Frequently Asked Questions

Why is this set sold under four part numbers instead of a printer name?

Because the part numbers are the precise identifier. This set contains the black 310-5726, the cyan 310-5731, the magenta 310-5730 and the yellow 310-5729 — the high-yield cartridges, each rated at up to 4,000 pages, for Dell's 3000 and 3100 series color lasers. Printer model names overlap and get reused; a purchase order written against these four numbers can only ever be filled with these four cartridges.

Which number is which color?

310-5726 is black, 310-5731 is cyan, 310-5730 is magenta and 310-5729 is yellow. If you are matching against a stores list or an old invoice, those are the four lines to tick off. All four are the high-yield versions, rated at up to 4,000 pages apiece — not the shorter-life standard cartridges sold under different numbers.

What does the set cost per cartridge?

The set is $117.06, so about $29.27 per cartridge across the 310-5726, 310-5731, 310-5730 and 310-5729. Buying the four as a set keeps purchasing simple — one line, one delivery — and compatible pricing keeps the per-cartridge figure far below what the Dell-branded equivalents commanded.

Are these genuine Dell cartridges?

No. They are compatible cartridges from a third-party manufacturer, built to replace the Dell part numbers listed. The numbers, the fit and the 4,000-page ratings are the same as the originals; only the branding and the price differ. For a stock system keyed to Dell part numbers, nothing about your records has to change.

What cover backs the set?

Each cartridge carries a 1-year warranty and 1-year free returns, whether it is fitted on day one or held as shelf stock. Questions reach us Monday to Friday, 9 AM to 5 PM CST, and full terms are on our shipping & returns page.

Can I reorder just one number later?

Yes — the four cartridges are also sold individually under their own part numbers, which matters because they do not run out together. The black 310-5726 usually goes first in document-heavy use; the set gets your shelf fully stocked, and singles keep it topped up afterwards.
