Frequently Asked Questions

The name says "Cartridges" — how many are actually in this box?

One. The plural in this listing's title is a quirk of how the range is named; this product is a single compatible 106R01379 black cartridge at $71.15, rated at up to 4,000 pages. If you want multiples, this same line continues into 2, 3, 5 and 10 packs — but this box, honestly labelled here, holds exactly one cartridge.

Why does the part number sit in brackets at the end of the name?

So the listing answers both searches at once: the printer family up front, Xerox 3100, and the supply number, (106R01379), confirmed alongside it. That number is the identity that matters — it is the cartridge your machine was built around.

Which printers does this single cartridge serve?

The 3100MFP platform's two badges, the Phaser 3100MFP and the Phaser 3100MFP/S. Both nameplates specify 106R01379, so this cartridge suits either machine.

What should I expect from one cartridge's life?

Up to 4,000 pages at standard office coverage. On a multifunction machine, remember that copies and printed faxes spend the same toner as computer printouts — the total counts everything that left the machine on paper.

How does this single's price compare with the packs in its own line?

At $71.15 it is the line's starting point, about 1.78 cents per rated page. Its own siblings undercut it as quantity rises — the 2 pack brings the per-cartridge price to about $61.91 and the 10 pack to about $54.51 — but the single is the zero-commitment way in.

What backing does the bracket-line single carry?

Our 1-year warranty and 1-year free returns, with the details on the shipping and returns page, and support available Monday to Friday, 9 AM–5 PM CST.
