Frequently Asked Questions

We are reordering from an old invoice — is this the same set we bought before?

If your invoice lists the four part numbers 310-5726, 310-5731, 310-5730 and 310-5729, yes — this is that set: the black, cyan, magenta and yellow high-yield cartridges for the Dell 3000 family, each rated at up to 4,000 pages. Matching on part numbers is the safest way to reorder, because the same set appears under more than one listing name on our site and the numbers never change.

Why does this set show up under different listing names?

Because buyers search differently — some by printer model, some by part number. The listings describe the same four cartridges: 310-5726 black, 310-5731 cyan, 310-5730 magenta and 310-5729 yellow, at the same $117.06 and the same ratings. Whichever listing you order from, the same set is picked and shipped.

What is the price breakdown?

$117.06 for four cartridges, about $29.27 each, with each cartridge rated at up to 4,000 pages. Across the set that is 16,000 pages of cartridge capacity at roughly 0.73 cents per page — the figure to compare against the Dell-branded originals, which for this discontinued range are both pricier and harder to find.

Are these genuine Dell cartridges?

No — this is a compatible set, made by a third-party manufacturer to the Dell specification. The part numbers it replaces are Dell's (310-5726, 310-5731, 310-5730, 310-5729), so your invoice history and stock records line up exactly; the cartridges themselves are compatible rather than Dell-branded.

What cover does the set carry?

A 1-year warranty and 1-year free returns on every cartridge in the set. If one arrives faulty or fails early, it comes back to us — reach us Monday to Friday, 9 AM to 5 PM CST, with the full terms on our shipping & returns page.

Can we buy the cartridges individually next time?

Yes — each of the four is sold singly under its own part number, which is the practical way to top up because they deplete at different rates. The black 310-5726 normally goes first; the colors follow in their own time. The set is for a full restock; singles are for maintenance.
