Is this the right printer for you?

Who the Lexmark MS420 Series is actually for

Most printer pages just tell you what a printer 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 sell a lot of these for a reason, but the reason is not "every office."

Best fit

Pick this if...

  • Pick this if you print 1,500-5,000 mono pages a month and want 42 ppm throughput.
  • Pick this if you already have an MFP and just want a fast dedicated print engine alongside it.
  • Pick this if 6.25-second first-page-out matters for ad-hoc jobs.
  • Pick this if expandable input to 900 sheets would let you skip refills.
  • Pick this if Gigabit Ethernet and standard duplex cover your needs.
Works fine

You'll be happy if...

  • It's fine if your real volume is closer to 800-1,500 pages a month — you have headroom.
  • It's fine if you only need wireless on the dw variant rather than every model.
  • It's fine if you live with the basic two-line LCD instead of a touchscreen.
  • It's fine if you print mostly text and don't need beyond 1,200 dpi.
  • It's fine if you connect via USB and don't put it on the network.
Look elsewhere

Skip this if...

  • Skip this if you need scan, copy, or fax — the MX420 is the MFP version.
  • Skip this if you need color — this is mono only.
  • Skip this if your monthly volume is under 500 pages — overkill.
  • Skip this if you need a color touchscreen interface.
  • Skip this if you print legal-plus or A3 — only goes to legal.
Full specifications

Every spec, no guessing

The Lexmark MS420 Series (MS421dn) is a single-function monochrome laser sized for small offices that print 1,500-5,000 pages a month and want speed without paying for a workgroup machine. It runs 42 ppm at 1,200 x 1,200 dpi (with a 2,400 IQ mode for sharp text), first page out in 6.25 seconds, integrated duplex, a 350-sheet input tray expandable to 900 sheets, and a 100,000-page rated monthly duty cycle. Power is a 1 GHz dual-core with 512 MB RAM, connectivity is USB 2.0 and Gigabit Ethernet (Wi-Fi only on the dw variant). The honest gotcha buyers run into: it's a print-only device with a tiny two-line display, so if you want any kind of touchscreen workflow or scan/copy/fax, get the MX420 instead. And if your monthly volume is under 800 pages, you're paying for a 100K duty cycle you'll never touch — a smaller Lexmark or Brother saves real money up front.

Supplies & consumables

Toner, yields, and what to actually reorder

The #1 question we get on this printer is "which toner do I buy?" Short answer: you have two cartridge options and a drum. Standard yield TN830 covers roughly 1,200 pages. High yield TN830XL covers roughly 4,500 pages and is the better value for most offices. Pick XL unless you print very little.

The drum unit (DR810) is separate and usually lasts 15,000 to 30,000 pages before it needs replacing. At a typical small office volume, expect to change it once every 2 to 4 years.

If you lease this printer through us, toner and drum are included. You never pay for supplies separately. That's usually the better deal once you add up real costs over 3 years.

FAQ

Lexmark MS420 Series, common questions

The questions we get asked most often on this model. If yours isn't here, call (706) 561-0075 and get an answer in about 30 seconds.

Yes, the Lexmark MS420 Series ships with a starter toner cartridge that yields approximately 6,000 pages. Replacement options include high-yield (15,000 pages) and extra high-yield (20,000 pages) cartridges. When you lease through us with toner included, you never pay for toner separately.
The Lexmark MS420 Series is a monochrome, single-function printer designed for small offices with a monthly volume of 1,500-5,000 pages, offering 42 ppm and a 100,000-page duty cycle. In contrast, the Lexmark CS960 Series is a floor-standing A3 color laser printer built for workgroups of 30-100 people, printing 55 ppm in both black and color with a 270,000-page duty cycle. The CS960 Series also features a 4.3-inch touchscreen, expandable paper capacity up to 4,750 sheets, and supports A3 printing, making it ideal for larger offices needing high-volume color output.
The Lexmark MS420 Series is well-suited for small businesses with a monthly print volume of 1,500-5,000 pages, offering a fast 42 ppm speed and a robust 100,000-page duty cycle. However, if your volume is under 800 pages, a smaller printer may be more cost-effective. For businesses needing color or multifunction capabilities, consider stepping up to a commercial option like the Lexmark CS632dwe or MX420 series.
No, the Lexmark MS420 Series is a monochrome-only printer. For color printing, consider alternatives like the Lexmark CS632dwe, CS960 Series, or MX420 series.
