Frequently Asked Questions

Our greens have started printing blue — what is going on?

That shift points at the yellow bay. Green on a colour laser is a mixture: the machine puts cyan and yellow down together and your eye reads the blend as green. When the yellow cartridge gets low, the cyan half keeps printing at full strength while the yellow contribution thins out, and every green on the page slides toward blue. The same shortage cools oranges down toward red, because orange is magenta plus yellow with the yellow going missing. If your Phaser 6510 has started turning grass into water, the cartridge in this listing — the 106R03479 yellow — is the one running dry.

Yellow is almost invisible on white paper, so how do I check whether it is really the problem?

You cannot judge yellow by looking at a finished page the way you can with the other colours — pale yellow on white is nearly impossible to see, which is exactly why a yellow shortage hides for so long. Use the printer instead: print the colour test or demo page from the control panel, where each toner lays down its own solid band. A yellow band that comes out streaky, patchy or missing altogether confirms the diagnosis without guesswork. The supplies status screen gives you the same answer in numbers. Check one of those two before you order, and you will not replace the wrong colour.

How long will a 2,400-page yellow cartridge last on a desktop printer?

Yellow rated at 2,400 pages works out to about 1.04 cents per page at this listing's $24.96 price, under the standard 5% coverage test the whole industry uses. On a personal or two-person desktop machine printing a few dozen colour pages a week, that rating commonly stretches across most of a year. Busier desks that run colour handouts daily will land closer to a few months. Either way, yellow on a lightly used machine usually outlasts expectations — and then surprises people, because of the invisibility problem covered above.

Why did the yellow seem to run out all at once, with no warning signs?

Because the usual warning signs are visual, and yellow does not give you any. A fading cyan or magenta announces itself in washed-out blues and oranges-turned-red long before the cartridge is truly empty; a fading yellow only shows up second-hand, inside mixtures like green and orange, and most people blame the other colour first. By the time the shift is obvious the cartridge is nearly spent. The supplies counter is the honest signal here — when it says the 106R03479 is low, believe it, and have the replacement on hand rather than waiting for the prints to prove it.

Is this the right yellow for my printer?

This listing is the yellow cartridge coded 106R03479, made for two machines: the WorkCentre 6515 and the Phaser 6510 named in the title. The two share the same engine family and the same set of colour bays, so a spare bought for one is a spare for the other. Match the code on your empty cartridge's label against 106R03479 before ordering — colour names alone can mislead, because several Xerox desktop models use similar-looking yellow units with different codes.

What cover and delivery come with this cartridge?

Every cartridge ships with a 1-year warranty and 1-year free returns, so a unit that misbehaves early goes back for a replacement or a refund instead of becoming your loss. Orders leave from whichever of our warehouses — IL, PA, GA or CA — gives the shortest route to your door, and our support team answers Monday to Friday, 9 AM to 5 PM CST if you would rather talk to a person. Delivery timelines, costs and the full returns procedure are set out on our shipping & returns page.

About This Yellow Cartridge for the Phaser 6510

This is one compatible yellow toner cartridge — the 106R03479 — built for the Phaser 6510 desktop colour printer and rated at 2,400 pages. Yellow is the quietest worker in a colour machine: it warms every skin tone, builds every green and orange, and gives up so gradually that its decline is usually misread as a cyan problem. Keeping a genuine spare on the shelf matters more with this colour than with any other, precisely because the page will not warn you in time. The complete Xerox toner range is on the site when the other bays need attention, and every unit travels with the 1-year warranty and 1-year free returns described above, shipped from IL, PA, GA or CA.
