ProXpress M3320DN

With built-in duplexing and network connectivity, the ProXpress M3320DN is the M3320 configured for shared office use, so its toner math changes: shared machines burn through cartridges faster, which makes the high-yield MLT-D203U (15,000 pages) the economical pick over the standard D203S. This mono laser MFP runs the full MLT-D203 range — D203S (3K), D203L (5K), D203E (10K), D203U (15K) — and our compatible cartridges cover all four yields.

Frequently Asked Questions

Does the duplex unit on the M3320DN change which MLT-D203 cartridge I should buy?

No - duplexing affects paper, not toner chemistry. But duplex offices often print more total sides, so the higher-yield MLT-D203L, E or U cartridges make sense to cut down on changeovers.

Can I check MLT-D203 toner levels on the M3320DN remotely?

Yes - the network interface lets you view toner status from any browser on the network. That makes it easy to reorder the right MLT-D203 size before the printer runs dry.

The M3320DN's toner gauge dropped from half to empty overnight - is the sensor broken?

Probably not - gauges estimate from page counts and can jump when the cartridge crosses a threshold. If prints still look good, keep printing and have a replacement MLT-D203 ready; the gauge is a guide, not a precise meter.
