Frequently Asked Questions

How do we put a defensible per-page cost on our 3100cn's toner?

Work from the set price and the ratings: $117.06 buys four cartridges — black 310-5726, cyan 310-5731, magenta 310-5730 and yellow 310-5729 — each rated at up to 4,000 pages, so about $29.27 a cartridge and roughly 0.73 cents per page across the set's 16,000 pages of capacity. If your department charges printing back to projects, that single figure is the one to use, and it is far below what the Dell-branded cartridges would have produced in the same calculation.

Which cartridges does the 3100cn take?

The high-yield set: 310-5726 in black, 310-5731 in cyan, 310-5730 in magenta and 310-5729 in yellow, 4,000 pages each. Matching by part number rather than by model name is the reliable way to order for this range, because Dell sold several closely related machines in the same period.

Do the four cartridges empty together on a networked printer?

Rarely. A networked 3100cn mostly prints documents from many users, and that traffic is overwhelmingly black text — so the 310-5726 goes first, sometimes long before the colors. The set means the cyan, magenta and yellow are already on site when their turn comes, rather than being ordered one at a time under pressure.

Is this a genuine Dell set?

No. It is a compatible set from a third-party manufacturer, built to the Dell specification — same part numbers, same fit, same 4,000-page ratings as the originals. What changes is the price and the badge, not the cartridges your printer was designed around.

What cover comes with the set?

A 1-year warranty and 1-year free returns on each cartridge, with support Monday to Friday, 9 AM to 5 PM CST. Full terms are on our shipping & returns page.

How quickly can a replacement reach us?

Orders are dispatched from our warehouses in IL, PA, GA or CA, so delivery is a domestic trip rather than an import wait. For a printer the whole office depends on, the practical advice is to reorder when the first low-toner warning appears — a 4,000-page cartridge gives you a comfortable window rather than an emergency.
