ProXpress M3870

Adding integrated fax to the fast M3820-class engine, the ProXpress M3870 serves workgroups that still route documents by phone line. It's a toner-hungry combination — high print speed plus automatic fax reception — so this is firmly MLT-D203U (15,000-page) territory for most buyers. The D203S (3K), D203L (5K) and D203E (10K) also fit. Our compatible MLT-D203 range means you never pay OEM prices for that appetite.

Frequently Asked Questions

The M3870 is a faster engine than the M3820 - should I buy bigger MLT-D203 cartridges for it?

Only if your page volume is higher. Speed does not change per-page toner use, so match the cartridge size (S, L, E or U) to monthly pages, not to the ppm rating.

My M3870 prints a repeating dot down the page - new MLT-D203 or something else?

A repeating mark at regular intervals usually indicates a damaged drum or roller inside the cartridge. Since the MLT-D203 is an all-in-one cartridge, replacing it with a fresh one resolves the defect.

Our office goes through an MLT-D203 every month on the M3870 - is there a recycling program that picks up?

Many toner recyclers and office-supply programs offer free pickup for business volumes - a cartridge a month easily qualifies. Ask your supplier about a take-back program instead of trashing them.
