ProXpress M3370FW

The ProXpress M3370FW combines fax with wireless networking, the configuration for offices that want every function available to every device without cables. Underneath it's the same Samsung-engine mono platform as the rest of the M3370 line, so consumables are the familiar MLT-D203 set. Wireless placement often means the printer sits far from the supply closet — another argument for the long-life D203E (10K) or D203U (15K). Our compatible MLT-D203 cartridges ship in all four yields.

Frequently Asked Questions

We are replacing an M3370FD with an M3370FW - does our MLT-D203 stock transfer?

Yes - both models use the MLT-D203S/L/E/U family, so your existing stock moves over directly. The FW trades the FD's configuration for wireless and fax; cartridges are identical.

Reception's M3370FW gets light but unpredictable use - S, L, E or U?

Go with the MLT-D203L. The S might die at an awkward moment under a surprise burst, while E or U ties up money in toner a reception printer may take a year to use. L is the safe middle.

A compatible MLT-D203 costs much less for our M3370FW - what is the real trade-off?

Upfront savings versus consistency: compatibles can print perfectly well, but quality varies by batch and firmware updates can occasionally break their chips. For a reception printer where reliability matters, weigh that risk against the price gap.
