Frequently Asked Questions

Our reds have started printing orange. Is the magenta cartridge the reason?

Very often, yes. On this platform red is not a toner of its own — the printer lays magenta and yellow side by side to build it, so when the magenta runs low the mix starves on one side and reds slide toward orange, brick and brown, while pinks wash out to peach. Black text stays perfect because it comes from a separate cartridge, which is why a page can look half right: sharp words, wrong colours. If your Phaser 6510 is doing that, the 106R03691 magenta is the bay to check before suspecting the machine itself.

How long will a 4,300-page magenta actually last us?

The 106R03691 in this listing is the high-capacity fill, rated at up to 4,300 pages at the standard 5% coverage measure. Translated into office time: a 6510 that prints around 300 colour pages a month can run well over a year on one magenta, because only the colour pages touch it — the black-and-white jobs in between draw nothing from this cartridge. Heavy coverage shortens the run, since a full-page colour flyer can use several times the toner of a letter carrying a red logo, so treat 4,300 as the yardstick it is and the changeover as a rare event rather than a monthly chore.

The printer says magenta is low. Can we keep printing?

You can, for a while — the warning is a forecast, not a lockout. What changes first is the colour itself: reds lose depth, skin tones flatten and charts stop matching what you approved on screen, sometimes pages before the cartridge truly empties. For internal drafts that hardly matters; for anything a customer will see, it is the expensive way to save a day. The sensible habit is to order the replacement when the warning appears and swap the 106R03691 in when the colour shift shows, keeping the part-used unit as an emergency spare.

What does this cartridge work out to per page?

At $26.02 for a fill rated at up to 4,300 pages, the 106R03691 runs at roughly 0.61 cents per colour page. That arithmetic is what makes the high-capacity fill the quiet bargain of this platform: the outlay on the day is one modest cartridge price, and the cost is then spread across thousands of pages before you have to think about magenta again. If your 6510 prints colour only occasionally, the same figure still holds — the pages simply arrive more slowly.

Which printers does this magenta fit?

The 106R03691 fits two machines that share the same colour engine: the Phaser 6510 printer and the WorkCentre 6515 multifunction, so a single spare magenta covers either if your office runs both. The check that removes all doubt takes ten seconds: pull the cartridge you are replacing and read its label — if it says 106R03691, this listing is the like-for-like swap. Order by that code rather than by colour alone, because each colour in this family has its own part number.

If we order a spare ahead, what cover and delivery come with it?

Every 106R03691 we sell is covered by a 1-year warranty and 1-year free returns, so a spare that turns out faulty is replaced or refunded rather than argued over — and an unopened spare keeps fine in its sealed packaging in a cool, dry cupboard. Orders leave from whichever of our four warehouses — Illinois, Pennsylvania, Georgia or California — is closest to you; the full postage and returns detail is on our shipping & returns page. If you want a person to confirm the code before you order, support answers Monday to Friday, 9 AM to 5 PM CST.

About This Phaser 6510 Magenta Toner Cartridge

This listing is a single compatible magenta toner cartridge, part number 106R03691, in the high-capacity fill for the Xerox Phaser 6510 colour laser — the same cartridge also serves the WorkCentre 6515. It is rated at up to 4,300 pages and priced at $26.02, about 0.61 cents per page, which suits a printer whose colour work carries the business's face: reds in logos and headings, charts that have to match the screen, handouts people keep. The cartridge arrives as one sealed unit, ready to install, and it is backed by our 1-year warranty and 1-year free returns. The rest of the range is in our Xerox toner collection, and weekday help runs Monday to Friday, 9 AM to 5 PM CST.
