications

Australian / New Zealand Toner Compatibility

Lexmark toner cartridges are region-specific. For Australia and New Zealand, customers should use the appropriate ANZ-region cartridge for the MS521dn.

The printer supports several toner capacity options, allowing businesses to choose between lower upfront consumable cost and higher-yield cartridges offering fewer replacements and potentially lower cost per page.

Important: Always verify the regional toner part number before ordering. Toner cartridges intended for another geographical region may not operate in an Australian MS521dn.

At approximately 14.1kg, it has the robust construction expected from a printer designed for sustained business workloads.

Why Choose the Lexmark MS521dn?
