ProXpress M3870FW

The ProXpress M3870FW is the most connected M3870: fax for the phone line, wireless for the network, and the fast mono engine both feed. Offices that buy the fully-loaded variant tend to use it hard, which is exactly when compatible toner pays off most — the 15,000-page MLT-D203U brings the per-page cost down to where high-volume fax-and-print workflows stay sane. All D203 yields fit; ours cost far less than OEM.

Frequently Asked Questions

Is the toner setup on the M3870FW the same as the M3870FD?

Yes - both use MLT-D203S/L/E/U. Choose fax-friendly settings (draft mode for incoming faxes) the same way on either model.

The M3870FW sits in our warehouse office far from supplies - which MLT-D203 size minimizes restock trips?

The MLT-D203U - the ultra-high yield means the fewest trips per year. Pair it with low-toner email alerts so someone brings a replacement before the warehouse printer goes dark.

Our M3870FW prints faded with a compatible MLT-D203 but fine with OEM - why?

Compatible toner formulations vary, and some lay down lighter coverage than OEM. If the compatible consistently prints faded while OEM looks right, that batch's toner density is the issue - switch brands or go OEM for that printer.
