Phaser 7750B

The Xerox Phaser 7750B is a color laser printer from the Phaser line, equally at home printing single pages or long multi-page sets. Each color slot has its own cartridge — black 106R00652, cyan 106R00653, magenta 106R00654 and yellow 106R00655 — and the printer's 108R00581 imaging drum is a separate unit replaced on a longer interval than any toner.

Long multi-page work changes how a printer consumes its supplies. A 7750B fed on reports and document sets chews through black steadily, touches colors unevenly depending on the documents, and asks for a drum only after a long accumulation of pages. Buying for that pattern means watching two clocks at once: the fast toner clock, best answered slot by slot, and the slow drum clock, which should be answered on evidence — print quality — rather than on a guess or a bundle.

The drum is sold separately as the 108R00581 imaging drum unit.

Which cartridge should you buy?

Buy toner by the slot and the drum by the symptom. In a long-document office, black empties on a fairly predictable rhythm, so a standing habit of keeping one 106R00652 in reserve works well; colors are better bought as they run low, since their pace depends entirely on what your documents carry. A 4 color set is the right call when the machine is new to you or when several slots converge on empty together. The drum is the purchase to slow down on: it is replaced on a longer interval than the toner, and its need announces itself through the pages — gray backgrounds, washed density — not through the toner warnings. Ordering it alongside routine toner, out of habit, spends money quarters before it is needed.

Chip, toner and everyday use

Chips in the toner cartridges feed the printer's level estimates, which are built from page counts at standard coverage; a month of dense document sets will pull real life ahead of those estimates, so take an early low warning on a hard-working 7750B seriously. When a cartridge fades, rock it gently to redistribute its toner and print on while its replacement ships. Keep the drum's role in mind during troubleshooting: if a brand-new cartridge prints no better than the old one, the drum has likely reached its turn. Spares store best sealed and flat in a cool place, and a swapped-out drum should be handled by its frame and kept out of bright light until it leaves the building.

Frequently Asked Questions

What toner does the Phaser 7750B use?

Black 106R00652, cyan 106R00653, magenta 106R00654 and yellow 106R00655 — one cartridge per slot, all listed on this page. The 108R00581 imaging drum is separate from all four.

Does the Phaser 7750B take the same cartridges as the Phaser 7750?

Yes. The B model shares the 7750 cartridge range — the same four toner numbers and the same 108R00581 drum — so stock bought for one machine serves the other.

How do I replace the toner cartridge in the Phaser 7750B?

With the printer powered on, open the toner access cover, pull the used cartridge out, rock the new one gently side to side, insert it firmly until seated, and close the cover. On a long print run, print a few test pages before releasing the full set.

How do I find the right toner for my Phaser 7750B?

Read the number on the label of the cartridge installed in the slot you are replacing and match it to the listings above. Numbers, not the model badge, are what separate the colors from each other.
