Frequently Asked Questions

How do you prove it is the yellow that is out — and not one of the other colors?

Print a single full page of solid yellow from the printer's test patterns. Documents can argue with you, because every color on them is a mixture; a pure yellow page cannot. If that sheet comes out pale, patchy or streaked, the yellow cartridge — the 106R01079 — is spent, full stop. If the solid yellow is rich and even, the yellow is innocent and your color problem lives in a different cartridge. Two minutes with one test sheet ends the debate that mixed documents can sustain for weeks.

Two symptoms appeared at once: greens turned blue and oranges turned pinkish-red. One cause or two?

One. Both colors are built with yellow. Green is cyan plus yellow — lose the yellow and it falls to blue. Orange is magenta plus yellow — lose the yellow and it falls toward pink and red. When two seemingly unrelated colors drift in the same week and both mixtures share one ingredient, that ingredient is the story. The two-symptom pattern is the most reliable no-tools diagnosis of a dead yellow this platform offers.

Why did the visible shift arrive before any low-toner warning seemed urgent?

Because yellow fails gradually and hides while doing it. Its pigment is the lightest in the machine, so a slow decline reads as "the colors look a bit cold lately" long before it reads as a fault — and a warning level that still says a few percent remaining can already be too weak to hold greens together. Trust the test page over the percentage: the solid yellow sheet shows the cartridge's real condition today, not its estimated one.

A new cartridge is in and the yellow still prints pale — what now?

First, take the cartridge back out and refit it slowly and firmly — a unit that is not fully seated can under-deliver. Give it a gentle side-to-side rock before reinstalling, as the packaging directs, to settle the toner evenly. Then print the solid yellow test page again rather than judging by a document. If a correctly seated cartridge still cannot lay down an even yellow field, that is exactly what the warranty below exists for.

What is the running cost of this cartridge?

It is rated up to 18,000 pages, and at $92.31 the yellow works out to about 0.51 cents per standard page — the reason the high-yield version is the default choice for a machine this size. Photographs and full-color graphics will draw it down faster than the rating's assumptions; light office color will draw it down slower.

What cover comes with it?

A 1-year warranty and free returns for a full year, as set out on our shipping & returns page. Shipments leave warehouses in IL, PA, GA and CA, help runs Monday to Friday, 9 AM to 5 PM CST, and the platform's remaining supplies are collected on the Xerox page.
