Is this the right printer for you?

Who the Lexmark MX320/420 Series is actually for

Most equipment pages just tell you what a device does. Here's the honest version: when this machine is the right choice, when it's fine, and when you should look at something else. We offer equipment for every business need, but the right machine depends on your specific workflow.

Best fit

Pick this if...

  • You run a home office or a small team of 1-10 people printing mono only.
  • You print 500-3,500 pages a month — Lexmark's recommended volume is 500-4,000.
  • You need a desktop MFP that does print, copy, scan, fax without the workgroup price tag.
  • You want one of the smallest A4 mono MFPs Lexmark sells — under 17 inches in any direction.
  • You like Lexmark's drivers and security but only need entry-level volume.
Works fine

You'll be happy if...

  • You print up to 4,000 pages a month — top of recommended range; toner yields ~6,000-15,000 depending on cartridge tier.
  • You scan occasional multi-page documents — the 50-sheet reversing ADF works, just slower than single-pass duplex.
  • You want Wi-Fi — get the MX321adw or MX421adwe (wireless built in); MX321adn is wired only.
  • You're cross-shopping the MX520 — MX320/420 is the entry tier, MX520 jumps to 46 ppm and single-pass DADF.
Look elsewhere

Skip this if...

  • You need color. This is mono only — get a CX310/410 or CX-series MFP instead.
  • You print more than 4,000 pages a month — at that volume look at MX520 or MX620.
  • You scan two-sided originals constantly — reversing ADF is slow vs. single-pass DADF on MX520+.
  • You need a big touchscreen for kiosk workflows — MX321 has a 2.8-inch monochrome display; the 4.3-inch color is on the MX421 only.
  • You need 50+ ppm for short urgent jobs — MX320/420 caps at 38 ppm.
Full specifications

Every spec, no guessing

The Lexmark MX320/420 series (MX321, MX421) is the entry-tier desktop mono laser MFP for home offices and small teams of 1-10 that print 500-3,500 pages a month and want one machine that does print/copy/scan/fax without paying for workgroup hardware. It prints and copies at up to 38 ppm, scans through a 50-sheet reversing ADF, and is rated for a 60,000-page monthly duty cycle (Lexmark recommends 500-4,000/month). Standard input is 350 sheets across the 250-sheet tray and 100-sheet multipurpose feeder, expandable to 900 with an optional 550-sheet tray. MX321 ships with a 2.8-inch monochrome display; MX421 steps up to a 4.3-inch e-Task color touchscreen. Wireless is built into the MX321adw and MX421adwe; the MX321adn is wired only (Gigabit Ethernet + USB 2.0). The thing buyers regret: assuming the small ADF can scan a 20-page contract quickly. The reversing ADF works but is meaningfully slower than the single-pass DADF on the MX520+. For pure desktop print at 38 ppm with occasional scan/fax in a sub-17-inch footprint, the MX320/420 series is the entry-volume Lexmark mono MFP.
