Frequently Asked Questions

The cartridge I pulled from our 5110 is marked 310-7891 — is this listing that same cartridge?

Yes. The number in parentheses in this listing's title, 310-7891, is the Dell part number for the cyan cartridge used by the Dell 5110. If the cartridge you removed is stamped 310-7891, this is the matching replacement — checking the part number on the old cartridge is the most reliable way to order the right cyan unit without guesswork.

How many pages does this cartridge cover?

It is rated at up to 12,000 pages, based on the standard 5% coverage measurement used across the toner industry. Offices printing mostly documents with modest color will land close to that figure; heavy photo and graphics work will use the cyan supply sooner.

What is the per-page cost at this price?

At $69.55 and up to 12,000 pages, cyan works out to approximately 0.58 cents per page. That makes it easy to budget color printing for a 5110: track your monthly color page count and you can predict your cyan spend within a few dollars.

When should I order the next one?

A good rule is to reorder when the printer first reports low cyan rather than waiting for it to run dry — with up to 12,000 pages per cartridge, most offices only face this decision a few times a year. Keeping one spare on the shelf means a faded-print morning never turns into a stopped workday.

Is this a genuine Dell product?

This is a compatible cartridge, not a Dell original. It is built to the 310-7891 specification for the Dell 5110 and delivers comparable color and yield, backed by a one-year warranty. If anything goes wrong, our shipping & returns policy gives you one-year free returns.

Where does it ship from, and when is support available?

Your cartridge ships from the nearest of our Illinois, Pennsylvania, Georgia and California warehouses. Our support team is on hand Monday through Friday, 9 AM to 5 PM CST for order or product questions, and the rest of our Dell range lives on the Dell toner page.
